Environment factors that affect salt absorbtion in plant

A) Temperature :

  • increase temperature will increase rate of salf absorption. Over optinum temperature will have inhibitory effect by denature of enzyme

B) pH :

  • pH affect the ionization of the electrolytes

C) Light :

  • light affect opening of stomata, which than affect the rate of transpiration.
  • light effect the rate of photosynthesis, thus affect the rate of active transport.

D) Oxygen tension :

  • oxyten tension affect the rate of respiration, thus affect the availability of ATP for active transport.
