现在世界上约有１／３的耕地处于供水不足状态，许多试验也已证明由于水分胁迫导致的减产超过其它因素造成减产的总和。玉米在粮食作物中占的比重越来越大，有关抗旱生理的研究工作日益受到人们的重视。本试验结合抗旱生理育种，筛选抗旱的自交系及种群，对玉米植株叶片在抽丝?
About one-third of the world’s cultivated land is now in undersupplied water and many tests have also shown that the reduction in production due to water stress outweighs the total reduction in production. The proportion of maize in food crops is more and more large, and the research on drought resistance physiology has been paid more and more attention by people. This experiment combined with drought-resistant physiological breeding, screening of drought-resistant inbred lines and populations of corn plant leaves in the spinning?
