一、引言赤霉素是一种新的植物生长刺激剂,它具有促进植物生长、打破休眠、促进开花、单性结实等作用。近几年来许多国家大规模地进行有关赤霉素对植物生长和发育的研究。1958年以来,在我国农业界和生物界也引起普遍重视,各地都进行试制和应用,并取得了一定的成绩。试验证明:赤霉素对许多经济作物和蔬菜作物有显著的效果。在田间生产条件下,赤霍素对芹菜、黄花苜蓿、茼蒿等绿叶蔬菜有促进生长、提高产量、改进品質的效果。在农业生产上有广泛应用的前途。本文是赤霉素在蔬菜作物上应用的初步结果。
I. Introduction Gibberellin is a new plant growth stimulant, which has the effect of promoting plant growth, breaking dormancy, promoting flowering and unisexual fruiting. In recent years, many countries have conducted large-scale studies on the effects of gibberellin on plant growth and development. Since 1958, widespread attention has also been paid to the agricultural and biological communities in our country, all of them have been trial-produced and applied, and certain achievements have been made. Experiments show that: GA has a significant effect on many cash crops and vegetable crops. Under the field production conditions, the effect of the thio-hormone on green leafy vegetables such as celery, alfalfa and chrysanthemum can promote growth, increase yield and improve quality. In the agricultural production has a wide range of applications. This article is the initial result of application of gibberellin in vegetable crops.
