Resumo: | The objective of this work was to correlate data on light microscopy observations through histochemical analysis and polarized light techniques and investigations in transmission electron microscopy (TEM) to characterize the reserve materials in C. peltophoroides Benth. (Leguminosae-Caesalpinoideae) cotyledons, popularly known as "sibipiruna", a tropical tree species with wide distribution in Brazil. The cotyledon mesophyll, especially in the abaxial face, is rich in unsaturated neutral lipids contained in numerous lipid bodies dispersed in the cytoplasm. Proteins, more concentrated in the adaxial face of the cotyledons, occur in all the mesophyll and are stored in protein bodies containing globoids, with variable number and size, responsible for accumulation of mineral reserves. Calcium oxalate druses have distribution restricted to the cotyledons adaxial face and are associated with protein bodies. Starch, also distributed all over the cotyledon mesophyll, occurs in small amounts in plastids with developed lamellar system. Secretory cavities rich in phenolic compounds occur among procambial strands. |

(Leguminosae-Caesalpinoideae), conhecida popularmente como sibipiruna, ou falso pau-brasil, uma espécie tropical com ampla distribuição no Brasil. O mesofilo cotiledonar, especialmente na face abaxial, apresenta-se rico em lipídios neutros, insaturados, contidos em numerosos corpos lipídicos dispersos no citoplasma. As proteínas, mais concentradas na face adaxial dos cotilédones, ocorrem em todo o mesofilo e são armazenadas em corpos proteicos contendo globoides, com número e tamanho variáveis, responsáveis pelo acúmulo de reservas minerais. Drusas de oxalato de cálcio têm distribuição restrita à face adaxial dos cotilédones e estão associadas aos corpos proteicos. O amido, também distribuído por todo o mesofilo cotiledonar, ocorre em pequena quantidade em plastídios, com sistema lamelar desenvolvido. Entre os cordões procambiais ocorrem cavidades secretoras ricas em compostos fenólicos.Revista Árvore2017-12-19T17:19:15Z2017-12-19T17:19:15Z2009-06-23info:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/articlepdfapplication/pdf18069088http://dx.doi.org/10.1590/S0100-67622009000500010http://www.locus.ufv.br/handle/123456789/15709engv. 33, n. 5, p. 873-883, Setembro-Outubro 2009Corte, Viviana BorgesVentrella, Marília ContinBorges, Eduardo Euclydes de Lima ePontes, Claudia AparecidaPinho, Danielinfo:eu-repo/semantics/openAccessreponame:LOCUS Repositório Institucional da UFVinstname:Universidade Federal de Viçosa (UFV)instacron:UFV2024-07-12T07:12:24Zoai:locus.ufv.br:123456789/15709Repositório InstitucionalPUBhttps://www.locus.ufv.br/oai/requestfabiojreis@ufv.bropendoar:21452024-07-12T07:12:24LOCUS Repositório Institucional da UFV - Universidade Federal de Viçosa (UFV)false |
