摘 要 ：在小麦灌浆期，剧烈的气温变化会导致一些品种和麦田发生发青枯危害，表现为茎杆青灰发暗，不能正常落黄；籽粒灌浆不足，千粒重大幅度下降，造成减产。品种间对此反应不一，受害程度大小不同。研究表明，抗青枯品种具有较强的根系活力，体内可溶性总糖量高，而总氮量低，花后灌浆期，茎鞘叶物质分解转运量大，转运速率高，植

Abstract:The dramatically changed temperature at grain filling often caused dying green of plants in some wheat varieties, which symptomatized dark-glaucous stems, unusual yellow ripening and unfully filling grains, and finally resulted in a substantially decreased grain weight and yield. Simultaneously othe
