Research Abstract

I studied the effects of interaction between closely related Phyllodoce species and bumblebee pollinators on the evolution of plant mating systems. Phyllodoce aleutica, P. nipponica, and the hybrid coexist in Tateyama Mts., central Japan. Phyllodoce nipponica is much less dominant than R aleutica in Tateyama Mts. Therefore we expected that P. nipponica in Tateyama Mts. suffered from severe pollination competition. In contrast, only P. nipponica grow in Mt. Akaishi, western Japan. I discussed 1) whether the mating system of P. nipponica in Tateyama Mts. evolved to avoid the pollination competition? 2) is it possible to infer the production process of the hybrids in Tateyama Mts.? Fruit set of P nipponica was high in both Mt Tateyama and Mt Akaishi, and no significant difference was detected between the mountains. This indicated that R nipponica was self-compatible in both mountains. Phyllodoce nipponica could set fruits by R aleutica pollen in Tateyama Mts. Phyllodoce aleutica scarcely received bumblebees visitation by interspecific movement, however, most of bumblebees that visited on R nipponica was moved from R aleutica. These suggested that the hybrids in Tateyama Mts. might be produced by crossing P. aleutica pollen to R nipponica. I summarized that mating systems of R nipponica did not evolve by pollination interaction with R aleutica. High selfing ability of R nipponica was not caused by pollination competition with R aleutica, but might be derived from inherent low attractiveness. A lack of heterospecific-incompatibility to P. aleutica pollen in P. nipponica should accelerate the production of the hybrids.
