A Comparative Study of Floral Traits between Meizhou Cerasus campanulata and Taiwan Prunus cerasus

The floral traits including floral morphology,floral color and pollen viability among the Cerasus campanulata which grow naturally in Meizhou Mingshan Mountain and Prunus cerasus including Prunus campanulata,Prunus lannesiana and C.yedoensis which were introduced from Taiwan and planting in cherry garden of Mingshan Mountain were investigated.The results showed that the Meizhou Cerasus campanulata pedicel was shorter and its petal was smaller than Taiwan Prunus cerasus.The calyx was longer than that of Prunus campanulata and Prunus lannesiana,but significantly shorter than that of C.yedoensis.However,the flowers were shorter than that of C.yedoensis but longer than that of Prunus lannesiana.The color of calyx,petal,filaments and style was diverse and varied with different degrees.There was no difference of pollen viability between Meizhou Cerasus campanulata,Prunus campanulata and C.yedoensis,while the pollen viability of Prunus lannesiana was lower markedly than that of Meizhou Cerasus campanulata(p0.01) and Prunus campanulata(p0.05).
