花后DA-6处理对玉米自交系郑58种子活力的影响
|
摘要
DA-6作为一种高效植物生长物质,对多种农作物具有显著的增产、抗逆、抗病、改善品质、早熟等功效,但有关其对种子活力的影响研究少。以玉米自交系郑58为试验材料,将6g/L DA-6分别于花后0、5、15、25、35d均匀喷施于玉米叶片,研究DA-6对玉米种子活力的影响。结果表明,不同时期喷施DA-6可不同程度增加种子内蛋白质含量,进而影响种子活力。不同时期喷施DA-6使得种子活力与对照存在显著性差异,且随着处理时间延后种子活力逐渐升高。在花后35d处理,其种子活力指数达最大值,为0.77,较对照增加0.10,提高14.8%。因此,在玉米自交系郑58花后35d喷施DA-6可有效提高玉米种子活力。
As an efficient plant growth regulator, DA-6 had significant effects on crop yield-increasing, stress-resistance, disease-resistance, quality-improving, and early-maturity, however the research about their effect on seedvigor was limited. In this study, a maize inbred line Zheng 58 was used as a test material. 6 g/L DA-6 was uniformlysprayed on plant leaves at 0, 5, 15, 25, and 35 days after anthesis(DAS) to study its effects on plant seed vigor. Theresults showed that spraying DA-6 at different growth stages could increase the protein content of seeds to differentlevels, and subsequence affect the seed vigor. By comparing to CK, the effect on seed vigor by spraying of DA-6 gradually increased with the postponing of treatment time. The treatment at 35 DAS, the seed vigor index reached amaximum value of 0.77, which was 0.10 higher than that of CK. Therefore, the spraying of DA-6 on maize inbred lineZheng 58 at 35 DAS could increase the seed vigor of maize effectively.
