Study shows that petunia cultivars vary in silicon accumulation and distribution
Silicon ( Si ) is a works - beneficial element that can palliate the effects of abiotic and biotic stress . Plants are typically classified as Si collector based on foliar Si concentrations ( ≥1 % Si on a dry exercising weight basis for accumulators ) . By this definition , most greenhouse - grow ornamentals are low Si accumulators . However , plants that accumulate low foliar Si concentrations may still collect high Si concentrations elsewhere in the plant ....
