The study aimed to evaluate energy indicators of a new production system of yellow passion fruit in Marilia-SP. Analyzed the inputs of the biological energy, fossil and industrial and output energy in the form of fruits produced per unit area as well as five energy indicators. The input energy amounted 155,810.13MJ ha(-1). Chemical fertilizers and pesticides accounted for 71% and 24% of indirect energy industry, respectively. The activity generated per cycle / ha, 587.700.00MJ, and cultural productivity 0.19MJ kg(-1). The efficiency culture was 3.77. The cultural energy net totaled 431,889.87MJ ha(-1). The energy efficiency (4.17) and energy balance (550,312.91MJ ha(-1)) was favorable. It was concluded that the direct energy consumption from fossil fuels, even though significant, yet permits the production of the fruit of an environmentally sustainable manner. Chemical fertilizers and pesticides were the most representative of indirect energy industry due to the intensification of fertilization as a means of disease prevention.

A produção de maracujá vem ganhando grande importância no Brasil, notadamente a partir das últimas três décadas, o que coloca o país numa situação de destaque no ranking mundial, sendo o maior produtor do mundo. As principais espécies produzidas e exploradas comercialmente são: Passiflora edulis Sims f. flavicarpa Deg., o maracujá amarelo ou azedo e Passiflora alata Dryand, o maracujá doce. Apesar de serem espécies bem difundidas, há poucos estudos que as relacionem. Desta forma, o presente trabalho objetivou comparar as polpas das duas espécies, avaliando suas semelhanças e diferenças através de testes físico-químicos e determinando seus compostos bioativos. O estudo foi conduzido no Laboratório de Controle de Qualidade de Alimentos, no Departamento de Alimentos e Nutrição, da Universidade Estadual Paulista “Júlio de Mesquita Filho”, Faculdade de Ciências Farmacêuticas, campus Araraquara. Para analisar e comparar as espécies estudadas foram utilizadas amostras “in natura” e congeladas de ambas as espécies e foram determinados os compostos bioativos (carotenoides totais, fenólicos totais e flavonóides totais), ácido ascórbico, acidez total titulável (ATT), atividade sequestrante de radicais livres (DPPH) e sólidos solúveis totais (SST). Todas as análises foram realizados em triplicata. Em todas as determinações, o maracujá doce, Passiflora alata Dryand, apresentou valores menores em relação ao maracujá azedo, Passiflora edulis Sims f. flavicarpa Deg..Os valores demonstram maiores quantidades de antioxidantes em maracujá amarelo em relação ao maracujá doce. Também demonstram que a indicação de consumo para Passiflora alata Dryand, é do fruto “in natura”, uma vez que para haver industrialização e processamento, há necessidade de maior acidez. Já Passiflora edulis Sims f. flavicarpa Deg. demonstra-se adequado para a industrialização.

Brazil is the largest world producer of yellow passion fruit, a fruit crop which is exigent in nutrients, although little studied in relation to phosphorus fertilizing, fundamental on plant establishment. An experiment was carried out during the period of March/2010 to April/2011 in Remigio County, Paraiba State, Brazil, in order to evaluate the vegetative and productive attributes of yellow passion fruit plants under different sources and doses of phosphorus. Treatments were distributed in randomized blocks in tree replications and twelve plants by plot using the factorial design 2 x 5 referring the sources of superphosphate triple and superphosphate simple at levels P2O5 of 0, 12, 18, 24 and 30 g cave(-1). The following variables were recorded: stem diameter, number of productive branches, number of fruits per plant, fruit mass and fruit yield. The sources and doses of phosphorus affected growth and fruit production of yellow passion plants. The triple superphosphate is the most phosphorus efficient source for growth and fruit production of yellow passion fruit. The triple superphosphate dose which promoted the maximum yield of yellow passion fruit is 42.86 g.

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.

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.

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.

The objective of this work was to evaluate the effects of UV-B radiation on the vegetative growth and on the gas exchange characteristics of passion fruit plants (Passiflora edulis) grown in greenhouse. The average unweighted UV-B radiation near the apex of the plants was 8 W m-2 for the UV-B treatment (high UV-B), and 0.8 W m-2 for the control plants (low UV-B). Plants were irradiated with UV-B for 7 hours per day, centered on solar noon, during 16 days. High UV-B radiation resulted in lower shoot dry matter accumulation per plant. The content of UV-B absorbing compounds and anthocyanins was increased in the plants exposed to high UV-B radiation, when compared with the control. UV-B radiation did not affect stomatal conductance or transpiration rate, but reduced photosynthesis and instantaneous water‑use efficiency, and increased intercellular CO2 concentration. The accumulation of UV-B-absorbing compounds and anthocyanins did not effectively shield plants from supplementary UV-B radiation, since the growth and photosynthetic processes were significantly reduced.
