Some results regarding the influence of some Solanum rootstocks on eggplant crops from Romania are in this study. Eggplants are popular vegetables all around the world. Among the grafting aims are fruit yield and quality. Eggplant grafting has been a tradition for over 15 years at the Horting Institute from Bucharest. Grafting combinations used have been the S. melongena scions (Aragon F1 from Hazera, Israel and Luiza variety from the Research–Development Institute Vidra, Romania), the S. lycopersicum x S. habrochaites rootstock (Emperador F1 from Rijk Zwaan, Nethelands) and the S. melongena rootstock (L23B eggplant hybrid from germplasm colection of the Research Station Buzău, Romania). By comparing the fruit yield and carbohydrates content of the grafted or non-grafted variants, the grafted eggplants have had outstanding results, values higher than at control eggplants. Production increment has been up to 25.44% (Luiza x Emperador). Carbohydrate content has increased up to 0.14% (Aragon x Emperador). Researches on the identification of some rootstocks compatible with eggplant scions continues in Romania.
