O objetivo deste trabalho foi avaliar a eficiência da redução do espaçamento entre linhas e do uso de diferentes doses de nitrogênio em cobertura, utilizando como fonte a ureia. Para tal, avaliou-se a produtividade, componentes da produção e outras características agronômicas da cultura do milho. O experimento foi instalado na Estação Experimental da Cooperativa Agrícola Consolata (Coopacol) no município de Cafelândia, Paraná, em área de Latossolo Vermelho eutroférrico, conduzido em sistema de semeadura direta. O delineamento experimental utilizado foi em blocos casualizados, com quatro repetições, dispostos em parcelas subdivididas. Os espaçamentos entre linhas (0,45; 0,75 e 0,90 m) foram testados nas parcelas e as doses de nitrogênio em cobertura (0; 30;... |

The advantages of transplanting with respect to direct sowing has been widely reported in several vegetable species, but there are few studies in Cucurbits, and even fewer in summer squash (Cucurbita maxima (Carr.) Millán var. zapallito). Morphological and physiological characteristics of hybrid varieties determine earliness of between 5 to 10 days compared to traditional cultivars. The aim of the study was to compare the summer squash setting systems, direct sowing and nursery seedlings, and to determine their effect on yield and earliness in different genotypes. The hybrid varieties F1 Angelo and Espejo, and the standard varieties Any and Any Plus were used combined with two setting systems (direct sowing and nursery seedlings). Male and female flowering... |

Massive production, such as fish growing in water recirculation system, imposes challenges to animals capable of altering their homeostatic balance, and is able to affect their physiological performance. Therefore, the levels of ions and serum enzymes can be used as indicators of fish health. This study aimed to analyze the blood biochemistry profile of hybrid surubim (P. reticulatum X P. corruscans) submitted to different stocking densities in water recirculation system, in two distinct stages of production, from 150 to 400 g (first trial), and 400 to 1000 g (second trial). In the first trial, the five stocking rates were: 27.5, 47.5, 67.5, 87.5 and 107.5 fish/m³ of water. To obtain these densities, it was used 11, 19, 27, 35 and 43 fish per tank,... |

The relationship between pre-flowering climatic conditions and sugary disease incidence was quantified in grain and forage sorghum genotypes at two sowing periods (mid November and mid December). The trials were carried out over the 2001/02 and 2002/03 growing seasons, in Lages, Santa Catarina State. Four commercial male-fertile sorghum hybrids (BR 600-forrage, BR 700-grain, BR 701-forage/silage and BR 800-forage) and one male-sterile inbred line (BR 001-A) were evaluated. When each genotype reached the flowering stage, 50 panicles were marked and sprayed with a suspension of Claviceps africana (1,000 spores mL-1). Air temperature, humidity and rainfall were recorded through out the growing cycle. Low temperatures three to four weeks prior to flowering,... |

Chromosome numbers were counted in 126 new accessions of 50 Paspalum species from Brazil, Argentina, Paraguay and Bolivia. The chromosome numbers 2n=12, 20, 24, 30, 40, 50, 60, 80 were confirmed. Chromosome numbers for P. arenarium (2n=20), P. barretoi (2n=20), P. aff. ceresia (2n=40), P. corcovadense (2n=20), P. crispulum (2n=20), P. flaccidum (2n=40), P. nummularium (2n=20), P. scalare (2n=20), P. vescum (2n=20) and P. rectum (2n=20) and a diploid cytotype of P. malacophyllum are reported for the first time. The predominance of tetraploid accessions (43.6%) was confirmed, but an unusually high number of diploid species (44%) and accessions (35.7%) was found. These results open new perspectives for breeding programs, phylogenetic studies, and for research... |

Esta investigación consistió en formar híbridos entre diferentes cepas de Lentinula edodes que presentaran equivalentes o mejores resultados y características que sus cepas progenitoras, Se evaluaron 16 cepas de Lentinula edodes. Para después realizar cruzas DI-MON entre las cepas de Lentinula edodes y los monospóricos de la cepa CP-7, y cruzas MON-MON entre los monospóricos de la cepa CP-7 y CP-188. Para el crecimiento micelial en masters, los híbridos DI-MON [97] X [7]32, [189] X [7]11 y [95] X [7]11, fueron los más precoces. Para el crecimiento micelial en bolsas, las cepas CP-172, CP-174, CP-188*, CP-97, CP-189, CP-7*, CP-163 y el híbrido MON-MON [7]32 X [188]29, fueron los mas precoces.

ABSTRACT The commercial use of onion hybrids is preferred by producers. In contrast, the production of hybrid onion seeds is extremely inefficient. This is due to the use of lineages obtained by successive self-fertilizations assuming the effect of inbreeding depression per se. Therefore, it is necessary to understand new alternatives to reduce the effect of inbreeding depression in the strains. The objective of this study was to evaluate possible differences in polymorphism and levels of heterozygosity of strains obtained from intercrossed and self-fertilized plants. Twelve onion populations belonging to Bayer’s breeding program (Granex, IPA-1, IPA-2 and IPA-3) were used, obtained by self-fertilization of one plant, intercrossing of two plants or... |

ABSTRACT The eggplant is a highly valuable horticultural crop grown all over the world and it is of substantial economic importance in Asia. However, its production is severely threatened by several soil-borne and foliar diseases, insect-pests, drought, heat, and frost damage. Therefore, efforts to transfer useful resistance genes into eggplant from their wild relatives is important. In the present study, interspecific and intraspecific hybridization was carried out, that included three cultivated genotypes of eggplant (Solanum melongena MEE, Solanum melongena MEP, Solanum melongena MEB) and one wild Solanum species (Solanum incanum INC). The F1 hybrids were made by inter and intraspecific hybridization. A total of 632 possible inter and intraspecific... |

The first putative hybrid tree species of the genus Bruguiera (Rhizophoraceae), B. × rhynchopetala, is reported from mangrove forests of China and Australia. It was described from China previously as a variety of B. sexangula. The hybrid is acknowledged as B. gymnorhiza × B. sexangula with parent species restricted to different parts of the Indo-West Pacific. The hybrid is recognised at north-eastern and south-eastern parts of the overlap area between parent distributions, but it appears absent in western parts. Further local assessments are needed across the range. Hybrid status is supported by: 1) intermediate and shared morphological characters; 2) distribution limited to areas of co-occurrence of B. gymnorhiza and B. sexangula; and 3) molecular... |
