摘要: Abstract Effect of Si on alleviation Mn toxicity barley (Hordeum vulgare L.) seedlings was investigated with special reference to the effect microdistribution and peroxidase activity. Manganese treatment conducted by growing in nutrient solutions containing different concentrations Mn. Silicon or without supply. supply alleviated necrotic browning leaves but did not affect chlorosis caused toxicity. appreciably alter uptake plants. Electron probe X‐ray microanalysis revealed that accumulated high concentration around brown spots prevented uneven distribution tissues. Increase level an increase activity tissues, prvented
