- W1996983251 abstract "(Matt.) Liebl. acorns. We study the practical feasibility of discrimination between pedunculate oak (Quercus robur L.) and durmast oak (Quercus petraea (Matt.) Liebl.) using morphological parameters. 44 populations were sampled, during mast crop year 1984, mainly from West, South-West and Central France. Seven shape variables were measured on 100 acorns in each population : radii at different level along the acorn, total length, maximum width and position of this maximum width. Principal components analysis shows a net distinction between the two species, according to the distance between the maximum width and the apex, and, in a lesser extend, to the maximum width. Acorn shape is highly correlated with the percentage of auriculated leaves observed after plantation. The species index, based on acorn shape, permits identification of individual acorns with only 15% error. It remains to be tested for other years and areas." @default.
