Effects Of Different Dwarf Training Patterns On Volatile Flavor Compound Of Cabernet Gernischt

In order to study the effect of different dwarf training patterns on berry of volatile flavor compounds of Cabernet Gernischt.In this study,14-year-old Vitis vinifera cv.Cabernet Gernischt were used as experimental materials.In the condition of dwarf Lord tendril,it studied the influence of four kinds of patterns to volatile flavor compounds?sugar?acid?pigment and tannin,included Vertical Cordon(CK),Cup(T1),Guyot simple(T2)and Horizon Cordon without trunk(T3).The results showed as follows:for1?Compared with the control,they had the same influence the different training patterns,such as the soluble solids,soluble total sugar and reducing sugar all change the content of each indication to a contain content.The TA and tannin was highest in T1.The T2 and T3 improved the fruit anthocyanins and total phenol content,but the 100 fruits weight of under T3 was significantly lower than that of CK.The different dwarf training systems had a great effect on the quality of Cabernet Gernischt.2.There were some different effects on the growth and development of grape for the four kinds of training patterns.The T3 had the highest relative expression of Vv-Ecar,VvCCDl and Vvter in grape.The VvLis relative expression was highest in CK,T3 was the second highest,it was indicated that T3 can improve the genes expression level of volatile flavor compounds synthesis.3?In the four kinds of dwarf training patterns condition,there were detected in 68 kinds of volatile flavor compounds in mature period,including 19 alcohols,14 esters,6 acids,8 aldehydes,7 ketones and 14 others by GC/MS.4.The main volatile flavor compounds constituent of Cabernet Gernischt were composed by 12 alcohols,13 esters and 5 acids;The total content of aldehydes and others in Goblet dwarf-training patterns was the highest,and the total content of ketones by 12 was the highest,but the total amount of volatile flavor substances in the T3 was the highest.In consequence,T2 and T3 were beneficial to improve the grape berry quality,the T3 fruit volatile flavor compounds synthesis of genes related to the expression of the best and the total amount of volatile flavor substances was the highest Meanwhile,therefore,we suggested the usage of T3(Horizontal Cordon without trunk)training system.
