The objective of this work was to evaluate the effect of the urban waste compost on the yield and heavy metals concentrations in red beet plants (Beta vulgaris L.) in soils with different textures. The experiment was carried out in greenhouse in polyethylene recipients of 9 dm3. The experimental treatments resulted from a 3 x 4 factorial arrangement of a Red Yellow Latosol, sandy clay loam, (LVAfaa), a Red Yellow Latosol, loamy sand, (LVAfa) and a Quartzarenic Neosol, sand loam, (RQ), combined with the urban waste compost doses of 0, 30, 60 and 90 t/ha, in dry base. The experimental design was in randomized blocks with three replications of the treatments. Soil pH, fresh and dry matter weight and Zn, Cu, Cd, Pb and Ni concentrations in the soil and the leaf tissue were determined. Amongst heavy metals determined, Zn and Cu had been only influenced by the soil texture, being biggest concentrations in the soil with bigger amount of clay. The dry and fresh weights of the red beet root had increased with the increment of the doses of compost, having reached maximum values, inside of the experimental interval, with the 90 t.ha-1. Otherwise, the heavy metal content in red beet root decreased with the increase of the doses of compost. As much the Ni how much the Pb had presented content level in root above of the allowed maximum limits for the consumption, as values established for the Brazilian legislation.

The work was conducted in Acauã site, in Caucaia - Ceará State, in a "semi-árida" coast region. The objective was to evaluate thermal stress occurrence and his possible impact on ovulation induction treatment efficiency, onset of estrous behavior of dairy Goats from different breeds. Twenty two adult goats were utilized: 10 Saanen, 4 American Alpines and 8 ½ Murciana x undefined breed, raised in installations with high floor, side windows and sunny areas. The estrous induction treatment was conducted using vaginal sponges with MAP, intramuscularly Cloprostenol and eCG. In the environment were registered air temperature and humidity, Radiant Heat Load and Black-Globe Humidity Index. Rectal temperature was similar between breeds and partum order. Respiratory rate was higher in Alpine goats. The induction treatment and estrous behavior interval was similar in ½ Murciana x undefined breed goats and Saanen goats and higher in Alpines and multiparous goats. The fertility rate at 1st AI was lower in ½ Murciana x undefined breed goats and multiparous goats.

The rational exploration of Tayassu tajacu, popularly known as collared peccaries, may well contribute toward diminishing the predatory hunt for this animal. The object of the present study was to evaluate the effect of sex and castration in relation to amounts of cholesterol and fatty acids found in the meat of animals raised in a captivity. A total of 12 animals was used, 8 being male (of which 4 had been castrated) and 4 female. All of the animals were given the same type of treatment and the same food. After the animals had been slaughtered, the frozen carcasses were carefully packed and sent to the laboratory responsible for examination of meats and fish which is part of the Department of Nutritional Technology of the Federal University of Ceará, in order to determine the quantity of cholesterol and fatty acids present in the meat of these animals. The amount of cholesterol in the meat of the females was less than that found in the meat of the non-castrated males. In relation to the quantity of fatty acids, the meat of the female species presented a smaller percentage of linoleic and arachid acids and a higher percentage of palmitic and palmitoleic acids when compared to both the castrated and non-castrated males. Castration appears to have had no effect on the amount of cholesterol in the meat of the male species, whichpresented an acceptable lipoid profile due to the presence of considerable quantities of linoleic acid and a lower percentage of cholesterol than that found in other domestic or wild species .

Due the necessity to look for alternatives to produce larger amount of quality foods, as well as to develop research that seeks viable solutions for use of waters of the low quality, this work was addressed. The objective was to know the behavior of red earthworm of California when watered with waters of different from salinity for 45 days. The experiment was installed in the earthworm house of UFERSA. The design used was randomized blocks with four treatments and six repetitions. The used treatments were watering waters with four levels of electric conductivities (T1 = 0.5 dS m-1 T2 = 5.0 dS m-1 T3 = 10.0 dS m-1 T4 = 15.0 dS m-1, being T1 originating from local well and the others obtained by the increment of chloride of sodium (NaCl) to the water used in T1. The 24 portions were composed by concrete pitchers containing 1.5 liters of tanned manure and 6 young earthworms of uniform size. The Mass of Head offices Final Average and the Relative Mass of Head offices they didn't suffer significant decrease when the salinity of the watering water increased from 0.5 to 5.0 dS m-1. The watering of earthworms with waters of electric conductivity of up to 5.0 dS m-1 didn't cause any mortality of head offices. The reduction of the Mass of the Final Population went of 1.69 g to each dS m-1 increased in the electric conductivity of the watering water. The Relative Population Growth of earthworms decreased 6,6 times when the electric conductivity of the water increased from 0,5 to 5,0 dS m-1.

