外源硒代蛋氨酸添加和亏缺灌溉对番茄果实品质的影响
The Effects of Exogenous Selenomethionine Supplementation and Deficit Irrigation on Tomato Fruit Quality
摘要
Abstract
To study the effects of exogenous selenomethionine supplementation and water deficit irrigation on tomato fruit quality,'Jingcai No.8' was used as the experimental material.The effects of water deficit treatment and selenomethionine supplementation on the appearance quality,flavor quality,plant yield,antioxidant enzyme activity,and expression of related genes in mature tomato fruits were analyzed in detail.The results showed that under W0(well-watered)conditions,Se1(selenomethionine supplementation)significantly deepened the color of tomato fruits,increased catalase(CAT)activity,single-plant yield,soluble solids,and VC content,and significantly decreased titratable acidity.Under W1(water deficit)conditions,Se1(selenomethionine supplementation)increased single-plant yield and fruit soluble solids content,but significantly reduced superoxide dismutase(SOD)activity,VC content,and peroxidase(POD)and CAT activity.At the gene expression level,differences were observed in the expression of genes related to carotenoid and sugar metabolism and antioxidant defense.Therefore,exogenous selenomethionine supplementation not only helps improve the quality of tomato fruits under water deficit irrigation but also alleviates the negative effects of water deficit irrigation on plant yield.关键词
