Abstract

The effects of hormonal treatment for fruit setting of tomato (Solanum lycopersicum L. var. Super-Yubi) on the development of a small hole at the blossom end of fruit were investigated. Tomato plants were cultured hydroponically using Enshi solution at half strength. Flowers were sprayed with chloxyfonac (HCPA:49ppm and 196ppm) with GA_3 (0 or 15ppm) at anthesis. There was a high rate of hole formation after treatment with HCPA 49ppm+GA_3 15ppm. A hole on the top of the ovary was detected two weeks after anthesis. Histological examination demonstrated that a narrow channel extending to the locule was present just under the style 1 week after anthesis and split opened forming a hole on the top of the fruit 2 weeks after anthesis. Style split and corky tissue at the blossom end induced by cracking of the exocarp were also observed after treatment of HCPA 49ppm+GA_3 15ppm.
