A Phytochemical Physiology Lesson<\/h2>\n

The phenomenon of sap oozing from a cherry tree is more than a cosmetic concern. It is a sign of the physiological processes happening inside the tree, and understanding it can help us care for our tree better. Understanding the mechanisms and compounds involved in sap production unveils a fascinating and complex interplay between multiple elements, often accelerated by environmental extremes. <\/p>\n

The key molecule driving sap production is called auxin. Auxins are hormones produced in the tree’s root tips and canopy needles that regulate multiple growth processes. Auxin concentration levels in any given spot in the tree’s trunk and bark will determine the degree of sap flow. Higher concentrations result in more sap emerging from induced cuts in the bark surface. <\/p>\n

It is understood that auxin is produced in response to environmental cues. Trees may produce it when wound, when stressed for water or when affected by pollutants like smog or excessive use of fertilizers. When trees experience acute cold temperatures, auxin hormones can be induced to travel through the trunk and sapwood and be released from cuts or fissures. This increased production creates the phenomenon of sappy weeping from clearly visible bark exudations. <\/p>\n

In addition to auxin, two other compounds play a major role in sap production: polysaccharides and proteins. Polysaccharides act as a volume-filling substance that gets pushed out of the bark with the sap, while proteins form the act as a structural base for the emergence of the sap. <\/p>\n
