Control of Physiological Fruit Drop of Japanese Persimon ′Hiratanenashi′

The study was conducted to clarify the effects of indolebutyric acid (IBA) tape and brassinolide (BR) on fruit abscission and fruit quality of Japanese persimmon ′Hiratanenashi′.1. Application of IBA tape containing 0.1% IBA to fruit apex at 10 days after flowering reduced fruit abscission.2. Spray of 0.1ppm BR on flower at 3 days prior to flowering reduced fruit abscission. Endogenous indoleacetic acid in flesh increased with the treatment of BR.3. Quality of fruits treated by IBA tape or BR was similar to that of control (no treatment).
