The guajava is principally cultivated in tropical and sub-tropical regions. The Brazil is one of the principal producers worldwide besides with India, Paquistan, Mexico and Venezuela. The fruit can be used in the industrialization generating many subproducts. The objective of this paper was to evaluate the efficiency of resistance inducers alone and associated with hydrothermal treatment in the control of anthracnose of guajava. The fruits that were treated with Agro-Mos® presented minor severity in comparison to the others treatments (Crop-Set, Methyl Jasmonate and Chitosan). The Agro-Mos® was selected to be used associated with the hydrothermal treatment. The temperatures treatments, 47ºC, in any time of exposure and 50ºC in the time exposure of 3 and 6 minutes differs significantly to the others, independently of the association with the inductor.

The objective of this work, is to evaluate the growth components of castor cultivars under irrigation conditions in the region of Mossoró, Rio Grande do Norte State, Brazil. For both, used to the design in blocks randomized, and the treatments consisting of castor cultivars CSRN-142, CSRN-393, CSRD-2, CNPAM-2001-49, CNPAM-2001-50-2001-and CNPAM 212) and times of assessment (to 29, 40, 50, 64 and 78 days after planting - DAP), arranged in the scheme split plots 6 x 5, with six repetitions. The growth was measured by plant height (HP), the stem circumference (CIRC) and leaves number per plant (NL). Cultivars differ among themselves about the growth characteristics in all seasons studied, except for the first timemaking data for HP and NL. The CNPAM-2001-49 and CNPAM-2001-50 showed, in general, very similar behavior, and cycles with size larger than the CSRN-142, CSRN-393, CSRD-2.

The objective of this work, the performance of three varieties of soybean on "Tabuleiros Costeiros" State of Alagoas. The installation of the experiment occurred on March 20, 2006, picking up the parcels on 26 August 2006. The experimental design was a randomized blocks with seven repetitions. The experimental plots consisted of ten rows of 4.0 m in length, spaced 0.50 m. In ten plants per plot were marked certain height of the plant in full bloom stage R2 and point of harvest stage R9 considering the distance between the soil surface and apical end of the main stem, the body weight of 100 seeds, grain production and dry weight in (kg ha-1) which are calculated from the production harvested per plot. The soybean plants of three varieties showed height below the minimum required for mechanical harvesting. The three varieties yield or more of the traditionally producing. The average of dry matter accumulation obtained show the variety BRS Tracajá as a good option for the production of forage.

The objective of this work was to evaluate the postharvest quality of the Tommy Atkins mango commercialized in the city of Mossoró-RN. The fruits had been collected, randomized, in three commercial establishments (Market of great port, free Fair and market of small port). In each establishment 6 collections had been carried through, distributed during the months of August, September and October. The experimental design was blocks randomized with three treatments and six repetitions, two fruits for experimental unit for physicist-chemistries analyses and five fruits for phytopathology analyses. The days of collection had been considered as blocks and the markets as treatments. The variables analyzed were: mass, longitudinal and ventral lengths, price, internal appearance, external appearance, firmness, solubles solids, titratable acidity, solubles solids and titratable acidity relation, pH, incidence and frequency of fungus isolation. The fruits commercialized in the three establishments had presented physical and chemical characteristics that fit in the standard considered reasonable for consumption in natura of 'Tommy Atkins' fruits. It was found high incidence of spots and/or podrition, mainly in market C. The fungus found in the isolation frequency had been of the Colletotrichum, Alternaria, Aspergillus, Lasiodiplodia and Rhizopus.

Jatropha curcas crop is raising attention as an alternative crop for oil and biodiesel production. Despite the mineral fertilization is an important factor for increasing Jatropha curcas yield, few research has been made on this issue, mainly on the use de zinc and copper. In order to evaluate the effects of these elements on Jatropha curcas plant growth two experiments were carried out in a greenhouse, in Campina Grande, Paraiba State, Brazil, from July to December 2007. The substrate for the pot plants was a 5 mm-sieved surface soil (Neossolo Quartzarênico). The experimental design was a completely randomized with three replications. The treatments of first and second experiment were composed of five levels of Zn (0; 2; 4; 6 and 8 mg dm-3) and five levels of Cu (0; 1; 2; 3; and 4 mg dm-3) which were applied at the time of planting. One plant of Jatropha curcas was grown per pot after thinning and was irrigated whenever necessary. Data on plant height, number and length of leaves and stem diameter were measured at 40; 60; 80; 100 and 160 days after planting. Under conditions that the experiments were carried out the Zn and Cu levels used did not affect the Jatropha curcas plants growth.

