Selenium biofortification is an effective way to improve the tomato fruit quality, however, it is affected by the selenium fertilizer types, selenium fertilizer application methods, selenium fertilizer concentrations, and tomato varieties. We performed 696 pairs of data for meta-analysis using a random-effects model to study the effects of selenium fertilizer application on tomato fruit quality. The results showed that selenium fertilizer application had a significant positive effect on most nutritional quality variables of tomatoes, while there was no change in nitrate content (SMD=−0.557; 95% CI: −2.1∼0.987) and fruit firmness (SMD=0.172; 95% CI: −0.077∼0.422) of tomatoes under application of selenium fertilizer, and similar conclusions were also drawn on nutrients (except for Fe and Ca). For different types of selenium fertilizer, the response of most tomato quality variables to Na2SeO3 was more significant than that to Na2SeO4. The response of tomato quality variables to selenium fertilizer application methods was different, furthermore, the total soluble solids, sugar-acid ratio, and vitamin C improved the most in soil fertilization, while the concentrations of soluble sugar, titratable acid, and lycopene increased the most in leaf spraying. In terms of selenium concentrations, the concentrations of total soluble solids, vitamin C, and nitrate content increased the most when the concentration was 1∼5 mg·L−1, while the concentrations of soluble sugar, titratable acid, and lycopene improved the most when the concentration exceeds 5 mg·L−1. For tomato varieties, the improvement of nutritional quality variables of small fruits was better than that of big fruits. Our meta-analysis comprehensively evaluated the response of tomato quality variables to the application of selenium fertilizer and provided an important guide for higher-quality selenium biofortified tomatoes.

硒肥施用和番茄品种对番茄果实品质的影响:荟萃分析

硒生物强化是提高番茄果实品质的有效途径,但受硒肥种类、硒肥施用方式、硒肥浓度、番茄品种等因素影响。我们使用随机效应模型对 696 对数据进行了荟萃分析,以研究硒肥施用对番茄果实品质的影响。结果表明,施硒肥对番茄的大部分营养品质变量有显着的正向影响,而硝酸盐含量(SMD=-0.557;95% CI:-2.1∼0.987)和果实硬度(SMD=0.172)没有变化。 ; 95% CI: -0.077∼0.422) 的番茄在施用硒肥的情况下,对养分(除了Fe 和Ca)也得出了类似的结论。针对不同类型的硒肥,2 SeO 3比Na 2 SeO 4更显着。番茄品质变量对硒肥施用方式的响应不同,土壤施肥中总可溶性固形物、糖酸比和维生素C的改善最大,而可溶性糖、可滴定酸和番茄红素的浓度增加了土壤施肥方法。以叶面喷施最多。在硒浓度方面,总可溶性固形物、维生素C和硝酸盐含量在浓度为1~5 mg·L -1时增幅最大,而可溶性糖、可滴定酸和番茄红素浓度增幅最大当浓度超过5 mg·L -1. 对于番茄品种,小果实营养品质变量的改善优于大果实。我们的荟萃分析全面评估了番茄品质变量对硒肥施用的响应,为更高品质的硒生物强化番茄提供了重要指导。
