Iron Chelate and coconut water in in vitro germination of Rossioglossum grande (Orchidaceae)

摘要

Rossioglossum grande (Lindl.) Garay & G.C. Kenn is a Mexican native orchid threatened to extinguish according to the NOM-059-Semarnat-2010. in vitro asymbiotic germination is a conservation tool widely used for threatened orchids. Generate basic knowledge about in vitro response of R. grande was the object of the work, comparing seed germination in Knudson C medium (KC) versus Dalla Rosa y Laneri medium (DR), modified adding iron chelate and coconut water. We distinguished three different stages of culture: the sowing culture (CM) and two subcultivated culture (C1 and C2). Experimental design was totally aleatory. Anova, Tu
