减施氮磷肥对'赤霞珠'葡萄果实类黄酮物质的影响
Effect of Reduced Nitrogen and Phosphorus Fertilization on Flavonoids in'Cabernet Sauvignon'Grape Berries
摘要
Abstract
In order to investigate the effects of different fertilization strategies on the fruit quality of'Cabernet Sauvignon'grapes in the Manas region of Xinjiang,this study used the conventional full fertilization(600 kg·ha-1 urea and 300 kg·ha-1 diammonium phosphate,N∶P2O5=2.3∶1)as the control(CK),and set up three treatments:T1(474 kg·ha-1 urea and 396 kg·ha-1 DAP,adjusted fertilization ratio to N∶P2O5=1.5∶1),T2(450 kg·ha-1 urea and 225 kg·ha-1 DAP,75%of CK),and T3(300 kg·ha-1 urea and 150 kg·ha-1 DAP,50%of CK).Vine growth indicators,yield,fruit physicochemical properties,and the composition and content of flavonoids under different treatments were measured.The results showed that all of the three treatments had no significant effect on the physical and chemical indicators of the fruits and the vigor of the vines.However,all of the three treatments significantly increased the content of anthocyanins,with T2 treatment showing the greatest effect.Furthermore,T1 treatment significantly increased the content of flavonols,while no treatment affected the total flavanols content compared with the control.The principal component analysis based on the content of flavonoids revealed that the composition and content of flavonoids were closely related to the amount and proportion of fertilizer applied.According to the membership function-based comprehensive evaluation,the overall effects of different treatments on flavonoid accumulation ranked as follows:T2＞T1＞T3＞CK.Based on the above results,under the present experimental conditions,it is recommended to adopt the fertilization scheme of 75%conventional full fertilization(T2),which can maintain normal vegetative growth of grapevines while helping to improve the potential wine-making quality of the grapes.关键词
