Silicon promotes nodule formation and nodule function in symbiotic cowpea (Vigna unguiculata)


, : Silicon promotes nodule formation and nodule function in symbiotic cowpea (Vigna unguiculata). New Phytologist 142(3): 463-467

Applying silicon in the form of metasilicic acid (H<sub>4</sub>SiO<sub>3</sub>) or silicic acid (H<sub>4</sub>SiO<sub>4</sub>) to Bradyrhizobium-infected, hydroponically grown cowpea seedlings resulted in a significant increase in the number of nodules, nodule dry matter, and nitrogen fixed on a per plant basis. Total dry matter of plants increased with silicon supply, and the differences were significant at the higher silicon concentrations.
