Four tomato cultivars Macarena F₁, Faustine F₁, Cathy F₁ and Fanny F₁ were used in the study. Transplants were grown in a greenhouse. Seeds were sown at the end of March. The plants were grafted on Maxifort F₁ rootstock on April 5, 6 and 21 in the years 2006, 2007, 2008 without the use of biostimulators. In the case of the other combinations each year the following treatments with biostimulators were performed: watering with Goteo 0.1% solution (twice – 4 and 2 weeks before planting and three times after planting at three-week intervals), spraying with BM 86 0.1% solution (four times every three weeks starting at the blooming of the first cluster). In the control combination plants were untreated with biostimulators and were not grafted. Physical properties were determined and sensory analysis of tomato fruit was performed. The results showed that there was no significant influence of the applied preparations on the a*/b* value of fruits which depended mostly on the cultivars. The highest fruit firmness was obtained with BM preparation and in Faustine F₁ and Cathy F₁ cultivars. There was no significant influence of the preparations on sensory quality of fruits. Variability in sensory quality of fruits rather depended on the analyzed cultivars than on the investigated combination.
