We investigated seasonal variation in photosynthetic characteristics and chlorophyll content of the Loranthus tanakae, Viscum album var. coloratum and its hosts in Korea. The maximum photosynthesis and transpiration rate of L. tanakae were 9.36 micromol.m-2.s−one at 941 micromol.m−2.s−1 PAR (photosynthetically active radiation) in June, 5.06 micromol.m−2.s−one at 1,596 micromol.m−2.s −one PAR in July, respectively. The maximum photosynthesis and transpiration rate of V. album var. coloratum were 6.51 micromol.m−2.s−one at 418 micromol.m−2.s−one PAR in Autumn, 3.91 micromol.m−2.s−one at 1,735 micromol.m−2.s−one PAR in Autumn, respectively. V. album var. coloratum was able to conduct photosynthesis in November whereas its host and L. tanakae were not able to conduct photosynthesis. Especially transpiration rate of L. tanakae were always higher than its host and V. album var. coloratum. The chlorophyll a+b contents of L. tanakae was 8.23 mg.g−one in July, V. album var. coloratum was 10.27 mg.g−one in June, and chlorophyll a/b ratio of L. tanakae was 1.7~3.7, V. album var. coloratum was 1.1~4.5, depend on season.
