Nutrição mineral e qualidade do fruto do abacaxizeiro e do maracujazeiro

Several factors influence the productivity and fruit quality of pineapple and passion fruit, among which are: climate, soil fertilization and irrigation practices. Mineral nutrition is essential to increase productivity and improve fruit quality; however, there is a few information about the effect of fertilization in these two fruit crops, especially under tropical conditions. The objective of this review was to compile the main research results, in which the influence of mineral nutrition on the fruit quality was evaluated. We considered the information recently published in scientific journals, and presented it for the macronutrients individually, then to NPK and, finally, the micronutrients. The review showed that it is difficult to say that some element favors or not certain characteristics of pineapple and passion fruit fruits, since the results are inconsistent and there is not many information. More than established the effects of mineral nutrients on the fruit quality of these two fruit crops, we stand out that research in this topic is very necessary.

Determinação da matéria seca e teores de macronutrientes em folhas de frutíferas usando diferentes métodos de secagem

O objetivo desse estudo foi avaliar diferentes métodos de secagem de folhas para três diferentes frutíferas (maracujá, pêssego e abacate), com relação à determinação da matéria seca e os teores foliares de macronutrientes. Foram coletadas amostras de folhas recém expandida de três culturas, do pomar da fazenda de ensino e pesquisa da FCAV-UNESP, câmpus de Jaboticabal, no mês de janeiro de 2010, coletando-se para cada cultura 12 amostras com 25 folhas cada. Os tratamentos constituíram-se por dois métodos de secagem, estufa de circulação de ar forçada regulada a uma temperatura de 70°C e o forno microondas (FMO). Avaliou-se a massa da matéria seca e os teores foliares de macronutrientes. Os resultados sugerem que os dois métodos de secagem testados se assemelham na determinação de matéria seca e nos teores foliares de macronutrientes para as culturas análisadas, exceto os teores de cálcio na cultura do pêssego.

Manejo cultural do maracujazeiro-amarelo em ciclo anual visando à convivência com o vírus do endurecimento dos frutos: um estudo de caso

Este estudo de caso teve por objetivo analisar a qualidade dos frutos e a produtividade em t/ha de maracujá-amarelo, em dois ciclos anuais, plantados, respectivamente, nos dias 04-10-04 (1º plantio) e 20-08-05 (2º plantio). As mudas da seleção Afruvec foram formadas em tubetes no interior de estufa com tela antiafídeo. O pomar, nos dois ciclos produtivos, foi irrigado por gotejamento, adotando-se uma densidade de 1.600 plantas/ha. O 1º plantio foi erradicado no dia 13-07-05, em função de o pomar apresentar a totalidade das plantas com sintomas típicos do vírus do endurecimento dos frutos (PWV) nas folhas e frutos. No 1º e no 2º plantios, os sintomas tiveram início no dia 26-01-05 e no dia 04-01-06, respectivamente. Não houve necessidade de eliminação de plantas em ambos os plantios, já que o início dos sintomas de PWV ocorreu quando as plantas se encontravam em pleno florescimento. Pelos resultados, pode-se concluir que o manejo adotado regionalmente, com plantio em ciclo anual, permitiu uma ampliação do período de colheita, decorrente da antecipação de plantio no 2º ano; uma produtividade de 16,94 kg/planta e 18,39 kg/planta, no 1º e 2º anos, respectivamente; um aumento da rentabilidade na safra de 2006 em função: da maior produção, melhor cotação dos frutos para mesa e indústria, e aproveitamento dos investimentos realizados no 1º ano. As técnicas empregadas promoveram uma eficiente redução do potencial de inóculo regional, favorecendo uma sustentabilidade na produção.

O rúgbi e seus valores educacionais na escola

Physical education in their school environment can contribute positively in the training of students as it is in this discipline that many students feel more motivated to discuss and reflect on conflicts related to school life or in society. In this study we treat the rugby exploring attitudes and values that are present in this sport, considered important for the development of the student, with the methodological approach the dimensions of the contents developed by Coll et al. (2000) and Zabala (1998). Thus, the aim of this study was to develop rugby content emphasizing the values linked to it with students of the 5th year of primary education in a public school in the city of Rio Claro / SP. Among the values are integrity, passion, solidarity, discipline and respect that will be developed through conceptual and procedural lessons about rugby and its educational values, also taking advantage of situations up to during classes for discussions. The survey was conducted for 3 months. The evaluation was by holding a tournament organized by the students and by the researcher to observe what they learned regarding the dimensions of rugby contents (conceptual, Procedural and Attitudinal) and an essay where students expressed the experiences. As a result we see the importance of working educational values in society and the implementation of educational sports at school as a motivational tool. With the contribution of this research, it is expected that rugby can be worked in schools as an educational sport for the training of the individual and the development of physical culture of the students

