冬小麦品种抗旱特征特性研究

对孕穗期６个类型２６个小麦品种的形态、生理研究表明，抗旱类型具有较高的株高，高的子粒产量，较高的生物学产量，高的穗粒数、成穗率，较庞大的耕层根系（０～５０ｃｍ），株型直立紧凑，叶片（尤其是旗叶）大而长，上半部下技或全披。在水分临界期，叶片具有较高的含水量。

Studies on Drought-resistant Feature and Specific Property of Winter Wheat Variety

This paper studies on form and Physiology of six types which consist of 26 wheat varieties during boot stage. The result shows that drought-resistant types have the features as follows: higher plant height, higher grain yield, higher biology yield, more grains in a tassel, high rate of forming tassel; massive topsoil roots (0￣ 50cm), straighten and tense plantly,big and long leaves (especially flag leaf),the top half of plant hanging down loosely.The leaves has high containing water during water critical period.
