摘　　要：为了明确草莓内源SA(Salicylic acid,简称SA)含量与其抗病性的关系,并探索人们从草莓等植物性食物中摄取SA的总量,用HPLC分析比较了露地与设施栽培条件下五个对白粉病抗性不同的草莓品种果实的SA含量。结果表明,所测五种草莓红熟期果实内源总SA含量差别明显,露地栽培条件下为1.904～5.023μg/g,设施栽培条件下为1.068～4.201μg/g,与各品种的抗白粉病能力无明显相关性。草莓果实中SA均以结合态为主,五个品种结合态SA含量是游离态SA的4～20倍。游离态SA和结合态SA含量都随着果实的成熟而逐渐下降。说明草莓果实中内源SA含量不仅受基因型的影响,并且受栽培环境和成熟度的影响。In order to clarify the relation between the endogenous salicylic acid content of strawberry fruit and its diseases resistance, and to help estimating the amount of SA taken from fruit comsumptioin by people, HPLC was used to measure the SA content of five varieties of strawberry which are susceptible or resistant to powdery mildew in open field and plastic simple greenhouse. The results showed that SA contents are greatly different among five strawberry varieties in two cultivation conditions, 1.904-5.023 μg/g in open field and 1.068-4.201 μg/g in plastic simple greenhouse respectively. There is no correlative relationship between endogenous SA contents in the fruits and their resistant ability against powdery mildew. Bound SA was the predominant form of endogenous SA in strawberry fruits with being 4 to 20 times as high as free SA in the measured five varieties of strawberry fruits. Both endogenous free SA and bound SA of strawberry fruit were declined gradually with the fruit maturity. It is suggested that SA content in strawberry fruits is controlled not only by genotype, but also by the cultivation and the environment.
