扁豆中黄酮的积累规律研究

Research on the Accumulation Law of Flavonoids in Lentils

[目的]探讨扁豆中黄酮的积累规律。[方法]测定了23个扁豆资源不同发育时期[结荚鼓粒初期(Ⅰ)、结荚鼓粒中期(Ⅱ)、结荚鼓粒末期(Ⅲ)]扁豆豆粒、荚皮、豆荚3个部位的黄酮含量。[结果]扁豆不同部位黄酮含量在各时期均差异显著,不同时期在豆粒、荚皮、豆荚中黄酮平均含量从高到低依次为Ⅰ、Ⅱ、Ⅲ。各期都以幼嫩豆荚中黄酮含量最高;黄酮含量以13号扁豆资源的表现最优。[结论]研究结果可为扁豆的选种育种提供理论依据。

[Objective]To discuss the accumulation law of flavonoids in lentils.[Method]The content of flavonoids in pea,pod and pod wall of 23 lentil resources in three developmental stages, including early podding stage （Ⅰ）, middle podding stage （Ⅱ） and late podding stage （Ⅲ） were determined.[Result]The content of flavonoids in different parts of lentil had significant differences among three development stages.The average content order of flavonoids in pea,pod wall, pod in three development stages was Ⅰ〉Ⅱ〉Ⅲ.The content of flavonoids in tender pod in each development stage was the highest.The content of flavonoids in lentil resource No.13 was the highest.[Conclusion]The research results can provide theoretical basis for the selection and breeding of lentils.
