[null,null,null,"Sommario/riassunto","Drawing from a lifetime of teaching botany, Dr. Nels Lersten presents the study of the structures and processes involved in the reproduction of plants in his text Flowering Plant Embryology. This richly illustrated reference text, with more than 350 figures and illustrations, presents general angiosperm embryology as it applies to economically important plants. The unique focus on economically important species increases the relevance of this book to today's students and researchers in the plant sciences.  Lersten emphasizes the plant species that affect human livelihood, includ"]
