Studies on seed viability and its effects on germination, growth and graft-take in medicinal fruit plant of Jamun

Abstract

Jamun is an important medicinal plant used in various traditional systems of medicine. An investigation was carried out on seed viability and its effects on germination, growth, root and graft-take in medicinal plant of Jamun. Among different days, seeds sowed at zero days after extraction got early initiation, 50% germination (15.74 and 22.55), Number of leaves (20.33) and stem diameter (5.37mm). whereas three days after extraction seeds recorded significantly maximum germination percentage (100%), germination index (2.45) extent of Polyembryony (3.59), Plant height (20.22 cm), primary root length (26.07 cm), numbers of secondary roots (44.61), volume of roots (5.64 ml), rootstock vigour (594.22 g), vigour index (2022.70 cm) and Survival percentages (64.26%). However six days after extraction recorded highest height (7.41 cm) and Per cent graft success (70.40%). The germination percentage decreased with increased storage period. For viable seeds maximum germination percent growth, root, vigour and graft parameter was recorded three days after extraction and lowest was recorded twenty four days after extraction seeds.