A phytosociological comparative study was performed in two "caatinga" areas (A - productive pasture and B - degraded pasture), in the eastern "Cariri" microregion of Paraíba State, Northeast of Brazil. The multiple plots method was used, where 40 plots were established in each area, being measured living trees and shrubs with diameter at base height (DAB) ³ 3 cm and plant height (At) ³ 1 m. Eight botanic families, ten genera, and ten species were identified in area A. The Cactaceae and Mimosaceae were the best-represented families in number of individuals in this area. Six families, eight genera, and nine species were identified in area B, where Cactaceae, Mimosaceae and Euphorbiaceae were the best-represented families. The following parameters, total number of sampled individuals (N), basal area (BA), and total density (TD) had in area A 438 individuals, 12.22 m2.ha-1, and 2737 individuals per hectare, respectively, which were higher than area in B, that had the following values: 308 individuals, 11.31 m2.ha-1 e 1925 individuals per hectare, respectively. These results allow to postulate that the uncontrolled grazing practiced in that microregion of Paraíba State, is leading to an environmental degradation of the "caatinga" phytocenosis (a set of plants with ecological similar preferences, living in the same biotope).

The use of water of inadequate quality is pointed out as one of the causes of failure inseedling production. Absence of indication of salinity tolerance for West Indian Cherry (Malpighia emaginata D.C), an experiment was carried out in randomized block design, with the objective of studying the effects of 6 level of eletrical conductivity of irrigation water (ECw) varying from 0.5 to 5.5 dS m-1 on the formation of seedlings of West Indian Cherry utilizing clone BV1 as rootstock and clone BV7 as graft. The irrigation water of desired ECw was prepared maintaning equivalente proportion of 7:2:1, among Na:Ca:Mg, respectively. The water growth of rootstock was evaluated at 50 days after application of treatments and of grafted seedlings at 15 and 50 days after grafting. The water with ECw of 5.5 dS m-1 does not affect the adequability of rootstock for grafting neither the sprouting of graft at the time of transplanting.

The influence of seed position and sowing depth on seedling emergence and growth in Moringa oleifera Lam. in two laboratory experiments at Universidade Federal Rural do Semi-Árido, UFERSA, RN, Brasil. In one experiment, the influence of three sowing depths (2.0, 3.0 and 4.0 cm) were evaluated through percent of emergence, emergence velocity index (EVI), seedling height, and whole seedling dry matter. In the second, it was studied the influence of seed position (apex upward, lateral and apex down) on percent of emergence, EVI, seedling height, root length, and whole seedling fresh and dry matters. Both experiments were completely randomized with four replications of 50 seeds. Sowing at 2.0 cm deep provided higher percent of emergence, IVE and seedling height. Seed position did not affect percent of emergence and seedling dry matter, height and root length, however, when the seeds were sown with the apex upward or lying, seedlings had greater fresh matter and higher EVI.

Mimosa caesalpiniaefolia Benth., (Mimosaceae) it´s a Northeast native species from Brazil and cause its multiple utilities, it has been intensively used. Is conventionally propagated through seeds, but this process isn't easy and plant with a wide range of genetic variability. For this reason, the micropropagation assumes importance. Two experiments had been lead, being that in the first, different combination of 2,4-dichlorophenoxyacetic acid (2,4-D) and benzilaminopurine (BAP) were evaluated and in the second, two ways of culture. In the first experiment the explants had been gotter from three years old plants and inoculated with MS medium (Murashige & Skoog, 1962) substance in different concentrations of 2,4-D and BAP. The observed variables were number of shoots for explants, number sprouted explants and percentile of contamination. In the second experiment explants from sprouted in vitro plantlets inoculated with a complementary formularization substances called MC1 (25 mL of medium with next composition: 20% water coconut (v/v), myo-inositol (0,1 g.L-1), ascorbic acid (0,09g.L-1)) and MC2 (20% water coconut (v/v), myo-inositol (0,1 g.L-1), ascorbic acid (0,1 g.L-1), (0,0155 g.L-1), tiamin (0,02 g.L-1), boron (0,0015 g.L-1), extract of malt (0,3 g.L-1)), both solidificed with agar (7g.L-1). In these experiments the observed variables were number of shoots per treatment and number of callus per treatment. In the combination of 2,4-D and BAP, none morphogenetic reply in the inoculeted tissues was identified. The substances MC1 and MC2 had induced in average callus sprouted in 85,8% of the inoculeted explants. In the first experiment, 34% were infested by fungus.

The aroeira (Myracroduon urundeuva Fr All) is a Anacardiaceae of natural occurrence since the Caatinga ties Argentina and Paraguay, being found in vegetal formations of caatinga, closed and forests pluvial. The species and to cultivate if hold of different form to the salinity, that is, each species of plant or to cultivate tolerates until certain salinity (Salinity threshold - SL), without reducing its potential income. This work had the objective to evaluate the germination if seeds of aroeira in different levels of salinity. One used different Chloride concentrations of sodium and calcium Chloride in the following amounts: 6,4g. 12,8g, 19,2g. The salinity intervened with all the parameters evaluated in the test of germination of the aroeira, to the measure that increased - the concentration of you leave yourself, had decrease in the analyzed 0 variable, being that, from 19,2g the germination of this culture sufficiently is harmed.

This work was based on dried specimens, including types, field works (collects and observations) mainly in Brazilian Northeastern, as well as information obtained in the specialized literature. Eleven genera, and approximately 150 species, belonging to four subfamilies were recorded: Boraginoideae, Cordioideae, Ehretioideae and Heliotropioideae. An illustrated key to the recognition of the genera of Boraginaceae native from Brazil based on its floral and fruit features are presented.
