Determination of Germination Capability of Pollen in Different Flower Types in Some Pomegranate Varieties

In the pomegranate trees, there are hermaphroditic bisexual flowers and functionally male flowers. In some cases, intermediate forms are seen in pomegranate trees according to environmental factors and growing conditions. One of the most important factors affecting the fertility is the hermaphroditic bisexual flowers and functionally male flowers that ability of the germination capability of pollen. This study was carried out with the ‘Mayho？ 8’, ‘Kat？rba？？’, ‘Yufkakabuk’ and ‘A？？nar’ varieties in the pomegranate orchard in the Dardanos Campus of ？anakkale Onsekiz Mart University in order to determine the germination capability of different flower types. Four different pomegranate varieties of hermaphroditic bisexual flowers, functionally male flowers and intermediate form of flowers pollen germination ratios were determined. The germination of the pollens in three types of flowers was determined by agar-petri method under in vitro condition. The germination ability of the pollens in four cultivars and the germination ratios of the three flowers types were compared. It was determined that the there was no significant difference in the germination average between varieties. The average germination rate of ‘Mayho？ 8’ was the highest with %20,8. It was determined that functionally male flowers had more germination ability than intermediate form and hermaphroditic bisexsual flowers. It was determined that germination rates of functionally male flowers were insufficient for fruit set
