“…This observation emphasises the significance of anthocyanins in the tolerance of plants to SS. These findings are consistent with earlier research showing that exogenous MT application increased anthocyanin levels [ 53 , 54 ]. Application of MT further boosted the level of anthocyanin in sword lily, and maximum accumulation was noted in response to MT3 ( Fig.…”

“…Phenolic substances are secondary metabolites with significant antioxidant activity, which can protect plants from oxidation. Sandoval et al [61] reported that melatonin treatment of high-bush blueberries increased total phenol content by 27%. In this study, polysaccharides, total flavonoids, and total phenols were significantly increased in Dendrobium PLBs under MT treatment on the 30th day.…”

Dendrobium officinale Kimura & Migo is a perennial herbaceous plant of the genus Dendrobium in the family of Orchidaceae with high medicinal value. Melatonin (MT) is an indole-like tryptamine with functions such as regulating plant growth and development. This experiment investigated the effects of different concentrations of MT on the growth and development of protocorms of D. officinale protocorm-like bodies (PLBs). The results showed that the changes in morphological indicators such as color, cluster size, and surface changes were more significant under 75 µM MT than those of 0 µM (CK), and the appearance of white on the PLB surface was expedited, which was more conducive to the proliferation of PLBs. MT treatment of 100 µM inhibited the differentiation of adventitious buds, and the contents of photosynthetic pigments, polysaccharides, and flavonoids were significantly increased. Moreover, as compared with CK, the activities of superoxide dismutase (SOD), peroxidase (POD), and catalase (CAT) in PLBs increased significantly, while the content of malondialdehyde (MDA) decreased gradually with 75 µM or less. In conclusion, a concentration of 75 µM melatonin can enhance the rapid propagation rate of D. officinale in vitro, providing insights into the effects of melatonin on the growth of tissue-cultured D. officinale seedlings.
