烟和烟水浸出物对种子萌发的促进作用近年来受到广泛关注。然而，烟雾和植物激素对种子萌发的联合影响仍不清楚。研究了生菜种子对烟熏溶液的反应，以及烟熏溶液如何缓解脱落酸(ABA)胁迫。结果表明，植物提取物烟熏处理的种子萌发速度、发芽率、鲜重、相对发芽率、峰值、发芽值、地上部和根长、发芽指数和活力指数均显著高于对照。ABA(0.1 mM)处理的种子没有萌发，但当ABA和烟雾溶液混合时，有大量的种子萌发。结果表明，烟液抑制了ABA的抑制作用，提高了萌发和幼苗活力，说明烟雾不仅在萌发水平上缓解了ABA胁迫，而且在苗期也减轻了ABA胁迫。
The stimulation of seed germination by smoke and aqueous smoke extracts has received much attention in recent years. However, the combine effects of smoke with plant hormones on seed germination remain unknown. This investigation describes how lettuce (Lactuca sativa) seeds respond to smoke solution and how the smoke solution can alleviate abscisic acid (ABA) stress. The results showed that plant extracted smoke treated seeds had significantly quicker germination, higher germination percentage, fresh weight, relative seed germination percentage, peak value, germination value, shoot and root length, germination index and vigor index as compared to control. No germination was observed in ABA (0.1mM) treated seeds but significant number of seeds germinated when ABA and smoke solutions were mixed together. It was observed that smoke solutions overcome the inhibitory effects of ABA and improved germination and seedling vigor, indicating that smoke alleviated ABA stress not only at the germination level but also at seedling stage.
