Resumo: The aim of this research was to characterize and compare two types of calli from leaf explants of Coffea arabica (cultivar Catiguá). Cells of different types of callus were successfully characterized regarding viability and internal and external morphological characteristics. It was obtained two morphologically distinct types of callus: (i) yellow friable and (ii) transparent watery. The yellow friable calli showed higher cell viability and embryogenic characteristics. Scanning and transmission electron microscopy showed embryogenic characteristics in cells of the yellow friable calli evidenced by the presence of small and isodiametric cells, while transparent watery calli showed elongated cells and large cytoplasm vacuolization.

Células de diferentes tipos de calos foram caracterizadas quanto a viabilidade e características morfológicas externas e internas. Foram obtidos dois tipos de calos morfologicamente distintos: (a) amarelo friável e (b) transparente aquoso. Os calos amarelos friáveis apresentaram maior viabilidade celular e características embriogênicas. Microscopia eletrônica de varredura e transmissão mostraram características embriogênicas em calos amarelos friáveis evidenciadas pela presença de células pequenas e isodiamétricas. Os calos transparentes aquosos apresentaram células alongadas e vacuolizadas.Universidade Federal de Santa Maria2018-02-07T12:17:30Z2018-02-07T12:17:30Z2014-04info:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/articleapplication/pdfPÁDUA, M.
