Morphoanatomy of garcinia madruno (kunth) hammel (clusiaceae) under waterlogged conditions
Garcinia madruno (Kunth) Hammel is a neotropical tree that naturally occurs in terra firme forests and is important as a source of income and medicine for Amazonian populations. This study describes and compares the morphoanatomical responses of plants under conditions of stress and normoxia. Young...

This study describes and compares the morphoanatomical responses of plants under conditions of stress and normoxia. Young plants of Garcinia madruno were subjected to two water regimes: daily controlled irrigation and waterlogged for 84 days. Hypertrophic lenticels, adventitious roots and anatomical characteristics of the roots and leaves were evaluated on days 0, 21, 42, 63 and 84. There were no changes in leaf structure, but cracks and hypertrophic lenticels appeared on the stems, there was an increase in blackness of the roots and the plants formed adventitious roots to adapt to the flooded environment. The anatomical changes in the roots of the flooded plants were thickening of the exodermis in the main root and of the pericycle in the lateral roots, and a large increase in the amount of aerenchyma. Histochemical tests detected starch in the midrib, mesophyll, stem and root of flooded plants, and in the petiole of control plants. In the waterlogged plants, phenolic compounds were found in the petiole and alkaloids were found in the midrib, petiole and root. Garcinia madruno (Kunth) Hammel, árvore neotropical, ocorre naturalmente em florestas de terra firme, considerada uma fonte de renda da população da Amazônia, além de sua importância medicinal do látex para curar diversas doenças. O estudo objetivou descrever e comparar as respostas morfoanatômicas das plantas estressadas e em condições de normoxia. Plantas jovens de Garcinia madruno foram submetidas a dois regimes hídricos: controle irrigado diariamente; e alagado, por 84 dias. Lenticelas hipertróficas, raízes adventícias e características anatômicas da raiz e da folha foram avaliados aos 0; 21; 42; 63 e 84 dias. Não foram observadas modificações na estrutura foliar, no caule surgiram rachaduras e lenticelas hipertróficas, aumento e enegrecimento das raízes, bem como o surgimento de raízes adventícias, como forma de adaptação ao ambiente alagado. As modificações anatômicas nas raízes de plantas alagadas foram o espessamento da exoderme na raiz principal e do periciclo na raiz lateral, além de grande quantidade de aerênquima. Os testes histoquímicos detectaram: amido: nervura central, mesofilo, pecíolo e raiz das plantas alagadas, bem como no pecíolo das controles; apenas nas alagadas foram observados compostos fenólicos no pecíolo e alcaloides: nervura central, pecíolo e raiz. 2018-07-06T13:18:49Z 2018-06-20 2018-07-06T13:18:49Z 2017-01-11 Artigo de Periódico http://repositorio.museu-goeldi.br/handle/mgoeldi/1257 eng Revista Brasileira de Fruticultura Acesso Aberto application/pdf Museu Paraense Emilio Goeldi Brasil MPEG |
