摘要: 为探讨伤流量日变化与产量之间的关系,以及筛选抗旱节水品种。本研究对华北地区广泛种植的10个玉米品种日伤流量变化进行统计学分析,发现上午时的根系伤流量与产量呈显著正相关,特别是7:00-8:30的伤流量与产量有直接的线性关系,说明清晨时的伤流量可以作为一个直接的抗旱性指标。同时以上午时的伤流量和产量为指标可将供试品种分为四类,其中蠡玉18、冀玉9、郑单958、邢抗2、鲁玉13为伤流量较高的抗旱稳产性品种,浚单20为高伤流量的抗旱节水高产品种,这两类品种是较为理想的抗旱节水品种。

Abstract: In order to find the relationship between the root bleeding sap and yield,and select the drought-resistance high-yield varieties. This paper used 10 corn hybrids which widely cultivated in North China Plain. According to statistics analysis of the bleeding sap in a day, it is found that the bleeding sap in morning have positive correlation with the yield, the bleeding in 7: 00-8: 30 had direct liner relationship with the yield. It indicated that the root bleeding sap in early morning could be used as index for drought-resistance. The 10 corn hybrids could be classified in four clusters with the root bleeding sap and the yield. In that,Liyu 18, Jiyu 9,Zhengdan 958,Xingkang 2 and Luyu 13 was drought-resistance and stable-yield, Jundan 20 was drought-resistance and high-yield. These varieties could be planted in drought for stable and high yield.