Reação de maracujazeiro amarelo a Meloidogyne Incognita Raça 3

This study concerned the reaction of yellow passion fruit ‘Maguary’ and ‘Afruvec’ to the phytonematode Meloidogyne incognita race 3 in greenhouse conditions. An entirely randomized experimental design with 3 treatments (‘Maguary’, ‘Afruvec’, and tomato cv. ‘Rutgers’) and 4 repetitions was used, each plot consisting of 1 vase containing 1 plant. After 6 months, an evaluation was made of the index of galls and egg mass in the yellow passion fruit varieties and in the tomato cv. ‘Rutgers’. The classification of resistance to the phytonematode was made by criterion of the reproduction factor (RF). ‘Maguary’ presented a zero index of galls and egg mass, while ‘Afruvec’ showed a low index of galls and egg mass in relation to the tomato cv. Rutgers. According to the RF, ‘Maguary’ was characterized as immune to the phytonematode, while ‘Afruvec’ was resistant, and the tomato cv. ‘Rutgers’ was susceptible.

Germinação de sementes de maracujazeiros: água, luz, temperatura e reguladores vegetais

The production of seedlings of passion fruit is done mainly with the use of seeds by most producers. It can also be propagated by cuttings, layering and in vitro tissue culture. However, even when grafting is used, it is necessary to use seeds to produce the rootstock. Nevertheless, most Passifloracea species have germination problems, making it difficult to obtain seedlings. Although several studies have been developed in an attempt to increase seed germination of passion fruit there are still difficulties in understanding the germination process and also disagreement about seed dormancy. Thus, the present study aimed to review papers related to seed germination of passion fruit emphasizing aspects such as mechanical resistance to water ingress, the need for adequate light and temperature and the use of plant growth regulators in overcoming seed dormancy. It was noticed that, in general, the passion fruit seeds are photoblastic negative and exhibit physiological dormancy, being no need of seed scarification to stimulate its germination.

A enxertia na cultura do maracujazeiro: aspectos anatômicos, bioquímicos e fisiológicos

Due to the expansion of orchards, problems with soil pathogens are frequent and cause injury and/or make passion fruit cultivation impossible in Brazil. Thus, studies with potential species for rootstocks become indispensable to assist in the technological development of the culture. It is necessary to take into account several aspects of grafting, for the adoption of appropriate techniques, among them we can highlight the anatomy, physiology and also biochemistry. This study aimed to review the existing papers related to grafting of passion fruit and also to understand the operation of grafting itself. It was observed that several publications are related to the topic of the present review and that grafting is a viable alternative to the cultivation of passion fruit, however additional studies about grafting and production are needed.

Coeficiente de cultivo e lâminas de irrigação do maracujazeiro amarelo nas condições semiáridas

The study aimed to determine the coefficient of the yellow passion fruit cultivation and irrigation set capable of increasing crop productivity and quality of production in the environmental conditions of the semi-arid region of Piauí. The experiment was conducted in the Pilot Project for Fruit Crops Irrigated area in Santa Rosa, PI. We used a randomized block design with six treatments and four replications. Treatments (irrigation) were defined according to percentages of reference evapotranspiration (ETo): T1 25%, T2: 50%, T3: 75%, T4: 100%; T5: T6 and 125%: 150%. For monitoring water in the soil profile was used tensiometers. To determine the crop coefficient (Kc) used the water balance in the soil treatment based on 100% replacement of water. Morphological and physiological characteristics of yellow passion fruit were evaluated. The maximum yield of 27.052 kg ha-1 yr-1 was obtained by applying a water depth of 763.80 mm. The values of average fruit weight ranged from 0.207 kg (T6) and 0.159 kg (T1). The average kc obtained for the vegetative stage was 0.57 to 0.94 and flowering stage to fruiting phase 1.04. The water depth of greater efficiency comprise in the range of 75% and 100% ETo.
