The commercial importance of plant tissue culture has grown in recent years, reflecting its application to vegetative propagation, disease elimination, plant improvement and the production of polyphenols. The level of polyphenols present in plant tissue is influenced by crop genotype, the growing environment, the crop management regime and the post-harvest processing practice. Globe artichoke is a significant component of the Mediterranean Basin agricultural economy, and is rich in polyphenols (phenolic acids and flavones). Most commercially grown plants are derived via vegetative propagation, with its attendant risk of pathogen build-up. Here, a comparison was drawn between the polyphenol profiles of conventionally propagated and micropropagated/mycorrhized globe artichoke plants. Micropropagation/mycorrhization appeared to deliver a higher content of caffeoylquinic acids. The accumulation of these compounds, along with luteolin and its derivatives, was not season-dependent. Luteolin aglycone was accumulated preferentially in the conventionally propagated plants. Overall, it appeared that micropropagation/mycorrhization enhanced the accumulation of polyphenols.
近年来，植物组织培养的商业重要性日益增加，反映了其在营养繁殖、消除病害、植物改良和多酚生产方面的应用。植物组织中多酚的含量受作物基因型、生长环境、作物管理方式和采后加工实践的影响。朝鲜蓟是地中海盆地农业经济的重要组成部分，富含多酚（酚酸和黄酮类化合物）。大多数商业种植的植物是通过营养繁殖获得的，这伴随着病原体积累的风险。在这里，对常规繁殖和微繁殖/菌根化朝鲜蓟植物的多酚谱进行了比较。微繁殖/菌根化似乎提供了更高含量的咖啡酰奎宁酸。这些化合物与木犀草素及其衍生物的积累与季节无关。木犀草素糖苷元优先在常规繁殖的植物中积累。总的来说，似乎微繁殖/菌根化增强了多酚的积累。
