Germination increases in higher temperatures – up to a point. Once the seeds reach optimum temperatures, which depends on the plant, germination begins to decline. ... So whether it's extreme heat or cold, temperature does affect plants and their growth.

Does germination increase temperature?

Our results indicate there is a differentiated effect of temperature on germination between species. Some species show a very positive response to increased temperature, while other species were unaffected.

What is the relationship between germination and temperature?

The germination percentage usually increases linearly with temperature up to an optimal temperature, after which the germination percentage decreases sharply [4–6]. Increased temperatures not only affect seedling growth after seed germination, but also directly affect the germination process.
