Abstract
生育滿一年的台農四號鳳梨植株，於九月間催花處理，以促進提早生產春果，開花後在畦間搭建隧道式PE塑膠棚覆蓋，最高溫度在每日下午二點，全部覆蓋較不覆蓋對照處理者溫度昇高10.1℃，最低溫度在凌晨六點，全覆蓋較對照區降低1.9℃。PE塑膠棚全覆蓋略可提早果實成熟期，並顯著的增加果重及果實糖度與酸度，較對照區依次分別增加277.7公克及0.94。Brix與0.14%；惟糖酸比反而較對照區爲低，兩者相差1.64。但食用時口感上未有明顯差異。
One-year-old Tai-Nung No.4 pineapple plants were prompted to produce spring fruits by forcing treatment in September and sheltered by Ph-sheet tunnel on the furrow after flowering. The results showed the maximum average-temperature under the full covered Ph-sheet tunnel increase about 10.1℃ at P.M. 2:00 and the minimum average temperature decrease about 1.9℃ at AM. 6:00 in one day. The maturing stage was prompted and weight of fruit, brix and acidity were increased about 277.7g, 0.94. and 0.14%, respectively after sheltering. However, the ratio of brix/acidity decrease about 1.64. Therefore, it is not significantly different in sensory taste.
