how plants know when autumn is? Or how they know know when to do seasonal things?
In: Biology
Certain plants go by temperature change. So, in the Southeast we have trees and bushes that will start to bloom if there enough days in a row of over a certain temperature.
Others use the angle of the sun to determine when to start budding. That same angle also indicates when to end photosynthesis in the leaves and that when they die and begin to lose leaves.
I’m sure someone can explain more technically, but that’s my understanding.
