The scientific research is concerned continuously of achieving some high value biological creations, resistant or tolerant to diseases and pests, high productivity, high quality fruits; these goals are obtained by grafting. The eggplants are plants that can be grafted onto different rootstocks. The grafted seedlings transmit to crops quality, productivity, resistance to pests and diseases from soil, tolerance to abiotic stress factors, optimal absorption of water and nutrients, vigour. The study was conducted in a greenhouse of the Horting Institute Bucharest and it has followed the rootstock influence on the production quality at some grafted eggplants. The biological material has consisted of import F1 hybrids, eggplant scions (''Black Pearl’’ and ''Classic’’) and rootstocks (''Emperador’’ and ''Torpedo’’) commonly used in Romania for grafting of eggplants. It were determined form index (FI), form (F), weight/fruit (W), marketable production (MP), humidity (H) – gravimetric method, soluble dry matter (SDM) by refractometry method using ABBE refractometer, total sugar (TS) by Bertrand method. The results show that the grafting had influenced some aspects of the eggplant production. The conclusions of the researchers from the Horting Institute are in respect with some conclusions of the foreign researchers, but more researches are required in this domain to highlight the grafting effect on some aspects concerning production of grafted vegetables.
