Abstract: | The process of seeds' germination has always aroused the interest of researches, if considering its special - both theoretical and practical - importance. This extremely complex process involves a multitude of biochemical and physiological processes through which the glucides, lipids and reserve proteins are mobilized for assuring the precursors necessary to the biosynthetic processes occurring in the embryo and in the future plant, up to the initiation of the photo-synthetic transformations.
It may be assessed that, to some extent, the biochemical transformations occurring during germination are the reverse of the ones developed during seeds' maturation (and, respectively, during the formation of bulbs, tubercles, etc.) (TĂNASE et al., 1997).
Following maturation, in the organs in which the reserve substances are deposited, the biochemical and physiological processes develop at a considerably lower rate, until reaching a minimum intensity, necessary to the maintenance of their vital capacity. In the moment when they are brought to optimum conditions of humidity, temperature, saline concentration, pH, etc., the reverse processes - which are mainly hydrolytic or phosphorolytic - begin to be manifested. |
