The Fertigation is the combined application of water and nutrients to a crop. It can be adapted to all types of agricultural crops. The objective of this study was to evaluate the effect of urea concentration in irrigation water on electrical conductivity of the soil solution and saturation extract along the first cycle of banana cv. Terra Maranhão. The experiment followed a completely randomized design with six treatments and ten replications. Treatments regarded for using three urea concentrations (1.0; 2.5 and 4.0 g L-1) in irrigation water applied by two micro irrigation systems (microsprinkler and drip). Results showed that there was a linear elevation of electrical conductivity of saturation extract and soil solution with the increase on concentration of urea in the injection solution. Urea should be used under concentrations up to 2.5 g L-1 in irrigation water without causing increase on electric conductivity of soil solution and saturation extract, considering 1.1 dS m-1 as the tolerated value for the crop. Nitrate in the soil solution increased significantly with the increase of urea concentration in the injection solution. The maximum concentration of nitrate in the soil occurred for 4,0 g L-1 concentration of the injection solution. |

Morphoanatomical characterization of the stigma of different species has provided important data for the taxonomy of Bromeliaceae. Stigma receptivity is fundamental for the effectiveness of reproduction in plants, and the production of hybrids by controlled pollination. This study aimed to characterize stigma morphoanatomy of 18 Bromeliaceae species, from five genera, by means of light and scanning electron microscopy, and to determine the stigma receptivity of these species. The species investigated were: Aechmea bicolor, Aechmea bromeliifolia, Aechmea distichantha, Aechmea fasciata, Aechmea nudicaulis, Ananas sp., Ananas ananassoides, Ananas bracteatus, Ananas lucidus, Ananas parguazensis, Alcantarea nahoumii, Pseudananas sagenarius, Vriesea carinata, Vriesea friburgensis, Vriesea michaelii, Vriesea paraibica, Vriesea simplex and Vriesea unilateralis. Three methods were used comparatively to determine stigma receptivity during floral opening: hydrogen peroxide, benzidine and ?-naphthyl acetate. Two stigma types were observed: conduplicate-spiral in Aechmea, Ananas, Alcantarea and Pseudananas and convolute-blade in Vriesea. The stigma is trifid, formed by a unistratified epidermis, parenchyma with numerous idioblasts containing raphides, and three vascular bundles, one for each carpel. In the conduplicate-spiral stigmas type, the inner epidermal cells contain dense cytoplasm and a prominent nucleus, a characteristic not observed in the convolute-blade stigmas type. The stigmatic papillae vary according to species, as well as the presence of an ornamented cuticle. The longest pistil length was observed in A. nahoumii (91.75 mm) and shortest in A. bromeliifolia (4.19 mm). Higher stigma receptivity is observed at anthesis for the species studied, with the highest receptivity at 8 am and remaining receptive until noon, with the exception of V. unilateralis, for which the greatest receptivity was observed at midnight and extended until dawn. The use of ?-naphthyl acetate was the most efficient methodology for the detection of stigma receptivity, and to identify the receptive areas of the stigma.
