Abstract :In this study, it was aimed to determine the effect of different boron doses on pollen germination rates in in vitro conditions of Hicaz Nar  pomegranate cultivar at full yield.The A and B type of pollens collected separately from the pomegranate trees, were germinated by the `agar petri` method. Four different boron doses containing 1% agar, 15% sucrose and 0, 10, 20 and 30 mg/l ⁻ ¹ boric acid were used as a germination medium. It was determined that the pollen of both types of flower had the highest germination rate at 10 mg/l ⁻ ¹ boron application, and these rates were 62.17% in A type flowers and 41.87% in B type flowers. It has been observed that germination rates of flower pollen of both types of flower increased significantly in comparison with control with boron applications.
