Abstract

Abstract: Using tomato as the experimental material, a pot experiment was conducted to explore the effects of two exogenous selenium fertilizers sodium selenite （Na₂SeO₃） and sodium selenate （Na₂SeO₄） on agronomic characters of tomato, selenium content and selenium 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 significantly 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 selenium significantly enhanced the ability of tomato plants to enrich selenium and transfer selenium from root to ground, increased the content 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.

Key words: exogenous selenium, tomato, selenium content, selenium accumulation, fruit quality
