Abstract: O objetivo deste trabalho foi avaliar os efeitos do estresse hídrico no estabelecimento, desenvolvimento e na taxa de sobrevivência de 11 linhagens de sorgo forrageiro em casa de vegeta o. O delineamento experimental foi o de blocos ao acaso no arranjo de parcelas subdivididas no tempo, com cinco repeti es. As unidades experimentais foram constituídas por recipientes de 250 L, onde foram colocados 187,9 kg de solo da classe textural areia franca. O estudo compreendeu dois períodos de estresse, e três irriga es, sendo uma no início e as outras aplicadas quando grande número de folhas tinham aspecto de palha seca. No primeiro período, as linhagens apresentaram alta taxa de sobrevivência, demonstrando resistência ao estresse hídrico. As linhagens que apresentaram menor velocidade de crescimento nesse período sofreram menos com o estresse. No segundo período n o ocorreram diferen as significativas entre as linhagens com rela o ao desenvolvimento das plantas. Durante os dois períodos de estresse, a velocidade de crescimento n o diferenciou satisfatoriamente linhagens de comportamento distintos, quanto à resistência à seca, competindo em um mesmo recipiente e em alta densidade populacional. As linhagens 84, 29, 99, 41, 63 e 104 apresentaram maior resistência ao estresse hídrico e as linhagens 33, 38, 40, 67 e 92, menor resistência.

Abstract: the objective of this work was to determine the coefficients of repeatability of morphophysiological traits in elephant grass (pennisetum spp.) genotypes, from data obtained during six evaluation cycles. the minimum number of measurements and genetic parameters were estimated. the experiment design was a randomized complete block, in a split?plot arrangement, with four n levels (control, 30, 60, and 90 kg ha?1 per cut) and 16 pennisetum genotypes (11 interspecific hybrids and five cultivars). the cycles consisted of evaluations in 2010 (4/21, 7/19, and 9/28) and 2011 (1/6, 4/7, and 8/3). the coefficients of repeatability were of medium?high magnitude for all variables, indicating that there was regularity between repeated measures. for the variables forage mass, plant height, leaf length and width, stem diameter, leaf chlorosis and area index, three cycles of evaluation are enough to reach r2 of 90% by principal component analysis. for internode length, the minimal of seven evaluations is necessary to predict the true value of genotypes. the genetic parameters of the variables forage mass, leaf length and width, stem diameter and leaf chlorosis are of high magnitude, favoring the selection of superior pennisetum genotypes.

Abstract: the objective of this work was to evaluate the effects of water deficit stress on establishment, development and survival rate of 11 forage sorghum lines in a greenhouse. the experiment was carried out under a randomized block design, with split-splot arrangement and five replications. each replication was formed by a container of 250 l capacity, filled with 187.9 kg of sandy soil. two stress periods were studied, with three irrigations, at the begining of tests and when the plants showed large numbers of dry leaves. during the first period all lines had high survival rates showing resistance to water deficit stress. slower growing lines suffered less with the imposed water deficit. during the second water deficit stress period there were no significant differences between the lines in plant development. along both stress periods, growth rate did not distinguish satisfactorily lines with distinct behavior, as relate to drought resistance, when those lines were competing on the same recipient and high population density. lines 84, 29, 99, 41, 63, and 104 had higher stress resistant while lines 33, 38, 40, 67, and 92 had lower stress resistant.

Abstract: the torque curve of an isokinetic evaluation provides indication about muscular performance and possibly deficit in the evaluated subject. however, automatic reports supplied by isokinetic systems may produce equivocated data and interpretations errors. thus, the purpose of this study was to analyze the isokinetic torque curve, identifying at which point of the curve speed becomes constant according to the performed test. moreover, it assesses if the maximum peak torque (mpt) is within the protocol stabilization. swimming athletes (n=10) were evaluated at the isokinetic dynamometer kin-com? 125 ap. the athlete was requested to perform the maximum concentric (cc) - eccentric (ee) contraction in the movements of internal (ir) - external rotation (er), flexion (fl) - extension (ex) and horizontal abduction (ab) - adduction (ad) of shoulder, 120°/sec and supine position. the matlab 6.0 and origin 6.0 software was used to process the curves. in the ir-er movements in cc-ee contractions, considered more stable and with a lower lever arm, the speed remained constant in the range of 5 to 98% of the curves; while in the fl-ex and horizontal ab-ad, considered more unstable and with higher lever arms, 10 to 98% of the curves were observed. the movements of concentric ir and ex and concentric-eccentric fl and horizontal ab-ad, the ptm was concentrated in the first third of the isokinetic curve, which requires attention in the processing of the torque values. in the fl-ee, 80% of the ptm values were outside of the pre-set speed, requiring reprocessing, which would not occur in the reports automatically supplied. we suggest the disposal of the 5% initial and final torque curves for shoulder rotation movements and 10% for fl-ex and horizontal ab-ad in order to obtain more reliable interpretations of peak torque and acquisition of the true muscle condition.

