| Abstract:
We examined the germination pattern of 47 indigenous and cultivated species of Rubus for three years (n=230 samples). 100 days after sowing, we classified the germination pattern into four types: best germinated (10 spp.), better germinated (7 spp.), hardly germinated (7 spp.) and not germinated (23 spp.) type. The best germinated species are subtropical or warm temperate dwellers with evergreen leaves, and for many, their fruits mature in autumn to winter. In contrast, the hardly or not germinated species, mainly inhabit deciduous forest with clear seasonality, suggesting a strategy to make a seed bank under the soil in response to fluctuating climate conditions. | |
