摘要：

For out-of-season strawberry production, plant growth regulators (PGRs) were used to promote flowering of short-day June-bearing cultivars. During the period of flower inhibition after chilling, application of a gibberellic acid (GA) biosynthesis inhibitor, prohexadione calcium (PCa), reduced petiole length but did not enhance flower induction. Two-month-old runner plants in a flower inductive condition, treated with PCa, did not promote flower induction; benzyladenine delayed flowering and GA(3) completely inhibited flowering. When GA(1) was applied to shoot tips when plants were transferred from a flower inductive condition into a glasshouse in summer, flowering was inhibited. With sufficient duration of flower induction treatment, GA, administered at any time did not promote flowering in this study.
