Biochemical basis of resistance to stored grain pests in rice bean (Vigna umbellata)

摘要

Extraction and assay of proportion to-amylase inhibitor, trypsin inhibitor and chlorogenic acid content of rice bean and mung bean seed meal showed significant differences. All the three parameters seem to be positively correlated with resistance offered to storage grain pests. The In vitro proportion to-amylase inhibitor potential of rice bean when tested against porcine pancreatic proportion to-amylase was almost twice as that of mung bean. Trypsin inhibitory potential and chiorogenic acid contentwas also significantly higher in rice bean which is least attacked by stored grain pests.
