“…In this area, other bamboo species can be used instead of B. vulgaris. Sanquetta et al (2015) highlighted that the B. oldhammii species has a higher drought tolerance than B. vulgaris, which can be used for food and woody peaks. Further analysis is required to understand how bamboo adapts during the dry period, such as leaf area reduction, and to determine the biomass production volume, which correlates with evapotranspiration (Piouceau et al 2014).…”

Bamboo has a huge potential for several uses; however, there are many species with numerous climatic growth requirements. This makes it difficult to characterize the agro-climatic bamboo demands, in order to define areas suitable for its cultivation. This study aimed to quantify the bamboo agro-climatic requirements, as well as to define areas suitable for growth in the central-north region of the Brazilian Savannah. The agro-climatic requirements were defined from averages of the center of origin of the Bambusa vulgaris species, in southwest Asia. The climatic characterization was based on the daily mean, minimum and maximum air temperature, annual rainfall and water deficit, and consecutive months with a rainfall rate lower than 40 mm. These limits were used to define suitable, marginal and unsuitable regions. The optimal range was between 15.14 ºC and 35.33 ºC for mean air temperature, with a lower limit of 12.07 ºC and a higher limit of 38.83 ºC, respectively, for minimum and maximum air temperature. The annual minimum rainfall required was 775 mm, with a maximum annual water deficit of 1,320 mm, and a maximum of eight consecutive months with rainfall of less than 40 mm. Most of the studied region was classified as suitable (74 % of the total area), followed by marginal due to water deficit (12.9 %), unsuitable (8.9 %) and marginal due to air temperature (4.2 %).

“…There are around 75-90 genera and 1,100-1,250 species of bamboo (Manhães 2008, Sanquetta et al 2015. They occur naturally in all continents, except for Europe and Antarctica, in different climatic conditions (Scurlock et al 2000).…”

In plant micropropagation, the establishment stage is difficult, due to the presence of microorganisms in tissues from field-grown matrices, especially for bamboo. This study aimed to establish an efficient asepsis protocol for Bambusa oldhamii explants from field plants, as well as to carry out the molecular identification of a possible endophytic bacterial isolate. The explants were exposed to 70 % alcohol, 1 % sodium hypochlorite (NaOCl), 0.1 % mercuric chloride (HgCl2), thiophanate-methyl (Cercobin®) and chlorhexidine digluconate (2 % Riohex®) in different combinations, and introduced into Murashige and Skoog culture medium (solid or liquid), supplemented or not with 4 mL L-1 of Plant Preservative Mixture (PPMTM), totaling seven treatments. The asepsis and immersion of the explants in the liquid culture medium containing 4 mL L-1 of PPMTM visually inhibited the bacterial and fungal growth, allowed the development of shoots with a mean length of 2.2 cm and posterior subcultures, being the best treatment used for the in vitro establishment of B. oldhamii. The molecular identification of an endophytic bacterium performed by 16S rDNA sequencing allowed to identify the bacterial isolate as Ralstonia sp., with 100 % of similarity, and the phylogenetic analysis grouped it with Ralstonia pickettii. In addition, the bacterial isolate showed to be sensitive to 4 mL L-1 of PPMTM by the minimum inhibitory concentration test.

“…O bambu tem como grande potencial a sua produtividade (MOGNON et al, 2014;SANQUETTA et al, 2015). No Brasil, se reconhece a alta produtividade de biomassa de bambu, porém na prática ainda possui baixo reconhecimento quanto ao seu potencial de utilização (GUARNETTI; COELHO, 2014 A termogravimetria (TG) é uma das técnicas mais utilizada para investigar e comparar os eventos térmicos que ocorrem durante o processo de decomposição de biomassa, estabilidade térmica e quantidade de massa residual (SANTOS et al, 2012).…”

Rafaela Faber de Campos[1]Pedro Henrique Weirich Neto[2]Sandra Regina Masetto Antunes3Maria Elena Payret Arrúa4 RESUMOA biomassa sempre foi uma das fontes de energia mais utilizadas pelo homem, e como consequência, principalmente, dos problemas enfrentados pelo uso de combustíveis fosseis assume, novamente, grande importância. Vários tipos de biomassa podem ser citados, como por exemplo, a madeira de árvores, entretanto nem sempre é a mais adequada para geração de energia. O bambu entre outras plantas apresenta estrutura ímpar e, se destaca pela produtividade, podendo-se tornar uma alternativa sustentável para a geração de energia. Neste trabalho foi investigada a estabilidade térmica, consequentemente, a degradação térmica de quatro espécies de bambu in natura e na forma de carvão utilizando a termogravimetria (TGA). As espécies avaliadas foram Phyllostachys aurea A. C. Rivière (bambu dourado), Chusquea gracilis McClure & Smith (criciúma), Chusquea mimosa McClure & Smith (caratuva) e Merostachys multiramea Hackel (taquara lixa), presentes no centro-sul do estado do Paraná - Brasil. A análise dos resultados de termogravimetria indica que a decomposição destas espécies de bambu ocorre em 3 etapas. Estas etapas são associadas a perda de umidade (primeira), decomposição da hemicelulose e celulose (segunda) e decomposição da lignina (terceira). As espécies se diferenciam na temperatura de velocidade máxima de decomposição devido, provavelmente, às suas distintas composições.
