摘　　要：为了研究水分条件对不同基因型和抗旱性冬小麦生长发育和产量的影响,选用栽培二粒(原始小麦)、西农9871(敏感型现代小麦)和长武134(抗旱性现代小麦)进行了研究。结果发现:栽培二粒小麦分蘖和株高受水分的影响大,拔节期灌水对西农9871和长武134株高和分蘖没有显著影响,说明了原始品种生长发育受水分制约大于现代品种。栽培二粒小麦的产量在不同水分条件下没有显著变化,但西农9871和长武134不灌水处理的产量是充分灌水处理的50%,拔节期灌水并没有显著提高产量,说明了现代品种产量受水分影响大于原始品种。To study the effect of water conditions on growth and yield of different genotype and drought resistance winter wheat,In this paper,T.dicoccon Schuebl（original variety）,T.aestivum L Xinong9871（sensitive modern wheat）and T.aestivum L Changwu134（drought-resistant modern varieties） were used in the experiment.The results showed that： T.dicoccon Schuebl wheat tillering and plant height are more severely affected by water supply,the irrigation in jointing has no significant effect on tiller and plant height to T.aestivum L Xinong9871 and T.aestivum L Changwu134.It shows that： the growth and development of original varieties are more significantly restricted by water than modern varieties.T.dicoccon Schuebl yields in different water conditions have no significant variation,but yields of T.aestivum L Xinong9871 and T.aestivum L Changwu134 with no irrigation are half of that with sufficient water,however,irrigation in jointing did not significantly increase yield,which means that the modern varieties yield is more affected by water than the original varieties.
