Boron deficiency in tung

Symptoms of boron deficiency in tung first appear on the petioles of the young developing leaves as dark green rings, which later become ridges. The young leaves are light green and glossy and the interveinal tissue expands more rapidly than the veins giving the leaves a “puffy” appearance. The leaf veins may crack and become suberized, internodes are short, and terminal and lateral growth stops.
