Write any four factors affecting water absorption in plants.

Answer 1

1. The presence of capillary water is essential.
2. The rate of water absorption is maximum at soil temperatures between 20°C and 30°C.
3. High concentrations of solutes in soil water reduce the rate of absorption of water.
4. Poorly aerated soil shows poor absorption rates.
5. Increased transpiration accelerates the rate of absorption of water in the irrigated soil.
