NOR HASNIDA Hassan The complex of two tungro viruses, the rice tungro bacilliform virus (RTBV) and rice tungro spherical virus (RTSV) were purified using the phenol-chloroform technique and showed multiple bands when electrophoresed with agarose gel conforming the behaviour of circular DNA molecule. Amplication of the putative protease gene fragment through the polymerase chain reaction (PCR) was carried out using the DNA preparation as template and the sequences 5' ACT CTA GAA TGA TAA CAG CCC TAA TAG AT 3' as primer 1 and primer 2. The primers were designed to contain restriction sites of Bam HI and Xba I as well as codons for translation initiation and termination. The resulting putative DNA fragment for protease gene had a size of about 1.1 kb after electrophoresis in agarose gel. Following digestion of the respective sites with Bam HI and Xba I, both the PCR product and the pUC 18 and pUC 19 plasmids were incubated at 70°C and then mixed together for the ligation process and then transformed into E. coli JM 109. Insert DNA molecule was subcloned into pBI 121 which was then used for transformation of E. coli JM 109. Three selected clones were used for triparental mating to mobilize the plasmid containing putative protease gene into Agrobacterium tumefaciens with the help of helper plasmid pRK 2013 in E. coli HB 101. Transformation of rice variety IR 52 and MR 81 rice seedling with three clones of A. tumefaciens, which are pBI 121 150s (6), pBI 121 60s (8) and pBI 121 60s (9) resulted in the transfer of GUS gene fusion cassette into the seedling tissues. This was evident from the presence of blue colour in the tissues following GUS transient assay.
LIEW Kang Chiang Natural lignocellulosic fibres have become more important nowadays because "new" types of composite material can be produced from them. The objectives of this study are to evaluate the suitability of producing fibre-polypropylene composite using oil palm frond fibre and rubberwood fibre. The effects of different fibre size and fibre content on the physical and mechanical properties of the composite produced are assessed to give an insight into fibre-matrix adhesion and fibre damages. In this study, crude fibres of oil palm fronds were atmospherically refined into fine fibres whilst rubberwoood fibres were obtained from a local fibreboard plant. These fibres were later screened into different sizes: 0.5mm, 0.5-1mm, 1-2mm and 2mm. The screened fibres were melt-blended with polypropylene at different ratios in a Brabender Plasti-Corder equipped with a mixer of type W 350 E - 2 Heating Zones. The mixing condition was set at a rotor speed of 30 rpm at 180°C for 30 minutes. Moulded composites were prepared for evaluation of tensile, flexural, IZOD impact resistance - notched and ROCKWELL hardness according to ASTM standards. Results indicate that both oil palm frond and rubberwood composites showed reduction in tensile strengths but increment in tensile modulus as fibre content increase. Oil palm frond composite possessed higher tensile strength and modulus than rubberwood composite. As fibre size increased, the strength of both types of composites also increased. Flexural modulus for oil palm frond and rubberwood composites increased with fibre content. Rubberwood composite using coarser fibre sizes (1-2mm, 2mm) exhibit higher modulus. Unlike rubberwood, oil palm frond composite shows higher modulus when finer (0.5mm, 0.5-1mm) fibres were used. IZOD impact resistance - notched test piece showed a decreasing impact for oil palm frond composite as the fibre content increases but rubberwood composite experienced the opposite effect. An increase in fibre size increases the impact strength of both types of composites. ROCKWELL hardness decreased for oil palm frond and rubberwood composites as fibre content and fibre size increases. All evaluations are statistically analysed at p0.05. Supportive photographic evidences of the above results are shown by Scanning Electron Micrographs.

