鼓粒期间不同品质类型大豆植株酰脲含量变化规律研究
Change of Ureides Content in Different Quantily Soybeans During Seed Filling Period
摘要
Abstract
Ureides is the product in nitrogen fixation,nitrogenase is the main form of nitrogen transformation from roots to shoots in soybean.Soybean was cultivated with sand culture method,and high-oil soybean variety Dongnong 47 and high-protein soybean variety Dongnong 48 were used as experimental materials to study the change law of ureides content in soybean plant during the seed filling period.The result showed that ureides content in different organs showed grossly a downward trend during the seed filling period.The size order of ureides content in different organs was stem ＞ pod ＞ root ＞ leaf.Change trend of ratio between allantoic cid and allantoin were different among different organs.There were significant positive correlation between ureides content and nitrogen content in stem for both varieties,and positive correlation between ureides content and nitrogen content in leaf for Dongnong 48,and no correlation between ureides content and nitrogen content in other organs.Higher ureides content and lower nitrogen content in leaf was found for high-protein soybean variety Dongnong 48,and it was opposite to high-oil soybean variety Dongnong 47.关键词
