Efecto del acido indolacetico y 6-Benzylaminopurina en el crecimiento y desarrollo In vivo de sphagnum

Abstract

The bryophytes represent the oldest existing lineage of terrestrial plants and are distinguished by no vascular tissues themselves. This type of plants exhibits very small sizes, they inhabit almost all ecosystems and have a great diversity of species. However, this division of plants has an importance at the ecological level, which unfortunately have been diminished by loss of biodiversity. They are also considered relevant in biotechnology studies, which has allowed the determination of endogenous phytohormonal profiles in these organisms, providing remarkable information about the evolution of hormones in plants, which encourage the regulation of growth and development processes vegetable. Consequently, the present investigation seeks to evaluate the effect of the plant hormones "Indoleacetic acid" (AIA) and "6-Benzylaminopurine" (BAP), on the longitudinal growth and development of in vivo chapters of Sphagnum mosses. The protocol was standardized in terrarium condition, handling different concentrations below 1ppm, on a factorial arrangement of 4x4, established in 16 treatments, for the process of regeneration of 1 cm explants taken from the moss chapter analyzed; this methodology showed that in high concentrations of AIA (0.5ppm) and in the absence of BAP, the longitudinal growth is evident with respect to the other interactions proposed; In the same way, in the development of chapters, the interaction of BAP concentrations 1ppm and AIA 0.05ppm, shows a possible beneficial cooperation in the continuous formation of chapters, throughout the examined fascicles.
