• Water makes tree branches droop at night

    15 days ago - By Phys

    A new study using a time-series of terrestrial laser scanning measurements shows that changes in the water status of leaves and branches causes branches to move downward at night, up to 20 cm depending on the tree species. Leaves and branches replenish their water storage during the night, increasing their weight and causing them to droop down. Terrestrial laser scanning is a remote sensing technique that can produce a 3D representation of the surroundings with millimeter accuracy. With repeated measurements, it is possible to study small structural changes in the environment, such as the...
