    前体物质和诱导子对红松松多酚合成的影响

    Effects of precursors and elicitations on the synthesis polyphenols of Pinus koraiensis.

    • 摘要: 研究不同浓度的前体物质(苯丙氨酸和肉桂酸)和诱导子(茉莉酸甲酯和水杨酸)对红松树皮中松多酚合成 的影响,初步探讨前体物质和诱导子影响红松松多酚合成的机制。结果表明:苯丙氨酸和肉桂酸作为松多酚合成 的前体物质,可以显著提高红松树皮中松多酚的含量,最佳添加浓度分别为400 和100 μmol/ L,与对照组相比含量 增加了(11.74 ±1.09)mg/ g 和(8.90 ±0.912)mg/ g,两者不具有协同作用;茉莉酸甲酯和水杨酸可以有效诱导松多 酚的合成,最佳诱导浓度为60 和80 μmol/ L,松多酚的含量分别增加了(7.23 ±1.05)mg/ g 和(14.68 ±1.04)mg/ g, 两者之间存在拮抗作用。前体饲喂和激素诱导这2 条途径均可以促进红松树皮中松多酚的合成。

       

      Abstract: This study was to explore the effects of precursors ( phenylalanine and cinnamate acid) and phytohormones (methyl jasmonate and salicylic acid) on the synthesis of pine polyphenols in the rind of Pinus karaiensis twigs. Possible mechanisms of their effects were also discussed. Our results showed that, phenylalanine and cinnamic acid as a precursor of the polyphenols synthesis, could increase the amount of pine polyphenols. The content of polyphenols increased by (11.74 ±1.09)mg/ g and (8.90 ±0.912) mg/ g,respectively when the best addition concentration of phenylalanine and cinnamic acid reached 400 and 100 μmol/ L. And phenylalanine and cinnamic acid had no synergy. On the other hand, phytohormone could effectively induce polyphenol synthesis. The content of pine polyphenols increased by (7.23 ±1.05) mg/ g and (14.68 ±1.04) mg/ g, respectively when the best addition concentration of methyl jasmonate acid and salicylic acid reached 60 and 80 μmol/ L. Methyl jasmonate acid and salicylic acid were antagonisitic to each other. So pine polyphenols in the bark of P. koraiensis can be promoted by the way of precursor feeding and hormonal induction.
