Sažetak
Grafting of tomato (Solanum lycopersicum L.) seedlings onto selected rootstocks is an effective tool that may enable the susceptible scion to control biotic and abiotic stressors and increase yield. In these cases, the scion can modify its morphological properties. Grafting of tomatoes has been recently introduced in the Croatian greenhouse production. The aim of this study was to analyse the influence of commercial tomato rootstocks on the vegetative characteristic of tomato plants using the hydroponic growth system. Cultivars Clarabella and Estatio were grown as non-grafted, self-grafted or grafted onto rootstock cultivars Arnold, Buffon, Emperador and Maxifort. The experiment was set up in a greenhouse at the Institute of Adriatic Crops and Karst Reclamation during the spring summer season by random block design with four replications. During the nine measurements conducted over 61 days after planting (DAP), cv. Clarabella had more leaves compared to cv. Estatio at 32d. Grafted plants had a higher number of leaves compared to the non-grafted plants in the initial stages of growth (until 19 DAP). The height of the plants was affected by the scion during a period of 61 DAP. Cultivar Clarabella was higher than cv. Estatio for all measurements. The influence of the rootstock on plant height was expressed until 39 DAP after that the scion entered in to the generative phase. Clarabella cultivar had a higher plant diameter in comparison to the cv. Estatio, especially at the initial stages after planting. Also, there was a positive influence of the rootstock on the diameter of the plants. Plants grafted onto rootstocks Emperdor and Maxifort had a higher diameter compared to non-grafted or self-grafted plants. During all measurements, cv. Clarabella had a higher stem diameter compared to cv. Estatio. Rootstock failed to improve the diameter of stem in grafted cultivar Estatio. Rootstocks have improved the vegetative growth parameters of commercial tomatoes such as number of leaves, height, plant diameter and stem diameter. Improved morphological properties of grafted plants can enable to better withstand different stress conditions and achieve higher yields.
