Bell pepper has an important content of vitamins (C, A, E and B), minerals and sugar. It ranks the fourth place in Romania, after tomatoes, onions and cabbage. Grafted bell pepper crops from Romania obtain higher productions compared to nongrafted bell pepper crops. The objective of the paper has been to establish the effect of some Capsicum rootstocks on some Romanian and Dutch bell pepper cultivars obtained in 2019 in the greenhouse from HORTING Institute. The biological material consists of cultivars of Capsicum genus: two scions (Dutch ‘Menta’ F1 bell pepper and Romanian ‘Regal‘ bell pepper) and three rootstocks (Romanian ‘L11A’ and ‘L12S‘ bell peppers and Dutch first-generation ‘Foundation’ hybrid). Dutch ‘Menta’ bell pepper and Romanian ‘Regal‘ bell pepper are commonly cultivated in fields, greenhouses, and solariums. There were studies in 6 grafted plant variants and 2 non-grafted plant variants of 36000 plants/ha. Grafting has influenced the yield and quality of bell pepper fruits. Grafting has positively or negatively influenced fruit yield and the content of biochemical compounds in grafted crops. The results of this research require an extension of the intra and interspecific grafting of the bell pepper, respectively into different rootstocks for the Romanian bell pepper crops from greenhouses, solariums, and fields.
