由于辣椒单果的种子数多,配制杂交种子利用化学杀雄剂时,杀雄剂的成本较低。现已明确,赤霉素(GA_3)对洋葱和莴苣有杀雄效果。本文报道了 GA_3对辣椒的杀雄效果。供试辣椒品种为加州奇迹。赤霉素溶液浓度为625、1250、2500、5000及10000ppm 五个浓度。在始花期喷第一次,隔10天再喷第二次,共喷二次,全株喷洒。5次重复。GA_3处理后,特别是10000和5000ppm 的处理,明显地延迟了花药发育,促进了花柱伸长。GA_3对于育性的影响,在10000ppm 处理中,全部为雄性不
Due to the high number of seeds in pepper single fruits, the cost of killing the maleicide is lower when formulating hybrid seeds using chemical killing agents. It is now clear that gibberellin (GA_3) has a killing effect on onions and lettuce. This article reports the killing effect of GA_3 on pepper. Pepper varieties tested for the miracle of California. Gibberellin solution concentration of 625,1250,2500,5000 and 10000ppm five concentrations. In the first flowering spray the first time, spray the second time every 10 days, a total of two spray, spray the whole plant. 5 repetitions. GA_3 treatment, especially 10000 and 5000ppm treatment, significantly delayed anther development and promoted the style elongation. The effect of GA_3 on fertility was not observed in males at 10,000 ppm
