Question

Physiological factors affecting plant transpiration

Answer 1

The environmental factors affecting transpiration in plants include light, relative humidity, temperature, availability of water, and wind. Specifically, these are climatic elements which also affect photosynthesis and other plant growth and development processes

✌️✌️hey mate here is the answer....

⬇️⬇️⬇️⬇️⬇️⬇️⬇️
factors affecting transpiration:

➡️Light:
•blue light induces maximum opening of stomata.
•In the absence of light stomata remain closed. •Light also affects the rate of transpiration by increasing temperature.
•Blue and red light are effective for transpiration, constituting its action spectrum.

➡️Relative humidity:
•In humid atmosphere, the rate of transpiration decreases.
•In dry atmosphere, the relative humidity is low, so the rate of transpiration increases.

➡️Temperature:
•Higher the temperature more is the rate of transpiration as it results in a higher vapour pressure gradient.
•Lowering of temperature decreases the rate of transpiration.

➡️Wind:
•If wind is not blowing, water vapours accumulate above the transpiring leaves which decrease the rate of transpiration.
•the blowing wind removes the accumulated humidity and brings fresh air capable of absorbing water and thus, the rate of transpiration in is enhanced.

➡️Available soil water:
•If the available water in the soil is not sufficient, the rate of transpiration is decreased.
•A high concentration of salts in the soil water also reduces the rate of transpiration due to less water absorption.
