诱导太谷核不育小麦孤雌生殖的研究初报

Preliminary Study on Induced Female Parthenogenesis in Taigu Genie Male-sterile Wheat

以太谷核不育小麦为试材,用化学药剂诱导其孤雌生殖.试验结果表明:氯苯氧乙酸、激动素、烟酸、肌醇、2,4-D、乙烯雌酚等化学药剂均有明显的诱导效果.不同施药方法,其诱导效果不同;注射法稍好于喷施,但喷施操作简便,更易于应用.不同剪颖深度对诱导效果的影响也明显不同,适当加深剪颖能提高诱导效果.本文从理论与实践的角度对应用大谷核不育小麦为诱导材料的可行性和优越性进行了论证.

The female parthenogenesis of Taigu genie male-sterile wheat was induced by tomatotone, kinetin, nicotinic acid, inositol, 2,4-D and so on. The induction effect was various in different method of application of the chemicals, and the injection method was a little better than spraying, but the spraying was easy to use. The different extent of glume-cutting also exerted obvious and different influence to the induction. A moderate extent of cutting would help raise the induction effect. The feasibility and advantage of Taigu genie male-sterile wheat taken as experimental material of induced pathenogenesis was demonstrated in this papr.
