Última Viability, production and morphology of pollen grains for different species in the genus Manihot (Euphorbiaceae) Acta Botanica Vieira,Lívia de Jesus; Soares,Taliane Leila; Rossi,Mônica Lanzoni; Alves,Alfredo Augusto Cunha; Santos,Francisco de Assis Ribeiro dos; Souza,Fernanda Vidigal Duarte. The objective of this work was to characterize the viability, production and morphology of pollen for different species in the genus Manihot. Floral buds from Manihot accessions were collected from two germplasm banks at Embrapa Cassava & Fruits. The viability of the pollen was assessed via colorimetric, in vitro and in vivo assays. The diameter of the pollen grains was determined by measuring the transversal length of the grain. The experimental design was entirely randomized. Studies on pollen ultrastructure were performed via scanning electron microscopy. Pollen viability was high in the colorimetric tests and intermediate in vivo tests; there was no germination in the in vitro tests. The average production for all accessions was 1,253 pollen...
