Leonardo Assis Dutra, Fabianno Cavalcante de Carvalho, Eneas Reis Leite, Magno José Duarte Candido, Jo?o Ambrósio de Araújo Filho
American Journal of Plant Sciences (AJPS) , 2014, DOI: 10.4236/ajps.2014.55077
Abstract:

This work aimed to evaluate the effects of different individual heights of cut on structural characteristics of Brachiaria hibrida cv. Mulato I in four periods of the year. The study was carried out at the Fazenda Experimental Vale do Acaraú, in Sobral, Ceará, Brazil, from January to December, 2008. The experimental design was a split plot, with the plots representing four pasture conditions through manual cuts of 10 cm, 20 cm, 30 cm and 40 cm heights, which were done every 30 days. Each treatment had three replications. The subplots were represented by four periods of evaluation: January-February-March, April-May-June, July-August-September and October-November-December. Fertilization was performed with 350 kg of N/ha, divided into monthly applications. Irrigation was conducted in alternate days during the dry season. The variables studied were: mean height before cutting (cm); dry matter content (%); total dry matter production (t/ha); percentage of leaves; percentage of stems; percentage of dead material; leaf blade/stem ratios; number of total leaves per tiller; number of live leaves per tiller; average size of leaves; and tiller density. Cutting at 10 cm caused a decrease in total dry matter production, underestimating the potential production. Cutting heights between 20 and 30 cm contributed positively to increase the total number of leaves, number of green leaves, average size of the leafs and total dry matter production. Under the present experimental conditions, cutting around 40 cm was not recommended because of a decreasing in the leaf/stem ratio and a increasing in stem fraction and dry matter content, compromising the structure of the canopy.

American Journal of Plant Sciences (AJPS) , 2015, DOI: 10.4236/ajps.2015.614234
Abstract: Transgene insert location in the genome through different methods is random. Thus, alterations in the expression of desired trait may occur, as well as alterations in the expression of other characteristics of receptor plant. The purpose of this study was to compare Bt transgenic maize hybrids and the respective conventional isogenic hybrid in relation to adaptability and phenotypic stability. Field trails were set up in four locations of Minas Gerais, Brazil (Campo do Meio, Lavras, Madre de Deus and Paragua?u). A randomized complete block design was used, with three replications, and the treatment structure was a factorial 6 × 2, with six hybrids in the transgenic and conventional versions. Plant and ear height and grain yield were evaluated. To estimate stability, the Anicchiarico, Wricke and AMMI methodologies were used. Grain yield and ear height of the transgenic hybrids and their respective conventional isogenic hybrid did not differ. There are differences in the phenotypic stability between transgenic hybrids with Bt technology and their counterpart conventional isogenic hybrid.

Caracteriza??o fenotípica e molecular de esporos de fungos micorrízicos arbusculares mantidos em banco de germoplasma
Novais, Candido Barreto de;Souza, Francisco Adriano de;Siqueira, José Oswaldo;
Pesquisa Agropecuária Brasileira , 2010, DOI: 10.1590/S0100-204X2010000800015
Abstract: the objective of this work was to characterize phenotypically and genotypically isolates of arbuscular mycorrhizal fungi (amf) maintained in pure culture and to evaluate the applicability of pcr-dgge analysis, developed for gigaspora, for molecular identification of amf species belonging to other genres. the species phenotypic characterization was done according to morphological criteria, as described by taxonomy, and according to original descriptions of species published in the specialized literature. the genotypic analysis was made through specific discrimination of the v9 region in the 18s rdna, which allowed the distinction of species and showed no difference among geographical isolates of glomus clarum, and among those of glomus etunicatum. this indicates the applicability of this technique for assessment of genetic purity and discrimination of amf species.

Abstract: 124 small mammals around the americana reservoir (=salto grande reservoir) were trapped during the period january, 1972 to august, 1975, in places where human and snail (biomphalaria tenagophila) infections by s. mansoni have been recorded. the mammals included: 44 specimens of cavia aperea aperea, 9 didelphis albiventris, 7 holochilus brasiliensis leucogaster, 39 lutreolina crassicaudata, 3 mus musculus brevirostris, 14 oryzomys nigripes eliurus, 1 oryzomys subflavus, 4 rattus rattus and 3 zygodontomys brachyurus. two d. albiventris, 3 h. b. leucogaster and 5 l. crassicaudata were found naturally infected with s. mansoni. the presence of eggs was verified in feces and intestines and the worm burden was determined through recovery of schistosomes from mesenteric vessels and the hepatic portal system. the mature eggs of s. mansoni were rarely found in the feces of l. crassicaudata and d. albiventris although they were common in h. b. leucogaster. the low abundance of h. b. leucogaster in the study area probably indicates that this rodent contributes little to the dissemination of s. mansoni eggs. it does not appear that the small mammals in this region have an important role in maintaining the s. mansoni life cycle.

Abstract: The intention major duty of a conception of interdisciplinary thinking in the light of which is proposed by some of contemporary epistemologies and having education as a continuous process, can not distance themselves from reality concrete learner and educator, seeking consistency between saying and doing, between thinking and acting, between feeling and talking. Thus, this article aims to analyze the perceptions of students of an interdisciplinary Graduate Program in Natural Resources, Federal University of Campina Grande, in 2010. We used the exploratory research with quantitative and qualitative through semi-survey questionnaire structured. The deductive method was used. It was made using the techniques of descriptive statistics and factor analysis. The results found by Factor Analysis (FA) point to four factors relevant to the perception interdisciplinary study of the students, the first named Prospects for an Interdisciplinary practice - the largest total variance explained by the factor - 28.33%, the second by the Interdisciplinary Student Interest - 15.020%, followed by the third related to the Strategies or Interdisciplinarity in Environmental Graduate - 13.71% and finally the fourth Relevance of Focus and Lack of Integration of Disciplines Program – total variance 13.39%. It was felt that the challenges for the insertion of interdisciplinary programs in the Graduate Area Resources Natural can be overcome to the extent that this question, in fact, will be treated with greater consistency at the collegiate, teachers and students of way that can effectively reflect the needs that the environmental area need.
