大豆叶片希尔反应活性与酰脲的关系

THE CORRELATION BETWEEN HILL REACTION ACTIVITIES OF SOYBEAN LEAVES AND UREIDE CONTENTS

摘要:

大豆叶片希尔反应活性稚幼茎段酰脲含量在鼓粒期都有一高峰。叶片希尔反应活性与幼茎段酰脲含量在开花期呈极显著正相关。表明, 大豆生殖生长时期叶片的光合活性与根系共生固氮体系的固氮作用存在着密切关系。

Abstract:

Hill reaction activities in soybean leaves and ureide (allantoin and allantoic acid) contents in young stems all showed a high peak during podfilling stages. A significantly positive correlation between Hill reaction activities and ureide contents in young stems was observed. The results showed that there was close correlation between leaf photosyn thetic properties and symbiotic nitrogen fixation at reproductive stages.
