| 中文摘要: |
| 影响植物水分运转的主要因子有气象因子(包括太阳辐射、大气温度、大气湿度、风速、CO2浓度等)、土壤的水分状况、气孔导度、植物叶面积、水分在植物体内的传输阻力等。大量研究表明:植物蒸腾的日变化主要是由气象因子的日变化引起的,而蒸腾的年变化主要与土壤的水分状况、叶面积动态和气候条件有关。此外,组织贮存水和导管的空穴对植物的水分运转也有一定的影响。 |
| 英文摘要: |
| The main influence factors of water transport in plants are weather conditions (including solar radiation, air temperature, humidity, wind speed, and ambient CO2 concentration), soil water condition, stomatal conductance, leaf area, resistance of water transport in plants, and so on. It is showed that the diurnal variation of transpiration is caused by diurnal variation of weather conditions, while the annual variation of transpiration is mainly related to the change of soil water, leaf area and climate. Tissue storage water and xylem cavitation can also affect water transport in plants. |
