초록
The microstructure observation of seed surface structure is needed for protocols of breakingdormancy of seeds with physical dormancy. The seeds of Rubus species are surrounded by athick, hard endocarp; together, the seed and endocarp make up the stone. We evaluate stonecharacteristics of 18 species of Rubus through optical microscopic observation, and correlatedifferent stone characteristics with endocarp thickness. As a result of stone size comparison,Rubus species were classified as big stones group including R. parvifolius and R. idaeus, smallstones group including R. longisepalus var. longisepalus, R. corchorifolius and R. hirsutus, andmiddle stones group including rest of the species. The result of this study revealed that stonesize and the endocarp thickness in Rubus species was various characteristics in each species. Furthermore stone size and stone weight were also well correlated endocarp thickness and resultindicated that heavy stones had harder endocarp than lighter one. Thus from the result of thisstudy it can be presumed that only one stone characteristic approach may be sufficient toestimate other characteristics in Rubus.
Abstract
The microstructure observation of seed surface structure is needed for protocols of breakingdormancy of seeds with physical dormancy. The seeds of Rubus species are surrounded by athick, hard endocarp; together, the seed and endocarp make up the stone.

As a result of stone size comparison,Rubus species were classified as big stones group including R. parvifolius and R. idaeus, smallstones group including R. longisepalus var. longisepalus, R. corchorifolius and R. hirsutus, andmiddle stones group including rest of the species. The result of this study revealed that stonesize and the endocarp thickness in Rubus species was various characteristics in each species. Furthermore stone size and stone weight were also well correlated endocarp thickness and resultindicated that heavy stones had harder endocarp than lighter one. Thus from the result of thisstudy it can be presumed that only one stone characteristic approach may be sufficient toestimate other characteristics in Rubus.
