Research regarding the behaviour of grafted eggplants to biotic and abiotic factors in crops in greenhouse

Abstract

Areas cultivated with eggplants occupy a very large surface in greenhouses and greenhouses, after tomatoes, peppers and cucumbers. The rootstocks assure to the eggplants high productivity, high quality of fruits and resistance/ tolerance to diseases and pests. The biological material was represented by eggplant cultivars Luiza and Aragon F1 and rootstock Torvum vigor. The purpose of the experience was to study the rootstock's influence on the growth, fructification and resistance to pathogens and pests of grafted eggplants.Eggplant plants grafted on Torvum vigor had a 19.8%higher vigor than Luiza and 25.2% Aragon F1 non-grafted. The yield was higher in grafted plants with 18.5% to Luiza cultivar and 17.8% to Aragon F1 compared with non-graftedvariant. The Torvum vigor rootstock gives to graftedplants a high resistance to the attack of soil pathogens Verticillium dahliae and Fusarium oxysporumf.sp. melongenae
