赤霉素是真菌(主要是水稻恶苗菌)的代謝产物,近年来許多高等植物中也有发現。赤霉素能加速植物的生长和发育,它比人工合成的植物生长刺激素如2,4-D、萘乙酸等的活化性能要高得多,在对植物作用上也有很大的不同,因而近年来国内外对赤霉素的研究日益增多。 溫州市生物化工厂从1959年1月就开始生产赤霉素。同年3月,温州市农科所、西山生产队,梧埏公社农埸相继进行赤霉素对蔬菜、花卉、香料作物生长的研究,获得显著效果。1960年温州地区各地农业試驗研究单位和不少生产队都广泛試驗和施用,共施用赤霉素液11吨(每公斤浸出液含赤霉素200-300ppm)施用面积估計为4千多亩,受試作物有稻、麦、玉米、大豆、高粱、薯类、蔬菜、花卉、香料作物、
Gibberellin is a metabolite of fungi (mainly rice seedlings), and has also been found in many higher plants in recent years. Gibberellins can accelerate the growth and development of plants. They are much more active than synthetic auxins such as 2,4-D, naphthaleneacetic acid and so on. They also have very different effects on plants and therefore In recent years, the research on gibberellin has been increasing. Wenzhou biological chemical plant from January 1959 began producing gibberellin. In March of the same year, the research of gibberellin on the growth of vegetables, flowers and spices crops was conducted by Wenzhou Agricultural Science Institute, Xishan Production Team and Wutong Commune. In 1960, various agricultural research institutes and many production teams in Wenzhou were extensively experimented and applied a total of 11 tons of gibberellic acid (200-300ppm of gibberellin per kilogram of leachate). The application area was estimated to be 4,000 mu Trial crop rice, wheat, corn, soybeans, sorghum, potatoes, vegetables, flowers, spices crops,
