   Instrument introduction:
The plant transpiration rate tester is also known as the plant transpiration conductivity tester. Plant transpiration rate refers to the rate at which water passes through the plant body (mainly leaves) to the atmosphere as a gas when it passes through the plant body. Plant transpiration can generate transpiration pull, which is the main driving force for plants to passively absorb and transport water, which is especially important for tall trees; transpiration can transport materials in xylem juice, and synthesize mineral salts and roots in the soil. Matter can be transported and distributed to various parts of the plant body with the absorption and collection of water; transpiration can also reduce the temperature of the plant body and prevent the leaves from being burned. The normal progress of transpiration is conducive to the assimilation of CO2, because the stomata are open when the leaves perform transpiration, and the open stomata become the channels for CO2 to enter the leaves. Therefore, the measurement of plant transpiration rate is of great significance for agricultural scientific research, teaching, horticultural research, forestry research, etc.
