| 英文摘要 | The effects of different uv-spectra on the growth inhibition, cell oxidation and photosynthetic pigment change of cucumber and soybean seedlings were investigated under controlled environmental conditions. spectra-dependent differences in growth and oxidation indices existed within uv-a bands as well as uv-b bands. the plant growth biologically spectra weighting function (bswf) matched well with average plant response in uv-b region, but not in uv-a region. shorter uv-a wavelength imposed more negative impact than longer uv-a wavelength did in both species. the previous literatures and our results add weight to suggestion that dicotyledonous species would be more sensitive to shorter uv-a wavelength than monocotyledonous species. while we await continued and further studies on plant responses to different uv-spectra treatments under different experimental conditions with diverse taxa. the effect on photosynthetic pigment was related to different uv bands and different species. under disproportionate uv/par light conditions, photosynthetic pigment content was decreased by uv-a spectra as well as by uv-b spectra, but the ratio of total carotenoids to total chlorophyll was increased in cucumber seedlings. the possible implications of these observations were also discussed.
