Effects of different exogenous selenium on selenium accumulation and fruit quality of tomato
Using tomato as the experimental material,a pot experiment was conducted to explore the effects of two exogenous selenium fertilizers sodium selenite(Na2SeO3)andsodium selenate(Na2SeO4)on agronomic characters of tomato,selenium content and seleni-um accumulation of tomato plants and fruit quality.The results showed that exogenous selenium application could promote the growth and development of tomato plants,and sodium selenate application could significantly increase tomato yield.Sodium selenate signifi-cantly increased selenium content in roots,stems,leaves and fruits of tomato plants,and the selenium absorption capacity of leaves was the strongest in this treatment,while that of roots was the strongest in sodium selenite treatment.The addition of exogenous seleni-um significantly enhanced the ability of tomato plants to enrich selenium and transfer selenium from root to ground,increased the con-tent of vitamin C and soluble sugar in tomato fruits,and significantly improved the quality of tomato fruits,and the effects of sodium selenate were superior to sodium selenite.
