钼对黄棕壤上冬小麦碳代谢的影响

盆栽试验条件下,研究了钼对冬小麦碳代谢的影响。结果表明,缺钼使冬小麦植株功能叶片叶绿素含量自分蘖期开始明显下降,随后各生育期均表现为黄化;植株可溶性总糖和纤维素、半纤维素含量也因缺钼而下降,这可能是缺钼冬小麦叶片疲软、抗寒能力下降的重要原因。

The Mechanism of Molybdenum Effects on Carbon Metablism of Winter Wheat in Acid Yellow Brown Earth

Pot culture experiment was conducted to study the effects of molybdenum on carbon metablism of winter wheat. The main results are as the follows: molybdenum deficiency retarded the growth of winter wheat and reduced chlorophyll content remarkably in functional leaves.As a result,the content of assimilation products decreased ,molybdenum deficiency retared the synthesis of cell wall constituents including cellulose , hemicellulose etc., which caused downward curling of leaves.;
