| The present study aimed to evaluate the dimensional variation of axial tracheids along the stem of Sequoia sempervirens Endl (Lamb.). Three trees with approximately 18 years old were selected, of which six discs were removed from along the height. Of each disk, three samples were taken from the vascular cambium to the medulla. For each sample we proceeded to measure the individual characteristics of tracheids. As a procedure of analyzing the results, we applied the Tukey test at 95% probability. The results indicated that the values for the characteristics of tracheids resemble those reported in the literature for the genus Pinus or species belonging to Gymnosperms, except the cell wall thickness, whose values were high. Regarding the variation of... |

| Sugarcane is one of the important commercial crops cultivated world-wide both under tropical and sub-tropical conditions. The crop gains economic importance by virtue of its industrial potential in terms of products like crystal white sugar, bagasse, pressmud, power etc. Among the various production constraints of the crop, diseases are seen as a major threat for sustaining the productivity of sugarcane. Conventional Breeding is a lengthy process and it involves almost more than 10 years for the release of a commercial variety. Many varieties with superior agronomical traits have succumbed to diseases like red rot and smut during the course of cultivation, which hitherto at the time of release were rated to be resistant. The breakdown of disease resistance... |

| The identification of genus and species is made by systematic, by noticing morphological and anatomical characteres which were the phenotype expression. However, changes in one or more gene bases can result in phenotypes similarities between different species, inducing an identification error. Alternatively, molecular appliances based in mithocondrial and ribosomal genes appeared. This study aims to compile information about the molecular identification and present the South American Catfish (Rhamdia quelen) case, for which there is controversy generated by taxonomy identification. The different genes used to identification have their particularities, like insertions and deletions on the case of 16S rRNA and the 18S rRNA. Besides these ribosomal genes,... |

| The aim of this study was verify the drying rate and the wood quality from Hovenia dulcis, subjected to three drying processes (45, 60 and 75 ºC ). This way, 45 boards with the followings dimensions were used: 25 x 100 x 500 mm. These boards were dried until reach a moisture of 10%. The defects were quantified using a caliper, measuring the maximum deformation in the middle or in an extremity of the piece, depending on the type of defect. The results showed that the drying rate until 30% was greater than the others were and increased with higher temperatures, except for the 45 ºC process, not only in the hygroscopic stage but also from green condition to 10% of moisture. Although some warps have happened, the values were lower than those ones admitted by... |

| The grapevine propagation is usually made using grafting directly in the field, on rootstocks planted the previous year in situ, or rooted in the nursery. In this process the change takes about two years to be formed. Given the above, the aim of the present work in advance to obtain grapevine plants in grafting times and root induction through basal heating. As rootstock used the grapevine hybrid ‘Riparia’ x ‘Rupestris 101-14’ and the cv. ‘Niagara Branca’. The experimental design was a randomized complete block, in a 3x5 factorial scheme, containing four replications, and resulted from two factors, with factor A, consisting of three pre-treatments for rootstock cuttings (control = A1, humid = 24 hours in water = A2 and 2000 mg L-1 of AIB in hydroalcoholic... |
