Changes in carbohydrate and ABA content during GA-induced growth of non-cooled tulip bulbs were investigated under the conditions reported previously (Geng et al., 2005) that GAsub(3) promotes the shoot growth and flowering of non-cooled tulip bulbs when planted in December but not in September. Rapid degradation of starch and the increase in soluble carbohydrate content in the floral stalk were observed during GAsub(3)-induced floral stalk elongation in non-cooled bulbs planted in December, but not in those planted in September. The growth of floral stalk promoted by GAsub(3) application was accompanied by the decrease in ABA content in the shoot of the non-cooled bulbs planted in December.
