Lead (Pb) is one of the most abundant heavy metal pollutants, which can penetrate the plant through the root and then enter the food chain causing in potenti ...

The pressure generated by the increase in volume of the anthers during microsporogenesis modifies the surface of the stigma and style, generating depressions (Figure 5i -j). Phase 2 (pre-anthesis at ...
