Abstract
Sete acessos da gramínea forrageira Hemarthria altissima, diplóides e tetraplóides africanos e tetraplóides brasileiros, foram analisados com fins de caracterizar, nos diferentes níveis de ploidia, os parâmetros diâmetro dos grãos de pólen e tamanho dos estômatos, com o objetivo de utilizar esses critérios para inferência de níveis de ploidia nessa espécie. As medidas foram feitas com o auxílio de um microscópio com ocular micrométrica. Os resultados demostraram que o diâmetro dos grãos de pólen podem ser utilizados para caracterizar diferentes níveis de ploidia, enquanto que o tamanho dos estômatos não é um critério seguro nessa espécie.
Seven accessions of african diploid and tetraploid and brazilian tetraploid plants of Hemarthria altissima were studied to distinguish, in each ploidy level, the characters of pollen grain diameter and stomatal size. Measurements were performed with ocular micrometer microscope. Results demonstrated that pollen grain diameter can be used to characterize different ploidy levels, but the stomatal size is not a reliable criterion in this species.
