Silicon seed priming attenuates cadmium toxicity in lettuce seedlings.

This study aimed to evaluate the silicon (Si) capacity to attenuate the cadmium (Cd) effects on seed germination and seedling performance of lettuce. The seeds were subjected to three priming levels: without priming, hydropriming, and Si priming. Afterwards, the seeds were placed to germinate on paper moistened with the absence (0 mM) and presence (1 mM) of Cd.
