Boron Deficiency in Kenaf

In the early stages of boron deficiency, the kenaf shoots are dark green and the young leaves may be malformed. The midrib and main veins become necrotic which results in the leaf curving backwards. Ultimately, young leaves fail to expand and the shoots die back.

Petiole collapse, caused by an internal necrosis, can cause the death of otherwise normal leaves. Root growth is reduced and roots are short and dark and have thick tips.