Abstract: Este trabalho foi conduzido com o objetivo de avaliar o efeito do estádio de matura o do sorgo sobre a composi o química da silagem, o consumo, a produ o e o teor de gordura do leite em vacas holandesas, em compara o à silagem de milho. O experimento foi realizado na esta o experimental da Empresa Pernambucana de Pesquisa Agropecuária - IPA, localizada em S o Bento do Una-PE. Foram utilizadas nove vacas holandesas puras, em fase de lacta o, distribuídas em três quadrados latinos. Os quadrados foram formados de acordo com a produ o de leite e a ordem de lacta o e constavam de três vacas e três períodos. Cada período teve dura o de 28 dias. Os tratamentos consistiram de: SM - silagem de milho; SSE - silagem de sorgo fase de emborrachamento; SSL - silagem de sorgo gr o leitoso. Foram ainda fornecidos 25 Kg de palma forrageira animal/dia e concentrado comercial de acordo com a produ o de leite. A silagem de milho propiciou aos animais maior consumo médio de matéria seca da silagem e da dieta total. N o houve efeito significativo do estádio vegetativo do sorgo sobre o consumo de silagem. As produ es de leite total e corrigida para 4% de gordura foram maiores nos animais que consumiram silagem de milho em rela o aos que receberam silagem de sorgo no estádio de gr o leitoso, todavia os que ingeriram silagem de sorgo na fase de emborrachamento n o diferiram dos demais. Quanto ao teor de gordura do leite, n o houve diferen a significativa entre as silagens analisadas.

Abstract: water deficit is one of the major factors limiting the production of sugarcane, especially in areas where there is a prolonged period of water deficiency, such as the west central brazilian region. one way to overcome this problem is to cultivate resistant or tolerant varieties. an experiment was set up at the jalles machado sugar mill, located near goianésia, goiás state, brazil, to evaluate agronomic performance of several sugarcane families. a comparative analysis was carried out among the families under two irrigation regimes, one under regular environmental conditions and another under monthly irrigations during the period of water deficiency. evaluated families consisted of 25 progenies planted in a factorial design with three replications with 20 plants each. the first ratoon crop was evaluated for four yield components, stalk height, stalk diameter, stalk number and brix. by analysis of variance, stalk number and stalk height were influenced by water stress conditions during the initial growth phase, and for stalk diameter and brix, water regime had no effect on the average expression of the characters during the growth phase. the method of classification in four categories proved to be adequate. some families had high values for stalk diameter, stalk number and stalk height under water stress conditions. this study showed that it is possible to select sugarcane families under water deficit conditions associated with higher stalk diameter, stalk number and stalk height.

Abstract: O presente trabalho teve por objetivo avaliar o consumo e comportamento ingestivo de caprinos e ovinos alimentados com palma Gigante (Opuntia ficus-indica Mill) e palma Orelhade-elefante (Opuntia sp.). Foram utilizados 20 animais mesti os, sendo dez caprinos e dez ovinos, alojados em galp o coletivo, contidos individualmente por meio de cordas, distribuídos em delineamento inteiramente casualizado, em um arranjo fatorial 2 x 2 (duas espécies animais e duas variedades de palma). As observa es comportamentais foram realizadas em intervalos de 5 min. por um período de 24h. Os consumos de matéria seca, extrato etéreo, fibra em detergenteácido, carboidratos totais e carboidratos n o-fibrosos foram menores (p < 0,05) quando os animais recebiam palma Orelha-de-elefante. N o houve efeito da variedade de palma, da espécie animal e da intera o espécie animal x variedade de palma (p > 0,05) sobre o tempo gasto comalimenta o e eficiência de alimenta o. O tempo gasto com rumina o foi maior para a dieta com palma Gigante, consequentemente os animais da dieta com palma Orelha-de-elefante permaneceram mais tempo em ócio. Comparando as espécies caprina e ovina, verificou-se que aeficiência de rumina o, tanto de MS quanto de FDN, foi maior para a espécie ovina. Os animais gastaram mais tempo ruminando deitados do que em pé, mas n o foi verificada diferen a quanto ao lado escolhido para deitarem. The objective of this study was to evaluate the intake and ingestive behavior of sheep and goats fed with cactus pear (Opuntia ficus-indica Mill) and prickly pear (Opuntia sp.). Twenty crossbred animals – 10 sheep and 10 goats – were used. They were lodged in a collective shed, contained individually with ropes, distributed using a completely randomized design, and treated with a 2 x 2 factorial arrangement (2 animal species and 2 varieties of cactus). Behavioralobservations were made at five-minute intervals during a 24-hour period. Dry matter, ether extract, acid detergent fiber, total carbohydrate and non-fibrous carbohydrate intake were reduced (p < 0.05) by prickly pear. There was no effect from cactus variety, animal species or animal species x cactus variety interaction (p > 0.05) on feeding time and feeding efficiency. The time spent with rumination was greater for the diet with prickly pear, and the animals on the prickly pear diet remained more time idle. Comparing goats and sheep species, it was verified that the rumination efficiency, for both DM and NDF, was greater for sheep species. The animals spent more time ruminating lying than standing, but no difference

Abstract: The presence of residues of the major groups of pesticides (organohalogen, organophosphorous, pyrethroids and organonitrogen) in representative samples of honey produced in Bauru (state of S o Paulo, Brazil) was investigated from 1999 through2004. A multiresidue method was applied to honey samples to determine 48 pesticides with recoveries ranging from 76 to 95%. The limits of detection found were lower than 10 μg/kg for GC-MS-SIM. The results indicated that most pesticides found in the samples belonged to the organohalogen and organonitrogen groups. Residues of malathion were detected in almost all of the samples in high concentration.
