Information on germination characteristics is necessary when introducing wild flowers to green areas. Therefore, the characteristics of nine wildflowers were investigated in laboratory experiments using petri dishes. The germination characteristics of a total of sixteen wildflowers that were used in the present and previous papers were classified as follows:<BR>1. Classification with respect to the range of constant temperature for good germination under light.<BR>a) Low temperature (10-15°C): Rannunculus japonicus.<BR>b) Middle temperature (15-25°C): Ixeris dentata., Cirsium japonicum. and five others.<BR>c) High temperature (25-30°C) Solidago virgaurea. subsp. asiatica. and three others.<BR>d) Wide range of temperature (10-30°C): Aster ageratoides subsp. ovatus., Lotus corniculatus var. japonicus. and five others.<BR>e) Low germination under any constant temperature: Anthriscus sylvestris subsp. aemula. and Potentilla kleiniana subsp. anemonefolia<BR>2. Classification with respect to the effect of light on germination.<BR>a) Good germination occurred under light, whereas low germination occurred in the dark: Ixeris dentata., Cirsium japonicum. and three others.<BR>b) Good germination occurred even in the dark. This was restricted to a narrow range of temperatures and the germination was lower than that of under light: Ixeris stolonifera, Picris hieracioides subsp. japonica. and seven others.<BR>c) Germination was higher in the dark than under light: Rannunculus iaponicus.<BR>d) Much difference in germination was not observed between light and dark conditions: Lotus corniculatus var. japonicus.<BR>e) Low germination under any of the above conditions: Potentilla kleiniana subsp. anemonefolia. and Anthriscus sylvestris subsp. aemula. In most species, stratification at 3°C caused an increase in germination percentages and an expansion of the range of temperature for good germination under light or dark conditions. Seeds stored at 3°C and under dry conditions kept their initial germination ability for at least six months.
