“…We can link the biostimulant response to root growth to a large number of nutrients present not only due to the presence of pectin. Furthermore, the length of the roots can be related to the content of flavonoids in pectin that improves the availability of nitric oxide, which directly affects the stem cells responsible for plant root growth [51][52][53][54]. The development of the new culture medium (T3) from Opuntia and its operating efficiency suggested producing a functional substrate for the optimal growth of orchid species, without modifying the chemical composition or the nutriment requirements for toe orchid growth.…”

Development of Agar Substitute Formulated with Mucilage and Pectin from Opuntia Local Waste Matter for Cattleya sp. Orchids In Vitro Culture Media

The technology for reproducing orchids in vitro has had to evolve due to the demand for these plants and the high cost of the biotechnology used due to the agar, the gelling agent. Consequently, research has tended to search for natural substitutes for agar. Our work describes the use of pectin and mucilage hydrocolloids extracted from the local waste matter of two species of Opuntia (O. ficus-indica and O. robusta) to study as a gelling agent in vitro culture media for Cattleya sp. These hydrocolloids were obtained by alkaline hydrolysis. Subsequently, these were used in proportions of 0.8%, 0.6%, 0.4%, and 0.2% in combination with agar to study the gelation time, texture profile analysis (TPA), seed germination under light and dark conditions, and a phenological study, including orchid analyses of leaves and roots, root and leaf length, seedling height, and width of the best-designed treatment were studied. Our results demonstrate that the treatment composed of 0.4% O. ficus-indica pectin and 0.4% agar improves the germination time, plant growth, and the number of leaves and roots, resulting in a biostimulant formula for optimal in vitro growth of Cattleya sp.
