黄瓜雌性系作为品种栽培或用于杂种一代制种,都以它早熟、果数多和结果集中等优点而得到人们的日益重视。但其雌性系内的雌性株因本身不形成雄花,而使雌性系的繁殖受到很大的限制。目前国内唯一用于雌性系诱雄的赤霉酸类型是上海生产的精制“九二○”。但这种“九二○”诱雄剂从我们近几年的使用效果看,并不理想。经“九二○”诱导的植株,雄花诱发数量少,雄花出现晚,着生节位高。上述现象都不利于诱导株 Cucumber female lines as cultivars or for the hybrid generation of seed production, all with its premature, fruit number and result of concentration and other advantages and get more attention. However, the females within the females do not form male flowers because of their own, leaving females breeding is greatly limited. At present, the only type of gibberellic acid used in luring females is the refined “920” produced in Shanghai. However, this “nine two ○” lure from the effect of our use in recent years, the view is not satisfactory. After “920” induced plants, male flowers induced a small number of male flowers appeared late, with birth position high. The above phenomenon is not conducive to the induced strain
