Abstract:

Agar scientifically known as Aquilaria malaccensis Lamk, belonging to the family Thymelaeceae. The species is included in the Convention on International Trade in Endangered Species of Wild Fauna and Flora (CITES 1994). The species is also listed as ‘Vulnerable’ globally, ‘Critically Endangered’ in India (IUCN 2009).It is an economically important native tree species of sub tropical-tropical rainforests of northeast India. Study was carried out in the Department of Forestry during 2015-2017. The aim of this investigation was to measure the variability of seed traits. Field survey was carried out across the population of Aquilaria malaccensis throughout Mizoram, Nagaland, Assam, West Bengal and Tripura to select well represented nineteen seed sources viz. Basistha, Ganakpokhari, Hathipara, Hmarveng, Hybergyon, Islam nagar, Kumar ghat, Lanka, Lonigodam, Nagariborline, Naharani, Namti, Nazari, Nelbagan, Newdiakkawan, Rajabhatkhawa, Sephizala, Sukhana and Thahekhu. The trees of approximately same age group were randomly selected and visual assessment viz. tree height, clean bole, good crown spread healthy tree and geographical variation. Collected capsule of each respective seed sources were mixed to make it a composite sample for studying the capsule and seed traits viz. Length of capsule (25.24-32.53 mm), Width of capsule (14.25-18.14 mm), Thickness of capsule (10.73-14.84 mm), Wt. of 100 of capsule (215.67-291.68 g), Length of seed (13.65-16.61 mm), Width of seed (4.42-5.06 mm), No of seeds / capsule, Wt. of 100 seeds (10.35-12.40 g) and moisture content of seed was recorded Significant variations (CD=0.05).
