Abstract This paper presents the chemical composition of the fruits of three European plum cultivars (‘Cacanska Rana’, ‘Cacanska Lepotica’, and ‘Cacanska Najbolja’) grafted on four rootstocks (Myrobalan, ‘Pixy’, ‘Fereley’, and ‘St. Julien A’). The rootstock/cultivar combinations significantly influenced the content of most of the phenolic compounds in the plum skin and flesh. The total anthocyanin content in the skin ranged from 1.87 to 7.33 mg cyanidin-3-glucoside g−1 fresh weight. The major phenolic compound in the skin was rutin, which ranged from 95 to 238 mg kg−1, while in the flesh, cinnamic acid and catechin were dominant. The total sugar content in the fruit ranged from 66.2–147 mg g−1. The highest glucose and fructose contents were in ‘Cacanska Lepotica’, then in ‘Cacanska Najbolja’, and the lowest were in ‘Cacanska Rana’ cultivar. The highest contents of glucose and sucrose were found in fruits from trees grafted on Myrobalan rootstock, and the lowest in fruits from trees grafted on ‘St. Julien A’ rootstock. The rootstocks significantly influenced the potassium, calcium, and copper contents in the plum fruit. The results of this study demonstrate the significant effect of rootstocks on the phenolic and sugar profiles, and on the mineral content of the plum fruits.

砧木对李子品种果实化学成分的影响

摘要 本文介绍了三种欧洲李子品种（'Cacanska Rana'、'Cacanska Lepotica' 和 'Cacanska Najbolja'）嫁接在四种砧木（Myrobalan、'Pixy'、'Fereley' 和 'St . 朱利安 A')。砧木/品种组合显着影响了李子皮和果肉中大部分酚类化合物的含量。皮肤中的总花青素含量为 1.87 至 7.33 mg cyanidin-3-glucoside g-1 鲜重。皮肤中的主要酚类化合物是芦丁，范围为 95 至 238 mg kg-1，而肉中的主要酚类化合物是肉桂酸和儿茶素。水果中的总糖含量为 66.2-147 mg g-1。'Cacanska Lepotica' 的葡萄糖和果糖含量最高，然后是'Cacanska Najbolja'，最低的是'Cacanska Rana' 品种。嫁接在 Myrobalan 砧木上的果实中葡萄糖和蔗糖含量最高，而嫁接在 'St. 砧木上的果实中葡萄糖和蔗糖含量最低。Julien A' 砧木。砧木对李子果实中钾、钙和铜的含量有显着影响。这项研究的结果表明砧木对李子果实的酚类和糖类成分以及矿物质含量有显着影响。
