Adaptation of Phragmites communis Trin. Population to Soil Salt Contents of Habitas
초록
The ecotypic variation of Phragmites communis Trin. was studied from Aug. 1989 to March 1992 in three populations of salt marsh, estuary and fresh water areas of the western coastal regions in Korea. The length growth and aboveground total dry weight of Phragmites communis Trin. From three habitates were measured monthly and the seeds from them collected. Chlorophyll contents, bud number and width of Phragmites communis Trin. populations after their seeds were sown in seedbeds, and the growth of seedlings according to salt contents were also determined. The results lare summarized as follows: The height and basal diameter of shoot, leaf length and width, and total dry weight of Phragmites communis Trin. were very different from each other according to their natural habitats. The bud number of seeds was increased as sample sites moved from estuary to fresh water areas and salt marsh. The but the bud diameter turned out to be in reverse proportion to the bud number. The chlorophyll content of the population from fresh water was
