Resumo: The Parkia platycephala Benth. (faveira) is a leguminous tree, known as a provider of commercial wood in the Amazon rain forest. This study aimed to evaluate the effects of different volumes of water for substrate moisture and temperatures on germination of Parkia platycephala. After this, they were sowing over towel paper, organized in rolls wetted with water contents equivalent to 2.0; 2.5; 3.0 and 3.5 times the weight of the substrate without new water addition, and they were maintained in chambers at constant temperatures of 20, 25, 30°C and alternate temperature 20-30°C. The following parameters were analyzed: the germination percentage, first count germination, index of germination speed, length and dry mass of seedlings (shoot and root). A completely randomized design was used with a 4 x 4 factorial (water volumes and temperatures). The moistening of the substrate with 2.0, 2.5, 3.0 and 3.5 times the weight of the paper at temperatures of 25, 30 and 20-30 ºC can be used for germination and vigor of Parkia platycephala Benth. The temperature of 20ºC and all volumes of water tested for wetting the substrate reduced the germination and the vigor of these seeds.

(faveira) é uma leguminosa arbórea, conhecida como fornecedora de madeiracomercial na Amazônia. O presente trabalho foi conduzido com o objetivo de avaliar diferentes volumesde água para umedecimento do substrato e temperaturas na germinação e vigor de sementes de Parkia platycephala. As sementes foram submetidas ao teste de germinação em papel-toalha, organizado naforma de rolos e umedecido com volumes de água equivalentes a 2,0; 2,5; 3,0 e 3,5 vezes o peso seco dosubstrato e colocadas nas temperaturas constantes de 20, 25, 30 e alternada de 20-30°C. Foram avaliados: aporcentagem de germinação, a primeira contagem de germinação e o índice de velocidade de germinação,o comprimento e a massa seca da raiz e da parte aérea das plântulas normais. O delineamento experimentalfoi o inteiramente ao acaso, com os tratamentos distribuídos em esquema fatorial 4 x 4 (quatro volumesde água e quatro temperaturas). O umedecimento do substrato com 2,0; 2,5; 3,0 e 3,5 vezes o peso dopapel nas temperaturas de 25, 30 e 20-30ºC pode ser utilizado para avaliação da germinação e vigor dassementes de Parkia platycephala Benth. A temperatura de 20ºC em todos os volumes de água testados paraumedecimento do substrato reduziu a germinação e o vigor das sementes.Universidade Federal de Santa Maria2015-09-30info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://periodicos.ufsm.br/cienciaflorestal/article/view/1960710.5902/1980509819607Ciência Florestal; Vol. 25 No. 3 (2015); 563-569Ciência Florestal; v. 25 n. 3 (2015); 563-5691980-50980103-9954reponame:Ciência Florestal (Online)instname:Universidade Federal de Santa Maria (UFSM)instacron:UFSMporhttps://periodicos.ufsm.br/cienciaflorestal/article/view/19607/11602Gonçalves, Edilma PereiraFrança, Pablo Radamés Cabral deViana, Jeandson SilvaAlves, Edna UrsulinoGuedes, Roberta SalesLima, Cosmo Rufino deinfo:eu-repo/semantics/openAccess2017-04-10T17:17:57Zoai:ojs.pkp.sfu.ca:article/19607Revistahttp://www.ufsm.br/cienciaflorestal/ONGhttps://old.scielo.br/oai/scielo-oai.php||cienciaflorestal@ufsm.br|| cienciaflorestal@gmail.com|| cf@smail.ufsm.br1980-50980103-9954opendoar:2017-04-10T17:17:57Ciência Florestal (Online) - Universidade Federal de Santa Maria (UFSM)false
