摘要
为了提高黄瓜杂交制种种子产量,结合植物生长调节剂在蔬菜上的应用实践,研究了乙烯利和氯吡脲对黄瓜杂交制种种子产量和质量的影响。结果表明,150~250mg·L^-1乙烯利于母本4叶1心时喷施效果较佳,种子产量提高了45.8%;3~6 mg·L^-1氯吡脲于授粉后浸蘸瓜,效果较佳,产量增加30.0%,化瓜率由对照的34.1%降低到8.0%。乙烯利和氯吡脲的研究应用可为黄瓜制种实践提供技术支撑。
In order to improve the production of cucumber hybrid seed, the effects of ethephon and chlorpyrifos on cucumber hybrid seed production were studied. The results showed that spraying 150-250 mg·L^-1 ethylene at 4 true leaf period worked best, and the seed yield increased by 45.8%. When the pollinated cucumber was dipped in 3-6 mg·L^-1 chlorpyrifos, the yield increased by 30.0%, and the undeveloped cucumber rate decreased from 34.1% to 8.0% compared with control. It could provide technical support for cucumber seed production in practice.
