Plant Conservation Genetics

About this book

The conservation and sustainable use of plant genetic resources is of increasing importance globally. "Plant Conservation Genetics" addresses this issue by providing an extensive overview of this emerging area of science, exploring various practical strategies and the latest technology for conservation of plant biodiversity. Leading specialists and experts discuss topics ranging from the science's foundations through every aspect of plant conservation genetics.

This informative text includes several ex situ (outside of natural habitat) and in situ (inside of natural habitat) techniques for plant conservation useful for researchers, educators, and students.
