硒肥、叶面肥和植物生长调节剂配施对巨峰葡萄果实品质及香气物质的影响
Effects of combined application of selenium fertilizer,foliar fertilizer,and plant growth regulators on fruit quality and aroma components of'Kyoho'grape
摘要
Abstract
Aiming at the problems of single aroma components and low yield in winter-harvested'Kyoho'grapes in continuous cropping areas of central Guangxi(Chengtuan Town,Liujiang District,Liuzhou City),a study was conducted using an L9(34)orthogonal experimental design with four factors and three levels:selenium fertilizer,foliar fertilizer,2,4-epibrassinolide,and 20%propyl dihydrojasmonate(PDJ).The results showed that the single fruit weight of Treatment 4 reached 6.93 g.Treatment 2 had the highest fruit shape index(1.11),which was significantly higher than that of the control(CK).The soluble solids content of Treatment 1 was 21.23%,significantly higher than other treatments.Treatment 7 had the highest solid-acid ratio(67.4),which were significantly higher than other treatments.The L*,a*,and b* values of Treatment 1 were significantly lower than those of CK,and its color index CIRG was the highest(3.62),followed by Treatment 2.Metabolomic analysis of grape aroma was performed on the two treatments with the best fruit coloring and the control group.A total of 429 volatile compounds were detected,and significant differences were observed among treatments.There were 27 differential metabolites between Treatment 1 and the control,including 18 up-regulated and 9 down-regulated substances.Between Treatment 2 and the control,there were 44 differential metabolites,including 23 up-regulated and 21 down-regulated substances.The main aroma compounds detected in'Kyoho'grapes included ethyl acetate,ethyl valerate,trans-2-decenoate,ethyl propionate,hexanal,decanal,n-hexanal,(E)-2-hexenol,dimethylbutanal,ethyl hydroxybutyrate,phenylethanol,and 1,3-di-tert-butylbenzene.In conclusion,the optimal combination for improving fruit shape index,fruit coloring,soluble solids content,and aroma accumulation in'Kyoho'grapes was Treatment 1(A1B1C1D1),which involved spraying 10 mg/L selenium fertilizer+600-fold dilution of high-nitrogen and high-potassium foliar fertilizers+0.02 mg/L 2,4-epibrassinolide+50 mg/L 20%PDJ.关键词
