The recuperation of areas used during the construction of the hydroelectric plant, especially in 'borrowed areas', is a difficult and long process since all vegetation and the fertile layer of soil were removed. Interventions in these degraded areas could accelerate the revegetation process. The objective of this research was to evaluate the association of arbuscular mycorrhizal fungi (AMF) in tree species, microbial activity (basal respiration) and fertility of 'cerrado' degraded areas. Soil from two areas, pasture soil and exposed subsoil, were utilized. Organic and mineral fertilization, and liming, were added to the pit for better seedlings' initial growth, where 50 mL of preserved cerrado soil was applied as inoculum of microorganisms. Seedlings of 11 tree species were planted: Anadenanthera falcata (Benth.) Speg ('angico-preto'), Acacia polyphylla D. C. ('monjoleiro'), Stryphnodendron adstringens (Mart.) Coville ('barbatimao'), Dimorphandra mollis Benth ('faveiro'), Hymenaea stigonocarpa Mart. ex Hayne ('jatoba-de-cerrado'), Dipteryx alata Vog. ('baru'), Machaerium acutifolium Vogel ('jacaranda-do-campo'), Schinus terebinthifolia Raddi ('aroeirapimenteira'), Magonia pubescens St. Hil. ('tingui'), Lafoensia pacari St. Hil. ('dedaleira') and Tabebuia aurea (Manso) Benth. & Hook ('ipe-amarelo'). Twelve months later, root samples were colleted at the depth of 0-0.10 m and used for evaluations. The subsoil, as compared to pasture soil, was poor in organic matter and presented less microbial activity. The highest mycorrhizal colonization was seen in the species Acacia polyphylla D. C. (monjoleiro), Magonia pubescens St. Hil. (tingui), Hymenaea stigonocarpa Mart. ex Hayne (jatoba-de-cerrado) and Schinus terebinthifolia Raddi (aroeira-pimenteira). These species could be indicated in revegetation projects in 'cerrado' degraded areas. Plants from both areas showed seedlings form high mycorrhizal colonization and low numbers of spores.

Effect of extrusion parameters was studied on the expansion index, specific volume, water absorption index (WAI) and water solubility index (WSI) of expanded yam snacks. The central composite design was used to study the parameters effect. It was verified three levels of temperature in the barrel (100, 115 and 130°C), three levels of screw speed (163, 204 and 245 rpm) and three levels of flour moisture (12, 15 and 18%). The results showed that expansion properties (expansion index and specific volume) depend on flour moisture and extrusion temperature. The WSI was dependant of three parameters. Higher levels of temperature and screw speed increase the water solubility index (WSI). The studied parameters did not influence the water absorption index (WAI).

It was studied the effect of passion fruit genotypes on Dione juno juno (Cramer) (Lepidoptera: Nymphalidae) development. The experiment was carried out in a laboratory, under controlled conditions (temperature: 26 ± 1° C, RH = 60 ± 10% and photophase of 14 hours). Newly-hatched larvae were fed with leaves from different passion fruit genotypes: Passiflora edulis Sims., P. alata Dryand., P. serrato-digitata L., P. edulis f. flavicarpa Deg. ('Sul Brasil'), P. edulis f. flavicarpa, P. edulis f. flavicarpa ('Maguary FB-100') and P. foetida L. Fifty larvae from eggs collected in the field were used per genotype. Larvae were kept on passion fruits branches inside PVC tubes until pupation. Daily observations were performed and branches were replaced whenever necessary. The following parameters were evaluated: duration and viability of larval and pupal phases, larval and pupal weight and adult longevity. The experiment was arranged in randomized blocks design with seven treatments and ten replications. Data were subjected to an ANOVA and means were compared by Tukey test at 5% of probability. The least adequate genotypes for D. juno juno development were P. alata, P. serrato-digitata and P. foetida, showing a high level of antibiosis, while P. edulis, P. edulis f. flavicarpa, 'Maguary FB-100' and 'Sul Brasil' were the most suitable.

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.
