Recently, the replanting of roof and wall surface of many buildings is advanced by using Sedum, from the viewpoint of environmental improvement or phytoremediation. Sedum is the plant which does "Crassulacean Acid Metabolism". The Sedum is strong succulent plants which can grow even in slight soil dried place and crack in the rock mass. However, Sedum has also indicated that it does not correspond with having Japanese climate of the season with much rain. By the present, the quantitative relation on cultivation condition and growth situation of Sedum is not completely clear. For the development of the convenient and effective replanting method using Sedum, established of the quantitative diagnostic method of growing condition is necessary. In this study, glucose and abscisic acid production was monitored under the open-field culture conditions over time. It became clear that the content of the glucose relevantly increased in the color in the winter than that of the autumn. The analysis under the drying condition and open-field culture condition was carried out on the Sedum pallidum. The abscisic acid was detected from the result of cultivating under drying condition. And, the increase in multiple organic compounds was confirmed in the extract from the sample under the drying condition. It is considered that these components are the organic acid component.
