Abstract

On Hyponex media with varying concentrations of crude polysaccharides from mix-cut Dendrobium hybrids, namely D. Sonia ‘Red Jo’, D. ‘Suree Classic’, and D. ‘Black Pearl’ from Mana Orchid Farm, Thailand, seedlings of D. cretaceum were in vitro cultivated at a height of around 0.5 cm.
The culture medium was supplemented with polysaccharides at concentrations of 0, 25, 50, 100, 200, and 400 mg L^‑1 for three months.
The results showed that D. cretaceum seedlings grown on Hyponex media supplemented with 100.0 mg L^‑1 polysaccharides produced the most roots (0.222 g), fresh weight (0.222 g), and shoot length (1.53 cm) (6.5 roots). However, the quantity of shoots among the treatments is not noticeably different.
Our findings showed that all treatments with polysaccharides added to the cultured medium exhibited greater growth and development than the control without polysaccharides added in terms of fresh weight, number of roots, shoot, and root length.
Additionally, compared to the control without polysaccharides added, all treatments with polysaccharides added to the cultured medium showed higher TEAC and shorter IC₅₀.
