EFFECT OF DIFFERENT BORON LEVELS ON POLLEN GERMINATION OF HICAZ NAR POMEGRANATE ( Punica granatum L.) CULTIVAR

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.
