“…Oliveira et al (2011), for example, found that supplementation gives better results in the number of shoots, but in vitro rooting is superior in culture medium without the addition of plant regulator. Specifically on cassava, better results without BAP supplementation were also verified by Silva, Ferreira and Gato (2015), for rooting parameters and multiplication rate, thus becoming the most suitable for seedling production.…”

The implantation of a model of sustainable development for agriculture can happen with the contribution of the mandiocultura. But for this, culture needs to be strengthened. In vitro propagation is an instrument for this purpose. Micropropagation can provide growers with large quantities of vigorous and healthy cassava seedlings in a short time. The objective of this study was to evaluate the in vitro establishment of four varieties of cassava cultivated in the municipality of Colorado do Oeste, State of Rondônia, popularly known as Arara, Caturra, Cacau Vermelha and Roxinha. For that, an experiment was carried out in the Laboratory of In Vitro Cultivation at the Pole of Technological Innovation of the University of Cruz Alta (UNICRUZ), with a completely randomized design in a 4 x 2 factorial scheme, with 6 replications. The treatments consisted of explants grown in Murashige and Skoog (MS) medium without the presence of growth regulator and MS medium supplemented with of 6-benzylaminopurine (BAP). The results indicate that the average contamination percentage of the explants was 47.19%, differing among the varieties. The best growth response in culture media, in the multiple comparison of means (Scott-Knott's test, 5%), was obtained with MS medium without BAP addition, with significant difference between varieties. Under the conditions of this experiment, it was evidenced that micropropagation is a viable tool for obtaining varieties of interest, with desired phytosanitary qualities, with varietal and large scale authenticity.

“…These analyses were performed using Graph Pad in Stat version 3.01. For the analysis of rooting percentages according to the means, a percentage difference test (p1 and p2) at the 5% significance level was carried out using Statistica for Windows TM version 5.0 (14) .…”

Psychotria ipecacuanha, é uma planta medicinal nativa da América com a maior área de ocorrência no Estado de Mato Grosso - Brasil, críticamente ameaçada devido à sobreexploração das populações naturais. Devido à dificuldades na propagação convencional, o objetivo deste estudo foi a avaliação do efeito de diferentes concentrações do regulador de crescimento ácido indolacético (AIA) na propagação in vitro de P. ipecacuanha. Segmentos nodais foram cultivados em meio de Murashige e Skoog (MS) sem reguladores de crescimento (controle) e suplementado com quatro concentrações (0,05; 0,5; 1,5 e 2,0 mg.L-1) de AIA, em meios semi-sólidos. Após 60 dias de cultivo, segmentos nodais (n=30) cultivados em meio de Murashige & Skoog (MS) suplementado com 0,05 mg.L-1 de AIA produziram, em média, 4,56 segmentos nodais por explante, cujas plântulas foram aclimatizadas com sucesso, sem exibição de qualquer anomalia morfológica ou variação.
