Early Partial Stomata Closure with Soil Drying

tion, conservation of soil water may result in greater soil evaporation, especially if the top soil layers remain wetter, and the full benefit of sustained plant physiological activity will be lost. Therefore, the relative benefit of the two traits depends on temporal pattern in the rainfall and severity of the drying event. Experimental and simulation studies are presented in the book to indicate the environment conditions and locations where each of the water-conservation traits may result in increased high probability of yield increase. This book offers a review of both water-conservation traits and their potential impact on crop yield. Since there are major differences among crop species, this book is organized to present various crop species individually. These case studies include many of the major global crop species. However, before considering each of the species, the first two chapters background the nature of each of the waterconservation traits. The goal of the book is to provide a report on the current status on the water-conservation traits by partial stomatal closure at earlier stages of soil drying and under elevated VPD. In addition, suggestions for further exploitation of these two traits are discussed.
