Resumo: This study aimed to evaluate morphological and physiological characteristics of different canafistula progenies (Peltophorum dubium) under different soil water and nutrient availability. The experiment was conducted in greenhouse, under completely randomized design with 12 treatments and four replications, in a factorial scheme 3 (provenance) x 2 (fertilization) x 2 (irrigation). Plant height, stem diameter and SPAD index (soil plant analysis development) were collected throughout the experiment every 15 days. At the end of the experiment, we determined shoot, root and total dry weight, ratio of shoot and root dry matter, leaf water potential and Dickson quality index. Provenances from Serra da Bodoquena and Serra de Maracaju had greater ability to resist water and nutritional stress in relation to Ivinhema, MS provenance. Differences among provenances were intensified when canafistula seedlings were not under water deficit. Water stress imposed on canafistula seedlings causes more morphophysiological damage than stress from lack of nutrients.

O experimento foi conduzido em casa de vegetação, em delineamento experimental inteiramente casualizado, com 12 tratamentos e quatro repetições, dispostos em esquema fatorial 3 (procedências) x 2 (adubações) x 2 (irrigações). Foram coletados dados de altura de plantas, diâmetro do colo e índice SPAD (soil plant analysis development) ao longo do experimento em intervalos de 15 dias. Ao final do experimento foi aferido o peso da matéria seca da parte aérea, de raízes e total, quociente entre matéria seca de parte aérea e matéria seca de raízes, potencial hídrico foliar e índice de qualidade de Dickson. As progênies oriundas da Serra da Bodoquena e Serra de Maracaju demonstraram maior capacidade de resistir ao estresse hídrico e nutricional em relação às progênies da região de Ivinhema, MS. As diferenças entre procedências são intensificadas em ambientes que não proporcionam déficit hídrico para as mudas de canafístula. O estresse hídrico imposto às plantas de canafístula causa mais danos morfofisiológicos do que o estresse por falta de nutrientes.Embrapa Florestas2015-09-30info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://pfb.cnpf.embrapa.br/pfb/index.php/pfb/article/view/88910.4336/2015.pfb.35.83.889Pesquisa Florestal Brasileira; v. 35 n. 83 (2015): jul./set.; 179-188Pesquisa Florestal Brasileira; Vol. 35 No. 83 (2015): jul./set.; 179-1881983-26051809-3647reponame:Pesquisa Florestal Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAporhttps://pfb.cnpf.embrapa.br/pfb/index.php/pfb/article/view/889/426Copyright (c) 2015 Rafael Pelloso de Carvalho, Livia Maria Chamma Davide, Felipe Luis Gomes Borges, Antonio Claudio Davide, Omar Danielhttps://creativecommons.org/licenses/by-nc-nd/4.0info:eu-repo/semantics/openAccessCarvalho, Rafael Pelloso deDavide, Livia Maria ChammaGomes Borges, Felipe LuisDavide, Antonio ClaudioDaniel, Omar2017-04-28T12:42:02Zoai:pfb.cnpf.embrapa.br/pfb:article/889Revistahttps://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:2017-04-28T12:42:02Pesquisa Florestal Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false
