우리나라에서 栽培되고 있는 사과品種中 Tsugaru, Jonagold 및 Fuji 品種을 供試하여, 摘果劑로 알려진 carbaryl의 摘果效果와, 摘果作業의 省力化를 위한 藥劑摘果의 실용성을 검토할 目的으로 遂行하였다. Tsugaru, Jonagold 및 Fuji 品種에서 carbaryl 의 摘果效果는 이들 三品種에서 認定되었고, carbaryl 撒布時期는 Tsugaru 品種 5月 17日, Jonagold 및 Fuji 品種은 各各 5月 13日 및 5月 15日로 나타났다. carbaryl 撒布時 果徑에 따른 落果는 Tsugaru, ...

Tsugaru, Jonagold 및 Fuji 品種에서 carbaryl 의 摘果效果는 이들 三品種에서 認定되었고, carbaryl 撒布時期는 Tsugaru 品種 5月 17日, Jonagold 및 Fuji 品種은 各各 5月 13日 및 5月 15日로 나타났다. carbaryl 撒布時 果徑에 따른 落果는 Tsugaru, Jonagold 및 Fuji 品種에서 果徑이 各各 11.6, 12.0mm및 6.8mm 以下에서 100 % 낙과되었고 果徑이 各各 15.0, 16.0mm 및 9.0mm 以上에서 낙과율은 감소하는 경향을 보였다. carbaryl 撒布時 果徑에 따른 落果反應은 Jonagold 品種이 Tsugaru, Fuji 品種 보다 강하게 나타났다. 藥劑撒布에 따른 ethylene 生成은 Tsugaru 品種에서 증가하는 경향을 보였으나, Fuji 品種에서는 ethylene 生成 증가없이 落果되는 경향을 보여 주므로써, ethylene 이 落果에 미치는 영향은 相異하게 나타났다.

This experiment was conducted to determine the optimum spraying time as affected by carbaryl spraying on thinning in Tsugaru, Jonagold and Fuji cultivars. The results obtained are as follows; 1. The most effective spraying time of carbaryl was determined on May 17 in Tsugaru, May 13 in Jonagold and May 15 in Fuji. 2. The fruit thinning as influenced by carbaryl spraying was 100 percent when the central fruit diameter was below 11.6 mm in Tsugaru, 12.0 mm in Jonagold and 6.8 mm in Fuji, but carbaryl spraying was decreased fruit thinning when the central fruit diameter was bigger than 15.0 mm in Tsugaru, 16.0tnm in Jonagold and 9.0mm in Fuji cultivars. 3. Fruit thinning as influenced by carbaryl spraying was the most sensitive by fruit diameter in Jonagold among cultivars treated. 4. Ethylene evolution after carbaryl spraying was increased in cultivar `Tsugaru' while no change was observed in cultivar 'Fuji'.
