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。
The gray system theory and analysis of variance were used to study the diurnal variation of transpiration rate and stomatal conductance of three varieties of maize and maize during the filling stage. The results showed that transpiration rate and stomatal conductance of maize were significantly lower than Alternant corn; low stomatal conductance may be one of the indicators of drought resistance in different cultivars.
