“…There are several reports in the literature highlighting the impact of low temperatures on the in vitro conservation of different plants: Piper aduncum and Piper hispidinervum [5], vetiver [6], sugarcane [4], grapevine [7], and Drosophyllum lusitanicum [8]. …”

“…Comparing the genotypes within each concentration of MS salts, it was observed that IPB-007 showed overall higher survival rates that were indistinguishable from IPB-137 only at the 75% MS salts treatment level. After the same period of in vitro conservation, vetiver microplants showed no differences between treatments containing 50% and 75% MS salts, and at a concentration of 100% MS salts, total mortality of the explants was observed [6]. …”

The aim of this study was to develop a protocol for the in vitro conservation of sweet potato genotypes using the slow growth technique. The first experiment was conducted in a 4 × 5 × 2 factorial scheme, testing four genotypes (IPB-007, IPB-052, IPB-072, and IPB-137), five concentrations of abscisic acid (ABA) (0.0, 1.0, 2.0, 4.0, and 8.0 mg·L−1), and two temperatures (18 and 25°C). The second experiment was conducted in a 4 × 3 × 3 factorial scheme at 18°C, testing four genotypes (IPB-007, IPB-052, IPB-072, and IPB-137), three variations of MS salts (50, 75, and 100%), and three concentrations of sucrose (10, 20, and 30 g·L−1). Every three months, we evaluated the survival (%), shoot height, and shoot viability. In vitro conservation of the sweet potato genotypes IPB-052 and IPB-007 was obtained over three and six months, respectively, using MS medium plus 2.0 mg·L−1 of ABA at either 18 or 25°C. Genotypes IPB-072 and IPB-137 can be kept for three and six months, respectively, in MS medium without ABA at 18°C. It is possible to store IPB-052 and IPB-072 for six months and IPB-007 and IPB-137 for nine months using 30 g·L−1 of sucrose and 50% MS salts.

“…A reduction in the metabolism of the conserved plants was achieved by reducing the temperature and the amount of MS salts used Likewise, accessions of vetiver [Chrysopogon zizanioides (L.) Roberty] were conserved under a regime of slow growth for a period of 270 days by reducing the concentration of MS salts to 25% of the normal concentration and the temperature to 18°C. For many species, a combination of different factors must be altered to obtain satisfactory results (Santos et al, 2012).…”

ABSTRACT. This study aimed to evaluate the influence of the growing environment on the in vitro conservation of citrus genotypes obtained from the Active Citrus Germplasm Bank of Embrapa Cassava and Fruit. The study used multivariate statistic tools in order to improve the efficiency in the analysis of the results. Approximately 1-cm of length microcuttings from plantlets derived from ten genotypes previously cultured in vitro were inoculated in test tubes containing 20 mL of WPM culture medium supplemented with 25 g L

RESUMOObjetivou-se com esse estudo investigar sobre a viabilidade de sementes, o resgate e a propagação vegetativa de Lagenocarpus rigidus Nees. Os experimentos foram realizados na Universidade Federal dos Vales do Jequitinhonha e Mucuri, Diamantina, MG. A viabilidade das sementes foi avaliada pelo teste de germinação e pelo teste de tetrazólio. O resgate das plantas foi realizado com ou sem o torrão, de acordo com o tratamento, sendo: T1: com torrão, sob sombreamento de 50%; T2: com torrão, sem sombreamento; T3: sem torrão, sob sombreamento de 50% e T4: sem torrão, sem sombreamento. O experimento de propagação vegetativa foi conduzido em delineamento casualizado em blocos com quatro tratamentos, sendo estes as diferentes doses de AIB (Ácido IndolButírico), em que: T1 = 0 ppm, T2 = 250 ppm, T3 = 500 ppm e T4 = 1000 ppm. Mesmo com o grau de umidade dentro do ideal (11%), observou-se baixa germinabilidade das sementes da espécie estudada (0,375%). De 800 sementes, 59 apresentaram viabilidade pelo teste de tetrazólio, porém, não germinaram, o que sugere que além da baixa viabilidade, as sementes de L. rigidus apresentam algum tipo de dormência, provavelmente a tegumentar. Ao final do período de avaliação, a sobrevivência média das plantas resgatadas foi de 67%. A maior mortalidade foi observada no substrato fibra de coco + vermiculita. A maior mortalidade de perfilhos de L. rigidus foi observada no tratamento com maior dose de hormônio. A espécie L. rigidus não se propaga eficientemente via sementes sendo, portanto, a propagação vegetativa é recomenda. PALAVRAS-CHAVE: Capim-arroz, restauração de áreas degradadas, Campo Rupestre, mineração, espécies nativas. RESEARCH AND SPREAD OF Lagenocarpus rigidus NEES
