Fig tree (Ficus carica L.) is a fruit of great importance worldwide, being able to be implanted as new source of agricultural variability. The aim of the present work was to characterize the active germplasm bank of fig trees by means of morphological descriptors of 45 fig accessions at the Faculty of Agrarian and Technological Sciences, Campus of Dracena, FCAT / UNESP aiming at the recognition of the quality and genetic variability potential of the species. Thus, their biometric characteristics were evaluated by qualitative and quantitative descriptors of leaves and fruits. Fig tree accessions were characterized by means of the morphological characteristics of leaves and fruits, identifying AGB with high phenotypic variability and well adapted to the region and, by the analysis of the qualitative and quantitative characteristics, it was concluded that the most divergent accessions presented characteristics of agronomic interest, allowing the selection of features in order to subsidize conservation works, genetic improvement and crop production.

Corn and grass intercropping is an interesting practice, and forage plants belonging to the genus Urochloa are the most commonly used in these situations. These plants show excellent adaptation to low-fertility soil, easy establishment, considerable biomass production, as well as being an important competitor with weeds. In agrosilvopastoral systems, the yield of corn crops grown together with trees is hindered due to the reduced radiation incidence caused by tree shading. This study aimed to evaluate corn growth, light interception, and chlorophyll content when intercropped with marandu grass in an agrosilvopastoral system with one and three eucalyptus rows, and compare them with plants under full sun. The experiment was conducted in Andradina - SP (Brazil). Treatments consisted of intercropping with no eucalyptus (plants under full sun: control), one system with one eucalyptus row and another with three rows. We also assessed the effect of five distances between corn plants and eucalyptus trees (2, 4, 6, 8, and 10 m). Between eucalyptus rows, corn plants were intercropped with marandu grass. The analyzed variables were corn plant height, ear height, chlorophyll content index, light interception, dry matter, and fresh and dry forage weights. The experimental design was a randomized block in a factorial scheme plus a control, with four repetitions. Tree arrangements had no influence on corn forage, dry matter, plant height, or ear height. Lower results of yield, dry matter, plant height, and ear height were observed for plants spaced 2 m from trees. In the first two evaluations, significant differences of light interception were found for the different distances. Neither tree arrangements (one and three rows) nor the distances from the trees had any impact on corn heights, with no difference between control and the agrosilvopastoral systems. Neither plant distances from trees nor tree arrangements had an influence on chlorophyll content index of corn plants, with no difference between control and the treatments. As a result, corn growth and forage yield under agroforestry systems are similar in arrangements of 1 and 3 eucalyptus rows (15-month-old trees) and under full sun. However, corn dry matter contents were lower in systems containing trees. Intercropping corn and marandu grass in a system without trees increased light interception at harvest time, indicating a larger soil coverage. Corn forage yield and dry matter content were lower when plants were 2 m apart from eucalyptus trees since this condition provided a lower amount of light and greater competition for water and nutrients.

Citrus black spot (CBS) caused by Guignardia citricarpa is one of the most serious Brazilian citrus diseases. This study aims to assess the interference of three application volumes in spray deposition citrus fruit, as well as fruit growth and rainfall effects on spray deposit reduction during the CBS control period. The experiment was carried out in a commercial citrus orchard, with sixteen-year-old trees of the Valencia variety, in Mogi Guaçu, São Paulo State, Brazil. The spray volumes were: 3.5 (1333L ha-1), 4.5 (1714L ha-1) and 8.5 (3238L ha-1) litres per tree, sprayed by an airblast sprayer using fungicides at recommended periods for disease control. The spray deposition quantification and residue was done by spectrophotometry using a copper oxychloride tracer. Samples were collected in three height zones of the tree (top, middle and bottom) and placed between trees on line plantation. Spray depositions were significantly smaller in the first application as a consequence of reduced fruit size. The spray losses on average for each day of rainfall ranged from 4.0 to 5.7%. There was no significant difference between application volumes regarding spray deposition on citrus fruit,which makes possible the reduction of application volumes, however, it is necessary to improve spraying techniques for the top zone of the citrus tree.

