Investigations were carried out on the leaves and current year stem
increments of three species of fruit trees: apple, sweet cherry, and
common plum. It was found that the stems were photosynthetically active
and capable of photosynthetic CO2
uptake from the outer atmosphere. They reacted to changes in the intensity
of irradiation in a way similar to that of the leaves. The maximum net
photosynthesis of stems was smaller than that of the leaves, amounting to
about 12% in the apple and sweet cherry trees and about 16% in the
common plum trees.
