Abstract:
Application of 0.25% chitosan used as seed priming in (Phaseolus vulgaris L.) grown under varying degree of drought stress enhanced lignin and quinone content in the plant system. Seed primed plants showed positive response to bio primer and enhanced the quinone content in higher concentration compared to control and unprimed. Seed primed sample had lignin in a range of 0.049 to 0.823 and 0.074 to 0.954 mg/g DW in VL Rajma 63 and BR 104 verities respectively. Quinone was found in a range of 0.531 to 1.426 and 0.670 to 1.759 mg/g DW in VL Rajma 63 and BR 104 respectively. These lignin and quinone were secondary metabolites interconnected to strengthen the plant under stress. These lignin and quinone were the phenolic compounds biosynthesized from the phenylpropanoid pathway.
