摘要: 为了提高油菜(Brassica napus L.)种子活力以增强种子萌发和幼苗阶段的抗逆性,试验通过响应面分析方法对不同微量元素组合间效应进行比较分析,得出对油菜种子活力提升效果最佳的元素组合,并进一步验证了该组合对不同油菜品种生长发育和最终产量的影响。结果表明,Se(5.0 mg/L)、B(5.0 mg/L)、Zn(100.0 mg/L)、Mo(1.0 mg/L)对油菜种子萌发均具有明显的促进作用;响应面分析得出最佳微量元素配比组合为Se(6.7 mg/L)+B(7.5 mg/L)+Zn(82.3 mg/L)+Mo(4.6 mg/L),在此配比组合处理下,幼苗期可溶性蛋白质的累积量提高且幼苗的抗逆性也有明显增强;不同品种中的应用试验证明该配比组合处理可显著提高其单株产量(P<0.05)。

Abstract: In order to improve the seed vigor of rape (Brassica napus L.) to enhance the stress resistance during seed germination and seedling stage, the effects of different trace element combinations were compared and analyzed by response surface analysis method to derive the element combination with the best effect on rape seed vigor improvement, and the influence of this combination on the growth, development and final yield of different rapeseed varieties was further verified. The results showed that Se (5.0 mg/L), B(5.0 mg/L), Zn(100.0 mg/L) and Mo (1.0 mg/L) had significant effects on seed germination. Response surface analysis showed that the optimal combination of trace elements was Se (6.7 mg/L)+B (7.5 mg/L)+Zn (82.3 mg/L)+Mo (4.6 mg/L). Under this combination, the accumulation of soluble protein was significantly improved, and the stress resistance of seedlings was also significantly enhanced. The application experiments in different rape varieties proved that this combination could effectively increase the yield per plant (P<0.05).
