低温对缺钼冬小麦幼苗生长的影响
Effect of molybdenum on growth of winter wheat seedlings induced by low temperature<br> II. Effect on nitrogen metabolism
摘要
Abstract
Low temperature ( LT,-5~0℃) has been underway for 24h when winterwheat seedlings are 28 days old. The results as followed : Mo deficiency has no obvious effects on N content of whole plant but affects distributi on of it significantly. Under normal temperature (NT) conditions, N content in shoot of Mo applied decreases significantly, while that in root increases obviously,and N content in root has no distinct difference between Mo deficiency and Mo application under LT condition. Soluble protein contents in shoot and root have no relation with Mo and LT. Under NT conditions, free amino acid content of shoot is enhanced obviously by Mo;after induced by LT, that of both shoot and root increase significantly, especially shoot. Nitrate reductase activity of Mo applied keeps at a relative high level under LT conditions.关键词
