Abstract

A study was carried out at the nursery of Biotechnology- cum-Tissue Culture Centre, OUAT, Bhubaneswar, India to evaluate the effect of different concentration of GA3 (i.e. Control, 700, 710, 720, 730, 740, 750, 760, 770, 780, 790, 800 ppm ) respectively on seed germination in Delonix regia was determined. Seeds treated with of GA3 at 790 ppm gives maximum germination (76.67 %), mean daily germination (4.79), peak value (5.50) and germination value (24.92). Therefore it may be concluded that seeds treated with GA3 at 790 ppm can be recommended for obtaining better seed germination of Delonix regia.
