Zinc priming promotes seed germination and seedling vigor of rice

The present study evaluated effects of seed zinc (Zn) priming at concentrations from 0 to 25 mM ZnSO4 on seedling vigor and viability in rice (Oryza sativa L.). Zinc priming substantially increased Zn concentration in the husk, but not in brown rice. The movement of primed Zn from the husk into the...
