What does Extreme environmental conditions such as heat and cold may affect the timing of a mature seed?

Extreme environmental conditions, such as excessive heat or severe cold, can disrupt the natural timing of seed germination and maturation. High temperatures may lead to premature germination, while cold conditions can delay or inhibit the process altogether. These stresses can also impact the seed's viability and overall health, potentially reducing its chances of successful growth. Consequently, extreme weather patterns can adversely affect plant populations and ecosystems.
