摘要:
以水稻品种南粳45与玉米品种郑单958为试验材料,利用开顶式气室(OTCs)法研究二氧化碳(CO2)浓度升高处理下,水稻和玉米的叶片光合生理特性的变化,揭示CO2浓度升高对水稻和玉米生理特性的影响机理。结果表明:随着CO2浓度升高,水稻和玉米叶绿色度比值(soil and plant analyzer development,SPAD)呈现增加趋势。各处理间差异不显著(P>0.05)。水稻和玉米的净光合速率(net photosyntheic rate,Pn)和胞间CO2浓度(intercellular CO2 concentration,Ci)随着CO2浓度的增加而增加,但是水稻和玉米的气孔导度(conductance to H2O,Cs)和蒸腾速率(transpiration rate,Tr)随着CO2浓度的增加而降低。郑单958比南粳45更快达到CO2饱和点,出现光适应性现象。在较高CO2浓度下,C3作物的PnCiCsTr的影响幅度大于C4作物。
