Outline of Final Research Achievements

The environment including all the nonliving factors affects the living of plants, and some abiotic factors by itself can determine if an plant survives in a particular environment. Of these, the area along rivers and streams is one of particular environments and previous studies was reported that the ecotype of Adenophora triphylla var. japonica (Campanulaceae) has narrow lanceolate or cuneate leaves in riverside environment. Therefore, morphological, anatomical and cultivated analyses were conducted to clarify the plasticity of leaf morphology among ecotypes of A. triphylla var. japonica. Comparative studies of morphology and anatomy were indicated that there was no significant difference of cell size of leaves between the cultivated and the control individuals of rheophytic ecotype of A. triphylla var. japonica, suggesting that rheophytic ecotype of this species had gained the genetic variation to change the cell size of leaves in order to adapt into the environment of river sides.
