| In the past two decades, Chile has developed intense mining activity in the Andes mountain range, whose altitude is over 4,000 meters above sea level. It is estimated that a workforce population of over 55,000 is exposed to high altitude hypobaric hypoxia. The miners work under shift systems which vary from 4 to 20 days at the worksite followed by rest days at sea level, in a cycle repeated for several years. This Chronic Intermittent Hypoxia (CIH) constitutes an unusual condition for workers involving a series of changes at the physiological, cellular and molecular levels attempting to compensate for the decrease in the environmental partial pressure of oxygen (PO2). The mine worker must become acclimatized to CIH, and consequently undergoes an acute... |

| La aclimatización es el periodo donde las plantas propagadas in vitro tienen cambios de ambiente, tipo de sustrato, entre otros factores controlados por el hombre, que determinan la sobrevivencia. Se evaluaron mezclas de materiales orgánicos (composta de cachaza y bagazo de caña de azúcar, suelo y turba) e inorgánicos (tezontle y agrolita) para determinar el porcentaje de sobrevivencia en la fase de aclimatización y crecimiento de plantas de Paulownia tomentosa propagadas in vitro. Las variables evaluadas fueron el porcentaje de sobrevivencia, altura de planta y formación de hojas, área foliar, longitud de raíz y tallo, relación raíz parte aérea, morfología de la raíz, peso de biomasa fresca y seca, concentración nutrimental del tejido vegetal y... |

| Resumo: Teve-se como objectivo avaliar o comportamento de características termorreguladoras, a condição corporal e a produção de leite no início da lactação de 45 cabras de diferentes tipos raciais (15 da raça Saanen, 15 cruzadas Sem Padrão Racial Definido (SPRD) x Murciana e 15 Alpinas Americanas). Foram tomadas a temperatura retal, a freqüência respiratória, o escore da condição corporal a produção diária de leite e as concentrações plasmáticas de triiodotironina (T3) e tiroxina (T4) avaliados até os 36 dias da lactação. As concentrações de T3 e T4 foram obtidas pelo método de radioimunoensaio. As variáveis meteorológicas foram registradas às 15 h, no mesmo horário da coleta dos dados fisiológicos. Os resultados obtidos indicaram que as cabras da raça... |

| ABSTRACT: The aim of the present study was to evaluate the effects of carbohydrate supplementation on the propagation of the orchid Cattleya schilleriana. The 120-d-old seedlings were subcultured in fructose-, glucose-, or sucrose-supplemented (0, 15, 30, and 45g L-1) ½ MS culture medium (half-strength macronutrient concentrations), using a completely random design with four repetitions per treatment. After 120d of treatment, root number and length, leaf number and length, and fresh weight were evaluated, and seedling survival was evaluated after 75d of acclimatization in a greenhouse. The in vitro growth data were submitted to regression analysis, whereas the percentage survival data were analyzed using ANOVA and Tukey’s test. Both in vitro growth and ex... |

| Stevia es un género de plantas fanerógamas perteneciente a la familia de las asteráceas, tiene 407 especies; una de sus especies es Stevia rebaudiana Bertoni, nombrada así por Moisés de Santiago Bertoni. Para el establecimiento in vitro de Stevia rebaudiana se aplicaron cinco tratamientos de desinfestación y se obtuvo al usar Cloro® (1.8 % cloro activo), Ridomil y Fungimycin previo a la siembra in vitro y al agregar al medio Cefotaxima (500 mgL-1) se obtuvo un porcentaje de contaminación de 50 % permitiendo una supervivencia de 47 %. En la inducción de callo se mostro que al combinar 1.5 mgL-1 2,4-D/AIA la capacidad de formación de callo del explante de hoja es de 25 %. El tratamiento de cinetina (1.3 gL-1) en el proceso micropropagación de Stevia mostro... |

