【摘要】 利用盆栽洗根法对玉米根系各参数进行了系统研究。结果表明 ,不同基因型玉米在形态、解剖及生理活性上的差异是形成其抗旱性不同的原因之一 ;根系参数与玉米抗旱性的关系密切 ,在抗旱性鉴定时应加强使用。更多还原

【Abstract】 The parameters of maize roots system were studied systemically in a pot experiment by the method of washing roots.The experimental results showed that the differences among the morphological,anatomical and physiological activity resulted in the differences in drought resistance in maize.The relationship between roots system and drought resistance was closely related,which should be used in drought resistance identification.更多还原
