Abstract
Forcing flower is an important step for planting pineapple. Although many papers have been reported about forcing flower for pineapple plants on the aim of harvesting fruits, no reports have been found about forcing flower at seedling phase for preparing bonsai. In this paper, Tainong 4, Tainong 16 and Tainong 17 plants with 20 leaves were watered on stem apex with 40 ml of 0.13% of ethephron . Results showed that most of Tainong 4 plants flowered after being treated 30 days. None plant of Tainong 16 flowered after being treated 60 days. In the same variety, for example, Tainong 4, some plants flowered earlier, some plants flowered late. Tainong 4 was the most sensitive to ethephron at early-growth phase. Tainong 16 was the most insensitive variety. The low flower rate in this research might be due to that the pineapple plants were in early-vegetative-growth stage. They had not appropriate physiologi cal conditions for forcing flowers. For making pineapple bonsai at early-vegetative-growth phase, higher doses of forcing-flower agent should be used than those of forcing-flower agent for harvesting fruits.
