Abstract:

Changes of germination, physiological and biochemical characteristics of tobacco seeds at different storage time were studied to provide references for tobacco germplasm conservation and field production. The seeds of tobacco variety ‘Honghuadajinyuan’ stored at room temperature for 0-12 months were used as materials to study the changes of germination characteristics, antioxidant enzyme activities, osmotic regulation substances (proline, soluble sugar), malondialdehyde (MDA) and relative conductivity during storage. The results showed that the vigor indexes, germination potential, germination rates and germination indexes of seeds increased first and then decreased with the extension of storage time. The highest germination rate was 93.21% after storage for six months, and the seeds basically lost germination activity after storage for 12 months. With the extension of storage time, superoxide dismutase, peroxidase and catalase activities, proline and soluble sugar contents decreased, MDA content and relative conductivity increased. This indicated that during the aging process of tobacco seeds, the germination ability of seeds increased first and then decreased, the activities of antioxidant enzymes decreased as a whole, the consumption of osmotic regulation substances decreased, and the damage of cell membrane intensified. In the actual production, seeds stored at room temperature for six months are recommended.

Key words: Tobacco, Seed germination, Storage time, Physiological and biochemical characteristics
