The purpose of this study is to determine the effects of selenium (Se) on cherry tomato fruits under cadmium (Cd) stress. Methods: Se (2.5 μM) was applied to hydroponic solution with different concentrations of Cd (10 μM and 50 μM). The yield, quality, mineral elements, and Cd contents of cherry tomato was determined. Ten micromolars of Cd had no effect on the appearance and quality of cherry tomato, while 50 μM Cd significantly reduced the content of vitamin C, lycopene, soluble solids, and soluble sugars in the fruits. Cd stress significantly reduced cherry tomato fruit yield and also inhibited the accumulation of mineral elements such as calcium, magnesium, and iron in the fruits, and these inhibitory effects increased with the increase of Cd concentration. Besides, Se application significantly increased fruit yield by 8.38% and 8.56% under 10 μM and 50 μM Cd stress, respectively, when compared with plants grown without Se. Exogenous application of Se also significantly increased vitamin C, lycopene, and soluble sugar contents of fruit under 50 μM Cd stress and effectively promoted the accumulation of calcium, iron, copper, and zinc in the fruits. In addition, Se significantly reduced the Cd contents in roots, stems, and leaves of cherry tomato plants under 10 μM and 50 μM Cd stress, thereby leading to 12.85% and 12.48% respective decrease in the Cd content in fruits when compared with plants grown without Se. Therefore, applying Se can effectively improve the yield and quality of cherry tomato fruits under Cd stress and also reduce the Cd content in fruits.

这项研究的目的是确定硒（Cd）胁迫下硒对樱桃番茄果实的影响。方法：将Se（2.5μM）应用于不同浓度的Cd（10μM和50μM）的水培溶液中。测定了樱桃番茄的产量，品质，矿质元素和Cd含量。十微摩尔Cd对樱桃番茄的外观和品质没有影响，而50μMCd则显着降低了水果中维生素C，番茄红素，可溶性固形物和可溶性糖的含量。镉胁迫显着降低了樱桃番茄的产量，并且抑制了钙，镁和铁等矿质元素的积累，这些抑制作用随着镉浓度的增加而增加。此外，施用硒显着提高了水果产量，分别提高了8.38％和8。与不含Se的植物相比，在10μM和50μMCd胁迫下分别有56％的人。在50μMCd胁迫下，Se的外源施用还显着提高了果实中的维生素C，番茄红素和可溶性糖含量，并有效促进了钙，铁，铜和锌在果实中的积累。此外，硒显着降低了10μM和50μMCd胁迫下樱桃番茄植物的根，茎和叶中Cd含量，从而导致与生长的植物相比，果实中Cd含量分别降低了12.85％和12.48％。没有硒。因此，施用硒可以有效提高镉胁迫下樱桃番茄果实的产量和品质，并降低果实中的镉含量。在50μMCd胁迫下，Se的外源施用还显着增加了果实中的维生素C，番茄红素和可溶性糖含量，并有效促进了钙，铁，铜和锌在果实中的积累。此外，硒显着降低了10μM和50μMCd胁迫下樱桃番茄植物的根，茎和叶中Cd含量，从而导致与生长的植物相比，果实中Cd含量分别降低了12.85％和12.48％。没有硒。因此，施用硒可以有效提高镉胁迫下樱桃番茄果实的产量和品质，并降低果实中的镉含量。在50μMCd胁迫下，Se的外源施用还显着提高了果实中的维生素C，番茄红素和可溶性糖含量，并有效促进了钙，铁，铜和锌在果实中的积累。此外，硒显着降低了10μM和50μMCd胁迫下樱桃番茄植株的根，茎和叶中Cd含量，从而导致果实中Cd含量与生长的植物相比分别降低了12.85％和12.48％没有硒。因此，施用硒可以有效提高镉胁迫下樱桃番茄果实的产量和品质，并降低果实中的镉含量。硒显着降低了10μM和50μMCd胁迫下樱桃番茄植株的根，茎和叶中Cd含量，与无Se种植的植物相比，导致果实中Cd含量分别降低了12.85％和12.48％。因此，施用硒可以有效提高镉胁迫下樱桃番茄果实的产量和品质，并降低果实中的镉含量。硒显着降低了10μM和50μMCd胁迫下樱桃番茄植株的根，茎和叶中Cd含量，与无Se种植的植物相比，导致果实中Cd含量分别降低了12.85％和12.48％。因此，施用硒可以有效提高镉胁迫下樱桃番茄果实的产量和品质，并降低果实中的镉含量。
