摘　　要：次生代谢过程是植物在面临环境胁迫、病原微生物侵染以及草食性动物采食等过程时激活的一种防御反应,通常伴随着次生代谢产物的合成与大量积累,以增强自身的免疫力和抵抗力。次生代谢产物可划分为苯丙素类、黄酮类、单宁类、醌类、类萜、甾体及其甙、生物碱七大类,主要作为原料被广泛用于医药、化工、食品等其他领域,然而天然次生代谢产物产量较低,因此利用诱导子提高植物次生代谢产物产量开启了一项新的研究领域,可以显著提高经济效益,降低生产成本。通过系统介绍诱导子的分类及其诱导植物次生代谢产物合成的作用机制,并对生物诱导子(多糖、酵母提取物、细菌诱导子、真菌诱导子)与非生物诱导子(光照、高低温、干旱、重金属、激素等)的研究与应用进行阐述,以期为次生代谢产物的利用与发展提供理论依据。Secondary metabolism is a defensive response activated by plants in face of environmental stress, pathogenic microbial infection and herbivorous animal feeding. It is usually accompanied by the synthesis and accumulation of secondary metabolites to enhance their immunity and resistance. Secondary metabolites can be divided into seven categories: phenylpropanoids, flavonoids, tannins, quinones, terpenoids,steroids and their glycosides, alkaloids, mainly used as raw materials in medicine, chemicals, food and other fields. However, the yield of natural secondary metabolites is low, so the use of inducers to increase the production of plant secondary metabolites has opened a new research field, which can significantly improve economic benefits and reduce production costs. In this paper, the classification of inducers and the mechanism in inducing the synthesis of plant secondary metabolites are systematically introduced, and the research and application of biotic inducers(polysaccharides, yeast extracts, bacterial inducers, fungal inducers) and abiotic inducers(light, high and low temperature, drought, heavy metals, hormones, etc.) are also described, hoping to provide a theoretical basis for the utilization and development of secondary metabolites.
