Abstract :In this study, the effect of brassinosteroid on pollen germination and tube growth of Dianthus calocephalus , Dianthus carmelitarum, and Dianthus deltoides were investigated. Brassinosteroid treatment increased the germination rate in all species (except 0.05 mM in Dianthus carmelitarum and 2.5 mM in D. deltoides ). However, a significant increase was only observed in D. deltoides . The germination rate was highest after 0.25 mM BR treatment in D. calocephalus , while the germination rate was highest after 0.5 mM BR treatment in D. carmelitanum and D. deltoides . Brassinosteroid treatment increased the tube length in all species. However, a significant increase was only observed in D. calocephalus . Also, tube length was maximum after 0.25 mM BR treatment in D. calocephalus and D. carmelitarum , while tube length was maximum after 0.5 mM BR treatment in D. deltoides . Brassinosteroid treatment increased the tube abnormality rate (except 0.25 mM in D. deltoides ), insignificantly.Keywords : Brassinosteroid, Dianthus, Plant bioregulators, Pollen germination, Pollen tube growth
