Cytoembryological aspects of reduced seed setting in Ranunculus ficaria L. subsp. bulbifer (Marsden-Jones) Lawalrée

Cytoembryological aspects of reduced seed setting in Ranunculus ficaria L. subsp. bulbifer (Marsden-Jones) Lawalrée

Highly disturbed micro- and macro-sporogenesis in R. ficaria L. subsp. bulbifer gives rise to cytologically and genetically unbalanced reproductive cells. In plants from different papulatians, pollen degenerates in various percentages. The majority of apparently normal 7-nucleate ES's undergo a...
