Comparative Ecology of Rubus Species (Rosaceae) II. Reproductive Characteristics of Three Rubus Species, R. palmatus var. coptophyllus, R. microphyllus and R. crataegifolius

Abstract The reproductive characteristics of three Rubus species ( R. palmatus Thunberg var. coptophyllus (A. Gray) O. Kuntze, R. microphyllus L.f., and R. crataegifolius Bunge) were critically investigated using materials collected from the forest floor of an 85-year-old Hinoki ( Chamaecyparis obtusa ) plantation in central Honshu, Japan. The underground branching patterns of these species were also investigated at the nursery. R. microphyllus produced the largest number of fruits in the same cane size among the three species (164 fruits per cane of 300 cm³ in D₀2H). However, the largest number of seeds produced per cane was in R. crataegifolius , where the maximum seed number attained 74,500 per cane, which was twice as many as those of the other two species. There was no apparent difference in dry matter allocation to fruits in these species. The three species produced numerous suckers by underground branching, forming large clones. In the open site at the nursery, the number of suckers produced by underground branching increased exponentially. On the other hand, in natural populations occurring in closed sites, the number of suckers produced by underground branching in the three species was by contrast much smaller. Three Rubus species proved to possess similar perennation as well as reproductive strategies, although R. palmatus var. coptophyllus shows much lower seed production and slower sucker production than the other two species.     

中国栘木衣属（Docynia Dcne.）一新种——长爪栘木衣

Comparative Ecology of Rubus Species (Rosaceae) I. Ecological Distribution and Life History Characteristics of Three Species, R. palmatus var. coptophyllus, R. microphyllus and R. crataegifolius

Abstract The ecological distribution and life history characteristics of three Rubus species, i.e., R. palmatus Thunb. var. coptophyllus (A. Gray) O. Kuntze, R. microphyllus L.f. and R. crataegifolius Bunge were investigated, with particular emphasis on the seasonal growth cycles, modes of the alternation of aerial organs, and patterns of dry matter allocation, and these features were critically compared with one another. It was found that seasonal changes of aboveground biomass are strongly related to the modes of cane alternation, to underground branching producing stolons, and to their dry matter allocation patterns. The modes of cane alternation, underground branching and dry matter allocation patterns were very similar in R. microphyllus and R. crataegifolius , taking about five months from May to September. But R. palmatus var. coptophyllus showed much more gradual replacement of aerial organs, extending over seven months from May to December. These three Rubus species are often predominant in the early successional stages of pioneer communities which develop after cutting of forests in central Japan, and differentiations of the above-mentioned life history traits found in Rubus species seem to be related to the constraints inherent in their somewhat labile, changing environments, e.g., at the forest margin or clearings produced temporarily.
