Yield and quality of inflorescences of 'Golden Torch' heliconia in different sh...
Souza,Rafaela R. de; Beckmann-Cavalcante,Márkilla Z.; Silva,Alcilane A.; Silva,Everaldo M. da; Brito,Leonardo P. da S.; Silva,Adriano O.ABSTRACT Light is one of the factors that most affect crop growth and yield. However, the control of light intensity is difficult, because, under certain environmental conditions, light energy may exceed or limit the capacity of plants to use it. In this sense, the productive behavior of plant species in shaded environments needs to be known. This study aimed to evaluate the effect of different shaded environme...
Synthesis and evaluation of octocrylene-inspired compounds for UV-filter activity
Polonini,Hudson C.; Lopes,Rosângela S.; Beatriz,Adilson; Gomes,Roberto S.; Silva,Adriano O.; Lima,Ricardo V. de; Nunes,Gláucia. A.Octocrylene (2-ethylhexyl 2-cyano-3,3-diphenyl-2-propenoate) is present in several sunscreens and is known to work synergistically with UV filters. We prepared eight octocrylene-related compounds to test their photoprotective activities by measuring diffuse transmittance. The compounds had varied photoprotection profiles, with Sun Protection Factors (SPF) ranging from 1 to 5 and UVA Protection Factors (UVAPF) r...
