Detailed explanation-1: -Seeds require a certain temperature in order to germinate. Each plant has a specific optimum and a range within which germination will occur. The closer the temperature is to optimum, the quicker germination will occur. Most seeds germinate when the soil temperature is between 68° and 86°F.
Detailed explanation-2: -A seed can germinate between 0∘ C to 50∘ C but the optimum temperature for a seed to germinate is 25∘ C to 35∘ C.
Detailed explanation-3: -We predict that increased temperatures will increase germination rates and percentages. However, any temperature past the optimum germination temperature (10-20˚C for many species) (Finch-Savage and Leubner-Metzger 2006) will negatively affect seed germination and species survivability.