LARDIZABAL Maria Lourdes T. Azadirachta excelsa Jack. is a fast growing timber species that has been newly chosen as a potential forest plantation species to overcome timber deficit for domestic consumption in future. This species like Azadirachta indica is suspected to contain biologically active compounds that is detrimental on insects. Many studies have been done on the A. indica, a relative species to A. excelsa, however, studies on A. excelsa are still in preliminary stages. Therefore, the aim of this study was to evaluate the effect of A. excelsa crude extractives towards three selected insect pests, (i.e. Spodoptera litura, Callosobruchus chinensis and Coptotermes curvignathus). A preliminary test to evaluate the susceptibility of A. excelsa wood towards termites, compared to Koompasia malaccensis, Hevea brasiliensis and Pinus caribaea was also conducted. In the first part of the study, the A. excelsa plant extracts were extracted from different plant parts (i.e. leaf, bark, trunk, twigs and branch) using a range of polar to non-polar solvents, namely hexane, petroleum ether, toluene, ethyl acetate and methanol. The plant extractives were sampled and analysed through Thin Layer Chromatography (TCL) and Infrared Spectrocopy (IR). In the second part of the study, bioassay tests were conducted on the selected insects. The insects were exposed to the plant extractives prepared at three concentration levels (i.e. 250ppm, 500ppm and 1000ppm) and the solvents (0ppm) as the control, by feeding the insects with treated food source. The S. litura larvae were fed with castor leaf discs soaked in the respective extractives. The C. chinensis adults were exposed to mungbean seeds that had been soaked in the plant extractives while the C. curvignathus were fed with treated filter paper. In the last part of this study, the A. excelsa wood together with the other three wood species mentioned earlier, were exposed to the termites both in the laboratory and field. The TLC and IR results on the A. excelsa extractives showed that extractives from the different plant parts contained more non-polar chemical compounds. Among the five plant parts, the leaf contained the highest number of chemical compounds. The functional groups that were identified in the methanol and hexane extracts of leaf, bark and twigs, were hydroxyl, carboxyl, aromatic and unsaturated aldehydes. The bioassay on S. litura showed that the larvae consumed less leaf discs that were treated with higher concentration of extractive. Mortality mostly occured at the early larval stages. Although less mortality occured at the lower concentration, but the moulting and larval periods were extended to twice the normal period and thus the larvae consumed more leaf discs. However, the growth parameters (i.e. head capsule measurement and pupal weight) at the last instar stage was not effected by the treatments. Generally, bark extract caused a higher mortality and less food consumption compared to the leaf extract. The A. excelsa crude extract was not a good protectant on mungbean seeds. Results obtained from the treatments show that the oviposition rate and percentage adult emergence were not significant. The termites bioassay test showed that A. excelsa extractives caused high termite mortality coupled with less consumption on filter paper treated with bark extracts. Choice feeding test on wood blocks from four different species showed that A. excelsa was the least preferred wood species compared to the other species, both in the field and laboratory trials.
LEHTIJARVI Asko Among the endophytic microfungi colonizing Norway spruce, the non-pathogenic species Lophodermium piceae and Tryblidiopsis pinastri are ubiquitous. Most Norway spruce in Sweden are colonized by these fungi. L. piceae colonizes healthy needles of various ages, while T. pinastri colonizes the bark of branches. New shoots become infected around the time of their emergence. Fruit bodies are formed after the needles and branches die ...

LINDER Per The remnants of unexploited forests in Sweden are mainy found in forest reserves, which are designed to preserve natural habitats. However, data on the present characteristics of the reserves is limited. The aim of this disssertation is to elucidate stand structure of forest reserves, including structural changes currently in progress, and to compare it with stand features of the former natural forest landscape.

