dc.description.abstractEvaluation of pollen viability and its germination capacity are essential criteria for pollinator's characterization. Hormones have been used to increase yield and quality of pomegranates without any reference to effects on pollen viability or germination. With this point of view, effects of field-applied 22S, 23S-homobrassinolide (HBR) after bud break at concentrations of 0.001, 0.01, and 0.1 mg L-1 were evaluated on pollen quality of Mayhos-8 pomegranate cultivar. After collection of the flowers of both sexual morphs (bisexual and functionally male), colori-metric test of 2,3,5-triphenyl tetrazolium chloride (1%) were used to estimate pollen viability. Later, pollen germination was determined in vitro on a medium containing 1% agar and 20% sucrose. Results showed that pollen viability was under the influence of both the types of the flower and the concentration of the HBR. The highest pollen viability (96%) was obtained from both functional male and bisexual flowers treated with 0.1 mg L-1 HBR. Germination ratio, on the other hand, was only affected by the hormone concentrations, and it increased significantly as the concentration was higher.
