Objetivou-se avaliar importância relativa de caracteres para a diversidade genética pela técnica dos componentes principais entre híbridos de Panicum maximum. O experimento foi constituído de três populações, sendo a progênie 1 resultante do cruzamento entre a planta sexual S10 e o capim tanzânia, a progênie 2, proveniente do cruzamento entre a planta sexual S10 e o capim-mombaça e a progênie 3 resultante do cruzamento entre a progenitora sexual S12 e o capim-tanzânia. As
características morfológicas comprimento da lâmina, largura da lâmina, altura da planta e diâmetro da touceira foram utilizadas na análise dos componentes principais. Para as progênies 1 e 3, as características de maior peso nos últimos autovetores são comprimento e largura da lâmina, sendo estas características altamente correlacionadas com a altura da planta e comprimento da lâmina, respectivamente. Para a progênie 2, as características de maior peso nos últimos autovetores são altura da
planta e diâmetro da touceira. A característica morfológica comprimento da lâmina, de maneira geral, é a que menos contribui para os estudos de diversidade genética entre híbridos de Panicum maximum. |

There has been considerable excitement recently over the use of conducting polymers in a variety of technological applications. Some of the applications have already been commercialized, as in the case of rechargeable batteries, conductive textiles, and electrical display. Sophisticated long-term applications are also envisaged for these materials, including the fabrication of molecular electronics devices, that is, devices in which switching and memory phenomena would be controlled at the molecular level. Two main requiremos must be met to achieve such an ambitious goal. First development of the ability to construct structures whouse molecular architecture could be manipulated and appropriately designed. Such structures are most likely to consist of ultra-thin films. Two techniques are available for this purpose, namely the Langmuir-Blodgett (LB) method, which has been investigated extensively for several yearls, and the more recent Self Assembly (SA) technique for building multilayers. These techniques allow the fabrication of ultra-thim (of the order of nm) in the form of multilayers with a high degree of control of orientational order in the case of the LB films, The second requirement concerns the acess to individual molecules. Though substantial research must be carried out before this requirement can be met, the progesss reported in the use of atomic force microscopy (AFM) and scanning tunneling microscopy (STM) on molecular system is most encouraging. It is now possible to image monolayers of simple molecules on graphite and also to probe and manipulate individual molecules at surfaces. We are concerneed with the first of the above-mentioned aspects, focusing on the LB technique that has been exploited worldwide for fabricating ultra-thim films of a variety of materials, including conducting polymers. Because the formation of LB films requires the spreading of a monolayer onto an aqueous subphase, some prerequisites must be fulfilled by the material of interest. It must be soluble in a reasonably volatile organic solvent and also sufficiently surface for spreading to occur. The conducting polymers that were first investigated, namely polyacetylene, polypyrrole, polythiophene, and polyaniline, could not be processed in this manner, and therefore several atrategies were developed for overcoming this difficulty. An overview of these strategies will be provided below, following a brief introduction to LB films. Recent developments on the LB films from polyanilines will then be discussed, followed by a description of the most important properties and some of the possible appications that have been demonstrated for LB films of conducting polymers.
