Resumo: | The study of plant behavior in environments with different luminous intensities offers information about their ability to modify their growth and performance in response to light. The objective of this study was to evaluate the influence of shading on the development of Dimorphandra gardneriana Tul. Different levels of shading were used, with 0% shading (full sun) - (T1), 30% - (T2), 50% - (T3) and 70% shading - (T4). The different levels of shading were obtained by means of black polyolefin screens, sombre type, each treatment consisting of four replicates of 15 plants. The evaluated characteristics were: number of leaves, plant height, neck diameter, survival percentage, shoot length and primary root, green and dry mass of shoots and roots, total dry mass, Dickson quality index and (AP/MSPA), shoot height and diameter (A/DC), aerial part and root dry mass (MSPA/MSR), shoot height and dry mass (CPA/CR), as well as the percentage of roots (%R). The shading influenced negatively the quality of D. gardneriana  seedlings, being those grown in full sun the ones that presented the best quality. Based on the morphological parameters studied, it can be affirmed that the D. gardneriana Tul., seedlings, produced in an open environment with high luminosity showed superior qualities in relation to the shaded seedlings. |

Assim, objetivou-se avaliar a influência do sombreamento no desenvolvimento das mudas de Dimorphandra gardneriana Tul. Foram utilizados diferentes níveis de sombreamentos, sendo estes compostos por 0% de sombreamento (pleno sol) - (T1), 30% - (T2), 50% - (T3) e 70% de sombreamento - (T4). A obtenção dos diferentes níveis de sombreamento foi por meio de telas de poliolefinas de cor preta, tipo sombrite, sendo cada tratamento composto por quatro repetições de 15 plantas. As características avaliadas foram: o número de folhas, altura da planta, diâmetro do colo, porcentagem de sobrevivência, comprimento de parte aérea e raiz primária, massa verde e seca da parte aérea e raízes, massa seca total, índice de qualidade de Dickson e a relação entre altura e diâmetro do colo (A/DC), massa seca da parte aérea e das raízes (MSPA/MSR), altura de planta e massa seca da parte aérea (AP/MSPA), comprimento da parte aérea e da raiz primária (CPA/CR), assim como a porcentagem de raízes (%R). O sombreamento influenciou negativamente a qualidade das mudas de D. gardneriana, sendo aquelas cultivadas a pleno sol as que apresentaram melhor qualidade. Com base nos parâmetros morfológicos estudados, pode-se afirmar que as mudas de D. gardneriana Tul., Produzidas em ambiente aberto com alta luminosidade, apresentaram qualidades superiores em relação às plântulas sombreadas.EDUFU2018-10-11info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://seer.ufu.br/index.php/biosciencejournal/article/view/3941210.14393/BJ-v34n5a2018-39412Bioscience Journal ; Vol. 34 No. 5 (2018): Sept./Oct.; 1147-1157Bioscience Journal ; v. 34 n. 5 (2018): Sept./Oct.; 1147-11571981-3163reponame:Bioscience journal (Online)instname:Universidade Federal de Uberlândia (UFU)instacron:UFUenghttps://seer.ufu.br/index.php/biosciencejournal/article/view/39412/24201Brazil; ContemporaryCopyright (c) 2018 Sueli da Silva Santos-Moura, Edna Ursulino Alves, Marina Matias Ursulino, Riselane de Lucena Alcântara Bruno, Antônio Pereira dos Anjos Netohttps://creativecommons.org/licenses/by/4.0info:eu-repo/semantics/openAccessSantos-Moura, Sueli da SilvaAlves, Edna UrsulinoUrsulino, Marina MatiasBruno, Riselane de Lucena AlcântaraAnjos Neto, Antônio Pereira dos2022-02-09T11:28:37Zoai:ojs.www.seer.ufu.br:article/39412Revistahttps://seer.ufu.br/index.php/biosciencejournalPUBhttps://seer.ufu.br/index.php/biosciencejournal/oaibiosciencej@ufu.br||1981-31631516-3725opendoar:2022-02-09T11:28:37Bioscience journal (Online) - Universidade Federal de Uberlândia (UFU)false |
