| The objective of this work was to evaluate the characteristics related to the photosynthetic ability of hybrid and inbred rice varieties, as a way to assess which of the two presented higher potential to stand out under conditions of competition. The trial was set in a greenhouse in completely randomized block design and 2 x 6 factorial scheme with four replications. Factor A consisted of rice varieties (hybrid or inbred) and factor B by competition levels. Treatments consisted in maintaining one plant of either BRS Pelota (inbred) or Inov (hybrid) variety at the center of the plot, under competition with 0, 1, 2, 3, 4 or 5 plants of the variety BRS Pelota at the periphery of the experimental unit, according to the treatment. Fifty days after emergence... |

| ABSTRACT: A pot experiment was carried out for the biological control of charcoal rot on mung bean (Vigna radiata), caused by Macrophomina phaseolina. Pot soil was made sick with an inoculum of M. phaseolina. Dried powdered leaves of Sisymbrium irio, a weed from the Brassicaceae family, were mixed in soil at 1, 2 and 3% (w/w) with and without the application of Trichoderma harzianm, a fungal biological control agent. The highest grain yield (3.62 g pot-1) was recorded in a combined application of T. harzianum and 1% S. irio leaf amendment, which was 62% and 805% higher than negative and positive control treatments, respectively. The application of S. irio leaf amendment and T. harzianum generally enhanced leaf protein, sugar and chlorophyll contents, and... |

| The present study examined changes that took place in the physiology of three species of Rhodophyta by analysing the concentration of pigments and non-structural carbohydrates, comparatively evaluating algae collected from nature and after 28 days of laboratory cultivation. Another objective of the study was to determine whether the species retain their antifungal potential after the period of laboratory cultivation, correlating the changes in physiology and those from bioactivity. After carrying out laboratory cultivation, the results indicated a trend, in the three species of macroalgae, towards a reduction in pigment concentrations, mainly in the phycobiliproteins. For the non-structural carbohydrates no response pattern of the macroalgae was observed... |

| The invasive behaviour of sourgrass (Digitaria insularis) in cultivated areas is due to its strategy of aggressive regeneration, which is based on seed germination. Knowledge of the physiological ecology of this species can contribute to the development of management and control strategies. The aim of this research was to understand the effects of provenance, temperature and light on the germination of sourgrass seeds collected in the Brazilian state of São Paulo in the cities of Americana, Botucatu and São José do Rio Preto and in the state of Paraná in the city of São Miguel do Iguaçu. The seeds were left to germinate at temperatures of 15, 25, 35 and 45 °C, both with and without light. The number of normal seedlings was recorded daily from seven to 60... |

| Abstract This research determined the effect of four nitrogen (N) doses on the nutritional behavior of '(N), potassium (K), phosphorus (P), calcium (Ca) and magnesium (Mg), respectively, in banana Williams, during five plant development stages and two productive cycles. The treatments were as follows: 1) absolute control, 2) 0 N, 3) 161 kg N ha-1, 4) 321.8 kg N ha-1 and 5) 483 kg N ha-1, respectively. A multivariate approach of the differences among cycles was used to adjust the models and eliminate their individual effect, with a randomized complete block design with repeated measurements over time. There were significant differences among plant development stages, with an increase in nutrient accumulation in the banana plant, there were no differences... |

| Gulupa, Passiflora edulis Sims (Passifloraceae), is an important fruit due to its organoleptic and nutritional characteristics and its demand in the international market; however, very few studies have been conducted for studying its Ecophysiology. Until now, this crop has spread throughout the country through empirical knowledge without data that indicate the zones that are more suitable for its cultivation. For this reason, gas exchange, chlorophyll fluorescence (photosystem II operating efficiency and maximum quantum efficiency of photosystem II photochemistry) and leaf water potential were measured in three different locations of Cundinamarca department (Chia [2610 m a.s.l., 14 °C], Granada [2230 m a.s.l., 15 °C] and Tena [2090 m a.s.l., 17 °C]), whose... |

| Plumbago scandens L. is a Brazilian tropical/subtropical species that occurs along the coast. Chemically it is mainly represented by naphthoquinones, flavonoids, terpenoids and steroids. The aim of the present work is to study quantitative changes in the root metabolic production of Plumbago scandens during different physiologic developmental stages relative to floration. The results indicated the presence of four substances in the extracts: plumbagin, epi-isoshinanolone, palmitic acid and sitosterol, independent on developmental stage. The naphthoquinone plumbagin has always showed to be the major component of all extracts. Naphthoquinones exhibited their highest content during floration, while the content of the two others components decreased during... |
