STRUCTURAL-CHANGES DURING THE 1ST DIVISIONS OF EMBRYOS RESULTING FROM ANTHER AND FREE MICROSPORE CULTURE IN BRASSICA-NAPUS

Abstract:

Ultrastructural and cytochemical features of embryo development during anther and free microspore culture in Brassica napus have been followed from the late uninucleate microspore stage through the first embryonic division. On transfer to culture, the microspore cytoplasm possesses a large vacuole, often containing electron opaque aggregates, and a peripheral nucleus. Mitochondria, endoplasmic reticulum and starch-free plastids are distributed throughout the cytoplasm. The conditions of cultu...
