Question

Soil salinity affects the plant growth by

• A. Reducing the roots ability to extract water from the soil
• B. Reducing the rate of flowering
• C. Reducing the rate of ripening
• D. None of the above

Answer 1

The correct option is A Reducing the roots ability to extract water from the soil

Soil salinity may be due to the presence of soluble salts in the soil water. This causes salt stress. Due to the presence of salts, the rate of absorption of water is decreased. The absorption of the water with salts may cause cell injury because the water is evaporated as transpiration. There is an accumulation of the salts which may result in cell injury. Hence, the plant will prevent the uptake of salt water and there will be a reduction in the water absorption.

Thus, the correct answer is option A.
