Merr. vars. Ajigen and Huuki) stored at 5°C for 10 days. Percent weight loss of the pods decreased with few fluctuations until the end of the experimental period. The degree of yellowing gradually increased with time. Respiration rate rapidly declined in both cultivars after 2 days of storage. The acid invertase activity of soluble and cell wall-bound fractions increased with some fluctuations throughout the storage period in both cultivars. During storage, acid invertase activity of cell wall-bound fraction showed higher activity than that of soluble fraction. There was a significant negative correlation between invertase activity (soluble and cell wall-bound fractions) and soluble sugars (sucrose, fructose and glucose). Among the three sugars, sucrose constitute the highest concentration. Glucose was present but in smaller amount than that of sucrose and fructose. Comparing the two cultivars, Huuki showed higher percentage of weight loss, degree of yellowing, enzyme activities and sucrose content than Ajigen.]]>Jain, Y.,1995176772Weber, C.R.,19561013141314Masuda, R., K.
