纯品为白色结晶,工业品为白色粉末。能溶于醇、酮、酯类等有机溶剂,难溶于醚、氯仿、苯和水。与钾、钠离子形成盐并溶于水。赤霉素固体比较稳定。在干燥、密闭条件下贮存时间较久不会失效,水溶液不稳定。可在酸性或弱酸性条件及低温短期存放,温度较高或碱性条件时不稳定。
赤霉索可用发酵方法生产。利用赤霉菌在麸皮、蔗糖和无机盐等培养基中进行发酵,赤霉菌代谢产生赤霉素,发酵液经溶媒提取、浓缩即得。
高效植物生长调节剂。能促进作物生长发育,提早成熟,改进品质,提商产量。它能迅速打破种子、块茎和鳞茎等器官休眠,促进发芽,减少蕾、花、铃、果实的脱落,提高果实结实率或形成无籽果实。可用于水稻、麦类、棉花、果树、蔬菜等作物,促进其生长、发芽、开花、结果。赤霉素不论是喷雾、涂抹、蘸根,对不同作物都有增产作用,但施用过多的赤霉素,植物会出现黄而细长的枝条,即失绿、徒长现象,反而影响产量。赤霉素还可用于从大麦制造麦芽。它对昆虫的发育也有促进作用。
正常使用时对人畜无毒。小鼠急性经口LD50>25000mg/kg。大鼠吸入无作用剂量为250~400mg/L。无致畸、致突变作用。吞服有毒,粉末溅入眼睛要用大量水冲洗。
