INFLUENCE OF GA3 AND CHARCOAL ON IN VITRO SEED GERMINATION OF TERMINALIA ARJUNA

T. Vijaya, P.Sujathamma, G.Savithri

Abstract

Terminalia arjuna is a deciduous tree belongs to the family combretaceae. The leaves of this tree is fed to tasar silk worm Anthereae mylitta to rear tasar silk, one of the traditional silks of India. The bark is used in Ayurveda from ancient days. The tree multiplied only via seeds collected from forest. Seed germination in Terminalia arjuna is very difficult because of hard seed coat, high heterozygosity, seed dormancy and high phenoloic compounds. To conquer this for conservation of this valuable tree a protocol is developed for increasing the rate of in vitro seed germination. The seeds soaked in GA-3 (100 ppm) solution for 24h and inoculated in MS medium by supplemented with charcoal (100 mg/lit) resulted high percentage of seed germination.
