Pollen morphology investigations of three Buddleja L. (Scrophulariaceae) taxa used in landscaping of parks and gardens from Eskisehir province

Abstract

In this study, pollen morphology of three Buddleja davidii cultivars (B. davidii Franch cv. monum, B. davidii Franch cv. royal red and B. davidii Franch cv. white profusion) from Scrophulariaceae, which are used for landscaping in Eskişehir province, were investigated by light and scanning electron microscopy. Pollen grains of investigated cultivars are tricolporatae/tetracolporatae type and sphaeroidal shaped. Exine was seen to be tectatae-psilate-perforatae ornamentation. As a result of microscopic examinations, the distinctions between taxa were revealed statistically. Comparisons between studied taxa will contribute to taxonomy for classification of Buddleja davidii taxa.
