About this book
The impact of drought on crop production can be economically devastating. Drought Adaptation in Cereals provides a comprehensive review of the latest research on the tolerance of cereal crops to water-limited conditions. Renowned experts extensively describe basic concepts and cutting-edge research results to clearly reveal all facets of drought adaptation in cereals. More than simply a fine reference for plant biology and plant improvement under water-limited conditions, this book spotlights the most relevant biological approaches from plant phenotyping to functional genomics.
