摘 要 ：研究陕鲁和四川两地区5个小麦地方品种的光合速率对光强、温度和水分变化的反应。结果看出,北方陕鲁地区的小麦比南方四川的小麦光合的光饱和点高,适宜温度范围广。所有品种在水分亏缺下,光合速率都下降。当供水恢复时,北方小麦放出的 CO2比南方小麦多。这是由于北方小麦气孔关闭得早,CO2在体内积累得多。说明了北方小麦对干

Abstract:Using five local wheat varieties from southern and northern wheat regions,the investigation on response of photosynthetic rate to various light intensity,temperatureand water supply were carried out.The results showed that light saturatio pointsof photosynthcsis of northern wheat was highter,their o
