Resumo: | The objective of this work was to evaluate the physiological aspects of the development of coffee seedlings grown under colored screens with different spectral characteristics. Seedlings of Catucaí Amarelo 2SL, in the stage known as “orelha de onça”, were arranged in a randomized block design, with five replicates, under structures individually covered with blue, white, gray, black or red screens with 50% shade. Four months after, evaluations were done for seedling growth, pigment content of the leaves, total soluble sugars and starch contents of the leaves and roots. The red screen was the most effective in promoting growth in four out of the seven studied traits: plant height, leaf area and leaf dry weight and total dry matter. For the other characteristics, there was no difference among the screens. The pigment analysis showed that, except for the gray screen, the other ones did not differ for this trait. In leaves, the red screen promoted higher levels of carbohydrates and starch. At the root, carbohydrate contents were higher under the red and black screens. Among the five screen colors, the red one was the most efficient in the production of coffee seedlings with higher vigor and quality, with outstanding carbohydrate contents and biomass. |

Mudas de Catucaí Amarelo 2SL, no estádio "orelha de onça", foram dispostas em blocos ao acaso, com cinco repetições, sob estruturas cobertas individualmente com telas nas cores azul, branca, cinza, preta e vermelha, com sombreamento de 50%. Quatro meses depois, foram avaliados: o crescimento das mudas, os teores de pigmentos nas folhas, e os de açúcares solúveis totais e o amido das folhas e raízes. A tela vermelha foi a mais eficiente em promover o crescimento em quatro das sete características estudadas: altura das plantas, área e massa de matéria seca foliar e massa de matéria seca total. Para as demais características, não houve diferença entre as telas. A análise dos pigmentos mostrou que, à exceção da tela cinza, as demais não diferiram entre si quanto a esta característica. Nas folhas, a tela vermelha proporcionou maior teor de açúcar e de amido. Na raiz, os teores de carboidratos foram mais elevados com as telas vermelha e preta. Entre as cinco colorações de tela, a vermelha foi a mais eficiente na produção de mudas de café com maior vigor e qualidade, em que se destacam os teores de carboidrato e a fitomassa.Embrapa Secretaria de Pesquisa e Desenvolvimento Pesquisa Agropecuária Brasileira2020-01-15T12:34:49Z2020-01-15T12:34:49Z2011-05info:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/articleapplication/pdfHENRIQUE, P. de C. et al.
