Chlormequat (Cycocel), daminozide (Alar), ethephon (Ethrel) and maleic hydrazide were applied to cardamom seedlings (3, 5 and 7 months old) to encourage sucker production. The application of 250 p.p.m. chlormequat, 500 p.p.m. daminozide, 100 p.p.m. ethephon or 250 p.p.m. maleic hydrazide significantly increased the sucker production and improved other vegetative characteristics when applied to 7-month-old seedlings. The cost:benefit ratio from maleic hydrazide treatment was calculated and found to be economic.
