Estabelecimento de meio de cultura e quantificação da germinação de grãos de pólen de cultivares de marmeleiros

Abstract: Visando a dar suporte aos trabalhos de melhoramento genético do marmeleiro (Cydoniaoblonga Mill.), voltados para a seleção de cultivares altamente produtivas, aptas a serem cultivadas em regiões subtropicais e produtoras de doces de qualidade superior, objetivou-se ajustar o meio de cultura básico para a germinação de grãos de pólen de diferentes cultivares dessa espécie e quantificar o número de estames, número de grãos de pólen por antera e por flor. O pólen utilizado foi da cultivar Portugal, obtido de ante… Show more

“…Thereafter, each pair of anthers was removed and stored separately in uncapped Eppendorf tubes at a controlled temperature (27 °C) for 24 h in the absence of light to allow for dehiscence and pollen grain release, according to the recommendations of Ramos et al (2008) and Zambon et al (2014).…”

“…After 24 h a solution of 1,000 µL of lactic acid was added to the Eppendorf tubes and after 48 h a sample of 10 µL from each tube was placed onto a counting chamber (Neubauer) to determine the number of pollen grains with the aid of an optical microscope with 100x objective lens (Zambon et al 2014).…”

“…Houve aumento na porcentagem de grãos de pólen que emitiram tubo polínico até sete horas pós-inoculação (40,63% de germinação) (Figura 1e). Segundo Gaaliche et al (2013) e Zambon et al (2014), há aumento na porcentagem de germinação dos grãos de pólen no decorrer do tempo de incubação.…”
