This study investigated potential phytotoxic effects on germination and root growth of 21 plant secondary metabolites (sinapinic, syringic, vanillic, ferulic, p-coumaric, chlorogenic, gallic, gentisic, protocatechuic, p-hydroxybenzoic, and trans-cinnamic acids, and eucalyptol, quercetin, vanillin,
Seed priming is a treatment that controls seed water content to partially activate germination processes such as metabolism but prevents full germination of the seeds. The treatment is well known to enhance seed performance, including germination, but sometimes reduces seed storability or longevity
