摘    要:对烟草种子进行引发,在萌发过程中回干处理,分析这些措施对种子萌发率和种子内物质含量的影响.结果表明,引发72h回干处理的烟草种子萌发率最高,催芽后48h达到93%,比对照(正常种子)提前了72h.经过引发回干处理的种子再进行催芽时,种子内的蛋白质、可溶性蛋白、淀粉等大分子物质被均衡利用,其含量变化较平稳;游离氨基酸、可溶性糖等一些有利于萌发、提高种子活力的物质含量较高.

关 键 词:烟草  种子萌发  引发回干处理  种子丸化包衣技术  萌发率  游离氨基酸  蛋白质  可溶性糖

Abstract:The effect of priming and drying treatment on tobacco seed germination rate and several component content in seedling bourgeon and growth process were analyzed. The result showed that the highest germination ratio of seed was of the seed by priming 72 hours and drying treatment. Its germination ratio reached 93% when the seed bourgeoned to 48 hours and was 72 hours earlier than that of the contrast. By priming and drying treatment, the content change of protein, soluble protein and starch, which was used balancedly in the process of seed bourgeon, was stabler and the content of free amino acid and soluble sugar in seed which can benefit seed bourgeon and improve seed vitality was higher than that in the contrast seed.
Keywords:tobacco seed  seed priming and drying treatment  seed bourgeon
