Studies of Flowering Character of 'Hui Sun'(Pyrus koehnei) Pear

By 邱明賜, 倪正柱, Min-Syh Chiou and Cheng-Chu Nee


The number of flower from single bud of 'Hui Sun' was 8 to 9 and the percentage of flowering uniformity was 91%±4 at lowland in Taiwan with very little chilling. For different circumstances of pollen germination, the rates of pollen germination were 46%, 43%, 44% and 51% when cultured in 30℃, pH5.5, 1% agar and 15% sucrose, respectively.The fruit could be obtained from the hybridization of 'Hui Sun' pear and pollen parent 'Hui Sun' pear.臺灣野梨單芽開花數平均為8~9朵,於低海拔開花整齊度為91±4%。花粉發芽環境,溫度30℃時有46%之發芽率,pH值於5.5時有43%之發芽率,洋菜濃度1%時有44%之發芽率,蔗糖濃度15%時有51%之發芽率。利用台灣野梨之花粉授粉於豐水梨,可獲得果實
