Abstract

The effects of BA, ethephon, and GA 3 on freshly harvested cormels of three cultivars of Gladiolus sp. were studied for 3 years. The treatment with 400 mg·L -1 ethephon significantly reduced the dormancy period by 17.5 days as compared to control, while BA and GA 3 were found to be less effective. Among all treatments, ethepon at 400 mg·L -1 was found to be the most effective in altering the days to sprout, sprouting percentage, corm size and production and development of cormels. While GA 3 at 100 mg·L -1 increased growth of corms and cormels, BA at 25 mg·L -1 increased growth of corms and cormels. BA at 25 mg·L -1 only influenced the sprouting percentage of cormels. Along with reducing the dormancy period, the plant growth regulators stimulated growth and development of corms and cormels. Chemical names used: benzyladenine (BA); 2-chloroethylphosphonic acid (ethephon); gibberellic acid (GA 3 ).
