The purpose of this experiment was to reduce the schedule of cut mum production by decreasing the number weeks of long days and supplementing the flowers with the plant hormone gibberellic acid (GA). GA is a plant hormone which enlarges the cells of the stems and could conceivably affect mum vegetative growth during long days. In this experiment, long days were reduced to 0, 3, 10, 13, 17 and 20. During the long day treatments, different rates of products were applied. Both ProGibb 4% and Fascination were used to look at the effects of the different variations of GA; GA3, GA4, and GA7.
