Crescimento de mudas micropropagadas de bananeira aclimatizadas nas condições da Amazônia Sul Ocidental sob a influência de diferentes substratos e recipientes Growth of micropropagated banana plantlets acclimatized on conditions of South West Amazon under the influence of different substrates and recipients

Para laboratórios que produzem milhares de plantas micropropagadas regularmente, a otimização da fase de aclimatização é de fundamental importância para evitar perdas excessivas de plantas, bem como favorecer seu crescimento. O trabalho teve por objetivo avaliar o crescimento de mudas micropropagadas de bananeira na aclimatização, sob a influência de diferentes substratos e recipientes, nas condições da Amazônia Sul-Ocidental. Após o sexto subcultivo, brotações de bananeira, cv. Grand Naine (AAA), foram enraizadas em meio MS básico sendo, posteriormente, transferidas para viveiro onde foram plantadas em tubetes de 115 cm³ e 180 cm³ preenchidos com seis diferentes substratos, formulados a partir da combinação de terra de encosta, esterco bovino e casca de arroz carbonizada. Avaliações sobre sobrevivência, altura da parte aérea e diâmetro do pseudocaule foram realizadas quinzenalmente, sendo que, ao final de 75 dias, também foi determinada a massa fresca e seca das plantas. Observou-se que a sobrevivência das plantas não foi influenciada pelo uso de tubetes de 115 cm³ ou 180 cm³, no entanto, plantas aclimatizadas em tubetes de 180 cm³ apresentam maior crescimento em altura e diâmetro do pseudocaule e, conseqüentemente, maior acúmulo de massa fresca e seca das partes aérea e raízes, durante a aclimatização, quando comparados aos tubetes com 115 cm³ de capacidade. Entre os substratos, verificou-se que aqueles que continham esterco bovino na sua composição, proporcionaram resultados superiores quando comparados aos demais substratos testados para todas as variáveis analisadas, sendo este, portanto, um importante componente no desenvolvimento das plantas durante a fase de aclimatização.<br>For laboratories that produce thousands of micropropagated plants regularly, the optimization of the acclimatization phase is of fundamental importance to avoid excessive losses and to promote the development of the plants. The aim of this work was to evaluate the growth of micropropagated banana plantlets during the acclimatization under the influence of different substrates and recipients on conditions of South West Amazon. Shoots of banana, cv. Grand Naine, were rooted in MS medium, being the rooting plants transferred to a nursery, in two types of plastic dibble tubes (115 cm³ and 180 cm³) and six different substrates formulated from different portions of soil, carbonized rice hulls and bovine manure. Evaluations of plant survival, height of the aerial part and pseudostem diameter were carried out each fifteen days, and at the end of 75 days, fresh and dry mass for the roots and aerial parts of the plants were also determined. It was verified that the plant survival was not influenced by the use of the 115 cm³ or 180 cm³ plastic dibble tubes. However, acclimatization accomplished in the 180 cm³ plastic dibble tubes provided larger growth in height and pseudostem diameter of the plants and, consequently, larger accumulation of fresh and dry mass of roots and aerial parts, when compared to the 115 cm³ plastic dibble tubes. Among the substrates, it was observed that bovine manure was fundamental as substrate component to obtain the best results

Guidelines for the use of flow cytometry and cell sorting in immunological studies (second edition)

These guidelines are a consensus work of a considerable number of members of the immunology and flow cytometry community. They provide the theory and key practical aspects of flow cytometry enabling immunologists to avoid the common errors that often undermine immunological data. Notably, there are comprehensive sections of all major immune cell types with helpful Tables detailing phenotypes in murine and human cells. The latest flow cytometry techniques and applications are also described, featuring examples of the data that can be generated and, importantly, how the data can be analysed. Furthermore, there are sections detailing tips, tricks and pitfalls to avoid, all written and peer-reviewed by leading experts in the field, making this an essential research companion
