Abstract

Easy ischolar_mainability being an important criterion for selection of superior trees for mass-multiplication, ischolar_maining of juvenile cuttings from nine month old half-sib progenies of selected trees were taken up, which revealed significant differences in ischolar_maining responses along with other traits. It was observed that progenies of C1, C2 and C3 trees performed best. Correlation among all the characters were found to be sufficiently high and the parent-progeny correlation revealed significant positive relationships between DBH x Number of leaves and Height x Number of leaves. Further investigations on mature-juvenile relationships based on number of leaves in seedlings may be necessary.

Abstract

A study was conducted to find out the magnitude of regenerated shoot production (coppicing ability) after pruning in Eucalyptus (Mysore-gum). Shoot prunings were grouped at four height classes. Number of shoots regenerated after pruning were counted on individual plant basis. An analysis of variance showed that the four groups of pruning levels produced significantly different number of shoots. As the pruning height-level increased gradually, the mean number of shoot production decreased along with a decrease in variation. Increase in mean and variation at the lower level was possibly due due to the increased ischolar_main-system influence or the juvenility at that Jevel. The highest mean for shoot production was obtained at < 10 cm beight of pruning. It was concluded. That pruning of Eucalyptus (Mysore-gum) plants be made at less than 10 cm level to produce maximum number of shoots for the establishment of a hedge-garden from which large number of cuttings may be made available to produce ischolar_mained-cuttings in a mass-scale for clonal forestry purposes.

Abstract

In tbe present paper Volume Table for Alnus nepalensls bas been prepared on the standard method or regression but special emphasis bas been put to a great extent to overcome the difficulties in finding out the best fit volume equation. For this an Index known as Fernival Index has been used for comparing the statistics or transformed and nontransformed equations.

Abstract

Provisional volume tables for Pinus caribaea and Pinus patula have been prepared. Use has been made of 'Cosh function' as independent variable to improve volume (V) prediction by V=a+b D²H regression over entire data range, where D Is diameter at breast height and H Is height of a tree.

Abstract

The growth of Cryptomeria japonica has been quoted in the past with reference to specific localities but no attempt was made to estimate its Growth in different productive sites. The paper presents growth pattern of Cryptomeria under varying conditions.

Abstract

Estimation of permanent sample plot volume with accuracy depends upon correct selection of sample trees. Unbiased selection of sample trees by point sample and systematic sample method have been discussed and it is found systematic sample method in case of Pinus patula plantation 11 year old yields estimate within an error of 2%.
