In a field experiment at Pune in 1992-93, chrysanthemums were planted in the first week of May, June or July and sprayed twice (30 and 50 days after planting) with 10, 20 or 30 ppm IAA, 50, 100 or 150 ppm GA or 150, 300 or 450 ppm maleic hydrazide. Cut flower yields were highest from May plantings. Of the growth regulator treatments, 50 ppm GA and 20 ppm IAA gave the highest yields. The number of days to 50% flowering was least from planting in July and following application of 20 ppm IAA.
