Reconstrução de maquetes 3D e manipulação da arquitetura de espécies perenes cultivadas no Brasil

Abstract

Resumo -Este trabalho teve como objetivo indicar algumas possíveis manipulações ecofisiológicas, com base em experimentos de arquitetura de plantas. Plantas de erva-mate, seringueira e videira foram caracterizadas no campo e no laboratório, e suas maquetes 3D foram reconstruídas com os programas V-Plants e PlantGLViewer. Indicações sobre a análise de crescimento e impactos ambientais, com a aplicação de diversas simulações, foram discutidas.Termos para indexação: Hevea brasiliensis, Ilex paraguariensis, Vitis labrusca, arquitetura de plantas, modelagem. Reconstruction of 3D mock-up and architecture manipulation in perennial species cultivated in BrazilAbstract -The objective of this work was to indicate some possible ecophysiological manipulations, based on experiments of plant architectural traits. Yerba-mate, rubber tree and grapevine plants were measured in field and laboratory, and their 3D mock-ups were constructed using V-Plants and PlantGLViewer softwares. Indications about growth and environmental impact analysis were discussed, applying diverse simulations in modeling process.

Software for interpolation of vegetative growth of yerba mate plants in 3D

“…Geometry and topology were included in the multiscale tree graphs -MTGs (Godin et al, 1999), using VPlants (Pradal et al, 2009), a successor of the AMAPmod software (Godin & Guédon, 2003). The MTGs for three growth stages were codified in four scales: plant; trunk, old supports and new branches; growth unit (GU); and internodes (Rakocevic et al, 2008). Branch number and position, internode length, leaf width and lenght and plant photographs were available for the three studied growth stages.…”

Canopy architecture and diurnal CO2 uptake in male and female clones of yerba‐mate cultivated in monoculture and agroforestry

“…SSD in leaf area and light interception are related to leaves positioned in the lowest plant layers . However, sexual responses strongly depend on the environment, especially light conditions, with some opposite effects observed in female and male plants (internode length and individual leaf size), according to whether they were cultivated in MO or in AFS, under high-or lowlight conditions, respectively (Rakocevic et al, 2008;Rakocevic & Martim, 2011;Silva & Rakocevic, 2010).…”
