赤霉素对某些植物生长的效应与温度的关系,在前一报告中(罗士韦与黄文徽,1960)已提及,指出赤霍素作用的有效延续时间,在较低温度条件下为长,但是效应高峰出现的时间,则在较高温度条件下提早。据 Wittwer 和 Bukovac(1958)报告,赤霉素能适当的延长植物的生长季节,即在早春提早与晚秋延迟。Щепотьев等(1961)的实验,指出一种栎树(Quercus robur L.)受赤霉素的作用在林地及盆栽条件下均降低了植物的抗寒性。
The effect of gibberellin on the growth of certain plants and their relationship to temperature has been mentioned in the previous report (Roswell and Huang and Huang, 1960), indicating that the effective duration of the action of the Cholow, at lower temperatures, is Long, but the effect of the peak time, then at higher temperatures earlier. According to reports from Wittwer and Bukovac (1958), gibberellin can appropriately prolong the plant’s growing season, ie early and late fall in early spring. Experiments by Щепотьев et al. (1961) showed that the oak tree (Quercus robur L.) is gibberellin-resistant and reduces plant cold resistance both in woodlands and potted plants.
