Summary: | The objective of this work was to evaluate the effects of 26 days of waterlogging, compared with field capacity, on different traits of the forage plants 'Finecut' Chloris gayana, 'Klein Verde' Panicum coloratum, and 'Shawnee' Panicum virgatum, grown in alkaline-sodic soil. Shoot and root dry mass, leaf greenness index, electrolyte leakage, and root histology were evaluated. The histological analysis was performed along the mid-portion of adventitious roots with a 2.0 mm diameter. Waterlogging inhibited the growth of P. coloratum, in addition to decreasing the leaf greenness index and causing injuries in the cell membrane of C. gayana and P. coloratum. At field capacity, only C. gayana and P. coloratum had aerenchyma; however, waterlogging induced the development and increased the area of the aerenchyma in P. virgatum and C. gayana, respectively. Waterlogging also thickened the exodermis and endodermis of all three genotypes, inducing a greater number of exodermis cell rows and a thicker internal tangential cell wall of the endodermis in C. gayana and P. virgatum. Although P. coloratum growth is more sensitive to waterlogging, there are radial oxygen loss barriers in the roots of the three evaluated genotypes. |

Foram avaliados massa seca da parte aérea e da raiz, índice de verdor da folha, extravasamento de eletrólitos e histologia da raiz. A análise histológica foi realizada na porção média de raízes adventícias com 2,0 mm de diâmetro. O alagamento inibiu o crescimento de P. coloratum, além de ter diminuído o índice de verdor foliar e causado lesão da membrana celular em C. gayana e P. coloratum. Em capacidade de campo, apenas C. gayana e P. coloratum apresentaram aerênquima; no entanto, o alagamento induziu o desenvolvimento e o aumento da área do aerênquima em P. coloratum e C. gayana, respectivamente. O alagamento também engrossou a exoderme e a endoderme dos três genótipos, tendo induzido maior número de células da exoderme e maior espessura da parede celular tangencial interna da endoderme em C. gayana e P. virgatum. Embora o crescimento de P. coloratum seja mais sensível ao alagamento, há barreiras radiais de perda de oxigênio nas raízes dos três genótipos avaliados.Pesquisa Agropecuaria BrasileiraPesquisa Agropecuária BrasileiraUniversidad Nacional de Lomas de Zamora (UNLZ)Pesqueira, JulietaKralj, Andrés MolláRovegno, María SoledadLovisolo, Marcelo RamónGarcía, María Dina2023-12-14info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://seer.sct.embrapa.br/index.php/pab/article/view/27521Pesquisa Agropecuaria Brasileira; V.58, Jan./Dec., 2023: Publicação contínua em volume anual; e03118Pesquisa Agropecuária Brasileira; V.58, Jan./Dec., 2023: Publicação contínua em volume anual; e031181678-39210100-104xreponame:Pesquisa Agropecuária Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAenghttps://seer.sct.embrapa.br/index.php/pab/article/view/27521/15255Direitos autorais 2023 Pesquisa Agropecuária Brasileirainfo:eu-repo/semantics/openAccess2023-12-14T19:04:55Zoai:ojs.seer.sct.embrapa.br:article/27521Revistahttp://seer.sct.embrapa.br/index.php/pabPRIhttps://old.scielo.br/oai/scielo-oai.phppab@sct.embrapa.br || sct.pab@embrapa.br1678-39210100-204Xopendoar:2023-12-14T19:04:55Pesquisa Agropecuária Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false |
