研究表明,巨峰葡萄成熟种子种壳含有很高的ABA或类似物.用40%石灰氮浸出液处理18h打破休眠的效果最好.葡萄童期阶段细胞分裂素含量低,并且随节位升高变化迟缓,当临近阶段转变时,含量急剧上升.GA_3含量童期阶段高于转变期.GA_(4+7)在阶段转变部位含量急剧下降,CTK/GA_3急剧上升.生长素含量在童期阶段随着节位升高急剧增加,临近阶段转变时含量又急剧降低.脱落酸的含量则随着节位升高有缓慢上升的趋势.
Studies have shown that Kyoho grapes mature seed shell contains high levels of ABA or similar.With 40% lime nitrogen leaching solution for 18h to break dormancy best.Plasma cytokinin content during childhood is low, and with the increase of the pitch changes The content of GA 3 was higher than that of the transitional period.GA_ (4 + 7) decreased sharply at the stage of transition and the content of CTK / GA 3 rose sharply The sharp rise of knot position increased sharply and the content of abscisic acid decreased sharply during the transitional period.And the content of abscisic acid gradually increased with the rise of knot position.
