Arnold Arboretum Announces Deland Award Recipients

"Mariana Oliveira e Castro is working on her master’s thesis in the Department of Life Sciences at the University of Coimbra in Portugal under the supervision of João Carlos Mano Castro Loureiro. In collaboration with John and Sally Perkins of the American Rhododendron Society, Mariana will determine the ploidy level (number of chromosome pairs) of 50 specimens of Rhododendron calendulaceum held in the Arboretum’s living collection. R. calendulaceum, a tetraploid, shares many characteristics with the diploid species R. cumberlandense. Ploidy level analysis will help to clarify the classification of Rhododendron species present in the collection."
