Vegetative Propagation in Dilophus okamurae and Zonaria flabellata (Dictyotaceae, Phaeophyta)
Results of the present writer's observations on vegetative propagation in Dilophus okanmurae Dawson and Zonaria flabellata (Okamura) Papenfuss (Dictyotaceae, Phaeophyta) are presented in this report.
Vegetative propagation in Dilophus okamurae occurred on the blade margins and surfaces as well as at damaged portions. Proliferous branch initials for vegetative propagation developed into sparsely dichotomously branched subcylindrical to compressed stoloniferous branches which later terminally produced a dichotomously branched erect blade. Vegetative propagation in this species was detected to occur also in the vicinity of the Oki Islands during autumnal season extending from September to November.
In Zonaria flabellata vegetative propagation occurred on the primary rhizoids. Uniserial proliferous branch initials for vegetative propagation developed into biserial cylindrical erect branches which underwent apical growth with a single apical cell. The biserial developed erect branch terminally produced a fan-shaped blade which underwent meristematic marginal growth.
