暗呼吸速率 在 生物学 分类中 的翻译结果(4)

Leaf characteristics, leaf nitrogen content, chlorophyll content, photo-synthetic rate and leaf conductance in plants grown at various sites have been studied. The thicknesses of leaf and palisade tissue of Psychotria rubra grown in the medi-closed site were greater than that of Rhodomyrtus tomentose in opened site. Nitrogen content ( mg N/g DW ) of Ardisia quinquegona in closed site was greater than that of Schima superba in opened site. Light compensation in leaves of Rhod-omyrtus tomentose and Schima superba...

Leaf characteristics, leaf nitrogen content, chlorophyll content, photo-synthetic rate and leaf conductance in plants grown at various sites have been studied。 The thicknesses of leaf and palisade tissue of Psychotria rubra grown in the medi-closed site were greater than that of Rhodomyrtus tomentose in opened site。 Nitrogen content ( mg N/g DW ) of Ardisia quinquegona in closed site was greater than that of Schima superba in opened site。 Light compensation in leaves of Rhod-omyrtus tomentose and Schima superba in higher light environment were 12 and 20 μmol。

m-2。s-1, respectively。 And the mean maximum photosynthetic rates were 11。9±0。4 and 7。5±1。8μmol。m-2。s-1 for these plants, respectively。暗呼吸速率 But light compensation for leaves of Ardisia quinquegona in closed site was 5 μmol。m-2。s-1 and photosynthetic rate was 3。18±1。90μmol。-2。s-1 for Ardisia quinquogona, light-saturated photosynthesis occurred at 200μmol。m-2。s-1, which was lower than that was happened in Rhodomyrtus tomentose in medi-closed site。The species in opened site had higher steady-value of Ci/Ca and water use efficiency whereas lower Ci/Ca and water use efficiency were found in species in closed site。 The results showed that the intrinsic defferent effects of light on photosynthesis might be involved in the light environment of their habitats。
