We know that the hormones are widely used in the agricultural production. Auxins are arguably the most important signaling molecules in plants and have a profound impact on plant growth and development (Weijers & Wagner 2016). Gibberellic acid (GA3) is an important plant growth hormone which can accelerate stalk and leaf growth, improve seed shooting and increase fructification yield (Tang et al. 2000). The role of ethylene in defense responses to pathogens is widely recognized (Dubois et al. 2018). The 6-benzyl aminopurine (6BA) is one kind of cytokinin which can inhibiting the decomposition of chlorophyll, nucleic acid and protein in plant leaves, keeping green and preventing aging (Wojtania & Skrzypek 2014). Brassinosteroids (BRs) are steroidal plant hormones that are widely distributed in lower to higher plants, and the brassinolide (BL) exhibits the highest biological activity among naturally occurring BRs (Kim et al. 2000). Salicylic acid (SA) is a phenolic compound which can regulate plant physiological functions, such as seed germination, photosynthesis, respiration, growth and flowering (Rivas & Plasencia 2011). Plant growth regulator methyl jasmonate (MeJA) is a member of jasmonate group, which can regulates many aspects of plant growth and development. MeJA is known as a signaling molecule which plays a role in many biotic and abiotic stress responses.

Brassinolide improves plant resistance against Cd stress, promoting their growth by increasing the plant height, biomass, and yield [26, 27]. For example, under Cu stress, 24-epibrassinolide alleviates the stress impacts on Brassica juncea resulting in increased plant biomass [11]. In this study, BR increased the aboveground biomass of N. officinale in Cd-contaminated soil, indicating that BR could promote the growth of N. officinale under stress. This was consistent with the promotion of growth in tomato seedlings under Cd stress [14]. However, BR had no significant effects on the root biomass of N. officinale under Cd-contaminated soil. This could be because BR was applied on the leaves, directly impacting the stems and leaves (shoots) but less affecting the roots. The effects of BR on N. officinale are consistent with its effects on other plants [26, 27].
