Evaluación del efecto rizogénico de productos orgánicos en dos tipos de sustrato en esquejes de hortensias (Hydrangea macrophylla)

Within the industry for the production of ornamental plant species, the hydrangea (Hydrangea macrophylla) is one of the moststriking and popular, due to its beauty and the size of its inflorescences. Its production starts regularly from terminal cuttings thatneed to be rooted. In the present work, the rhizogenic capacity of four commercial products based on growth regulators and twoorganic products was tested: aloe medullary parenchyma and algae extract. The results found showed the efficiency of aloe vera toproduce callus in the cuttings and maintain their turgidity, which implies that it can be used on a small and medium scale in therooting of herbaceous cuttings such as those of Hydrangea macrophylla.
