Tree tomato (Solanum betaceum Cav.) is an economically important tree from the Andes. This species was grafted onto cucubo (Solanum stellatiglandulosum Bitter). Cucubo was the rootstock and 3 tree tomato cultivars were used as scions. Trees were cleft grafted by introducing a 15 cm long tree tomato scion onto cucubo. Grafted trees had a survival rate above 94%. Fruits derived from grafted trees were longer, wider, and heavier than ungrafted ones. Best fruit weight results occurred in the grafted común cultivar (193.7 g). Best fruit length results were obtained in the grafted mango cultivar (7.9 cm). Best fruit width occurred in the mora cultivar (6.7 cm). Grafted trees were more productive (about 30–40 fruits/tree) than ungrafted ones (about 10–15 fruits/tree). Fruit features were not modified in grafted trees i.e. color, shape, and taste. Large and small-scale growers worldwide could benefit from bigger-sized tree tomato fruits as a result of grafting. Grafting is key to improve tree tomato quality in global markets.

树番茄（Solanum betaceum Cav.）是来自安第斯山脉的一种重要的经济树种。该物种被嫁接到 cucubo ( Solanum stellatiglandulosum苦的）。Cucubo 是砧木，3 个树番茄品种被用作接穗。通过在 cucubo 上引入 15 厘米长的树番茄接穗来劈接树木。嫁接的树木成活率在94%以上。嫁接树木的果实比未嫁接的果实更长、更宽、更重。最好的单果重结果出现在嫁接的 común 品种 (193.7 g) 中。在嫁接的芒果品种 (7.9 cm) 中获得了最佳果实长度结果。最佳果实宽度出现在莫拉品种（6.7 厘米）中。嫁接的树木（每棵树约 30-40 个果实）比未嫁接的树木（每棵树约 10-15 个果实）的产量更高。嫁接树的果实特征没有改变，即颜色、形状和味道。由于嫁接，世界各地的大型和小型种植者都可以从更大尺寸的树番茄果实中受益。
