生物蛋白硒对'萨米脱'樱桃果实抗氧化能力及其品质的影响
Biological Protein Selenium on Antioxidant Capacity and Quality of'Samituo'Cherry fruits
摘要
Abstract
To explore the impact of organic selenium fertilizer spray on the antioxidant capacity and food quality of sweet cherries,"Samituo"cherry fruits are selected for experimentation.The study employs a randomized block design where cherry trees are treated with a biological protein selenium fertilizer at varying concentrations(0 mg/L,10 mg/L,30 mg/L,and 50 mg/L)during the pre-color change and color transformation stages of the fruit.This research assesses the selenium content in fruits and leaves,antioxidant enzyme activities,free radical scavenging abilities,and overall fruit quality in fruits post-treatment.The results show that the selenium content in both the cherry fruits and leaves increased as the concentration of applied selenium fertilizer is raised.Foliar application of selenium enhances the activity of antioxidant enzymes in the fruits,improves the free radical scavenging rate,and also increases the levels of Ca2+and vitamin C within the fruits.Notably,the 30 mg/L selenium treatment exhibits the most significant effects,markedly improving the activities of glutathione peroxidase (GSH-Px), thioredoxin reductase (TrxR), and the total antioxidant capacity (T-AOC) in the fruits compared to the control group (0 mg/L). Correlation analysis demonstrates a significant positive relationship between the selenium levels in the cherry fruits and several antioxidant parameters, including glutathione S-transferase (GST) and TrxR activities, superoxide anion radical (O2•−) scavenging ability, and total antioxidant capacity (T-AOC). This study provides a scientific foundation and theoretical guidance for cultivating selenium-enriched sweet cherries.关键词