The desertification generates and accents the scarcity of vital natural resources for the survival human being, as drinking waters, alone agriculturist and vegetation. Implying in social and economic problems in the affected areas. Recently the remote sensing and the techniques of geoprocessing has been used in diverse areas of the research, mainly in the ambient monitoring of Brazil. For its great territorial extension the application of these tools is of great importance in the country, has seen that if it can thus carry through diagnostic of areas of difficult access by means of transports and in accordance with the secular resolution of the effective satellites can be carried through a monitoring of these areas. The present study it has as objective to analyze the evolution of the process of desertification through the NDVI in the region of the Hinterland of the State of Pernambuco through a secular series of images Landsat Thematic Mapper (TM) that it includes years 1994, 1997 and 2001. It was applied the Surface Energy Balance Algorithm for Land - SEBAL, this algorithm calculated the albedo and the Normalized Difference Vegetation Index for each pixel of the images. It was verified that the characteristic vegetation of the region diminished its area, showing that the analyzed areas meet in process of loss of the vegetation that can lead to the desertification process.

It was objectified, in this work the standardization of the germination test with relationship to the temperature and the removal of the tegument for the evaluation of the seeds of pinhão-manso (Jatropha curcas L). For so much, the germination test was accomplished with four repetitions of 25 seeds for each treatment. The treatments was arranged in a complete randomized design, in outline factorial 4 x 2 (4 temperatures 20 ºC; 25 ºC; 20-30 ºC and 30 ºC, and 2 type seeds with and without tegument). The sown was accomplished in system roll, humidified with volumes of water (mL), equivalent to 2.5 times the weight of the paper (g). The treatments were installed in cameras of germination of the type BOD under regime of white light. They were appraised the germination with counts to the 10 and 15 days of the beginning of the test and index of germination speed. In agreement with the results obtained in the present work, it can be concluded that the seeds with tegument presented larger germination percentage, and the retreat of the tegument affects the germination and vigor of the seeds negatively. The temperatures of 25 ºC and 30 ºC constants are favorable the germination and vigor of the seeds, while the temperatures of 20 ºC constant and 20-30 ºC alternate they commit the acting in the germination and vigor of the seeds of pinhão-manso.

A survey was made of the plant species used in popular medicine in the coastal city of Natal, and the rural city of Santa Cruz, both in the northeastern Brazilian state of Rio Grande do Norte. Information on the medicinal properties of the plants was obtained from interviews with local residents performed between February and August, 2005 and between September and December, 2007. In each area, 100 inhabitants filled out standard forms, for a total of 300 interviews. Data was collected on the plant (popular name, part of the plant used, form of use and function) and on the population (age group, sex and schooling). We recorded 57 species distributed into 54 genuses and 34 botanical families. Regardless of schooling level, more than 50% of the respondents reported using plant species for curing a wide assortment of ailments. The most used families in terms of number of species were: Lamiaceae (seven), Euphorbiaceae (four), Myrtaceae (four), Zingiberaceae (three) and Lauraceae (three). Around 49% of the species were common to the three areas studied. The most used plant parts for preparing remedies, which are used mainly for treating respiratory diseases, were the leaves, fruits and roots. Teas are the most common form of dispensing the medicine. A table is presented containing information, especially on the use and function of the species, as described in the interviews.

Erythrina velutina Willd. is a Fabaceae, popularly known as mulungu. Of the several species spread around the world about twelve are found in Brazil. Mainly in the Brazilian northeast the bark is used due to its sudorific, sedative and topical anesthetic properties. The presence of fungi in seed germination can reduce, causing the death of seedlings or transmit diseases to adult plants. The work has as objetive to test the thermotherapy and chemical treatment in the control of fungi associated with the mulungu seeds of three districts in the state of Paraiba. The sanity was carried by "Blotter test" and physiological quality of seeds was evaluated by germination, first germination counting and drymass. The heat treatment used was hot water at 60°C for 5, 10 and 20 minutes. The chemical treatment was done with the fungicide Captan® TS. It was used by treatment 100 seeds, which were incubated forseven days, the temperature of 22 ± 2 ° C and photoperiod of 12 hours. The qualitative and quantitative evaluate of the fungi associated with seed was done with the help of stereomicroscope and expressed as a percentage. In the samples examined, it was the incidence of fungi Aspergillus niger, Aspergillus flavus, Aspergillus sp., Penicillium spp., Cladosporium sp., Rhizopus sp., Fusarium sp and Botritis sp. The results show that the heat and chemical treatments reduced significantly the germination and first count of the locations studied.
