Two strains of spring wheat (Triticum aestivum L-high productive Gaoyuan 602 and drought-tolerating Dingxi 24) were grown at two different CO2 concentrations (350 and 700 μmol·mol-1) and three soil water levels (80%, 60%, 40%FWC) in open-top-chambers from sowing until final harvest.
为考察春小麦不同抗旱性品种对干旱和高CO2反应的差异,在不同土壤持水量和CO2浓度梯 度条件下,对高产性高原602和抗旱性定西24两种春小麦交叉处理一个生长季,结果发现CO2浓度倍 增,使两种春小麦的光合速率、气孔阻力和水分蒸腾效率显著增加,增加幅度与土壤含水量分别为正、 负和正相关。
