| Abstract: | Three different types of epicuticular wax columns were foundinBrassicaspecies with a chromosome number (n)=9: long columns(LC), short columns (SC) and netted columns (NC). LC were foundinB. incanaandB. rupestris.SC were found inB. villosa, B. macrocarpa,B. cretica, B. hilarionisand also inB. montana. B. insulariscolumnswere intermediate. NC waxes were found inB. oleraceaand itsclose alliesB. alboglabraandB. bourgeaui.Samples ofB. rapa (n=10)andB.nigra (n=8)examined did not show any wax columns but their amphidiploidswithB. oleracea (B. napusandB. carinata,respectively) seemedto inherit the NC type of wax present inB. oleracea.Copyright1999 Annals of Botany Company Brassica, waxes, wax columns, leaf surface. |
