SYNTHETIC DETERGENT INDUCED CHANGES IN THE SEED IMBIBITION PATTERN AND DEHYDROGENASE ACTIVITY IN MUNGBEAN VIGNA RADIATA)

Nand Lal and Richa Mishra

Abstract

Mungbean (Vigna radiata) seeds failed to germinate above 0.1 % (w/v) detergent (Surf Excel) leveI.The water imbibition in seeds was accelerated by 0.025% detergent over control whereas other detergent concentrations retarded it. Detergent at 0.25% level extended the duration of log linear phase of imbibition by 4 hours.The relative imbibition rate was accelerated by 0.025% detergent at peak # I whereas at peak #2, accelerated was noted with 0.025 and 0.05% ievels.The dehydrogenase activity showed reduction with increase in detergent concentration and was significantly lower at 0.15% and above levels leading to failure of germination.
