Genetic variability in wood and oleoresins traits of twenty six high resin yielders (HRYs) and ten check trees of Pinus roxburghii was studied. These traits were quantitatively measured for bark percentage of wood, specific gravity of wood, tracheid length, cold and hot water soluble extractives, alcohol-benzene extractives, lignin and holocellulose percentage of wood, number of resin ducts, diameter of resin ducts, needle length, needle thickness, turpentine percentage, specific gravity of turpentine, relative flow rate of turpentine, rosin percentage, specific gravity of rosin and ash percentage of rosin. The highest heritability was observed for hot water soluble extractives, lignin percentage of wood and rosin percentage followed by bark percentage of wood, cold water soluble extractives and turpentine percentage. The maximum genetic advance was recorded in rosin percentage followed by lignin percentage of wood. The highest genetic gain was obtained in bark percentage of wood preceded by number of resin ducts whereas, phenotypic and genotypic coefficient of variation was highest in number of resin ducts followed by bark percentage of wood. Hence, bark percentage of wood, tracheid length, cold and hot water soluble extractives, lignin percentage of wood, number of resin ducts, diameter of resin ducts, needle length, turpentine and rosin percentage should be considered as effective parameter for the selection of high resin yielders (HRYs) in Pinus roxburghii Sargent.

Macrophytic species diversity was studied in crude oil contaminated and non-contaminated sites within the Upper Burhidihing Reserve Forest. Species richness was 57 and 86 in contaminated and non-contaminated sites respectively. On the basis of importance value index (IVI), Cynodon dactylon (13.92), Cyperus cyperoides (12.75), Imperata cylindrica (10.01) were dominant ground-flora herbs in former sites. The IVI value of Axonopus compressus (7.90) was high in non-contaminated land. The distribution of most of macrophytes in contaminated areas was contiguous, in contrast to regular distribution of most of ground flora in other sites. The value of concentration of dominance (C) of the macrophytic flora at both sites was lower and index of diversity (H) was higher. The index of dissimilarity between the vegetation groups was high indicating the effect of crude oil contamination on vegetation.

Acacia auriculiformis grown as plantation in Sirsi, Karnataka, India has been evaluated for anatomical properties and basic density of wood in eight, ten and thirteen year old trees. Among different anatomical properties studied vessel element length, fibre length, fibre lumen diameter and percentage of vessel and rays showed significant differences in all the three age groups. Basic density was negatively correlated with fibre lumen diameter for all the age groups. Additionally significant correlations, both positive and negative were found between certain anatomical properties, ratios and factors. Basic density was negatively correlated with flexibility co-efficient and F%/ V% and positively correlated with shape factor that are useful for predicting the paper and pulp quality. Anatomical data suggest its usefulness in paper and pulp industry.

A nursery trial of Pinus wallichiana and Cupressus torulosa with nine different sowing dates spread over autumn, winter and spring was conducted during 2002-2003. Germination in case of Pinus wallichiana was better where seeds were sown in the month of February, but in Cupressus torulosa germination during December, February and first fortnight of March was uniform. Survival percentage of seedlings was more in seeds sown in the month of February. Time taken for completion of germination decreased as sowing proceeded from autumn to spring. Seedling development in terms of height and diameter was better in seeds sown on 15th of November (autumn), but seedlings obtained from 1st February sown seeds are also of comparable good quality. The study concluded that in order to get good germination, better survival, good quality seedlings and cost effective nursery seeds should be sown in the nursery in the first fortnight of February (winter), instead of sowing in autumn season as is normally practiced.

Based on rainfall, interception, runoff, evapotranspiration, capillary contribution, deep percolation and soil moisture storage in 1.5 m profile, water balance of three forest species namely, Acacia nilotica, Dalbergia sissoo and Leucaena leucocephala was estimated for the months during 2003-04, in their initial growth stage in fragile Shivalik foothill of Haryana. All these species survived well with 80-100 per cent survival rate. It has been found that all the three species extracted moisture up to 90 cm depth in initial 2-3 years of growth. Deep percolation losses from 1.5 m profile were significant during monsoon due to high incident of rainfall and high saturated hydraulic conductivity of light textured soil in that area. However, considerable capillary upward movement was noticed during summer. Dalbergia sissoo profiles hold more moisture than other two species.

This study investigates the effect of anthropogenic disturbances on tree community structure and their regeneration in Anaikatty hills, Western Ghats. The study was conducted in the reserve forests of Anaikatty hills and the adjoining Salim Ali Centre for Ornithology and Natural History (SACON) Campus. Three habitats namely undisturbed, moderately disturbed and highly disturbed stands were identified on the basis of various signs of disturbances such as lopping, cattle grazing, nearness to human habitation, collection of non-woody forest produces etc. The study revealed a higher level of disturbance, altered diversity and other characteristics. The community structure showed a picture of floristic change from Albizia amara - Cordia monoica - Canthium dicoccum to Pleiospermium alatum - Ehretia ovalifolia - Maba buxifolia to Chloroxylon swietenia - Prosopis juliflora - Albizia amara in different disturbance regimes. In all the stands, vegetation showed a trend of change from its original community structure. The regeneration of the area was affected badly in all the three stands.

Published: 01-09-2007
Acacia robusta, a multipurpose tree species produces hardcoated and dark brown colour seeds. Seed has physical dormancy due to hardiness of testa. Suitable pretreatment to break the dormancy was investigated. Germination was enhanced from 36.80% (untreated) to 92.00% (mechanical scarification). Although mechanical scarification treatment gives early, uniform and highest germination but it is not practicable in large-scale purposes. Therefore, hot water soaking for 24 hours or sulphuric acid for 15 minutes soaking is recommended.

The paper reports the floristic composition of four regenerating forest stands in the Kandhamal District of Orissa, India. Highest number of species (69) was observed in 2 years regenerating stand, which declined with increase in age. The number of species was 55, 55, and 51 in 4 years, 6 years and 10 years stands respectively. Altogether 87 species under 71 genera and 32 families were recorded in the forest stands. The change in the number of species with age is mainly due to the elimination of herb species in the undergrowth. Tree and shrub species maintain their number in all the stands.
