Stay-Green Trait in Cereals: Physiology Behind Delayed Senescence and Yield Stability
In the realm of cereal crop production, the ability of plants to maintain green foliage during the grain-filling period—known as the stay-green trait—has garnered significant attention. This trait is characterized by delayed leaf senescence, allowing for prolonged photosynthetic activity, which is crucial for sustaining grain development, especially under stress conditions such as drought and heat….
