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.
