为了提高盆花的商品价值,必须确保盆花在上市出售时的花朵数量。赤霉素是一种众所周知的开花促进剂。但是,赤霉素的作用只不过是缩短开花期。如果在开花初期从植物体内抽出的花茎数目少,即使用赤霉素处理了,也不过是促进了这些花茎的生长,缩短了开花期而已。 In order to increase the commodity value of potted flowers, it is necessary to ensure that the potted flowers are on sale at the time of sale. Gibberellin is a well-known flowering enhancer. However, the role of gibberellin is only to shorten the flowering stage. If the number of flowering stems withdrawn from the plant in the early flowering stage is small, the treatment with gibberellin will only promote the growth of these flowering stems and shorten the flowering period.
