Sommario/riassunto: | The flowering plants now dominate the terrestrial ecosystems of the planet, and there are good reasons for supposing that the flower itself has been a major contributing factor to the spread of the Angiosperms. The flowers of higher plants not only contain the organs of plant reproduction but are of fundamental importance in giving rise to fruits and seeds which constitute a major component of the human diet.This volume opens with a chapter describing a model for the evolution of the Angiosperm flower. Chapters 2 to 5 describe the core development of the flower and include floral induc |
