EKICI, Nuran and DANE, Feruzan. Ultrastructural studies on the sporogenous tissue and anther wall of Leucojum aestivum (amaryllidaceae) in different developmental stages. An. Acad. Bras. Ciênc. [online]. 2012, vol.84, n.4, pp. 951-960. Epub Sep 25, 2012. ISSN 0001-3765. http://dx.doi.org/10.1590/S0001-37652012005000061.
In this study, ultrastructures of anther wall and sporogenous tissue of Leucojum aestivum were investigated during different developmental stages. Cytomictic channels were seen between pollen mother cells during prophase I. Polar distribution was described in the organelle content of pollen mother cells and microspores in early phases of microsporogenesis and also in pollen mitosis. Active secretion was observed in tapetal cells. Previous reports about developmental stages of male gametophyte were compared with the results of this study.
