据苏联最近报道,在乌兹别克斯坦地区,农业科技人员用25mg/l(25ppm)浓度的赤霉素在开花后期对葡萄进行喷雾处理,10天后以此浓度再喷一次,可使早熟有核葡萄果实提早10～12天成熟,产量从17.04吨/公顷提高到19.01吨/公顷,增产幅度为11.56％。果实含糖量从13.3％提高到15.8％。这种处理在具有功能性开雌性花葡萄的栽培中更为显著,可增产31.9％。其增产主要是通过增加正常生长的浆果数量而获得的。葡萄果粒数量从每穗96粒增加到125粒,每穗葡萄重量从549.0g增加到775.8g,果实的含糖量也从16.9％增加到19.8％。
According to a recent report by the Soviet Union, in the Uzbekistan region, agricultural scientists and technologists sprayed grapes with gibberellic acid at a concentration of 25 mg / l (25 ppm) later in the flowering season. Spraying again at this concentration ten days later, Mature 10 to 12 days earlier, the output increased from 17.04 tons / hectare to 19.01 tons / hectare, with a yield increase of 11.56%. Fruit sugar increased from 13.3% to 15.8%. This treatment is more significant in the cultivation of functional female flowers, which can increase the yield by 31.9%. The increase is mainly achieved by increasing the number of berries growing normally. The number of grape berry increased from 96 grains per spike to 125 grains, the weight of grapes per spike increased from 549.0g to 775.8g, and the fruit sugar content increased from 16.9% to 19.8%.
