The effect of cultivation practices for controlling strawberry black root rot (BRR) on fruit quality, antioxidant capacity, and flavonoid content in two strawberry cultivars Allstar and Chandler (Fragaria x ananassa Duch.) was evaluated. Strawberry fruits used in this study were from plants grown in soils which had a prior history of BRR and red stele, and had not been fumigated during the seven years prior to the study. Results from this study showed that fruit from plants grown in compost socks had significantly higher oxygen radical absorbance capacity (ORAC), flavonoids, anthocyanins, soluble solids content (SSC), titratable acid (TA), fructose, glucose, sucrose, malic acid, and citric acid than fruit produced in the black plastic mulch or matted row systems. Cultivar Chandler surpassed cv. Allstar in sugar content, acid content, and flavonoid content regardless of preplanting vinegar drenching and various culture treatments. However, preplanting vinegar treatment increased cyanidin-based and pelargonidin-based anthocyanins but decreased sugar content in fruits of both cultivars.
本研究评估了栽培措施对控制草莓（Fragaria x ananassa Duch.）黑根腐病（BRR）的影响，以及对两个草莓品种全明星（Allstar）和钱德勒（Chandler）果实品质、抗氧化能力和类黄酮含量的影响。本研究使用的草莓果实来自于先前发生 BRR 和红色髓部病害、且在研究前七年未进行熏蒸处理的土壤中生长的植株。研究结果表明，与黑色塑料地膜或垄作系统相比，生长在堆肥套中的植株所结的果实具有更高的氧自由基吸收能力（ORAC）、类黄酮、花青素、可溶性固形物含量（SSC）、可滴定酸（TA）、果糖、葡萄糖、蔗糖、苹果酸和柠檬酸。无论是否进行定植前醋液灌根处理以及采用不同的栽培措施，品种 Chandler 的糖、酸和类黄酮含量均高于 Allstar 品种。然而，定植前醋液处理增加了两个品种果实中基于矢车菊素和天竺葵素的花青素含量，但降低了果实中的糖含量。
