不同类型玉米苗期抗旱性探讨
|
| |
摘要：用相对发芽率、根系干重、叶片含水量等农艺性状指标对9个类型及18个玉米品种苗期抗旱性进行了初步探讨,用模糊隶属法对其抗旱性做了综合评价,以平均抗旱隶属值对品种抗旱性强弱进行了排序。结果表明：半马齿型抗旱性最强；其次为爆裂型、高蛋白型、马齿型；再次为硬粒型、糯质型、软粒型、甜质型、高油型。
关键词：玉米 抗旱性 模式干旱胁迫 模糊隶属法
Abstract: A studies of the drought-resistant identification on nine types(18 maize varieties) in condition of simulated drought stress were tested though 3 agronomical indexes such as relative germination frequency, root dry weight, leaf water content, the subordinate Fuzzy function was used to evaluate compressively the drought resistance of the eighteen maize varieties. Based on the average subordinative value, the drought resistance of different cultivars of maize was arranged. The result showed that the half-horse type have the highest drought resistance; and the second is pop 、high protein 、horse type; and the hard 、sticky 、soft、sweet、high oil type possessed of small drought resistance
