摘要：

为揭示生长促控剂PBOG对大豆产量及其相关性状的影响，探究其适宜的施用浓度，选用亚有限结荚习性大豆品种‘垦丰16’为材料，在大豆初花期使用不同浓度梯度PBOG(0、0.5、1、2、3 g/L)进行叶面喷施，探究PBOG对大豆株高、主茎节数、底荚高度、有效荚数、单株粒数、百粒重、产量等性状的影响。结果表明，在PBOG浓度为3 g/L时，株高与底荚高度降幅最大且差异显著，两者分别下降了41.9%、44.1%；而百粒重在此浓度下达到最大值19.05 g，增加13.3%；PBOG浓度为1 g/L时，主茎节数、有效荚数、单株粒数显著增加；产量随着PBOG浓度增加表现出先上升后下降的趋势，在浓度为1 g/L时最大，涨幅21.6%，而后逐渐降低，在3 g/L时低于对照组。综上，对于亚有限结荚习性品种‘垦丰16’，PBOG最适施用浓度为1 g/L，此浓度下增产幅度达21.6%，且提高了植株的抗倒伏能力。

Abstract:

In order to reveal the effect of PBOG on yield and yield-related traits of soybean, and to investigate its suitable application concentration, we chose the sub-limited podding habits soybean variety ‘Kenfeng 16’ as the material, and conducted foliar spray with five different concentration gradients of PBOG: 0, 0.5, 1, 2 and 3 g/L at the early flowering stage of soybean. The effects of PBOG on soybean plant height, node number of main stem, bottom pod height, number of effective pods, kernel number per plant, 100-kernel weight and yield were investigated. The results showed that the plant height and bottom pod height decreased the most and significantly at PBOG concentration of 3 g/L, with a decrease of 41.9% and 44.1%, respectively; while 100-kernel weight reached the maximum of 19.05 g at this concentration, with an increase of 13.3%. The node number of main stem, number of effective pods, and kernel number per plant increased significantly at PBOG concentration of 1 g/L. The yield showed a trend of first increase and then decrease with the increase of PBOG concentration, with the maximum increase of 21.6% at the concentration of 1 g/L, and then gradually decreased, and was lower than that of control at 3 g/L. In conclusion, the optimum application concentration of PBOG is 1 g/L for the sub-limited podding habits variety ‘Kenfeng 16’, the yield can be increased by 21.6% at this concentration, and the lower plant height can improve the lodging resistance.
