Comparative Studies on Biochemical Components in Mung Bean [Vigna radiata (L.) Wilczek] Varieties Cultivated in Summer and Kharif Seasons

摘要

Biochemical components in two mung bean varieties (SML 668 and ML 1333) cultivated during summer and kharif seasons were compared. The biochemical constituents in mature seed coat, cotyledons and changes during seed development were evaluated. Seed coat constituents viz; cellulose, hemicellulose, lignin and phenols responsible for hardseededness were higher in ML 1333 than SML 668, and in both varieties sown during Kharif than in summer season, whereas the contents of seed cotyledonary biomolecules viz; proteins, total sugars, starch and lipids were lower in kharif than summer season affecting grain quality of seed. Crude protein, soluble protein, sulfur containing amino acids, albumins and storage protein-globulins were higher in developing seeds in both varieties sown in summer than kharif season showing seasonal effect on seed protein quality. Within varieties, these parameters were higher in SML668 than ML1333.
