背景
在粉质壤土上建立了三种不同的灌溉制度-田间持水量上限（UFC），-12kPa）;田间持水量下限（LFC），-33kPa;和亏缺灌溉（DI），-70kPa），并用张力计监测。对“弗拉门戈”和“伊娃的喜悦”常结果草莓品种的产量和果实品质进行了监测。采用高效液相色谱-质谱联用技术（HPLC/HPLC-MS），研究了不同灌溉制度对葡萄糖、有机酸和酚类化合物含量的影响。
结果
亏缺灌溉显著增加了糖的含量（从1.1- 1.3倍），有机酸（从1.1- 1.3倍），它们的比例（从1.1- 1.2倍）和最确定的酚类物质的含量在CV。弗拉门戈相反，较高量的总糖和有机酸（1.7至1.8倍）检测到在'伊娃的喜悦'草莓在UFC和LFC灌溉。亏缺灌溉普遍降低了草莓产量。“伊娃的喜悦”。
结论
结果表明，草莓品种在微亏灌溉条件下生长的果实品质和口感上级。弗拉门戈© 2016化学工业协会。
BACKGROUND
Three different irrigation regimes - upper limit of field capacity (UFC), -12 kPa); lower limit of field capacity (LFC), -33 kPa; and deficit irrigation (DI), -70 kPa) were established on silty-loam soil and monitored with tensiometers. Yield and fruit quality of 'Flamenco' and 'Eva's Delight' ever-bearing strawberry cultivars were monitored. The aim of the study was to evaluate the effect of different irrigation regimes on the content of sugars, organic acids and phenolic compounds using high-performance liquid chromatography-mass spectrometry HPLC/HPLC-MS.
RESULTS
Deficit irrigation significantly increased the content of sugars (from 1.1- to 1.3 fold), organic acids (from 1.1- to 1.3-fold), their ratio (from 1.1- to 1.2-fold) and the content of most identified phenolics in cv. 'Flamenco'. Conversely, higher amounts of total sugars and organic acids (1.7- to 1.8-fold) were detected in 'Eva's Delight' strawberries at UFC and LFC irrigation. Deficit irrigation generally decreased strawberry yield of cv. 'Eva's Delight'.
CONCLUSION
The results suggest superior fruit quality and taste of strawberries grown under minor deficit irrigation for cv. 'Flamenco'. © 2016 Society of Chemical Industry.
