These studies suggest that leaf fall in trees is primarily due to chlorophyll degradation and flavonol synthesis during autumn, with atmospheric conditions and frost also influencing the process.

The phenomenon of leaf fall in trees, also known as abscission, is a complex process influenced by various environmental and physiological factors. Understanding the triggers and mechanisms behind leaf fall can provide insights into plant adaptation and survival strategies.
Chlorophyll Degradation and Flavonol Synthesis:
Water Stress and Seasonal Drought:
Early Frost:
Leaf fall in trees is influenced by a combination of factors including rapid chlorophyll degradation and flavonol synthesis, seasonal drought and water stress, and early frost. While chlorophyll degradation and flavonol synthesis are consistent triggers in deciduous trees, water stress and frost can also play significant roles depending on the environmental context.