Chemical control efficiency of Asian soybean rust (ASR), besides other factors, is associated with an appropriate fungicide application technique. This study aimed to evaluate the effect of different application technologies on spray deposition and ASR control in 2009-2010 and 2010-2011 crop seasons. The experimental design was a completely randomized block with four replications in a 3×2 factorial scheme. Three application rates were tested (60, 110 and 160 L ha^-1) with and without silicone surfactant addition using a Brilliant Blue dye tracer in spray solution to analyze deposition (Experiment 1). For disease severity, thousand grain weight (TGW) and yield were evaluated on the same experimental design as used in Experiment 1 plus a control (3x2+1). It was used the fungicide mixture of azoxystrobin and epoxiconazol in four replications against ASR (Experiment 2). Application rates and surfactant use did not affect spray deposit levels on middle and bottom plant parts. The fungicide mixture at 160 L ha^-1 was more effective for disease control and showed a greater yield in the 2010-2011 crop season. Chemical control with fungicides and application rates proper to the plant growing stage become essential to ensure a good soybean yield.

The Nepad is a study group that was created recently at Unesp Dracena. It aims to improve the knowledge about floriculture and applied landscaping. The campus of Unesp Dracena is relatively new and it still has landscaped potential to be explored. For a well-designed landscape planning, it is needed prior evaluation of local conditions. This study was developed in order to serve as a basis for future landscaping projects. Its main aim is to carry out a floristic survey of the university campus from Unesp Dracena. In the survey, plants were numbered, located, identified and assessed in relation to their health status. This survey is not completed. However, it is possible to make a preliminary assessment. In total, 380 plants were numbered and 285 plants were identified, at least, into their botanical family level. Up to now, it was identified 14 botanical families. Most of identified plants are native plants, which favors the garden ecological role. It was identified also exotic plants from 10 botanical families. The presence of these exotic plants occurs because there are agricultural sciences courses in this campus of the Unesp. In Brazil, most plants with economic interest are exotic.

This study was carried out at Campo Experimental do Cerrado in Embrapa Amapá, Brazil, aiming to select, based on the agronomic characteristics of productivity, dry matter and nutritional quality of the forage, the accesses of species from the genus Paspalum that possess potentiality of use as forage plants. During the years 2000, 2001 and 2002, 21 accesses of grasses were evaluated, including 18 of Paspalum and three control species: Brachiaria decumbens, Andropogon gayanus cv. Baetí and Brachiaria brizantha cv. Marandú. The experimental design was complete randomized block with three replications. The variables studied were: production of dry matter, neutral detergent fiber on the dry matter, in vitro digestibility of dry matter and crude protein content in the dry matter. All the accesses showed marked reduction in productivity and quality of produced forage, when the climatic conditions became unfavorable, showing that Paspalum as the other tropical grasses have high seasonal production. Based on the variables studied, the selected accesses were P. guenoarum (BRA-014851), P. atratum (BRA-9661) and Paspalum sp. (BRA- 009407).

The concentration of nutrients in plant is related to the soil, fertilization, climate, season, cultivar and cultural practices. Aiming to evaluate the soil chemical properties, the dry matter production of shoots and roots, nutrient content in the plant and the chemical composition of the grass Tierra Verde subjected to levels of organic biofertilizer as nitrogen source, an experiment was conducted in a greenhouse at the Faculty of Veterinary Medicine , UNESP, Araçatuba-SP, January-September 2010. Treatments were arranged in a completely randomized design with six fertilized biofertilizer doses (0, 33, 66, 132, 264, 528 m3 ha-1) and five repetitions for three cuts. We used the model split plot, with doses of biofertilizer considered as main treatments and cuts as sub-plots. We obtained a linear response in the production of dry mass of shoots and roots to the dose of 528 m3 ha-1 of organic biofertilizer. Nitrogen fertilization influenced the soil chemical properties and levels of organic matter, sulfur, boron and manganese, and in foliar levels of phosphorus, potassium and copper. The chemical composition was not altered by the influence of organic biofertilizer doses applied to the soil.

