Size-dependent clonal reproduction and sex allocation in the monoecious Begonia emeiensis
Size-dependent clonal and sexual reproduction has been studied in many species. However, very few attempts have investigated size-dependent resource allocation among clonal reproduction, female function, and male function within a species. Moreover, how clonal reproduction and sexual reproduction interact to influence size-dependent sex allocation has not been explored. In this study, we investigated the size dependency of clonal reproduction and sex allocation and how clonal reproduction and sexual reproduction interact to influence size-dependent female function, male function, and sex allocation in the monoecious Begonia emeiensis. Individuals with no reproduction, reproducing clonally through bulbils, reproducing sexually through flowers, and reproducing through both bulbils and flowers differed significantly from each other in terms of size (leaf area), suggesting a threshold size for clonal versus sexual reproduction. Bulbil number per individual increased with size regardless of flower production. In contrast, the relationship between size and female and male flower production per individual was influenced by bulbil production; both female and male flower numbers per individual increased with size at a slower rate for individuals reproducing clonally and sexually than for those reproducing only sexually. The ratio of female to male flowers per individual increased with size independent of bulbil production. Our study shows that the size dependency of clonal reproduction was unlikely to be influenced by sexual reproduction; however, the size dependency of female and male function was influenced by clonal reproduction.
期刊介绍:
Plant Species Biology is published four times a year by The Society for the Study of Species Biology. Plant Species Biology publishes research manuscripts in the fields of population biology, pollination biology, evolutionary ecology, biosystematics, co-evolution, and any other related fields in biology. In addition to full length papers, the journal also includes short research papers as notes and comments. Invited articles may be accepted or occasion at the request of the Editorial Board. Manuscripts should contain new results of empirical and/or theoretical investigations concerning facts, processes, mechanisms or concepts of evolutionary as well as biological phenomena. Papers that are purely descriptive are not suitable for this journal. Notes & comments of the following contents will not be accepted for publication: Development of DNA markers. The journal is introducing ''Life history monographs of Japanese plant species''. The journal is dedicated to minimizing the time between submission, review and publication and to providing a high quality forum for original research in Plant Species Biology.
