The Effect of Brassinosteroid on Pollen Germination and Tube Growth in Three Dianthus Species

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.
