摘　　要：【目的】以茄子为砧木嫁接番茄,综合评价茄砧嫁接对番茄生长、产量及品质的影响,进一步明确茄砧嫁接栽培的生物学效应,为该技术的应用提供理论依据。【方法】以托鲁巴姆为砧木,金棚9号为接穗,自根苗为对照,通过蛭石栽培方式,研究茄砧嫁接对番茄生长、产量、肥水利用率和品质的影响。【结果】嫁接后番茄植株的株高降低,叶片数减少,植株根、茎干鲜重降低,根冠比增加,植株光合色素含量增加,根系活力增强,单果重、单株结果数、单株产量降低;嫁接后增加了果实中Vc、可溶性糖含量,降低了可滴定酸,提高了糖酸比;可溶性固形物、番茄红素含量自根苗和嫁接苗无显著差异;嫁接后,降低了植株耗水量和矿质元素的吸收量,提高了水分和矿质元素的利用率。【结论】综合生长、产量、品质等指标,托鲁巴姆嫁接有助于番茄果实品质的提高,在嫁接栽培方面有一定利用价值。【Objective】Grafting tomato scions on rootstocks of eggplant(Solanum torvum)was evaluated for its applicability.【Method】Plant growth,tomato yield and quality as well as fertilizer and water utilization of the seedlings grown on meteorite in a greenhouse from the Jinpeng No.9 scions grafted on eggplant rootstocks were compared with those from the scions grafted on rootstocks of same variety(control).【Result】The S.torvum rootstock grafting retarded the plant height,leaf generation and weight gains on roots and stems of the grafted tomato seedlings but increased the root to shoot ratio,chlorophyll content and root activity.The individual weight,number per plant and yield per plant of the tomatoes decreased.The contents of Vc,soluble sugars and sugar/acid ratio of the fruits increased,while titratable acid decreased.No significant difference on the soluble solids and lycopene contents were observed between the seedlings grafted on S.torvum rootstocks and control.The water consumption and mineral absorption of the plants grafted on S.torvum rootstocks were less than those of control.【Conclusion】Overall,the growth,yield,quality and other indicators suggested that grafting tomato scions on S.torvum rootstocks would be suitable for application.
