Association Analysis for Morphological and Biomass Traits in Albizzia lebbeck Seedlings

Abstract

Seeds of Albizzia lebbeck Benth from 20 different seed sources were collected from different eco-geographic regions
of Uttar Pradesh to study of the morphological and biomass traits in the experimental area of the school of Forestry
and Environment, green house and natural field conditions. The traits studied were seedling height, collar diameter,
internodal length, branches/seedling, leaf area, shoot and root fresh and dry weight, shoot/root ratio and seedling
biomass. Out of total 55 correlation combinations in both environments, 26 and 10 were positive and highly significant,
10 and 9 positive and significant. Seedling height showed positive and significant correlation with collar diameter,
leaf area, shoot fresh weight and root dry weight. Shoot dry weight and root dry weight showed positive and significant
correlation with seedling biomass under both environments. This suggests that there exits a strong inherent association
between these characters
