摘要
利用灰色系统理论和方差分析对灌浆期3个品种的对生玉米与互生玉米的蒸腾速率和气孔导度日变化进行了比较研究,结果表明,对生玉米的蒸腾速率、气孔导度明显低于互生玉米;低的气孔导度可能是不同栽培品种玉米抗旱性强弱的指标之一。
Based on Grey system theory and square difference analysis, a comparative study of diurnal variations of transpiration rate and stomatal conductance was made on oppositifolious and alternative maize a-mong three species. The results showed that the transpiration rate and stomatal conductance of oppositifolious maize were lower than that of alternative maize.
