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.eninfo:eu-repo/semantics/closedAccessGerminationpollenPunica granatum L.viability22S23S-homobrassinolideArticle18222623010.1080/15538362.2018.1425652N/AWOS:0004329501000082-s2.0-85041104445Q1
