Abstract:
Seeds of
mung bean (Vigna radiata (L.) Wilczek and groundnut (Arachis
hypogaea L.) were
treated
with ultra violet (UV-C) radiation for 0, 5, 10, 15, 20, 30 and 60
minutes for the estimation of growth parameters and root infecting fungi
like Macrophomina phaseolina (Tassi) Goid, Rhizoctonia solani
Kühn and Fusarium spp. It was observed that both crop
plants showed increment in shoot weight, shoot length, root length and
root weight, leaf area and number of nodules when seeds of groundnut and
mung bean were treated with UV-C for 10, 15, 30 and 60 minutes period.
UV-C exposure for 0-60 minutes showed reduction in root infecting fungi
whereas 15, 20 and 30 minutes exposure with UV-C gave significant result
in increment of total chlorophyll and carbohydrate contents.
