| Piper aduncum L. (Piperaceae) es una especie arbustiva umbrófila que se encuentra generalmente en suelos con elevado contenido de materia orgánica y humedad. De las hojas se extrae aceite esencial con acción insecticida, fungicida y bactericida, con una amplia utilización en el sector agrario y medicinal. El objetivo del trabajo fue caracterizar el limbo de P. aduncum. Se efectuó la caracterización anatómica e histoquímica de la sección transversal y la caracterización anatómica de la sección paradérmica apical, mediana y basal del limbo. Para ello las hojas fueron preparadas con las técnicas tradicionales de microscopía de luz y microscopía electrónica. El mesófilo es dorsiventral con capas subcelulares en ambas epidermis. En la epidermis y las capas... |

| ABSTRACTOil palm is one of the most economically valuable oil seed plants, but the expansion of plantations has been limited by availability of seedlings, as the conventional propagation is through seeds, which have low germination rates. One possible solution for the large-scale production is the use of somatic embryogenesis. The aim of this study was evaluate the effects auxins 2,4-D and picloram on the induction of pro-embryogenic masses inE.guineenesis hybrid leaf explants and characterize, regarding embryogenic characteristics, with cytochemical and ultrastructural analisys. Specifically, in vitro plantlets leaves fragments were inoculated in Y3 culture medium supplemented by 2.4-D or picloram at different concentrations (0.0, 1.0, 3.0, 6.0 and 9.0 mg... |

| ABSTRACT The purpose of this investigation was to determine the influence of colored shade nets on the growth, anatomy and essential oil content, yield and chemical composition of Pogostemon cablin. The plants were cultivated under full sunlight, black, blue and red nets. The harvesting was performed 5 months after planting and it was followed by the analysis of plant growth parameters, leaf anatomy, essential oil content, yield and chemical composition. The plants grown under red net have produced more leaf, shoot, total dry weight and leaf area. Plants cultivated under colored nets showed differences in morphological features. Plants maintained under red net had a higher leaf blade thickness and polar and equatorial diameter of the stomata ratio.... |
