Abstract: | 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. |
