摘要:
采用大田试验,于开花后 1~11 d分别设置遮光、渍水、遮光+渍水复合胁迫3种逆境处理,研究了花后遮光渍水逆境对南京冬小麦光合特性及产量的影响。结果表明:遮光、渍水、遮光+渍水3种逆境处理都导致冬小麦开花后旗叶光合速率(Pn)、蒸腾速率(Tr)、气孔导度(Gs)和胞间CO2浓度(Ci)下降,穗粒数以及粒质量降低,产量减少,其中遮光+渍水复合逆境对冬小麦产量的影响最大,遮光逆境次之,渍水逆境对冬小麦产量的影响最小。
Abstract:
The individual and combined effects of shading and waterlogging on photosynthetic characteristics and grain yield of winter wheat were investigated at 1-11 d after anthesis. All three stress treatments reduced net photosynthetic rate (Pn), stomatal conductance (Gs), transpiration (Tr), and intercellular CO2 concentration (Ci) of flag leaf, decreased grain number and grain weight, thereby lowering the yield of winter wheat. Combined imposition of shading and waterlogging caused the biggest drop in winter wheat yield, while solo waterlogging stress exhibited the smallest.
