Effect of cytokinin and gibberelin on lettuce seeds germination
Abstract
This study was about germination of Lettuce (Lactuca sativa) performed in Azad Islamic university Shirvan branch and effects of cytokinin and gibberellin soaking were investigated in a Randomized Complete Block Design with factorial treatment structure in four replications. The solutions of cytokinin and gibberellin were prepared at 2, 4, 6 and 8 ppm levels and 1000 seed were soaked in solutions. The effects of applied hormones and the concentrations of hormone solutions were significant (0.01%). Soaking the seeds in 8 and 6 ppm of cytokinin solutions had the highest effect on duration of radicles growth (7.75 and 5.5 days respectively) and also using 8 ppm of cytokinin solution had the highest effect on duration of hypocotylesgrowth (14 days).
