摘  要:
[目的]研究不同浓度聚乙二醇(PEG)对不同品种烟草种子发芽整齐度的影响,获得最大的发芽整齐度。[方法]利用不同浓度的PEG溶液对几个烟草品种种子进行处理,以调查该物质对烟草种子萌发性的影响。[结果]结果表明,PEG对烟草种子萌发率无明显效应,对萌发集中性有促进作用;不同品种对不同PEG溶液浓度和不同浸种时间的反应不一致,这可能与品种的遗传特性有关。[结论]该研究结果对于培育整齐一致的烟苗具有一定的参考价值。

摘  要:
[Objective]The aim was to explore effects of PEG on germinating uniformity of tobacco seeds,for getting the most germinating.[Method] Seeds of several tobacco breeds were treated by PEG at different concentrations to investigate the effects on germinating.[Result] The results showed that the PEG had no significant effects on the seed germination rate,but it promoted the concentration of seeds germination.The inconformity of each breed responding the PEG with different concentration might be explained with different genetic characteristics.[Conclusion]The results had a certain reference value for cultivating the seeds came out evenly.
