With three grape varieties, Red Barbara, Summer Black and Hutai No. 8 as test mate-rials, we investigated the effects of foliar spraying of organic selenium fertilizer on greenhouse grape quality and selenium content. The results showed that spraying 12 mg·L amino acid chelated selenium-enriched foliar fertilizer on grape leaves significantly increased selenium content and the quantity and quality of grape yield, including the contents of soluble sugar, organic acid, soluble protein, soluble solids, vitamin C and proanthocyanidins. However, there was no increase in resveratrol. Among the three varieties, selenium content of Summer Black in 2017 and 2018 was increased by 36.7% and 37.1%, respectively, being higher than that of Red Barbara and Hutai No. 8. Red Barbara sprayed with selenium fertilizer had better quality due to high sugar and low acid contents, as well as high health-care components. Moreover, the selenium content of Hutai No. 8 in 2018 was 53.26 μg·kg, higher than the others, indicating a stronger ability of selenium enrichment. We concluded that the increase range of Se content was larger in Summer Black, Red Barbara showed the better nutrition value and quality, and Hutai No. 8 was a suitable variety for selenium-rich grape production.
以红芭拉蒂、夏黑和户太8号三个葡萄品种为试验材料，研究了叶面喷施有机硒肥对温室葡萄品质和硒含量的影响。结果表明，在葡萄叶片上喷施12 mg·L氨基酸螯合富硒叶面肥，可显著提高葡萄的硒含量以及葡萄产量的数量和质量，包括可溶性糖、有机酸、可溶性蛋白、可溶性固形物、维生素C和原花青素的含量。然而，白藜芦醇含量没有增加。在这三个品种中，2017年和2018年夏黑的硒含量分别提高了36.7%和37.1%，高于红芭拉蒂和户太8号。喷施硒肥的红芭拉蒂因含糖量高、含酸量低以及保健成分含量高而品质更佳。此外，2018年户太8号的硒含量为53.26 μg·kg，高于其他品种，表明其富硒能力更强。我们得出结论，夏黑中硒含量的增加幅度更大，红芭拉蒂表现出更好的营养价值和品质，户太8号是适合生产富硒葡萄的品种。
