Description
Jinling Feng and colleagues trace aging chemistry in ancient camphor trees during a 2026 study. Leaves came from trees spanning ten to over eight hundred years of age. Polyamines and plant hormones were measured and related to tree age with several statistical methods.
Most measures shifted with age, though three hormones stayed flat. One polyamine fell with age while a cytokinin hormone rose. A free salicylic acid measure tracked closely with the senescence turning point near four hundred fifty years. A three part model predicted tree age reliably. Tree conservators gain chemical markers for judging the health stage of heritage trees.
