不同水分处理对不同玉米品种株高和叶面积增长速度的差异分析

Variance Analysis of Different Water Treatments on Plant Height and Leaf Area Growth of Different Maize Varieties

为了确定玉米耐旱评价指标,以黑龙江省农业科学院玉米研究所高产室选育的相对耐旱玉米新品种龙单23和相对不耐旱的龙343为试验材料,研究不同水分处理条件下玉米株高及单株叶面积增长速度差异,对应分析和比较不同类型玉米品种的生长状况。结果表明:水分胁迫对龙343株高及单株叶面积的影响要大于对龙单23的影响。

In order to determine the evaluation index of maize drought tolerance,taking drought-tolerant maize variety Longdan 23 and relatively drought-sensitive Long 343 as test materials,in different water treatment under the condition,growth difference of maize plant height and leaf area per plant was researched,under the condition of different water restriction,growth status difference of different types of maize varieties were analyzed and compared.The results showed that water stress had the large impact on Long 343 plant height and leaf area per plant than on the Longdan 23.
