Resumo: The objective of this study was to identify the response mechanisms to water stress Schizolobium parahyba Vell. Blake seedlings. At 90 days after emergency the plants were subjected to 10 days of water deficit, then they were irrigated with different percentages of evapotranspiration (20, 40, 60, 80 and 100%) for ten more days. In the initial stage of development, seedlings of Schizolobium parahyba were partially tolerant to the caused water deficit. They presented dehydration delay as a strategy, reducing growth in height, diameter and number of leaves and directing the production of photoassimilates for maintenance, with low transpiration rate.

Blake. Aos 90 dias após a emergência, as plantas foram submetidas a 10 dias de déficit hídrico, sendo irrigadas com diferentes porcentagens de evapotranspiração (20, 40, 60, 80 e 100%), por mais dez dias. No estágio inicial de desenvolvimento, as mudas de Schizolobium parahyba apresentaram tolerância parcial ao déficit hídrico causado e apresentaram um atraso na desidratação. Como estratégia de defesa, as plantas reduziram seu crescimento em altura, diâmetro e número de folhas, direcionando a produção de fotoassimilados para sua manutenção, com baixa taxa de transpiração.Embrapa Florestas2020-07-27info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://pfb.cnpf.embrapa.br/pfb/index.php/pfb/article/view/164410.4336/2020.pfb.40e201801644Pesquisa Florestal Brasileira; v. 40 (2020)Pesquisa Florestal Brasileira; Vol. 40 (2020)1983-26051809-3647reponame:Pesquisa Florestal Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAenghttps://pfb.cnpf.embrapa.br/pfb/index.php/pfb/article/view/1644/919Copyright (c) 2020 Autoreshttps://creativecommons.org/licenses/by-nc-nd/4.0info:eu-repo/semantics/openAccessDuarte, Daiane MarquesRocha, Gabriela TeodoroResende, Cecília Leão PereiraSilva, Bruno MeloRodrigues, Fabricio2020-08-28T22:27:15Zoai:pfb.cnpf.embrapa.br/pfb:article/1644Revistahttps://pfb.cnpf.embrapa.br/pfb/index.php/pfb/PUBhttps://pfb.cnpf.embrapa.br/pfb/index.php/pfb/oaipfb@embrapa.br || revista.pfb@gmail.com || patricia.mattos@embrapa.br1983-26051809-3647opendoar:2020-08-28T22:27:15Pesquisa Florestal Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false
