Which is the optimal temperature range for the germination of most seeds?
A seed dormancy mechanism that involves breaking down the seed coat.
Warmth speeds metabolic processes.
Dormancy mechanisms increase seedling survival by allowing germination when conditions are favorable
60 to 80 degrees Fahrenheit
absorption of water
gibberellin
Those seeds require darkness in order to germinate.
