摘　　要：木豆(Cajanus cajan)是一种药食兼用型的豆科植物,为了探究木豆不同种质资源在不同采收期营养成分动态变化。本试验选取8个采样时间,测定并比较其营养成分含量(干物质,粗蛋白,总黄酮等),根据营养成分的综合比较,以期确定木豆最佳采收时期。研究结果表明:随着采收期的延长,不同木豆种质的干物质(DM)、粗蛋白(CP)、总黄酮(GF)含量先升高后下降;中性洗涤纤维(NDF)、酸性洗涤纤维(ADF)含量均逐渐升高后达到平稳,可溶性糖(SS)和水溶性浸出物(WSE)含量先降低后升高;粗蛋白与总黄酮呈现显著正相关(P<0.05)。木豆初花期时粗蛋白、干物质含量均处于峰值,且总黄酮含量显著高于其他大部分时期(P<0.05),其中9-HK2的总黄酮、粗蛋白等方面综合表现较佳。本研究结果可为木豆种质选育、杂交育种以及最佳栽培模式提供理论依据。Pigeonpea(Cajanus cajan) is a kind of leguminous plant that can be used as both medicine and food.In order to explore the dynamic changes of nutrient components of different germplasm resources pigeonpea in different harvesting periods.In this experiment,we selected 8 sampling times to measure and compare the nutrient content(dry matter,crude protein,general flavone,etc.) of pigeonpea,and finally to determine the best harvesting period.The results showed that the contents of dry matter(DM),crude protein(CP) and general flavone(GF) were the highest in the initial flowering stage and then decreased.The contents of neutral detergent fiber(NDF) and acid detergent fiber(ADF) increased gradually and then reached a stable level,while the contents of soluble sugar(SS)and water-soluble extract(WSE) decreased first and then increased.There was a significant positive correlation between crude protein and general flavone(P<0.05).The crude protein and dry matter contents were the highest at the initial flowering,and the content of general flavone was significantly higher than many other periods(P<0.05).The contents of crude protein and dry matter of pigeonpea were at the peak in initial flowering,and the content of general flavone was significantly higher than most other periods(P<0.05),the general flavone and crude protein of9-HK2 showed better performance.The results of this study can provided a theoretical basis for germplasm selection,cross breeding and the best cultivation pattern of pigeonpea.
