摘　　要：采用大蒜低温反应中间型的 3个品种 ,研究了种蒜温度处理对大蒜生长发育、耐寒性及病毒病发病状况的影响。结果表明 ,种蒜的低温处理促进了鳞芽分化 ,但抑制了生长 ;而高温处理虽使鳞芽分化较晚 ,但促进了生长。随着种蒜处理温度的升高 ,叶片相对含水量和自由水含量减少 ,束缚水含量增加 ,植株的抗寒性增强 ,病毒病发生程度减轻。Using 3 garlic cultivars of low temperature middle type,the physiological effects of seed clove treatment at different temperatures before planting were studied.The results showed that the lower treatment temperature promoted the differentiation of scaly bud,but inhibited the plant growth,and the higher treatment temperature did on the contrary.As the treatment temperature raised,the relative water content and free water content of leaves decreased,the bound water content of leaves increased,the cold tolerance of plants was improved and the virus disease index of plants decreased.
