摘要: 为了探明银杏Ginkgo biloba 雌花芽分化的生理机制, 用酶联免疫等方法对银杏雌花芽分化期间内源激素、碳水化合物和矿质营养含量的变化进行了研究。结果表明, 银杏雌花芽在生理分化期(花芽诱导期), 花芽中赤霉素(GA1 +3)和脱落酸(ABA )质量摩尔浓度下降, 玉米素(ZRs)、异戊烯基腺嘌呤类(iPAs )质量摩尔浓度出现峰值, ZRs/GA1 +3 , ABA/GA1 +3 及iAPs/GA1 +3的值也出现峰值。随着形态分化的开始, ZRs 和iPAs 的质量摩尔浓度、ZRs/GA1 +3和iPAs/GA1 +3 的值下降, 并维持较低水平。雌花芽中的ABA 质量摩尔浓度、ABA/GA1 +3的值在高于雌叶芽的水平上波动。银杏雌花芽分化过程中, 雌花芽叶中钾和淀粉质量分数均高于同期雌叶芽叶的质量分数;而雌花芽叶全氮的质量分数基本低于同期雌叶芽叶全氮水平;在生理分化期中雌花芽叶内磷质量分数均高于叶芽叶质量分数。说明银杏雌花芽分化过程中, ABA , ZRs , iPAs 及钾和银杏雌花芽的诱导及分化密切相关。图11 参16

Abstract: In order to find out the physiological mechanism of female flower buds differentiation in Ginkgo biloba , the changes of endongenous hormones , carbohydrate and mineral nutritions during the differentiation of female flower buds were studied with the methods of ELISA and et al .Results showed that the contents of GA 1 +3 and ABA in female flower buds of Ginkgo biloba at the physiological differentiation stage decreased , the contents of ZRs and iPAs , the ratio of ZRs to GA 1+3 , the ratio of ABA to GA 1 +3 and the ratio of iPAs to GA 1 +3 were at peak values .At morphological differentiation stage , the contents of ZRs and iPAs , the ratio of ZRs to GA 1 +3 and the ratio of iPAs to GA 1 +3 were low , but the contents of ABA and the ratio of ABA to GA 1+3 in flower buds were higher than those in leaf buds .The contents of K and total carbohydrate in bud leaves of female flowers were higher than those in bud leaves of female shoots during the whole period ;while the content of total N in bud leaves of female flowers was lower than that of bud leaves of female shoots .The content of P in bud leaves of female flowers was higher than that in bud leaves of female shoots at physiological differentiation stage .Results indicated that the contents of ABA , ZRs , iPAs and K were associated with inducement and differentiation of female flower buds of Ginkgo biloba .
