Been reading fascinating research articles on bud dormancy of woody perennial fruit trees (e.g. grapes, peaches...).
#Did_you_know that, temperate woody perennial trees have buds that help them overcome freeze injury (low temperatures) through bud dormancy.

... to short-day light conditions (photoperiod) & low temperatures, buds undergo bud dormancy (ceasation of visible growth) & dehydration (to allow for supercooling), in preparation for low temperature experience.

Lack of sufficient chilling requirements is common problem in tropical/sub-tropical regions.
