Keywords

Seedling of mungbean (Vigna radiate) were raised in the pots to evaluate the effect of lead on growth, chlorophyll and nitrate reductase activity. The plants grown with increasing level of lead were reduced in germination in and growth compared to control plants. Chlorophyll content, carotenoids, soluble protein and organic nitrogen contents remained almost unaffected at lower concentration of lead tested. Enzyme activity in vitro and in vivo in excised leaves showed marked increase at lower concentration of lead. Chlorophyll carotenoids soluble protein and organic nitrogen contents remained almost unaffected at lower concentrations of lead tested. Thus lead shows the inhibition or reduction in growth and germination at higher concentration thus leads the decrease in chlorophyll level also. Inhibition in enzyme activity (in vitro and in vivo) also reported in excised and intact mungbean in presence of lead. It seems that nitrate reductase has a different response towards lead pollution in which is more tolerant to lead pollution Vigna radiata.
