Vegetable grafting as a research topic in Croatia

Grafting is a common practice in watermelon field cropping with the purpose of environmental stressors mitigation. This technique is not widespread in other vegetable species, although there are some occasional good examples in tomato or cucumber greenhouse cropping, but based on seedlings import. In our previously researches, the role of rootstocks on mitigation of biotic and abiotic stressors in cucurbits were studied. Thus in the trials on grafted cucumber in soil infested with root-knot nematodes, vegetative growth and yield of the plants grafted on the interspecific hybrid rootstocks, Strong Tosa and RS 841 Improved, were the highest. Based on the study in watermelon, rootstock Strong Tosa was selected in withstand of salt stress probably due to the ability to induce anatomical adaptation and superoxide dismutase activity in response to salt stress. During the current study, the effect of grafting and nitrogen rate on yield and aerial pests populations has been studied in hydroponics tomato. Tomato yield was not affected by rootstock Arnold, while population density of Bemisia tabaci and Tuta absoluta was lower on grafted plants. The study has been continued, composition of amino acids in phloem sap, and fruit quality of grafted and ungrafted plants will be analysed.