ONG Kian Huat Azadirachta excelsa (Jack) Jacobs is a fast growing multi-purpose tree species and is one of the species that is being promoted for planting in Malaysia. However, the silvicultural requirements of the species have not been well defined. The objective of this study was to evaluate the effects of fertilizers, mycorrhizal inoculation and mixed planting with Acacia mangium Willd seedlings on the growth and physiological changes of A. excelsa seedlings on Rengam series oil. The study consisted of two components. The pot trial examined the physiological changes and growth performance of A. excelsa seedlings in response to various fertilizer and mycorrhizal treatment using soil collected from the field. The field trial examined the seedling performace under field conditions when applied with fertilizer and mycorrhizal treatments, as well as mixed planted with A. mangium. Results from the four month pot trial showed that fertilized seedlings grew better than the control plants. Among the fertilizer treatments, Best-Tab slow release fertilizer (20-10-5 NPK with expanded minor and secondary element in 21 g tablet) promoted the best growth with maximum photosynthesis, followed by 40 g of NPK fertilizer (15-15-15 fertilizer (15-15-15 NPK) and finally 20 g of NPK fertilizer (15-15-15 NPK). In contrast, mycorrhizal application failed to promote seedling growth in a similar way. Similarly, combination of treatments failed to improve seedling growth as compared to either slow release fertilizer or NPK fertilizer alone. The higher the application of fertilizer, the higher the concentration of nutrient accumulated in the plant. This was demonstrated by the application of 40 g of NPK fertilizer. However, the nutrient accumulation failed to increase the photosynthetic rate of the seedlings. Nutrient analysis revealed that magnesium was an important element in promoting a higher rate of photosynthesis. Seedlings with a lower rate of growth were found to record a higher plant starch content. Application of fertilizer was found to reduce root infection by arbuscular mycorrhizal fungi. The results from the field study were similar to those of the pot trial. Best Tab slow release fertilizer was still the best in terms of promoting the growth of A. excelsa seedlings. Mycorrhizal treated seedlings without any fertilizer showed growth depression while mix planting did not show any positive effect. The rates of photosynthesis recorded in the field comparable to earlier published works on fast-growing species in Malaysia. In conclusion, growth of A. excelsa seedlings was found to be affected by mycorrhiza and fertilizer. The implications of these factors on the establishment of A. excelsa plantation are discussed.
ROSLAN Mohamad Knowledge on anatomical, physical and mechanical properties of wood is necessary in assessing the potential utilisation of wood. The main objectives of this study are to determine the cellular composition and anatomical variations of juvenile rubberwood (Hevea brasiliensis) and their extent in the selected clones and age groups. Another objective is to determine the structure of juvenile wood in relation to physical and mechanincal properties. Three different clones, PB 359, PB 366 and RRIM 600 from two age groups, namely 10 and 22 years old were selected from Golden Hope Plantation Bhd. Three trees were felled for each clone and age group. Each tree was divided into three portions along the height namely, stump (S1), trunk (S3) and branch (S5). Outer and inner samples along the radial position were chosen for comparative studies on the anatomical, physical and mechanical properties. All samples for each test were prepared in accordance with the British Standard (BS 373: 1957) specifications. Juvenile wood from the 10 year old, Hevea trees of the clones PB 359 exhibited the highest values for fibre length (1152.16æm) and initial moisture content (60.36). Clone PB 366 showed the highest values in fibre proportion (53.83), MOR (112.49N/mm²), MOE (9149.90N/mm²), and compression parallel to grain (50.64N/mm²) whereas RRIM 600 possessed the highest value in fibre diameter (25.27æm), lumen diameter (12.28æm), shear parallel to grain (17.87N/mm²), tangential shrinkage (2.13) and radial shringkage (0.99 ). For mature wood of 22-year old, clone PB 359 showed the highest values in fibre length (1248.69æm), initial moisture content (65.96), radial (0.69) and longitudinal shringkage (0.34). Clone PB 366 possessed the highest value in fibre proportion (47.32) and MOR (137.60N/mm²), whereas clone RRIM 600 showed the highest value in fibre diameter (24.61æm), specific gravity (0.61g/cm³), tangential shringkage (1.49), MOE (10422.48N/mm²), compression parallel to grain (64.05N/mm²) and shear parallel to grain (20.57N/mm²). All clones from the 22 year old age groups showed higher values for the fibre length, proportion of rays, moisture content, specific gravity, MOR, MOE, compression and shear parallel to grain when compared to similar