| Abstract The genus Physalis L. has great importance in the framework of Brazilian biodiversity especially in the Amazon region. The use of colored shading nets allow manipulating the light spectrum, and thus supplying the appropriate quantity and quality of light for each species and maximizing production. The purpose of this study was to evaluate the effects of shade nets on fruit production and qualitative parameters of four species belonging to genus Physalis. The experimental design was random blocks with a 4 x 5 factorial scheme, four species of Physalis (P. peruviana, P. pubescens, P. minima and P. ixocarpa) and four colors of shade nets (white, blue, red and black), besides the control treatment under full sun exposure. Fruits were collected weekly... |

| ABSTRACT To support breeding programs of pear tree, on the selection of cultivars to subtropical area in Brazil, the objective of this research was to adjust the growth medium basic to pollen grain germination. The pollen grains of 'D'Água' cultivar were spread on the surface of Petri dishes containing 20 ml of culture medium in accordance with the following sequential experiments: 1) ágar (4; 6; 8 and 10 g L-1) and pH (3,5; 4,5; 5,5 and 6,5); 2) sucrose (0; 30; 60 and 90 g L-1); 3) calcium nitrate (0; 200; 400 and 800 mg L-1); 4) boric acid (0; 400; 800 and 1200 mg L-1); 5) temperature of incubation (15; 20; 25 e 30 ºC) and 6) emission time of the pollen tube (0; 1; 2; 3; 4; 5 and 6 hours after inoculation). After incubation, the germination rate of... |

| RESUMO O objetivo do trabalho foi elaborar um meio de cultura para avaliação da viabilidade polínica e determinar o número de grãos de pólen por antera e por flor de espécies de fisális. O trabalho foi desenvolvido de forma sequencial, onde grãos de pólen de Physalis (P. angulata,P. ixocarpa,P. minima,P. peruviana e P. pubescens) foram submetidos à germinação em meio de cultura desenvolvido em quatro fases: verificação da concentração de ágar e pH, concentração de sacarose, nitrato de cálcio e ácido bórico. Para a contagem de grãos de pólen, cinco anteras foram coletadas entre cinco espécimes representativos de cada espécie, deixadas em repouso para ocorrência da deiscência e posteriormente adicionado ácido lático, para melhoria da visualização do grão de... |

| ABSTRACT The aim of this study was to analyze the effect of colored-shade nets on the physicochemical characteristics of physalis in subtropical area. The experimental design was the randomized blocks with a 4 × 5 factorial, being four species of physalis (Physalis peruviana, P. pubescens, P. minima and P. ixocarpa) and four net colors (white, blue, red and black), besides the control under full sun. Titratable acidity (TA), pH, vitamin C, soluble solids (SS), SS/TA relation, total phenolics, anthocyanins and antioxidant capacity were evaluated. It was observed that P. peruviana and P. pubescens have more acid fruits, and P. minima shows vitamin C content higher than the other species. In general, fruits of P. peruviana and P. pubescens have better quality... |

| RESUMO O cambucizeiro (Campomanesia phaea), pertencente à família Myrtaceae, é uma planta nativa da Mata Atlântica brasileira. A descrição das características dos frutos de cambucizeiro é importante para subsidiar novos trabalhos de melhoramento genético e sua exploração comercial, principalmente no que tange ao processamento dos frutos. O presente trabalho teve como objetivo realizar a caracterização morfológica e química de frutos de cambucizeiro. Cinquenta e oito acessos, oriundos de diferentes locais da Mata Atlântica e Serra do Mar paulista, foram coletados, propagados por sementes e um exemplar de cada acesso encontra-se no Núcleo de Produção de Mudas de São Bento do Sapucaí (SP). Quarenta frutos de cada acesso foram coletados no mês de maio e... |

| ABSTRACT: The commercial propagation of rose bushes is carried out asexually by the cutting method. The genetic material and the substrate are factors that interfere in the rhizogenic process of the cuttings. Thus, the aim of this work was to evaluate the effect of the substrate on the rooting of cuttings of two hybrid rose bushes. Floriferous branches of matrix plants were cut at the apex and at the base, approximately 8cm long and with two buds, and the basal leaf was removed. The experimental design was completely randomized, in a 2 × 3 factorial scheme (two cultivars, Tineke and Natal Briar × three substrates, carbonized rice husk, coconut fiber and TN Gold®) containing four replicates of 15 cuttings per replicate. The base of the cuttings was immersed... |

| ABSTRACT: The framboseira-negra has a potential for cultivation in Brazil, due to the fact that this fruit produces high quantities of fruits, which confer a high quality jelly. However, their propagation is an obstacle to the establishment of commercial plantations. Production and expansion of a fruit is directly linked to the propagation method and the quality of its development. Given the above, the aim of the present study was to evaluate the use of stem cuttings and IBA in asexual propagation of black raspberry. Two experiments being conducted in greenhouse conditions were performed. Stem cuttings were taken from didactic orchard, with matrix plant of four years, which were the experiments. The first experiment was carried out in factorial 3x2, with... |
