Obtaining of Grafted Planting Material at Some Romanian Tomatoes

Abstract

The tomatoes have highest share in Romanian crops from protected spaces (greenhouses, solariums). The grafting is an agronomical technique that induces or improves some qualities of the tomato cultivars (resistance to soil diseases and pests, resistance to abiotic factors, quantity and quality of fruit production). The research was aimed the establishing of the technological stages for producing of scion and rootstock seedlings from L. esculentum species, to obtain compatible phenotype when is grafted. The observations of this research were conducted on Department of Horticultural Cultures in Protected Spaces from Horting Institute Bucharest. The experience was carry out on a cultivar collection consisting from L. esculentum plants: scions (‘Siriana’–F1 hybrid and ‘Buzău 1600’– variety), creations from the germplasm bank of Research and Development Station for Vegetable Growing Buzău Romania (VDRS Buzău) and rootstock (‘Groundforce’–F1 hybrid). The plant diameters were correlated for a grafting by the annexation method, cutting at 45 degrees. The grafting was performed successfully. The technological steps have achieved phenotypic compatibility of the symbiotes when was the grafting by annexation. The technology for producing of scion and rootstock seedlings at these Romanian tomatoes (‘Siriana’ and ‘Buzău’ 1600) was established for the crops in protected spaces in south area of Romania.
