摘要

The seed coat ultrastructural morphology of seed accessions of 10 subgenera of Rubus preserved at the US Department of Agriculture, Agricultural Research Service, National Clonal Germplasm Repository, Corvallis, Oregon, USA, using scanning electron microscopy (SEM). SEM images were taken for 56 seed samples collected worldwide. The macromorphological characteristics differed among the groups at the subgenus level. Chamaemorus, Cyclactis (except R. saxatilis), Idaeobatus, Lampobatus, Malachobatus and Michranthobatus had similar exomorphic patterns. R. odoratus and R. parviflorus had a unique hilar end hole. R. saxatilis had seed coat sculpturing inconsistent with its assigned subgenus (Cyclactis) and appeared more in common with subgenus Idaeobatus. Rubus and Idaeobatus subgenera showed conspicuous patterns of reticulate and rugose surface relief of the outer cell walls. Species belonging to the Rubus subgenus had steeper-edged truncate or acute lateral ridges with a wide and protruded raphal region, while Idaeobatus had smoothly curved rounded ridges and raphal region. The two species in subgenus Chamaemorus showed articulate, finely textured surface with flat or no secondary cell wall protrusion and a ridged raphe. For R. arcticus subgenus Cyclactis, accessions from three geographical regions, had consistent microsculpture patterns. These morphological characteristics of Rubus seed revealed by SEM provide additional information to identify infrageneric levels.
