Oenothera Contributions of a Plant to Biology [Paperback]

Because of the great variety of problems which this genus presents to biologists, Oenothera belongs to the best-known genera of plants not used economically. This book summarizes today's knowledge of Oenothera's genetics and related fields like caryology and cytogenetics. It is further of great value for all those whose research topics are based on genetics, such as developmental and evolutionary biology.Because of the great variety of problems which this genus presents to biologists, Oenothera belongs to the best-known genera of plants not used economically.
