关于在植物发育的早期阶段来预测其早熟性的问题,很早以来就引起果树选种家的注意。学者们除了研究植物的早熟性与外部形态相关的性状外,还在力求寻找与各植物的早熟性和晚熟性有密切联系的生理生化因素。在葡萄方面研究得较多的是早熟性与氧化酶的关系,但所得资料互为矛盾,没有取得一致的看法。 The question of predicting its precocity in the early stages of plant development has long aroused the attention of fruit tree breeders. In addition to studying the early maturity of plants and external morphology-related traits, scholars are still seeking to find the physiological and biochemical factors closely related to the plant’s early maturity and late maturity. Studies on grapes are more about the relationship between precociousness and oxidase, but the data obtained contradict each other, and no consensus has been reached.
