The preparation of lists from the obtaining of primary data in herbaria contributes to enrich knowledge about the Brazilian flora. Mainly, for botanical groups present in the region semiarid and characterized by low availability of information as the monocotyledons. In this way, this work presents a floristic survey of monocotyledons of the State of Ceará, northeast of Brazil, analyzing the taxa richness. The data, which are computerized and available in the software BRAHMS 6.7, were obtained from collecting of the Herbarium Prisco Bezerra (EAC). A total of 3,472 exsicates from collections in the State of Ceará were analyzed, representing 540 species, 207 genera and 28 families. The richest families were: Poaceae (193 spp.), Cyperaceae (104 spp.), Orchidaceae (51 spp.), Bromeliaceae (38 spp.) and Araceae (35 spp.). The richest genera were: Cyperus (31 spp.), Paspalum (26 spp.), Panicum (23 spp.), Rhynchospora (17 spp.), Eleocharis (16 spp.) and Eragrostis (13 spp.).

This study was carried out in three irrigated West indian cherry varieties at Petrolina - PE, Brazil, in 2006 and 2007, with the objective of comparatively knowing the floral biology, the reproductive system, the effective pollinators, their habit of visiting the flowers and the contribution of pollination to crop benefit. The floral anthesis was diurnal and occurred between 4.30h and 5.00h, and at this moment the pollen grains were already available and the stigma was receptive. The number of elaiophores varied among the varieties and individuals. The pollinic viability of the variety Okinawa was low (14.8 ± 5.5%) when compared to Flor Branca and (92 ± 3%) and Sertaneja (83.4 ± 9.2%) varieties. The reproductive success due to spontaneous selfpollination varied from 4 to 6% among the three varieties. In the manual crossed pollination among the varieties, the lower fructification tax was obtained for the crossing using Okinawa as pollen donor (<1%) and the major rate was obtained with Sertaneja (43%). In the natural pollination (control) Sertaneja presented the biggest value of fructification (46%). The variety Okinawa showed the lowest frutification rates. The irrigation system adopted in the farming systems influenced the visits of the pollinators. Regarding frequency, behavior and flower constancy, Centris aenea was considered effective pollinator of the crop in the region.

This research aimed at evaluating the effect of the semiarid climatic conditions on the physiological behavior of F1 Saanen x Boer crossbred goats, created at an intensive system. The experiment was carried out in the Health and Rural Technology Center, in the Federal University of Campina Grande, in the town of Patos, Paraiba. Twenty-four animals were used, with ages varying between three and four months, being 12 females and 12 males, weaned and prevented against worms, receiving ad libitum water and controlled concentrate and roughage. The environmental variables were checked inside and outside the experiment place, as well as the physiological variables of all animals. Except for the humid bulb temperature, the variance analysis revealed shift effect (P<0.05) for all environmental variables. There was merely shift effect (P<0.05) for Cardiac Frequency and Rectal Temperature, and the averages of both, in the afternoon, overcame those observed in the morning. The obtained results based on the studied physiological and environmental variables conclude that crossbred goats, resulting of Boer (paternal) and Saanen (maternal), present a good resistance to heat, permitting their indication for the meat production in confinement on semiarid conditions.

Water is a limiting factor for crop yields, for example yellow passion fruit, requiring from use of irrigation due to limitation of surface waters. This study aimed to evaluate irrigation levels and fruits quality in yellow passion fruit production in Semiarid conditions, thus an experiment was carried out. The seedlings were grown in greenhouse and transplanted in the field spacing 4 m x 2 m. The treatments studied were five water levels: 60; 80; 100; 120 and 140% from ETo, applied through drip irrigation with 4 repetition. The parameters evaluated were average fruit weight (g), yield (t ha-1), the pulp yield with seed (%), juice yield (%) and skin percentage (%). The results obtained in the experiment showed that the highest yield of hybrid passion fruit with average weight over 150 g, and the highest yield was obtained with the blade of 120% ETo. The yield of pulp with seeds was negatively affected by increased volumes of water for irrigation. Can use plant 120% ETo for the irrigation of yellow passion fruit 'IAC 273/277¿ to optimize production and improve fruit quality in semiarid conditions.

O objetivo deste trabalho foi analisar a uniformidade de aplicação de efluente de três sistemas de irrigação abastecidos com diferentes características de esgoto doméstico do condomínio residencial Bosque Acamari, em Viçosa-MG. O experimento foi realizado em área de pesquisa da Universidade Federal de Viçosa (UFV), em Viçosa-MG. Montaram-se três sistemas de irrigação por gotejamento, abastecidos com esgoto doméstico preliminar (EDP), esgoto de tratamento secundário (EDS) e esgoto de tratamento terciário (EDT). Cada sistema de irrigação foi composto por filtro de discos e gotejadores não autocompensantes com vazão nominal de 1,7 L h-1. A uniformidade de aplicação de efluente foi obtida a cada 100 h, totalizando 500 h de operação, com os Coeficientes de Uniformidade de Distribuição (CUD) e de Uniformidade Estatística (Us). Foram realizadas determinações físico-químicas e microbiológicas nos esgotos domésticos. Conclui-se que as características ferro total e coliformes totais representam risco severo de obstrução para gotejadores abastecidos com EDP, EDS e EDT, enquanto para as características manganês total, magnésio e cálcio tal risco é baixo. A formação de biofilme de sólidos suspensos e bactérias foi a principal causa de obstrução de gotejadores. Os valores de CUD e Us apresentaram, após 500 h de operação, redução de 61 e 54%; 27 e 24%; e 57 e 59%, respectivamente, para os sistemas de irrigação abastecidos com EDP, EDS e EDT.

This work aimed to evaluate the influence of daily supplementation with 10 g of polyethyleneglycol (PEG) associated with Sabiá shrub hay (Mimosa caesalpiniifolia Benth.) on the intake and digestibility of in goats and sheep. Twenty animals, ten sheep and ten goats were allocated in a randomized block design, with two treatments and two species: PEG group (supplemented with 10 g of PEG) and control group (without supplementation). Significant differences were not observed between treatments and species regarding the intake and digestibility of dry matter and neutral detergent fiber. Nevertheless, PEG supplementation enhanced the crude protein digestibility of Sabiá shrub hay from 33.96% to 38.74% in sheep and from 43.29% to 54.41% in goats, showing that the supplementation with PEG could become a good feeding strategy against the antinutritional effects of tannin of the forage plants.

The objective of this research was to evaluate the wood natural resistance of Mimosa caesalpiniifolia Benth. of phenotypes (plants) with and without prickles to subterranean termite (Nasutitermes corniger Motsch.) in forced feeding and feeding preference assays, under laboratory conditions. Wood test samples measuring 2.54 x 1.50 x 0.64 cm (forced feeding) and 10.00 x 1.50 x 0.64 cm (feeding preference), with the largest measurement in the fiber direction, were obtained from three positions from pith to bark direction. The samples were exposed for 28 days (forced feeding) and 45 days (feeding preference) to Nasutitermes corniger Motsch. termites. In forced feeding assay the termites caused superficial attack in wood and lived during 8 to 10 days, thus the wood was classified as resistant. In forced feeding assay more mass loss and attack in wood of external positions to both phenotypes was observed. To the waste and survival time of termites were similar to both types. In feeding preference a larger mass loss and waste to inner position in both phenotypes was observed. In general, the plants with prickles lost more mass than the one without prickles. Therefore, the wood of plants without prickles is more suitable to be use in construction of fences, sheepfolds and other similar uses where the wood shall be subject to attack by termites.
