Chlorosis, the loss of green pigmentation in foliage, manifests as a yellowing of plant tissues. In fruit trees, this discoloration often signals underlying physiological imbalances. For instance, a common occurrence sees the foliage of a Malus domestica specimen transitioning from a vibrant green to a pale yellow hue.
Recognizing and addressing the causative factors is crucial for orchard health. Untreated, the condition can impede the tree’s ability to photosynthesize, leading to reduced fruit production, weakened growth, and increased susceptibility to disease and pests. Historically, observation of foliage color has been a primary diagnostic tool in fruit cultivation.
