Berries on field-grown Vitis vinifera cv. Doradillo were treated at different times during stage II with benzothiazole-2-oxyacetic acid or 2-chloroethylphosphonic acid, and measurements were made of their growth and hormone content. The concentration of ethylene was low during stage II and declined as berries ripened. Both 2-chloroethylphosphonic acid and benzothiazole-2-oxyacetic acid caused increases in ethylene concentration, yet they had varying effects on ripening: the former applied at the start of stage II and the latter applied 1 week before the end of stage II delayed ripening, while 2-chloroethylphosphonic acid applied at the end of stage II hastened ripening.The abscisic acid content of berries increased as they ripened, and the effects of 2-chloroethylphosphonic acid and benzothiazole-2-oxyacetic acid on abscisic acid levels were correlated with the effect of these compounds on ripening. The roles of abscisic acid and ethylene in the regulation of the ripening of grapes are discussed.
田间生长的葡萄品种 Doradillo 的浆果在第二阶段的不同时间用苯并噻唑-2-氧乙酸或 2-氯乙基膦酸处理,并测量其生长和激素含量。第二阶段乙烯浓度较低,随着浆果成熟而下降。2-氯乙基膦酸和苯并噻唑-2-氧乙酸都导致乙烯浓度增加,但它们对成熟的影响不同:前者在第二阶段开始时施用,后者在第二阶段结束前 1 周施用,可延迟成熟,而在第二阶段结束时施用 2-氯乙基膦酸则可加速成熟。随着浆果成熟,其脱落酸含量增加,2-氯乙基膦酸和苯并噻唑-2-氧乙酸对脱落酸水平的影响与这些化合物对成熟的影响相关。讨论了脱落酸和乙烯在葡萄成熟调控中的作用。
