红松( Pinus koraiensis)是我国东北地区的优势树种,经济价值极高。松多酚是从红松组织中分离出来的一类次生代谢产物,具有很强的生理活性,有助于预防癌症和心脑血管疾病的发生(Morton et al.,2000; Tassoni et al.,2012)...红松( Pinus koraiensis)是我国东北地区的优势树种,经济价值极高。松多酚是从红松组织中分离出来的一类次生代谢产物,具有很强的生理活性,有助于预防癌症和心脑血管疾病的发生(Morton et al.,2000; Tassoni et al.,2012)。松多酚作为一种天然、无毒、高效的抗氧化剂,可以广泛应用于食品、保健品和医药领域,因此如何采取有效的措施提高松多酚的含量具有重要意义。稀土是一类具有生理活性的元素,可以对植物产生多种生理效应、提高种子萌发率、促进根系发育、提高生物量和增强抗逆性等,在农业上得到广泛应用( Arora et al.,2002; Hu et al.,2002;2004)。随着研究的不断深入,稀土元素(镧、铕、铈、镱等)的应用已经拓展到植物细胞和组织培养领域(Chen et al.,2004)。展开更多
