Alterações morfofisiológicas e crescimento de helicônias em função de diferentes ambientes de sombreamento

Abstract: A utilização de sombreamento artificial tem sido amplamente empregada na produção de mudas, flores e plantas ornamentais, com o objetivo de minimizar os danos provenientes do excesso de luminosidade. Esta pesquisa avaliou o efeito de diferentes ambientes sombreados [0% (pleno sol); 35% e 50% de sombreamento e sobreposição de telas de 35% + 50%] sobre os aspectos morfofisiológicos e de crescimento de Heliconia psittacorum cv. Golden Torch e Heliconia bihai cv. Humilis em Bom Jesus-PI, no período de agosto de 20… Show more

“…For chlorophyll a/b ratio there were increases up to 65.5% shading with maximum efficiency of 4.02 ICF ( Figure 2D). In this sense, it is evident that the species under study is adapted to high light environments, with marked reductions in chlorophyll a and b indexes, consequently, a higher chlorophyll a/b ratio (TAIZ et al, 2017).…”

“…Given the economic importance of the species to the various regions, ecophysiological studies involving plant growth, development, reproduction and physiology are required. Among the abiotic factors that most influence the plants, the light regime is fundamental to plant growth and development, promoting morphological and physiological changes in response to light, controlling plant metabolism (TAIZ et al, 2017;COSTA et al, 2018).…”
