An efficient in vitro propagation protocol for Pinguicula lusitanica, a rare insectivorous plant

In this study, an efficient protocol was developed for in vitro propagation of Pinguicula lusitanica L., a rare insectivorous plant with pharmacological value and limited reproductive capacity. The effects of two concentrations (0.1 and 0.5 mg l−1) of a range of plant growth regulators, including cytokinins (BA, KIN, and ZEA) and auxins (IAA, IBA, and NAA), and three concentrations of MS medium macronutrients (total, 1/2 and 1/4MS) on...
