Seed Source Variability in Terminalia arjuna (Roxb.) W.&A. and Terminalia tomentosa W.&A.
Abstract
Terminalia arjuna and T. tomentosa are perennial and hard wood trees and are of tremendous economic importance besides primary food plants of tasar silkworm Antheraea mylitta D. Seeds are the principal source of natural regeneration and propagation in these species. A wide variation for twelve seed traits was observed in different seed sources of diverse origin in both the species collected from various locations. A positive and significant correlation was found between seed germination and seed weight, total biomass production and vigour index. On the other hand, a negative and significant correlation was recorded for days taken for initial germination and complete germination with width of wings. Present study will help in identification of genotypes that can be propagated at mass scale through seedlings.
