噴蠟對海梨柑與無子桶柑蒸散速率與果實品質之影響

Effect of Wax on Transpiration Rate and Fruit Quality of 'Hai-li' Tangor (Citrus tankan Hay. cv. Hai-li) and 'Seedless Tankan' Tangor (Citrus tankan Hay.)

使用三種屬於液蠟的薄膜形成型蒸散抑制劑及一種界面活性劑於‘海梨桶柑’之葉片上，結果顯示協養旺－－207蒸散抑制效果之時間較長。再於九月與十月以協養旺－－207之100倍稀釋液分別處理盆栽之‘無子桶柑’及‘海梨柑’之果實與葉片，發現除了九月份的‘無子桶柑’葉片外，其他處理之蒸散速率均降低，但僅有九月份‘海梨柑’之處理者，達到差異顯著水準。九至十一月每月對田間‘海梨桶柑’噴施協養望－－207水溶液，結果均能降低葉片蒸散速率，但僅有十月處理者，達到差異顯著水準。噴蠟處理後之果實酸度明顯較高，果實略小於對照組，果汁率與含水量則略高，但後三者均未達差異顯著水準。

After applying three kinds of liquid wax based antitranspirant and one surfactant upon Hai-li Tangor leaves, the results showed that Abion-207 achieved the best anti-transpirant rate. Except for the seedless Tankan leaves treated in September, all other seedless and Hai-li Tangor leaves and fruits applied with Abion-207 dilated 100 times with water had their transpirant rate significant reduced. In field experiment, the applications of Hai-li Tangor with Abion-207 liquid solvent all resulted in a lower transpirant rate of leaves, however, only those treated in October show a significant decrease. Because of the varying degree of environmental differences, the statistic analysis was based on the exchange of the relative percentage of each individual area into angles- degrees. The outcome shows that the treatment of wax spray can significantly reduce Hai-li Tangor's transpirant rate. After treatment, the fruits exhibited signs of higher acidity and while the juice and water content were significantly higher, the fruit-size is reduced.
