Observações citológicas em Coffea: XV - Microsporogênese em Coffea arabica L. [PDF]
Bragantia, 1950 No presente trabalho são apresentadas as observações realizadas sôbre a microsporogênese nas variedades semperflorens e caturra, de Coffea arabica L. Notou-se que, no início da prófase, os cromossômios se colorem muito mal, não permitindo observações sôbre a sua morfologia; em paquitene, os cromossômios se apresentam com várias secções heteropicnóticas
