摘要/Abstract

摘要： 以番茄为供试材料,采用盆栽试验,研究了2种外源硒亚硒酸钠（Na₂SeO₃）和硒酸钠（Na₂SeO₄）对番茄农艺性状、番茄植株各器官硒含量、硒的富集及番茄果实品质的影响。结果表明,外源硒施用可促进番茄植株的生长发育,且硒酸钠施用可显著提高番茄产量;硒酸钠施用显著增加了番茄植株根、茎、叶、果实中的硒含量,且叶对硒的吸收能力最强,而亚硒酸钠处理中根对硒的吸收能力最强;外源硒的添加显著增强了番茄植株对硒的富集能力及从根系向地上部转移硒的能力,提高了番茄果实维生素C及可溶性糖含量,显著改善了番茄果实的品质,且硒酸钠的效果优于亚硒酸钠。

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
