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。 The effects of garlic temperature treatment on the growth and development of garlic, cold tolerance and the incidence of virus diseases were studied by using three varieties of low temperature intermediate garlic. The results showed that the low temperature treatment of garlic promoted the differentiation of scale buds, but inhibited the growth; while the high temperature treatment led to the late differentiation of scale buds, but promoted the growth. With the increase of treatment temperature, the relative water content and the free water content of the leaves decreased, the bound water content increased, the cold resistance of the plants increased, and the degree of virus disease decreased.
