摘要

台灣蓮霧栽培面積約有八千公煩，主產區分佈於屏東縣與高雄縣。高屏地區冬少雨，日照充足以及較少颱風的威脅，砲褆高品質蓮霧的生彥季節，但近年來蓮霧採收時出現裂果的問題日益嚴重，造成果實商品價值下降，導致價格滑落；此外，開裂的傷口易遭受植物病原菌與腐生菌感染，極不利於果實的保存及運輸。本試驗的目的在於嘗試利用CH100 植物健素預防蓮霧裂果與落果的問題，祈能提昇農民的收益。第一次試驗在屏東縣林邊鄉進行，時間自民國九十年六月至九十一年六月；第二次試驗在屏東縣南州鄉進行，時間自民國九十一年三月至九十一年十二月。從蓮霧花苞期開始施用CH100 植物健素1,000倍稀釋，每兩個星期葉面噴灑一次，直到採收前兩星期為止。試驗結果顯示，冬季施用CH100植物健素的蓮霧果實，裂果率及落果率明顯低於對照處理；在夏季，CH100植物健素亦具有減緩蓮霧出現裂果及落果的效果。

Waxapple (Syzygium samarangense Merr. & Perry) is a high-value tropical fruit crop in Taiwan. The production of this crop is often encountered with the problems of fruit dropping and fruit cracking, resulting in poor quality and low yield. Experiments were conducted in two commercial fields in southern Taiwan to determine effects of CH100, a formulated plant extract, on fruit dropping and fruit cracking of waxapple. CH100 at 1000 ppm was sprayed on waxapple trees bi-weekly, from blossom to fruit ripening period. Results of the two field trials showed that the treatment of waxapple trees with CH100 significantly(p＜0.05) reduced fruit dropping and fruit cracking grates and increased single fruit weight and fruit sweetness. For example, in the experiment I, the fruit cracking, fruit dropping, single fruit weight and fruit sweetness were, respectively, 15.0%, 9.8%, 128 gram and 11.6 Brix for the treatment of CH100, compared to 39.8%, 23.6%, 108 gram and 9.2 Brix for the control (water).
