Interaction of lycorine with UV-B and kinetin in cucumber (Cucumis sativus L.) Cotyledons

Interaction of lycorine, a strong inhibitor of ascorbic acid biosynthesis with kinetin and UV-B radiation has been studied in cucumber (Cucumis sativus L.) cotyledons. Lycorine inhibited hypocotyl growth of seedlings as well as kinetin induced expansion growth of cotyledons in darkness. Exposure to UV-B radiation has similar inhibitory effect on growth. Inhibition of growth by lycorine was accompanied by inhibition...

Adathoda vasica leaf extract induces resistance in rice against bacterial leaf blight disease (Xanthomonas oryzae pv. oryzae)

Three plants extracts were used for the management of Xanthomonas oryzae pv. oryzae in vitro. The efficacy of the plant extracts was tested by antibacterial activity and was used as seed treatment to know the enhancement of seed germination and seedling vigour. Beside promising results given, plant extracts were tried under greenhouse studies to test the efficacy in controlling bacterial blight disease...
