Description
Stepwise multiple regression analyses were used in the aims to correlate statistically the geographic patterns in the abundance of½, C4 and CAM type grasses with patterns in climatic variables. The dominant grasses having the C3 , C4 and CAM pathways of photosynthesis were computed for the importance values of all the grass floras in 258 widely spaced regions of South Korea. From long-term climatic records, seasonal and annual values for solar irradiance, water supply, heat availability and combinations of these variables were assigned to each of 258 regions. The results of the analyses suggest that high humidity such as river sides and bottom of plant canopies have the strongest correlation with the importance value of C grass species in a regional grass flora, and that high minimum temperatures during the growing season have the strongest correlation with the importance value of C4 grass species.
According to the results of this study, C3 and C4 type grass distribution in South Korea had a strong correlation with the habitats of the grass flora. The arid areas of all the open air spaces and seasides were in the strongest correlation with C4 type grasses and facultative CAM in succulent of C4 type herbaceous species, while the grass flora of humid areas was in the stronger correlation with C3 type herbaceous species.
