摘要:

【目的】分析不同品种砧木嫁接的樱桃番茄植株生长状况、经济性状、果实性状和品质,为南方秋冬番茄生产选用砧木新品种提供参考依据。【方法】以番茄砧木番砧3号、茄子砧木茄砧11号、茄砧21号和本地茄砧为砧木,粉红色樱桃番茄品种为接穗,以自根苗为对照(CK),进行嫁接栽培效果对比试验,测定植株高度、叶片数、经济性状、果实性状和品质等相关指标,采用隶属函数法综合评价不同砧木嫁接樱桃番茄的栽培效果。【结果】番砧3号和茄砧21号嫁接的樱桃番茄单株果穗数、成熟果数和单穗果数等经济指标均显著多于自根苗(P<0.05,下同),单株产量显著高于本地茄砧嫁接苗和自根苗,果实萼片和果柄的综合性状最佳。不同品种砧木均可不同程度提高嫁接樱桃番茄果实的硬度、外果皮厚度和果面色泽比h,提高耐贮运性和外观品质。不同品种砧木嫁接樱桃番茄果实的可溶性固形物、维生素C(Vc)和番茄红素含量等品质指标均比自根苗高。【结论】番砧3号和茄砧21号可作为华南地区秋冬樱桃番茄嫁接栽培优先选用的砧木品种。

【Objective】Growth situation, economic characters, fruit characters and quality of cherry tomato grafted on different stocks were analyzed, which provided reference for selection of new stock varieties for tomato planting in autumn and winter in southern China. 【Method】Pink cherry tomato cultivar was grafted onto Fanzhen No.3, Qiezhen No.11, Qiezhen No.21 and local Qiezhen, non-grafted seedling was taken as control(CK). The following parameters of grafted seedlings were recorded: plant height, leaf number, economic characters, fruit characters and fruit qualities. The comprehensive effects of grafting seedlings on different stocks were evaluated by membership function. 【Result】Economic indexes of seedlings grafted on Fanzhen No.3 and Qiezhen No.21 were significantly higher than those of control, including ear number per plant, ripe fruit number per plant and fruit number per ear(P<0.05, the same below). Besides, their yields per plant was significantly higher than those of seedlings grafted on local Qiezhen and non-grafted seedling, and their synthetic performance of fruit sepals and fruit stalks were the best. Different stocks could improve fruit hardness, peel thickness and color parameter h to various extents, and enhance the storage property and appearance quality. Fruit soluble solids, vitamin C(Vc), lycopene content and other quality indicators of grafted seedlings were higher than those of non-grafted seedling. 【Conclusion】Fanzhen No.3 and Qiezhen No.21 can be used as preferred stock varieties in grafting of cherry tomato in autumn and winter in southern China.
