Important Definations I
Condition of soil moisture deficiency or water scarcity.
2. Drought Avoidance:
Ability of plants to maintain a favourable internal water balance under moisture stress.
3. Drought Hardening:
Improvement in drought tolerance ability of a genotype through various seed and seedling treatments.
4. Drought Resistance:
Ability of crop plants to grow, develop and reproduce normally under moisture deficit condition or survival of plants under water deficit conditions without injury. It is a sum of drought avoidance and drought tolerance.
5. Drought Tolerance:
Ability of plants to withstand low tissue water content.
Growing of plants in nutrient solution.
Cemented micro plots of various sizes used for study of roots and salt tolerance.
An instrument that is used for measuring stomatal aperture.
An instrument which is used to measure tissue water potential in plants.
10. Salts Tolerance:
Ability of plants to prevent, reduce or overcome the injurious effect of soluble salts present in the root zone.
