【 摘 要 】

The light saturations of photochemical reactions of rice chlorina mutant, CMV-44, which lacks chlorophyll b entirely, were examined as well as those of the barley chlorina f2 mutant. The efficiencies of the photoreactions of photosystem I and photosystem II were lower in a rice chlorina mutant than in a wild-type plant. Based on the findings in the present investigation, the plant leaves with higher chlorophyll b content, having a larger photosynthetic unit, are considered to exhibit relatively high photosynthetic activity in low light conditions as in the plant canopy, under the cover of protected cultivation and in the winter season.
