| ABSTRACT: Translocation of rare populations is regarded as the last resort for the conservation of species whose habitat destruction is imminent. The objective of the present study was to evaluate the effect of two height classes and three leaf reduction intensities on growth and increases in height, stem diameter, survival, and new leaf production in seedlings of Aspidosperma cylindrocarpon (peroba) obtained via rescue seedlings in a remnant of tropical semi deciduous forest. We recovered 240 individuals that were divided into two height classes (Class I-5 to 15cm and Class II-20 to 35cm) and subjected to three leaf reduction intensities (0%, 50%, and 100%), which were then transported to a shade house with 50% light reduction. Measurements of height,... |

| ABSTRACT Crambe has been studied as an option in crop rotation systems in order to provide raw material for biodiesel production. This study aimed to evaluate the effect of raising soil base saturation and addition of phosphorus (P) on the vegetative development, grain yield and oil content of crambe. The experiment was carried out in a Oxisol, arranged in factorial scheme (4 x 3), with 4 replicates (48 plots), in completely randomized blocks. Four base saturation levels (34 - natural of the soil, 40, 50 and 60%) and three P doses (0, 40 and 80 kg ha-1 of P2O5) were evaluated. The experimental plots formed a 9 m2 rectangle with 5 plant rows, spaced by 0.45 m, using the cultivar "Brilliant FMS". The evaluated variables were: dry matter of roots and shoots... |

| Este trabalho foi realizado com o objetivo de testar substratos obtidos a partir da combinação de um composto orgânico oriundo de resíduos do processo de fabricação de celulose, com um substrato base de controle. O estudo foi realizado no viveiro florestal da Universidade Federal de Lavras utilizando-se sementes do híbrido Eucalyptus “urograndis”. Foram testados seis tratamentos com doses crescentes de composto orgânico. O experimento foi implantado em delineamento inteiramente casualizado, com seis tratamentos, cinco repetições e 30 mudas por parcela. A avaliação dos substratos foi mensurada através da análise do crescimento das plantas, ao longo do tempo e de sua qualidade, ao final do processo de produção. Quanto às análises de crescimento e à qualidade... |
