The outline of results obtained are as follows: 1) The time from visible buds (5 mm length) to flowering takes about 24 days. Flowering had two peaks, first on early April and second on middle April. However, the buds from May to December could not have developed into flowers. The time from the pollinated flower to the mature fruit takes about 60±4.9 days. 2) The different types of flowers had three peaks, the first from 1st to 3rd of December, a second peak from 5th to 7th of December, a third peak from 14th of December. 3) It was considered that the flowering depends on the air temperature in the morning. 4) The flowering percentages of the different type were: 87.3% for normal (contact) type, 8.1% for recreate type, and 4.5% for upright type. The highest fruit set percentage was observed in the normal and recreate type flower. Flowers with upright styles failed to set fruit. 5) The average fruit percentage was about 59-63% by hand pollination during two flowering period. Correlations did not exist between fruit set and air temperature or humidity. 6) The highest fruit set percentage showed 8 hours after flower open., 論文}, pages = {5--17}, title = {ハウス栽培パッションフルーツの栽培技術開発 第1報.開花習性と結実習性}, volume = {39}, year = {2005} }
