1. Surface morphology and repellency mechanism investigation of Salvinia molesta plant
ABSTRACT Bionics is a versatile tool with a technological potential, which designers use to search for signs and clues about functional elements and mechanisms in nature that allow for the development of products. The purpose of this study was to analyze the morphology of the aquatic plant Salvinia molesta, aiming to determine the water repellency of its lea

2. Does the Use of Adjuvants Alter Surface Tension and Contact Angle of Herbicide Spray Droplets on Leaves of Sida spp.?
RESUMO: O espalhamento das gotas sobre superfícies vegetais pode indicar melhor eficiência numa aplicação de herbicidas. Com este trabalho, objetivou-se avaliar a tensão superficial e o ângulo de contato de gotas do herbicida aminopiralide + fluroxipir associado a adjuvantes sobre a superfície foliar de três espécies do gênero Sida. O experimento f

3. Canopy structure and forage nutritive value of elephantgrass subjected to different stocking rate and N fertilization in the “Mata Seca” ecoregion of Pernambuco
ABSTRACT The objective was to evaluate the effect of three stocking rates (2, 3.9, and 5.8 animal units ha−1) and three fertilization levels (0, 150, and 300 kg N ha−1 yr−1) on herbage mass and nutritive value of elephantgrass (Pennisetum purpureum Schum.) cv. IRI-381. The experiment was conducted from May to August of 2009 and 2010 in Itambé, PE, Bra

4. Evaluation of common bean genotypes for drought tolerance
ABSTRACT The aim of this study was to evaluate twelve genotypes of common bean for intermittent drought stress and for root growth angle. The water deficit experiments were conducted in 2015 and 2016in a randomized block experimental design with split plots and three replications. Two treatments were applied: an irrigated treatment and a water deficit treatm

5. Comparison and correlation analysis of flavonoids and chlorogenic acid contents in different strains of Acer truncatum
Abstract The morphological characteristics, total flavonoid content (TFC) and chlorogenic acid (CGA) contents of leaves from different strains of Acer truncatum were analyzed with the goal of providing guidance for the development and utilization of Acer truncatum leaves (ATLs) and a selection system for the medicinal cultivar of Acer truncatum species. The

6. Morphological Plasticity and Gas Exchange of Ligustrum lucidumW.T. Aiton in Distinct Light Conditions
ABSTRACT The objective of this study was to understand the different morpho-physiological strategies of Ligustrum lucidum, an invasive species occurring in Brazilian forest fragments under heterogeneous light conditions. Ten individuals of L. lucidum were selected and evaluated for morphological of the leaves and physiological traits. For morphological param

7. MORPHOLOGICAL AND GENETIC ANALYSIS OF Triplaris guayaquilensis Wedd (POLYGONACEAE): ONE NATIVE TREE OF ECUADOR
ABSTRACT In this paper, we assessed six native populations (55 trees) of Triplaris guayaquilensis Wedd (Fernan Sanchez), one of the major forest species from Ecuador, using morphological and AFLP (Amplified Fragment Length Polymorphisms) data. The populations were collected through two macro-sites (Central coastals: Quevedo, Ventanas, la Guayas; Andean surro

8. Piata palisade grass deferred with two distinct initial heights: luminous environment and tillering dynamics
The study was carried out between March 1st and July 1st, 2011, in order to evaluate the tillering pattern of the deferred Piata palisade grass (Brachiaria brizantha cv. Piata). Three sward heights were evaluated in the beginning of the period of deferment: lower (20 cm), medium (30 cm) and higher (40 cm). The experimental design was of completely randomized

9. Forage mass and structure of piatã grass deferred at different heights and variable periods
The objective of this study was to determine the deferment period and the most adequate initial sward height of Brachiaria brizantha cv. Piatã for deferment in the region of Viçosa, Minas Gerais. For so, the following characteristics were evaluated: masses and bulk density of forage and its morphological components, light interception by the sward, leaf ar

10. Reanálise CFSR-NCEP aplicada ao modelo SiB2 na simulação de fluxos de CO2 sobre o cultivo de soja em Cruz Alta.
The present work aimed to evaluate the behavior of CO2 fluxes, run by the Simple Biosphere Model (SiB2), by adopting CFSR-NCEP data reanalyzed as an atmospheric boundary condition. A statistical analysis was used in order to validate the results obtained using a coefficient for the adjusted model based on the simulation parameters when compared to the data o

11. Aspectos fisiológicos e da produção do arroz em resposta ao silício / Physiological and productive aspects of rice plants according to silicon supplying
The objective of this study was to analyze the role of supplemental silicon (Si) in the biomass accumulation and grain yield of rice (Oryza sativa L.). Different experiments were carried out in which wild rice plants (japonica subsp. Oochikara - WT) and mutant defective for the absorption of Si - lsi1 (Low silicon rice 1) were raised under hydroponics condit

12. Respostas morfofisiológicas e produtivas de genótipos de Pennisetum purpureum Schum. de porte baixo sob lotação intermitente de ovinos na Zona da Mata de Pernambuco
The research was conducted at the Experimental Station of the Agronomic Institute of Pernambuco (IPA) located in Itambé, dry rainforest region of Pernambuco. The objective was to estimate the coefficients of repeatability, of determination (R2) and the number of measures needed to predict the real value [using principal component analysis (PCA)] to variable
