ECOLOGICAL SIGNIFICANCE OF RECALCITRANT SEEDS

Recalcitrant seeds, characterized by their sensitivity to d esiccation and inability to withstand
freezing temperatures, play a critical role in maintaining biodiversity and ecosystem
functionality. Unlike orthodox seeds, recalcitrant seeds germinate rapidly after dispersal,
allowing them to adapt to specific envir onmental conditions, particularly in tropical and
subtropical ecosystems. These seeds contribute to ecosystem dynamics through specialized
dispersal strategies, nutrient cycling, and fostering microhabitats that support diverse plant
and animal life. They also enhance ecosystem resilience by promoting rapid regeneration
following disturbances. This paper explores the ecological significance of recalcitrant seeds,
emphasizing their evolutionary adaptations, role in biodiversity maintenance, and
implications for ecosystem stability amidst climate change. The article highlight the need for
targeted conservation strategies to protect recalcitrant seeded species and ensure the
sustainability of the ecosystems they support.
