反光膜对'阳光玫瑰'果实品质及挥发性物质的影响
Effects of Reflective Film on Fruit Quality and Volatile Components of'Shine Muscat'Grape
摘要
Abstract
In order to study the effect of different reflective films on the quality of grape fruits during the ripening period,6-year-old'Shine Muscat'was used as the experimental material,and silver grey reflective film(YH)and silver reflective film(YG)were laid along the tree row,taking the bare land without film as the control(CK).The temperature and humidity of the fruit part,the photosynthetic indices,the chlorophyll content of mature leaves were measured,and the fruit samples under different treatments were analyzed by metabolomics based on gas chromatography-mass spectrometry(GC-MS).The results showed that the YG treatment increased the daily average temperature and maximum temperature of the grape fruit positions by 1～2℃compared to CK,the daily and night accumulated temperatures of the grape fruiting area in this treatment were higher than those of CK and YH treatment.The application of 2 kinds of reflective films effectively improved the chlorophyll content and photosynthetic rate of grape leaves.On September 25,compared to CK the chlorophyll content of leaves in YH and YG treatments increased by 2.44％and 0.96％,the photosynthetic rate of leaves increased by 26.71％and 21.61％,the soluble solids increased by 10.79％and 17.15％,respectively,and vitamin C content increased by 11.00％in both YH and YG treatments,and the titratable acid content decreased by 33.93％and 26.79％,respectively.The relative contents of aldehydes,esters,alkanes,ketones and carboxylic acid metabolites in YG treatment fruits were higher than those in CK.YG treatment could significantly increase the contents of(E)-2-hexenal,nerolide acetate,cis-β-farnesene,3-Buten-2-one,4-(2,6,6-trimethyl-1-cyclohexen-1-yl)and so on,but most metabolites in YH treatment decreased.To sum up,laying reflective film could effectively improve the maturity of'Shine Muscat'fruit,and the effect of silver reflective film in particular was better.Above results provided basis for selecting suitable reflective film to promote the ripening of sunshine rose in northwest producing areas.关键词
