| Jatropha curcas L. is a versatile crop since all its plant material is brought to use either as energy source, industrial or medicinal purpose. Several studies are ongoing in different parts of the world to optimize, enhance and exploit the growth, fruiting cycle and different developmental stages of the plant so that the economic yield of the plants can be utilized to the fullest limits. Foliar application of plant growth regulators such as ethrel (an ethylene releasing compound), indole acetic acid (IAA) and naphthalene acetic acid (NAA) at 50, 100 and 150 ppm, was found to influence different morpho-physiological characters in Jatropha curcas L, such as plant height, collar diameter, tree spread, flower initiation, number of inflorescence per plant,... |

| Com o objetivo de avaliar o comportamento silvicultural e a produtividade de genótipos de pinhão manso sob condições irrigadas no Semiárido nordestino, um experimento foi implantado na Fazenda Gabriela, localizada no Município de Santa Maria da Boa Vista, Pernambuco (PE). Usou-se o delineamento de blocos ao acaso com 10 tratamentos e três repetições. Os tratamentos constaram de 10 genótipos obtidos da seleção de plantas mais produtivas de um plantio introdutório de pinhão manso em Petrolina-PE. O espaçamento utilizado foi de 3,0 x 2,0m. Cada planta, por ocasião do plantio, foi adubada com 150g de NPK - fórmula 06:24:12. As plantas foram irrigadas semanalmente por gotejamento. Os resultados obtidos aos três meses de idade foram submetidos à análise de... |

| The objective of this research was to evaluate the effect of three concentrations (3, 6, and 9%) of forage turnip (Raphanus sativus) and physic nut (Jatropha curcas) cakes on dry matter, crude protein, ether extract, neutral detergent fiber, acid detergent fiber, lignin, acid detergent insoluble nitrogen neutral detergent insoluble nitrogen contents, in vitro dry matter digestibility, pH values and concentrations of N-NH3 in elephant grass silages. It was used an entirely randomized design in factorial arrangement [(2×3)+1]. Experimental PVC silos were used and ensiled material was kept for 62 days. The addition of cakes increased the dry matter contents (P<0.05). The fibrous fractions were reduced (P<0.05) with the inclusion of cakes during the... |

| In spite of increasingly widespread interest in planting physic nut, breeding efforts are still in its infancy. In that context, an important resource recently established aiming future breeding efforts was the assembly of a germplasm bank with near 200 accessions. The objective of this study was to estimate genetic parameters, repeatibility coefficients and genetic correlation between seven traits, measured in 110 accessions (half sib families) of this germplasm bank in different stages of development. The results show that higher relative values of additive variance were only found for yield and height, and the existence of low environmental variation (either of temporary or permanent nature) among plots within blocks. Given the high repeatibility values... |
