Both vegetative and preproductive growth of tomato (Lycopersicon esculentum L. var Wosowoso) were influenced by the application of cultar (100 ppm) and triadimefon (200 ppm). The fresh and dry weights of leaves, stems and roots were significantly (P0.05) decreased by the chemicals and the elongation of the stem was significantly (P0.05).) retarded. The expansion of the epidermal and palisade cells and leaf area were significantly (P0.05) reduced. Although, eultar and triadimefon had no effect on the number of stomates at the adaxial surface of the leaves, the size of the stomatal aperture was decreased significantly (P0.05). The chemicals increased chlorophyll and carotenoid levels in the leaves compared to the controls. The levels of total soluble carbohydrates and relative water content in the leaves also were increased significantly (P0.05). Although cultar and triadimefon delayed the onset of flowering, the number of flowers per plant in the chemically:treated plants was significantly (P0.05) higher than in the control plants. Yield in tomato was also significantly (P0.05) increased by cultar
