| Abstract | ||
| Qualitative transplant production plays an important role in the qualitative and quantitative improvement of tomato fruit. Thus, a greenhouse experiment was conducted at the green house in Bushehr Province in 2013, to investigate the effect of tebuconazole and varieties on some morpho-physiological characteristics of transplants of tomato (Lycopersicum esculentum L.). The experimental design was factorial arranged in completely randomized design with three replications. Tebuconazole concentrations were (0, 0.25, 0.5, 0.75 and 1) (mM). Varieties were included Early Y, Furia, Calj N3, Sun 6189, Sun 6109. Seed planting was done in transplant flat. The trials were measured: stem length, stem diameter, length of internodes, number of auxiliary branches, root length, fresh and dry weight of root. Increasing concentrations of tebuconazole induced stem length reduction, so that the maximum and minimum stem length was 22 and 13.7 cm, respectively, from control treatment and tebuconazole spraying with concentration of 1mM. Results showed that tebuconazole can significantly affect on length of internodes and the maximum and minimum length of internodes were 3 and 1.6 cm for control treatment and 1 Mm of tebuconazole spraying. Tebuconazole application had significant effect on length, fresh and dry weight of root. No significant difference was observed in terms of stem diameter between Calj N3، Early Y and Sun 6189. Generally, results showed tebuconazole application had proper effects on some of vegetative growth traits of transplant of tomato. | ||
