Abstract: Based on the morphological results of the flower bud differentiation in Ficus carica L.‘Brunswick', we quantified certain plant hormones, including ZR, ABA, GA1+3 and IAA, in the developing flower bud at the differentiation stage
on the seventh or the eighth node of the new shoots, and found that at the stage of floral receptacle and floscule formation, the buds contained high level of ZR and ABA, and low level of GA1+3 and IAA, leading to a high ratio of ABA to IAA, ABA to GA1+3 ZR to GA1+3 , and ZR to IAA, respectively.

Key words: Ficus carica
