Silicon Enhances Resistance to Red Crown Rot Caused by Calonectria ilicicola in Soybean

Silicon (Si) application is known to enhance plant resistance diverse pathogens. Therefore, a greenhouse study was conducted determine whether Si reduces red crown rot (RCR) of soybean caused by the soil-borne fungal pathogen Calonectria ilicicola. The cultivar Enrei grown in soil mixed with different concentrations sodium silicate (Na2SiO3) and inoculated C. ilicicola (1% w/v). significantly reduced RCR severity relative growth roots, as per qPCR, at both sampling time points. Notably, shoot content correlated roots. In addition, accumulation malondialdehyde, indicating that maintenance cellular membrane integrity an important mechanism underlying Si-mediated protection plants from RCR. Furthermore, Si-treated exhibited improved water nitrogen uptake root growth. Aboveground biomass seed yield harvest increased increasing concentration (0.0–3.0 g Na2SiO3 kg−1 soil). However, further increase (6.0 soil) yield. treatment can be used effective strategy control soybean.
