摘 要: | 研究4种不同荫蔽度下香草兰的光合特性。结果表明:蒸腾速率和叶片水压亏缺随着荫蔽度的增加呈递减趋势;70%荫蔽度下光合速率和光合有效辐射日变化最高;胞间CO2浓度随着荫蔽度的增加呈递增趋势。说明70%荫蔽度较适宜种植香草兰。

Abstract: | Field experiments were carried out to investigate the effects of different shade degrees on vanilla photosynthesis characteristics. The results showed that transpiration rate and leaf water deficit had a declining trend with the increasing of shade degrees; the highest diurnal change of photosynthetic rate and photosynthetic active radiation appeared in 70% of shade degree; intercellular CO2 concentration increased with the increase of shade degree. In conclusion, 70% of shade degree was suitable for plant vanilla. |
