Question

Up to which point plants can extract water?

(a) Saturation Point

(b) Permanent Wilting Point

(c) Hydration Point

(d) Dissolution Point

I have been asked this question in an online quiz.

The question is from Water Requirements of Crops in chapter Water Requirements of Crops of Irrigation Engineering

Answer 1

The correct option is (b) Permanent Wilting Point

For explanation: At permanent wilting point plants can no longer extract sufficient water for its growth and wilts up. Plants are able to extract water from the soil till this point is reached. This is the point at which permanent wilting of plants take place.
