  • Effects of Oxidants on the Carotenes in Plant Leaves

抄録

The effects of of oxidants on carotenes in plant leaves were investigated under laboratory condition or in field survey.<BR>The plants used for controlled-chamber study were carrot (Daucus carota L.) and Ginkgo tree (Ginkgo biloba L.), both of which contain a-carotene and β-carotene. The Ginkgo and carrot were exposed to O3 at 0.3 ppm, 6h/day for 3 days, and at 0.25 ppm, 6h/day for 2 days, respectively. In both cases, a-carotene in the leaves decreased significantly, whereas jS-carotene decreased slightly. Therefore, the reduction of the α-carotene/β-carotene ratio can be used as an indicator of O3 in jury to the leaves.<BR>The carotene contents and α-/β-carotene ratio in Ginkgo leaves were investigated for two years (1975-1976) in the air-polluted area (Osaka-shi and Sakai-shi). As control area Yamato highland in Nara prefecture was chosen. The Ginkgo leaves in the air-polluted area showed much more degradation of α-carotene than that of n-carotene. It was suggested that the reduction of the α-/β-carotene ratio was caused by oxidants in the air.