clones from the 10 year old age group. For both age groups, the values for fibre length, fibre diameter, lumen diameter, cell wall thickness, vessel diameter, proportion of rays, specific gravity, MOR, MOE, compression and shear parallel to grain at the trunk (S3) section were higher compared to the stump (S1) and branch (S5) sections. The mechanical strength of the wood was found to be affected by fibre length, fibre diameter, cell wall thickness, proportion of fibres and specific gravity. Based on mechanical strength, 10 year old juvenile rubberwood is suitable for the manufacturing of pulp and paper, solid wood products and medium-density fibreboard. Clone PB 366 is suitable for sawn timber due to the superior mechanical strength. Clone PB 359 can be processed to pulp and paper due to its lower lignin content and higher alphacellulose and hemicellulose contents. Branch wood (S5) possess similar anatomical, physical and mechanical properties to the trunk (S3), and is considered is suitable for sawn timber due to the superior mechanical strength. Clone PB 359 can be processed to pulp and paper due to its lower lignin content and higher alphacellulose and hemicellulose contents. Branch wood (S5) posses similar anatomical, physical and mechanical properties to the trunk (S3), and is also considered suitable for industrial utilisation. The stump (S1), however possess lower mechanical strength properties and is not recommended for industrial utilisation.
RYDBERG Dan Urban forestry in Sweden used to be recognised as urban fringe forestry, but a focus on forest ecosystems in the fringe of, as well as inside, urban areas would be a more useful restriction. Based on a classification of the urban forests into five zones, depending of their use and size, future improvements in urban forestry are suggested.
SABALA Izabela Embryo development is a complex process involving a set of strictly regulated events. The regulation of these events is poorly understood especially during the early stages of embryo development. Somatic embryos go through the same developmental stages as zygotic embryos making them an ideal model system for studying the regulation of embryo development. We have used embryogenic cultures of Picea abies to study some aspects of the regulation of embryo development in gymnosperms.

In the first part of the study, the A. excelsa plant extracts were extracted from different plant parts (i.e. leaf, bark, trunk, twigs and branch) using a range of polar to non-polar solvents, namely hexane, petroleum ether, toluene, ethyl acetate and methanol. The plant extractives were sampled and analysed through Thin Layer Chromatography (TCL) and Infrared Spectrocopy (IR). In the second part of the study, bioassay tests were conducted on the selected insects. The insects were exposed to the plant extractives prepared at three concentration levels (i.e. 250 ppm, 500 ppm and 1000 ppm) and the solvents (0 ppm) as the control, by feeding the insects with treated food source. The S. litura larvae were fed with castor leaf discs soaked in the respective extractives. The C. chinensis adults were exposed to mungbean seeds that had been soaked in the plant extractives while the C. curvignathus were fed with treated filter paper. In the last part of this study, the A. excelsa wood together with the other three wood species mentioned earlier, were exposed to the termites both in the laboratory and field. The TLC and IR results on the A. excelsa extractives showed that extractives from the different plant parts contained more non-polar chemical compounds. Among the five plant parts, the leaf contained the highest number of chemical compounds. The functional groups that were identified in the methanol and hexane extracts of leaf, bark and twigs, were hydroxyl, carboxyl, aromatic and unsaturated aldehydes. The bioassay on S. litura showed that the larvae consumed less leaf discs that were treated with higher concentration of extractive. Mortality mostly occured at the early larval stages. Although less mortality occured at the lower concentration, but the moulting and larval periods were extended to twice the normal period and thus the larvae consumed more leaf discs. However, the growth parameters (i.e. head capsule measurement and pupal weight) at the last instar stage was not effected by the treatments. Generally, bark extract caused a higher mortality and less food consumption compared to the leaf extract. The A. excelsa crude extract was not a good protectant on mungbean seeds. Results obtained from the treatments show that the oviposition rate and percentage adult emergence were not significant. The termites bioassay test showed that A. excelsa extractives caused high termite mortality coupled with less consumption on filter paper treated with bark extracts. Choice feeding test on wood blocks from four different species showed that A. excelsa was the least preferred wood species compared to the other species, both in the field and laboratory trials.

