摘要
为探究两收栽培模式下'瑞都红玉'葡萄单萜类物质积累的差异,本研究以6年生'瑞都红玉'葡萄为试材,通过对比分析'一'字形平棚架(简称棚架)和高宽垂'V'形篱架(简称篱架)两种栽培夏果、冬果的理化指标及游离态单萜类物质含量,得出不同栽培方式下'瑞都红玉'葡萄冬果和夏果的单萜类物质的积累差异.结果显示,夏果的果粒大小和质量均显著高于冬果;两种架式下冬果可滴定酸含量均高于夏果,但冬果篱架有利于可滴定酸含量的降低.此外,不同处理果实中均检测到24种游离态单萜类化合物,其中里哪醇含量最高,棚架下冬果含量最高达到了577.22 μg·L-1.利用主成分分析可以将夏果棚架、夏果篱架、冬果棚架、冬果篱架很好的区分,也进一步说明广西地区'瑞都红玉'葡萄利用棚架栽培条件下更有利于冬果单萜化合物的积累.本研究结果为该品种一年两收栽培的架式选择提供了重要的理论依据,为提升该品种葡萄的品质与产量奠定了基础.
Abstract
In order to exploring the accumulation patterns of monoterpenoids in'Ruidu Hongyu'grapes under different cultivation methods,using six-year-old'Ruidu Hongyu'grapes as the test material,by measuring the physicochemical indicators and free monoterpene content of summer fruits and winter fruits under'一'shaped flat shed frame and high width vertical'V'shaped fence frame cultivation,the research results showed that,berry size and weight of summer fruits were significantly higher than those of winter fruits.The titratable acid content of winter fruits was higher than that of summer fruits under both types of trellis cultivation,but winter fruit with'V'shaped fence frame cultivation was beneficial for reducing the titratable acid content.In addition,24 free monoterpenes were detected in the grape berries with different methods,and the highest content of Linalool,the highest content of 577.22 μg·L-1 in the winter fruit on'一'shaped flat shed frame.Different treatments were distinguished through principal component analysis(PCA),this also further indicated that under'一'shaped flat shed frame cultivation of'Ruidu Hongyu'grapes in Guangxi area was more benificial to the accumulation of monoterpenoids in winter fruits.The results of this study provided important theoretical basis for the selection of trellis systems under the cultivation of this variety with two-harvest-a-year,thereby improving the quality and yield of grapes.