| The thermolytic capacity test is used to assess the adaptability of animals to existing environmental conditions. However, there is insufficient information on the relationship between histomorphometry and adaptability of buffaloes. Thus, this study aimed to assess the use of thermolysis pathways by buffaloes reared in a hot and humid environment so as to understand the relationships between environment, skin morphological characteristics, and heat storage, as well as the intensity and proportionality of use of its ways of dissipating heat to maintain homeothermy. The heat tolerance test, associated with the evaluations via infrared thermography, was applied to 10 female Murrah buffaloes and tegument histomorphometry was carried out. The animals exhibited... |

| The effect of arbuscular mycorrhizal fungi (AMF) on micropropagated banana plantlets was evaluated during the acclimatization period. Plants were inoculated with Acaulospora scrobiculata, Glomus clarum or Glomus etunicatum. After cultivation in a greenhouse for 3 months, height, leaf area, fresh weight and dry matter of root and shoots, level of AMF colonization, nutrient level, photosynthesis and transpiration rate, water potential and stomatal conductance were measured. The number of AMF spores produceded in each treatment was also determined. Plantlets inoculated with Amf had greater height, leaf area and fresh weight of shoots and roots, as well as higher rates of photosynthesis and transpiration than controls. Plants inoculated with Glomus were... |

| The rhizomes of Zingiber officinale Roscoe (ginger) are widely used for their medicinal and flavoring properties, whereas the influence of root symbionts on their growth is poorly understood. In this study, the effects of phosphate fertilization and inoculation with a mixture of arbuscular mycorrhizal fungi (AMF) (isolates Glomus clarum RGS101A, Entrophospora colombiana SCT115A and Acaulospora koskei SPL102A) on survival, growth and development of micropropagated ginger were investigated. After transplanting to post vitro conditions, the ginger microplants were subjected to the following treatments: a) AMF mixture, b) P addition (25 mg kg-1), c) AMF + P, and d) non-mycorrhizal control without P addition. After eight months of growth, survival ranged from... |

| Eight substrates were evaluated for ex-vitro establishment of Phalaenopsis amabilis seedlings. They were: Fibraflor® (commercial substrate), Turfa Fértil FG2® (commercial substrate), vermiculite, coconut fiber from the pericarp, decomposed pine bark, organic compost, sphagnum and shredded xaxim, in the establishment of seedlings of Phalaenopsis amabilis L., in combination, with and without immersion of the seedlings, after they were removed from the growth flasks, in Manzate 800 at a dosage of 1 g L1. The evaluated parameters were: the sum of the lengths of the two largest leaves, the sum of the lengths of the three largest roots and the percentage of surviving seedlings, evaluated at 190 days after planting. It was observed that there were... |

| O objetivo deste trabalho foi avaliar a influência da aclimatação, da intensidade de geada e da disponibilidade hídrica sobre os danos causados pela geada em trigo. Os experimentos foram conduzidos em telados, com trigo cultivado em vasos. A aclimatação e a incidência de geada foram simuladas em câmaras de crescimento. Os fatores abióticos avaliados foram: regimes de aclimatação (com e sem); gradiente de temperatura (2, -2, -4 e -7°C); e variação de disponibilidade hídrica no solo, antes da geada (9, 6, 3 e 1 dia sem irrigação). Todos os fatores foram avaliados no afilhamento, alongamento e espigamento das cultivares: BR-18 Terena, mais tolerante à geada; e BRS 194, menos tolerante. As variáveis avaliadas foram: grau de queima de folhas, sete dias após a... |

| While research on ocean acidification (OA) impacts on coral reefs has focused on calcification, relatively little is known about effects on coral photosynthesis and respiration, despite these being among the most plastic metabolic processes corals may use to acclimatize to adverse conditions. Here, we present data collected between 2016 and 2018 at three natural CO2 seeps in Papua New Guinea where we measured the metabolic flexibility (i.e. in hospite photosynthesis and dark respiration) of 12 coral species. Despite some species-specific variability, metabolic rates as measured by net oxygen flux tended to be higher at high pCO2 (ca 1200 µatm), with increases in photosynthesis exceeding those of respiration, suggesting greater productivity of... |
