In the Brazilian wet and dry seasons, common beans (Phaseolus vulgaris L.) are grown under rainfed conditions with unexpected episodes of drought and high temperatures. The objective of this study was to evaluate the physiological mechanisms associated with drought adaptation traits in landraces and line/cultivars of beans from the Andean and Mesoamerican gene pools. Twenty-five genotypes, contrasting in terms of drought tolerance, were evaluated in a phenotyping platform under irrigated and rainfed conditions. Agronomic and physiological parameters such as grain yield, shoot structures, gas exchange, water potential, and osmotic adjustment were evaluated. The stress intensity was estimated to be 0.57, and the grain yield reduction ranged from 22 to 89%. Seven accessions, representative of the Andean and Mesoamerican germplasm (CF 200012, CF 240056, CF 250002, CF 900004, CNF 4497, CNF 7382, and SEA 5), presented superior performance in grain yield with and without stresses. The physiological responses under abiotic stresses were highly variable among the genotypes, and two Mesoamerican accessions (CF 200012 and SEA 5) showed more favorable adaptive responses. As the main secondary physiological traits, gas exchange and osmotic adjustment should be evaluated together with the grain yield to increase the selection efficiency of abiotic stresses-tolerant common bean lines. |

Abstract: This study aimed to evaluate the physiological parameters, the productive characteristics, structural and chemical composition of Megathyrsus maximus (syn. Panicum maximum) cultivars BRS Massai and BRS Tamani submitted to different periods of deferment and moments of use. The experimental design was randomized complete block design in a factorial scheme 2 x 2 x 3, being two grass cultivars (Massai grass and Tamani grass), two deferment periods (rainy season and dry-rainy transition) and three sealing times (40, 80 and 120 days). Both cultivars had higher leaf transpiration rate when used for 40 days of deferment (0.63 μmol/m2/s). It was observed that the cultivar BRS Massai presented higher photosynthetic rate (P<0.05) to 40 days of deferment (1.10 μmol/m2/s), higher rate of production and forage accumulation when used for 40 days. On another side, there was a greater efficiency in the use of water during the period of transition in the pastures sealed for 80 and 120 days (64.60 and 62.30 kg DM/ha/mm, respectively). A reduction (P<0.05) of total digestible nutrients (TDN) and crude protein (CP) was observed with the increase in pasture sealing time. In general, the deferment in the transition period allows the use of forage without greater productive and nutrient losses up to 80 days of sealing for the cultivar BRS Tamani and up to 40 days for BRS Massai. [Trocas gasosas, características produtivas e composição química de gramíneas tropicais diferidas I: cultivares BRS Massai e BRS Tamani]. Resumo: Objetivou-se avaliar os parâmetros fisiológicos, as características produtivas, estruturais e composição química de Megathyrsus maximus (syn. Panicum maximum) cultivares BRS Massai e BRS Tamani submetidas à diferentes períodos de diferimento e momentos de utilização. Utilizou-se o delineamento de blocos completos casualizados, em esquema fatorial 2 x 2 x 3, sendo duas cultivares de gramíneas (capim-massai e capim-tamani), dois períodos de diferimento (período chuvoso e transição chuvoso-seco) e três tempos de vedação (40, 80 e 120 dias). Ambas as cultivares tiveram maior taxa de transpiração foliar quando utilizadas aos 40 dias de diferimento (0,63 μmol/m2/s). Observou-se que a cultivar BRS Massai apresentou a maior taxa fotossintética (1,10 μmol/m²/s), taxa de produção e acúmulo de forragem quando utilizada aos 40 dias de diferimento (P<0,05). Por outo lado, houve maior eficiência no uso da água durante o período de transição nos pastos vedados por 80 e 120 dias (64,60 e 62,30 kg de MS/ha/mm, respectivamente). Observou-se redução (P<0,05) dos nutrientes digestíveis totais (NDT) e proteína bruta (PB) com o aumento no tempo de vedação das pastagens. De modo geral o diferimento no período de transição possibilita a utilização da forragem sem maiores perdas produtivas e nutritivas até os 80 dias de vedação para a cultivar BRS Tamani e até os 40 dias para a BRS Massai.
