摘要
对限水条件下冬小麦的生长发育状况作了研究。结果表明：水分胁迫条件下植株生长受阻，绝对生长速率减慢，小麦生育后期绿叶面积迅速衰减，光合强度下降，早衰严重；研究发现，绿叶面积的稳定时间与灌水时间具有“临近效应”；穗下茎可作为土壤水分状况的良好指示性状。
The growth and development of winter wheat under controlling water were studied.The results showed that under stress of water growth of wheat was obstructed, absolute growth rate(AGR) and photosynthesis intensity declined. Green leaf area of plant decreased sharply after heading Period and premature senesence appeared under water deficit.'Near-effect' has found between duration of green leaf area and watering time.Under-spike internodal can be regarded as a reliable morphological indicator for soil water condition.
