Secondary constituents 二次代謝產物 are influenced by (i) heredity (ii) ontogeny (iii) environment. Genetic effects induce both qualitative (量) and quantitative (品質) changes while ontogeny and environment affects qualitative primarily.Heredity (genetic composition): e.g. Some Claviceps strains give the "desired" Ergotamine while others give small concentrations of complex mixtures of alkaloidsOntogeny (stage of development): e.g. in Cannabis, cannabidiol peaks early then decline, whereas tetrahydrocannabinol increases until maturity. in poppy, morphine is highest 2-3weeks after flowering, b...

Ontogeny→影響Papaver somniferum(Morphine)、Cannabis sativa (大麻；迷幻成分△THC)二次代謝產物的因素Heredity→影響大部分植物，例：Claviceps purpurea (Ergot)、Eucalyptus globus (桉葉，Myrtaceae桃金孃科)、Strophanthus kombe(毒毛旋花子)二次代謝產物的因素
