The present investigation has been carried to find out the different concentration of lead on biochemical changes of horse gram (Dolichos biflorous Linn.) seedlings.the seeds were procured from tamilnadu agricultural university (TNAU) coimbatore.Three varieties of horse gram seeds were used for this experiment.various concentration of lead acetate solutions were prepared .(5,10,25,50,75,100,250,500 and 1000 ppm by using distilled water.the seedlings under 500 and 1000 ppm lead acetate concentration were found to be leathal.The biochemical studies such as chloriphyll ‘a”chlorophyll ‘b’ total chlorophyll,carotenoid,sugars,starch,amino acids,protien and prolinehave been studied.
