The use of allometric equations in the estimation of the commercial volume of wood allows to plan the management Forestry In that sense, the objective in this work was to select the best allometric models to estimate the volume of wood in G. crinita trees, for this, trees between 13.09 m high and 10.58 cm DAP were used on average. For the determination of the best model, the highest adjusted coefficient of determination R2 (˃ R2Aj), lower coefficient of variability (˂ CV%) and lower Furnival index (IF) were considered. Of the 17 existing allometric models for forest species, two were suitable, the model: ln (V) = a + b ln (D) (R2 = 0.93, CV = 11.93%, IF = 0.003444) and the model that uses the combined variable Log: ln (V) = a + b ln (D2*H) (R2 = 0.91, CV = 11.93%, IF = 0.003444), likewise, a third model proposed in this study: ln (V) = a + b ln (D2) + c ln (D * H) - d ln (D2*H) (R2 = 0...

Objetivou-se com esse trabalho avaliar as características agronômicas de doze cultivares de melancia produzidas nas condições edafoclimáticas do cerrado de Roraima. O experimento foi desenvolvido no Campo Experimental Água Boa da Embrapa Roraima. O delineamento experimental foi em blocos ao acaso com quatro repetições e seis plantas por parcela. Os tratamentos consistiram das cultivares: Combat, Conquista, Verena, Congo, Magnum, Electra, Santa Amélia, Explore, Emperor, Crimson Select Plus, Charleston Gray Super e Omaru Yamato. Avaliaram-se as características produtivas, de sementes e de qualidade dos frutos. Concluiu-se que as condições edafoclimáticas do cerrado de Roraima favorecem as características produtivas e qualitativas dos frutos das cultivares de melancia analisadas. A maior produtividade foi encontrada no cultivar Crimson Select Plus, com média de 67848,25 kg ha...

Refrigeration is necessary to preserve the quality of watermelon fruits for longer, however, this technology is difficult to access and costly. Therefore, it is necessary to look for alternatives such as the selection of new varieties of watermelon that present good resistance to transport, superior fruit quality and high postharvest shelf life. In this context, the objective in this work was to evaluate the morphological, physicochemical and shelf life characteristics of the fruits of nine varieties of watermelon. It was conducted through a randomized complete block experimental design in a subdivided plot scheme. Nine varieties of watermelon were evaluated in the plots: Explorer, Magnum, Santa Amelia, Top Gun, Crimson Sweet, Electra, PX 397, Charleston Gray and Jubilee, and in the subplots five storage times: 0; 5; 10; 15 and 20 days. The edaphoclimatic conditions of the Amazon Savanna...
