Chapter 23: A Sense of Time

• in order for trees to drop leaves and regrow (147)

• need a sense of time

• trees don’t green up during warm spells in january or february (148)

• they wait until a certain number of warm days have passed

• also use the length the day

• must have ability to ‘see’

• makes sense for this ability to be in the leaves but in april they don’t have leaves

• is the ability in the buds?

• even agricultural weeds can germinate by the light of the moon

• combination of the length of day and temperature

• trees transplanted from northern to southern hemispheres can adapt

• trees can also get confused

• trees need a sense of time for procreation

• don’t want seeds dropping in fall to germinate

• shoots won’t have time to get woody

• can freeze

• herbivores eat fresh greenery

• seeds register cold

• shoot up after extended warm period

• works great if they get buried by bird or squirrel

• it doesn’t get warm in the soil until well into spring

• light seeds that land on surfaces must register day length
