Table 1 Effect of an exogenous hemin (0.5 mM) on biomass, height, tolerance index, leaf water content and chlorophyll (Chl a, Chl b and Total Chl) content in seedlings of V. radiata treated with CdCl2 (50 µM) for a period of 96 h.

From: Exogenous hemin improves Cd2+ tolerance and remediation potential in Vigna radiata by intensifying the HO-1 mediated antioxidant defence system