ROSLAN Mohamad Knowledge on anatomical, physical and mechanical properties of wood is necessary in assessing the potential utilisation of wood. The main objectives of this study are to determine the cellular composition and anatomical variations of juvenile rubberwood (Hevea brasiliensis) and their extent in the selected clones and age groups. Another objective is to determine the structure of juvenile wood in relation to physical and mechanincal properties. Three different clones, PB 359, PB 366 and RRIM 600 from two age groups, namely 10 and 22 years old were selected from Golden Hope Plantation Bhd. Three trees were felled for each clone and age group. Each tree was divided into three portions along the height namely, stump (S1), trunk (S3) and branch (S5). Outer and inner samples along the radial position were chosen for comparative studies on the anatomical, physical and mechanical properties. All samples for each test were prepared in accordance with the British Standard (BS 373: 1957) specifications. Juvenile wood from the 10 year old, Hevea trees of the clones PB 359 exhibited the highest values for fibre length (1152.16æm) and initial moisture content (60.36). Clone PB 366 showed the highest values in fibre proportion (53.83), MOR (112.49N/mm²), MOE (9149.90N/mm²), and compression parallel to grain (50.64N/mm²) whereas RRIM 600 possessed the highest value in fibre diameter (25.27æm), lumen diameter (12.28æm), shear parallel to grain (17.87N/mm²), tangential shrinkage (2.13) and radial shringkage (0.99 ). For mature wood of 22-year old, clone PB 359 showed the highest values in fibre length (1248.69æm), initial moisture content (65.96), radial (0.69) and longitudinal shringkage (0.34). Clone PB 366 possessed the highest value in fibre proportion (47.32) and MOR (137.60N/mm²), whereas clone RRIM 600 showed the highest value in fibre diameter (24.61æm), specific gravity (0.61g/cm³), tangential shringkage (1.49), MOE (10422.48N/mm²), compression parallel to grain (64.05N/mm²) and shear parallel to grain (20.57N/mm²). All clones from the 22 year old age groups showed higher values for the fibre length, proportion of rays, moisture content, specific gravity, MOR, MOE, compression and shear parallel to grain when compared to similar clones from the 10 year old age group. For both age groups, the values for fibre length, fibre diameter, lumen diameter, cell wall thickness, vessel diameter, proportion of rays, specific gravity, MOR, MOE, compression and shear parallel to grain at the trunk (S3) section were higher compared to the stump (S1) and branch (S5) sections. The mechanical strength of the wood was found to be affected by fibre length, fibre diameter, cell wall thickness, proportion of fibres and specific gravity. Based on mechanical strength, 10 year old juvenile rubberwood is suitable for the manufacturing of pulp and paper, solid wood products and medium-density fibreboard. Clone PB 366 is suitable for sawn timber due to the superior mechanical strength. Clone PB 359 can be processed to pulp and paper due to its lower lignin content and higher alphacellulose and hemicellulose contents. Branch wood (S5) possess similar anatomical, physical and mechanical properties to the trunk (S3), and is considered is suitable for sawn timber due to the superior mechanical strength. Clone PB 359 can be processed to pulp and paper due to its lower lignin content and higher alphacellulose and hemicellulose contents. Branch wood (S5) posses similar anatomical, physical and mechanical properties to the trunk (S3), and is also considered suitable for industrial utilisation. The stump (S1), however possess lower mechanical strength properties and is not recommended for industrial utilisation.

RYDBERG Dan Urban forestry in Sweden used to be recognised as urban fringe forestry, but a focus on forest ecosystems in the fringe of, as well as inside, urban areas would be a more useful restriction. Based on a classification of the urban forests into five zones, depending of their use and size, future improvements in urban forestry are suggested.
