چکیده
O objetivo desta pesquisa foi avaliar a utilização de medições propriedades térmicas e ópticas na caracterização do Gênero Paspalum para em telhados verdes num ambiente tropical. experimento conduzida Universidade Federal Rural Pernambuco - UFRPE Maio Junho 2019. Foi avaliado o número dezesseis acessos com hábitos crescimento vertical ou prostrado. Em condições simuladas um telhado verde, foram avaliadas: Índice Vegetação Ajustada ao Solo (SAVI); temperatura das folhas (L) dossel (C) por termometria (TM); termografia (TG). coeficiente determinação (R2) entre SAVI área cobertura dos 0,84, matéria verde (R2 = 0,73) seca 0,56). Não observada diferença significativa os medição da folha TM TG, TM. No entanto, uma TG Paspalum, temperaturas mais baixas nos hábito que prostado. A relação as técnicas mostrou valores elevados TML TGL 0,85) TMC TGC 0,91). Conclui-se que, pode ser utilizado estimar capacidade vegetal acessos. As copas podem usadas como indicação déficit hídrico utilizando tanto termómetro infravermelhos (mais acessível) câmara termográfica. também utilizada desempenho térmico verdes. imagens termográficas indicaram verticais proporcionar melhor conforto térmico.Palavras-chave: Infravermelho; termografia; termometria; SAVI; fenotipagem; melhoramento plantas. Evaluation of thermal and optical properties measurements paspalum in modular green roof tropical environment B S T R C TThe objective was to evaluate the use characterization genus for on roofs environment. The experiment conducted at – from May June number sixteen accessions with prostrate upright growth habits evaluated. In simulated were evaluated: Soil-Adjusted Vegetation Index leaf canopy temperature by thermometry thermography determination coefficient between coverage area are 0.84, matter 0.73) dry 0.56). significant difference observed measure Nevertheless, observed, lower temperatures habit than those habit. relationship techniques showed high values 0.85) 0.91). Given above, can be used estimate capacity (CC). Leaf an indication water deficit accessions, using both infrared thermometer (more accessible) thermographic camera. Canopy also performance roofs. Thermographic images indicated that may provide better comfort.Keywords: infrared; thermography; thermometry; phenotyping; plant breeding.
