Abstract: As a kind of important production material, seeds played an irreplaceable role on the development of agriculture-stock production and the preservation of germplasm resources. There was active meaning for the researches on seed aging and measures of keeping or improving seed vigor in the seeding and storing. This paper mainly summarized the seed aging phenomenon, elaborated the physiological and biochemical changes during seeds aging process from the seed germination and seedling growth, enzyme activity, respiration and energy systems, storage substances, nucleic acid and protein, cell structure and the membrane permeability, accumulation of toxic and harmful substances, analyzed and compared the measures to repair and improve seed vigor including priming technology, dry-wet processing, nutrients treatment and plant growth regulator treatment. At last, the research direction and development trend of seed vigor and mechanism of physiological aging was discussed.
