【 摘 要 】

Growth and reproductive yield of Yabumame (Amphicarpaea edgeworthii Benth.), a geocarpic edible wild legume, were investigated by field experiments. In experiment 1, seedlings of subterranean seeds derived from a natural habitat were transplanted to the field at a hill space of 30 cm within a row and 45 cm interrow spacing with 3 levels of support poles. A significant difference was observed in the increasing rates in the number of main-stem leaves between the plants with and without support poles since the 30th day after germination, when spiral elongation of their main stems started. The yield of subterranean seeds was approximately 20 gm-2, but the total reproductive yield including aerial seeds was 40 g m-2 The latter had a highly positive correlation with the total number of leaves. However, the plants with over 120 leaves per m2 to produce more aerial seeds than subterranean seeds. In experiment 2, the growth of seedlings of aerial seeds (SA) was compared with that of subterranean seeds (SS). SA and SS were transplanted to a level field with 1 plant per 1 m2 During the vegetative growth, the increasing rates of main-stem leaves were SA=SS, but the specific growth rates in total number of leaves were SA
