The persistence of higher night-time temperatures (HNT) over long periods during the crop cycle can potentially impact a wide range of growth and developmental stages. The major processes drastically affected by night-time warming, such as photosynthesis, respiration, etc., ultimately cause yield and economic losses. Despite this, HNT has not been significantly researched regarding its impact on plants. This new book provides a comprehensive understanding of the physiology of night-time warming, trait responses, advanced tools for phenotyping, and alleviation and mitigation strategies.
