The present study was carried out to estimate the comparative effects of hydroponic heavy metals (Al, Cd, Hg and Pb) on ATP content in plant leaves grown with Hoagland solution under green house condition. The two plants, kidneybean (Phaseolus vulgaris L.) and buckwheat (Fagopyrum esculentum Mo¨nch), showed similar inhibitory effect of heavy metals on ATP content in order of Hg, Cd, Pb and AI. But the overall inhibitory effect was greater in kidneybean than in buckwheat. The affinity of heavy metals, in vitro, toward th.. enzyme(luciferin.luciferase) is in order of Hg, Al, Cd and Pb, similar to that toward ATP. The results showed that the inhibitory effect of heavy metals on ATP hydroysis is mainiy due to the coordination of heavynetals with enzyme than ATP.
