摘要： 以谷子为材料，在盆栽条件下研究了前期干旱锻炼对谷子水分利用效率的影响。实验结果表明，不论苗期还是拔节期的干旱锻炼，都使其生育后期的水分利用效率显著提高，水分利用效率提高的原因并不是由于耗水绝对量的减少，而是干旱锻炼改善了叶片的同化功能，使同化能力的增长超过了蒸腾的增加。从叶片净光合速率、叶绿素含量、

Abstract: The effects of drought hardening in earlier growing stage on water utilization efficiency (WUE) of Millet was studied. Experiment results showed that, drought hardening in seedling or jointing stage could remarkably improve WUE in late stage, the reason for such increasing not being due to the reduc
