Abstract: BACKGROUND AND OBJECTIVE: Tomato (Solanum lycopersicum L.) is widely cultivated and consumed in many countries around the world, including Vietnam. Cytokinin (CK) is a plant hormone that plays a crucial role in numerous plant growth and developmental processes. A study was carried out to analyze the impacts of 6-benzyl adenine (6-BA, a type of CK) on some physiological and biochemical parameters of tomato varieties at the 5-leaf stage and the flowering stage cultivated in Thanh Hoa province, Vietnam. MATERIALS AND METHODS: The experiments consisted of two factors (6-BA concentration and tomato variety) arranged in a Split Plot design with three replications, in which the concentration of 6-BA (0 (control), 6 and 12 mg L-1) was the whole-plot factor and the tomato variety (P375, CS1, Pn and F) was the split-plot factor. RESULTS: The results showed that indicators including plant height, dry matter content, chlorophyll a content, chlorophyll b content, total chlorophyll content, carotenoid content, vitamin C content, total organic acid content, catalase enzyme activity and peroxidase enzyme activity of tomato varieties treated with 6-BA at a concentration of 6 and 12 mg L-1 were higher than those of the control group. The study also showed that impacts of 6-BA on tomato physiological and biochemical parameters depend not only on the concentration of 6-BA but also on the developmental stages and plant varieties. CONCLUSION: In general, CK has markedly influenced the physiological and biochemical parameters of tomato varieties. These results provide some insights into the role of CK in tomato growth and development.
