播期对吉林省不同类型花生(Arachis hypogaea)生理性状及产量的影响

Effects of Sowing Date on Physiological Traits and Yields of Different Types of Peanuts(Arachis hypogaea) in Jilin Province

本研究以吉花3号、吉花4号、吉花19号为供试材料,设置5月5日、5月10日、5月15日、5月20日、5月25日等五个播期。研究播期对不同类型花生生理性状及产量的影响。结果表明:播期对花生叶片保护酶的活性有显著影响,但其影响没有明显规律性;播期对丙二醛含量有显著影响,在播后90 d及105 d,5月20日和5月25日两个播期的丙二醛含量显著高于其它播期,不利于花生的荚果及产量的形成;三种类型花生都是5月5日播期的产量最高,而5月25日的播期的产量最低。本试验通过对不同播期的花生植株性状及最终产量的测量,为吉林省花生播种的最佳时期在理论上提供参考。

In this research we took Jihua No.3, Jihua No.4 and Jihua No.19 as experimental materials and set up five sowing dates on May 5, May 10, May 15, May 20, May 25, respectively, which to study the effects of sowing date on physiological traits and yields of different peanut varieties. The results showed that there was a significant effect of the sowing date on the activities of protective enzymes in peanut leaves, but it had not obviously regularity. Also there was a significant effect of sowing date on the contents of Malondialdehyde. After sowing for90 d and 105 d, the contents of Malondialdehyde on two sowing dates of May 20 and May 25 were significantly higher than other sowing dates, it was not conducive to the formation of peanut pods and productions. These three types of peanuts had the highest yield of May 5 and the the lowest yield of May 25. This research measured the traits and the final output of peanuts in different sowing dates, that provided a theory reference for peanuts sowing in the best period of Jilin Province.
