摘要: 为了探讨杂交小麦及其亲本杂交制种在喷施不同化控剂对株高和产量的影响,以杂交小麦‘新冬43 号’及其亲本材料为研究对象。选用多效唑(PP333)和矮壮素(CCC)2 种化控剂,在小麦起身期和拔节期分1 次和2 次叶面喷施,研究化控剂对小麦株高的矮化效应及产量的影响。结果表明:喷施矮壮素350 mg/L、多效唑400 mg/L 均能有效降低3 种材料的株高和节间长;多效唑不同剂量与产量为负相关。根据不同种植目的有针对性地选择不同的喷施方法,不仅降低株高提高小麦的抗倒伏性,还可以减少杂交小麦制种过程中亲本之间的株高差,有利于提高制种产量。

Abstract: The paper aims to explore the effect of spraying different chemical regulators on plant height and yield in hybrid wheat seed production. The authors took the hybrid wheat‘Xindong43’and its parents as the study materials, adopted 2 chemical regulators paclobutrazol (PP333) and chlormequat (CCC) for spraying 1 time and 2 times on foliar at wheat starting and jointing stage, to study the effect of chemical regulators on plant height dwarfing and yield. The results showed that: the plant height and internode length of the 3 materials could be effectively reduced by spraying 350 mg/L of chlormequat and 400 mg/L of paclobutrazol, and different doses of chlormequat were negatively correlated with yield. Choosing different spraying methods according to planting purposes can not only reduce the plant height to improve the lodging resistance of wheat, but also decrease the plant height difference between the parents in hybrid wheat seed production, and improve the yield of seed production.
