| 摘 要： | 对辽宁省推广的5个抗旱性不同的玉米品种进行了研究.通过室内发芽试验和室外盆栽试验,在总结前人成果的基础上,测定了与抗旱性有关的芽率、芽势和叶面积等16项鉴定指标.以种子萌发抗旱指数与幼苗反复干旱抗旱指数的乘积作为灰色关联度分析的参考数列,运用灰色关联度理论,分析各指标与苗期抗旱性的关系,从中筛选出关联度较大的10个指标,然后通过隶属函数法对这10项指标进行分析,定量地评价5个玉米品种苗期的抗旱。

| Abstract: | maize varieties with different drought-resistance were studied in Liaoning province. By measuring germination percentage,germination rate,leaf area and so on ,16 indices was researched in room and out .According to analytical result of gray relating degree, 10 drought-resistance indices were identified to estimate maize seedling drought-resistance character. By subject function method, every identified index was given a concrete value to quantificationally appraise maize seedling. |
