I am just not understanding the chilling hours thing. I found this definition but I still dont get it
Could somebody make that easy to understand? Please.The chilling requirement of a fruit is the minimum period of cold weather after which a fruit-bearing tree will blossom. It is often expressed in chill hours, which can be calculated in different ways, all of which essentially involve adding up the total amount of time in a winter spent at certain temperatures.[1][2]
Biologically, the chilling requirement is a way of ensuring that vernalization happens.
