摘要/Abstract

摘要： 以珍稀濒危药用植物三叶青（Tetrastigma hemsleyanum Diels et Gilg）为材料，通过遮荫条件下（30%自然光）的盆栽试验，研究了硝态氮（NO₃^--N）和铵态氮（NH₄⁺-N）两种不同氮素形态对其根和叶中黄酮类活性成分含量的影响并探讨其机制。结果表明：NO₃^--N处理后的三叶青叶中原花青素B1、芦丁、山柰酚-3-O-芸香糖苷、槲皮素、异槲皮苷、山柰酚的含量比NH₄⁺-N处理的高；其根中的原花青素B1、芦丁、山柰酚-3-O-芸香糖苷、槲皮素、异槲皮苷、山柰酚的含量比NH₄⁺-N处理的高。进一步的研究发现NO₃^--N处理过的三叶青其根、叶中与黄酮类化合物合成相关的酶苯丙氨酸解氨酶（PAL）、查尔酮合成酶（CHS）转录与表达水平高于NH₄⁺-N处理的三叶青。此外，NO₃^--N处理的三叶青叶、根中的PAL和CHS酶活性也高于NH₄⁺-N处理。利用PAL特异性抑制剂AOA处理后，AOA能显著抑制PAL酶活性（P<0.05）并导致黄酮类成分含量极显著下降（P<0.01）。综上所述，施用NO₃^--N更有益于三叶青黄酮类化合物的生物合成，其主要是通过增加PAL代谢途径关键酶的基因表达量进而提高其酶活性来增强黄酮类化合物的合成。

Abstract: The effects of two different nitrogen(N) forms(nitrate-N and ammonium-N) on the accumulation of flavonoids(procyanidin B1, rutin, kaempferol-3-O-rutinoside, quercetin, isoquercitrin and kaempferol) in the endangered medicinal plant Tetrastigma hemsleyanum(from Zhejiang Province) were examined through potted experiment under shady condition(30% natural light), and its influence mechanism was also discussed. The flavonoids content was relatively higher in the root and leaf of T. hemsleyanum under nitrate-N supply than ammonium-N supply. The levels of transcription and expression of phenylalanine ammonia-lyase(PAL) and chalcone synthase(CHS) which are related to flavonoids synthesis were relatively higher in the root and leaf of T. hemsleyanum under nitrate-N supply than ammonium-N supply. Besides, the enzyme activities of PAL and CHS were also higher in the root and leaf of T. hemsleyanum under nitrate-N supply than ammonium-N supply. The PAL-specific inhibitor(AOA) could significantly inhibit the enzyme activity of PAL(P<0.05) and lead to a very significant decrease in flavonoids content(P<0.01). In conclusion, nitrate-N supply is more beneficial to flavonoids synthesis in T. hemsleyanum, which mainly enhances the flavonoids synthesis by increasing the gene expression and activity of key enzymes in PAL metabolic pathway.
