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.

摘要： 在对布兰瑞克无花果花芽分化形态学研究的基础上, 对花芽分化期无花果新梢第7 或第8 节位芽中植物激素的玉米素核苷(ZR)、脱落酸(ABA) 、赤霉素(GA1+3 )、生长素( IAA) 含量的变化进行了研究。结果表明, 在花托和小花形成阶段, 芽内需要较高水平的ZR、ABA 和较低水平的GA1₊₃ 、IAA。在花托和小花的形成阶段, ABA􊄯IAA, ABA􊄯GA1₊₃ , ZR􊄯GA1₊₃ 和ZR􊄯IAA 都有较高的比值。
