| Abstract |
It has generally been assumed that, in tidal zone fucoids, high level species have thicker cell walls and, consequently, a lower desiccation rate than low level species. This turned out to be erroneous: the desiccation rate of high level species is not low at all, in spite of their thick cell walls.When comparing plants of the same species but growing in different environments, it was found that neither the emersion time nor the exposure to sun influences the cell wall thickness of the plants, but exposure to wave action does have such an influence: the more exposed the plant, the thicker the cell walls and the lower the desiccation rate. |
