Population is an assemblage of individuals of some species living together in one habitat. One population may contain individuals of one genetic set up or of different, in which they can exchange their genetic information. Population shows various characteristics like density, natality (birth rate), mortality (death rate), age distribution, biotic potential, dispersion and growth form. It also possesses genetic characteristics like adaptiveness, reproductive fitness and persistence.

For the study of population, certain characteristics of individual species is also necessary. Therefore the parameters like dormancy, viability, seed germination etc., are studied.

(A) Plant Responses

• To study seed dormancy.

• To study seed germination.

• To study viability of seeds.

• To study average seed weight.

• To estimate average seed output.

• To study root / shoot length and weight ratio.

(B) Adaptation and Genetic Response

• To study adaptation in plants in relation to water.

• To  study  adaptation  in  plants in relation to different soil conditions.

• To study plant interaction and adaptation.
