ABSTRACT

For any plant seed, the primary life elements (e.g. amino acids, lipids, sugars, nucleic acids and those related to control the production of pri­ mary metabolites) are required for a normal germination process. Re­ markable and at difference from animals, the emerged plantlet cannot move away from the germination place, it should survive and reproduce itself just taking the necessary nutrients from the surrounding environ­ ment, despite the environmental and biological changes.
