Establishment of Technological Stages for Obtaining Some Grafted Tomato Seedlings (Dutch Scion × Romanian Rootstocks)

Dorin SORA

Abstract


The tomatoes are valuable vegetables, with highest share in Romanian crops from protected spaces. The grafting is a vegetative multiplication method that induces or improves some qualities of the plants (vigor, resistance to soil diseases and pests, resistance to abiotic factors, quantity and quality of fruit production). The research aim has been to establish the technological stages for producing of Dutch scion and Romanian rootstock seedlings from Solanum lycopersicum L. species, to obtain some compatible phenotypes for grafting. This research has been conducted in a greenhouse of the Horting Institute Bucharest. The experience was carried out on a tomato cultivar collection consisting from a Dutch scion (‘Abellus’ F1 hybrid) and three Romanian rootstocks (‘L542’, ‘L543’, ‘L544’). The scion and rootstock diameters have been correlated for manual grafting, cutting at 45 degrees and using the method of splice in silicone tube. The technological stages for obtaining grafted tomatoes have been established for the researched genotypes. These tomato combinations have been compatible for vegetable crops in protected spaces in the south area of Romania.
