Selenium Enrichment Ability and Quality Analysis of Processed Tomato in Natural Selenium-enriched Soil
Five different tomato varieties were chosen as the experimental subjects in the Yanqi basin,and two types of cultivated land were selected as experimental sites,including selenium-enriched land with a selenium content of 0.4 mg/kg in the soil,and non-selenium-enriched land with no detectable selenium content.The objective of this study was to analyze and evaluate the selenium enrichment ability and quality of these tomato varieties in natural selenium-enriched soil,and to identify the varieties that were suitable for local cultivation.The findings would provide a theoretical foundation for the development of the selenium-enriched industry in the Yanqi basin.The results revealed that the processed tomato varieties in selenium-enriched areas met the standards for selenium-enriched agricultural products and were considered natural selenium-enriched tomatoes.The varieties'Tunhe 1943','Tunhe 3501',and'Tunhe 5501'exhibited strong selenium enrichment abilities,with bioconcentration factors of 6.6%,6.6%,and 6.3%,respectively.Planting processed tomatoes in natural selenium-enriched soil improved the quality of the tomatoes,as evidenced by higher lycopene content in the selenium-enriched areas compared to the non-selenium-enriched areas.Furthermore,'Tunhe 3501'and'Tunhe 5501'had higher lycopene content than'Tunhe 1015','Tunhe 1943'and'Tunhe 17'.In selenium-enriched areas,the reducing sugar content of'Tunhe 1943','Tunhe 3501',and'Tunhe 17'was higher than that in non-selenium-enriched areas.The total acid content of processed tomatoes in selenium-enriched areas was also higher than that in non-selenium-enriched areas.'Tunhe 3501'had the highest total acid content,followed by'Tunhe 1943',and'Tunhe 1015'had the lowest content.A comprehensive analysis of the membership function demonstrated that'Tunhe 3501'performed the best overall in natural selenium-enriched soil,followed by'Tunhe 1943'.
