Dominic Sahaya Rajan R.*, Stella C. and Siva J. and Gokila S.
Background: Aim: To find out the influence of seed germination activity on Phaseolus radiata L by seagrass extracts, gibberellic acid and naphthalene acetic acid. Materials and Method: The present study was conducted during rabi season 2016-2017 using healthy seeds of green gram. Grouped into five different strata including control group. The parameters include the number of seeds germinated, percentage of germination after 12 days, % Survival after 14 days, the seeding height, shoot length, root length, root/shoot ratio and thickness (width length) of young leaf of survived plant were measured and compared. Result: Seed germination or plant growth was justified on the basis of parameters such as percentage of germination, survival, seedling height, shoot length, root length, root/shoot ratio and thickness of young leaf Conclusion: The seed germination activity of seagrass extracts (Thalassia hemprichii) with gibberellic acid and naphthalene acetic acid on Phaseolus radiata L have been studied at 50ppm and 100ppm. Foliar applications of seagrass extracts and gibberellic acid 50 ppm were found to be superior in seed germination by measurement of parameters like percentage of germination, survival, seedling height, shoot length, root length, root/shoot ratio and width of young leaf.
Keywords: Gibberellic acid, Naphthalene acetic acid, Thalassia hemprichii, Phaseolus radiata L.
