摘要

Alternative supports can be successfully used in place of agar for in vitro culture to increase seedling vigor. The objective of thepresent study was to evaluate the efficiency of alternative support materials compared to agar in the in vitro cultivation of Mouririelliptica (Mart.) in the absence or presence of naphthalene acetic acid (NAA). The alternative support materials used were medium-grain vermiculite, sugarcane (Saccharum spp. L.) bagasse and queen palm fiber [Syagrus romanzoffiana (Chamisso) Glassman]. Forthis, young plants with at least two axillary buds under in vivo conditions were transferred to in vitro condition considering fourreplications with three young plants. After 45 days was evaluated the growth and anatomical explant characteristics. Autoclavingthese alternative supports without the media and proceeding the explant desinfestation was an efficient method to contaminationcontrol and plant growth in a in vitro condition. No differences were observed between agar, vermiculite and sugarcane bagassecultures for most growth characteristics evaluated. Greater numbers of adventitious and secondary roots and greater root lengthwere significantly observed in plantlets grown in the presence of vermiculite and the absence of naphthalene acetic acid. In theagar culture, roots had weak points and poorly differentiated tissues, with parenchymal tissue predominating. The addition of 2.0mg L -1 naphthalene acetic acid used did not stimulate rooting in this specie. So, other auxin source and concentrations should beevaluated in future studies. Both support materials used, vermiculite and sugarcane bagasse, representing promising agarsubstitutes to obtain seedlings with roots.