Caracterização das proteínas caveolinas -1 e -2 na placenta de conceptos bovinos clonados transgênicos
(Revista Pesquisa Veterinaria Brasileira, 2015-05-01) Peres, Kenya C. [UNESP]; Trinca, Vitor [UNESP]; Oliveira, Fernanda P. [UNESP]; Oliveira, Lilian J.; Bressan, Fabiana F.; Pimentel, Jose R. V.; Meirelles, Flavio V.; Pereira, Flávia Thomaz Verechia [UNESP]; Universidade Estadual Paulista (Unesp); Michigan State Univ; Universidade de São Paulo (USP)
The transgenic application of green fluorescent protein (GFP) as fetal cell marker on cattle cloned placenta could provide an exclusive model for studying the morphologic and immunologic maternal-fetal interactions, providing information about its mapping, distinguishing the fetal from maternal cells. This model will have direct application, mainly because these animals present problems during its development. With this model's support, we intend to verify the substances transport between mother and fetus during endocytosis, through the immunolocalization of protein named caveolae. For these, we used 06 cloned bovine and 30 cattle samples of artificial insemination (AI) with 90 days of pregnancy, which had been their development interrupted by humanitarian slaughter of the recipient and recovery of the pregnant uterus. We collected the placentome and the chorion. A part of the samples was cut and fixed, by immersion, on a solution containing 4% of parafomaldehyde or 10% of formaldehyde on a sodium phosphate buffer (PBS), at 0,1 M pH 7.4, Zamboni solution (4% of paraformaldehyde, 15% of picric acid, on sodium phosphate buffer 0,1 M pH 7.4), metacarn (60% of metanol, 30% of chloroform, and 10% glacial acetic acid), for morphologic and immunohistochemistry verification for caveolinas proteins -1 and -2 (CAV -1 and CAV-2). The caveolins -1 were found in fetal and maternal villi, but its strongest staining was observed in the endometrial stroma. The caveolins -2 had positive staining in trophoblast and chorioallantoic membrane, and specifically in giant trophoblastic binucleated cell. Therefore the results were compared between cloned cattle and from AI or natural mating, for assisting on detection of the reason of many placental alterations, embryonic losses, spontaneous abortion, post-natal mortality and large offspring syndrome on laboratory-manipulated animals. The result suggests that the proteins caveolins -1 and -2 (CAV-1 and CAV-2) are part of the caveolae composition and important structures related to the molecule transfer to the fetus, nourish it through endocytosis and pinocytosis.

This study aimed to evaluate the use of Pessoa's rein in training equine, as a support in exercise training, on biometry by ultrasonography of the epaxial (Longíssimus Dorsi, Gluteus Medius e Musculus Multifidus) and pelvic musculature (Biceps Femoris e Semitendinosus). Thereby, eight Quarter Horse mares was used, with eight years on average age, 400kg of body weight, trained with the Pessoa's rein twice a week, for two months. Variables were measured before and after training, consisting of assessment thickness (cm) of the Longíssimus Dorsi and cross-sectional area (cm2) of muscles, Gluteus Medius, Biceps Femoris, Semitendinosus and Musculus Multifidus. It observed a significant effect of training with Pessoa's rein, on the Biceps Femoris (P<0.01) and Musculus Multifidus (P<0.01), which the average cross-sectional area at the final evaluation were of 28.66cm2 and 14.29cm2, respectively. Thus it can be conclude that training with Pessoa's rein modifies muscular function, promoting hypertrophy Musculus Multifidus and Biceps Femoris of horses
