Plant transpiration rate meter RC-TRM01

1．Characteristics and functions of the instrument

Plant transpiration rate refers to the rate at which water passes through the plant body and radiates into the atmosphere in the form of gas through the plant body surface (mainly leaves).

Transpiration force produced by plant transpiration. Transpiration force is the main driving force for plants to passively absorb and transport water.

This is especially important for tall trees; transpiration can promote the transportation of substances in xylem sap, mineral salts and roots in soil Synthetic substances can be transported and distributed to various parts of the plant body along with the absorption and collection of water;

transpiration can also reduce the temperature of the plant body and prevent the leaves from being burned.

This is because the water has a high heat of vaporization. A large amount of radiant heat can be lost during transpiration.

The normal progress of transpiration is conducive to the assimilation of CO2. This is because when leaves are transpired, the stomata are open, and the open stomata become channels for CO2 to enter the leaves.

Therefore, the stomata conductance is also important for plant transpiration rate and photosynthesis rate. Meaning.

The measurement of plant transpiration rate and stomatal conductance is of great significance to agricultural scientific research, teaching, horticultural research, and forestry research.
