摘要
以6个玉米品种为试验材料,苗期进行水分反复干旱试验,对株高、干物质、根干重和存活率等相关参数进行灰色关联度分析。结果表明:失水率、株高胁迫指数、根干重胁迫指数均能很好地反映出玉米苗期的抗旱性,是苗期抗旱性评价的重要形态指标。
Using six varieties of maize as materials, the paper had done repeated drought stress and normal water experament tlunng seeamg stage. Some related parameters such as dry matter,plant height, root d~ weight and survival rate were analyzed by grey correlative.The results showed that the water loss rate, plant height damage index, root dry weight damage index reflected the anti-drought trait of maize in seeding stage quite well which were important morphological traits for anti-dronght evaluation of seeding.
