lombhullatóak

Lombhullatóak refers to deciduous plants, a category of flora that sheds its leaves seasonally. This process is a survival adaptation, typically occurring in autumn in temperate climates, though some species in tropical regions may shed leaves during dry seasons. The shedding of leaves helps plants conserve water and energy during periods of unfavorable conditions like cold temperatures or drought.

The color change of leaves before they fall is a well-known phenomenon. As daylight shortens and temperatures cool, chlorophyll, the green pigment responsible for photosynthesis, begins to break down. This reveals other pigments, such as carotenoids (yellows and oranges) and anthocyanins (reds and purples), which were present but masked by chlorophyll. Once the leaves are shed, the plant enters a dormant state until favorable conditions return in the spring or wet season, prompting new growth.

Examples of common deciduous plants include oak trees, maple trees, birch trees, and many flowering shrubs. Their seasonal shedding of leaves significantly impacts forest ecosystems, contributing to soil enrichment as the fallen leaves decompose. This decomposition process returns nutrients to the soil, supporting the growth of new plants and organisms. The visual spectacle of autumn foliage is a major attraction in many parts of the world, drawing tourists and highlighting the cyclical nature of plant life.
