Boron Deficiency In Flax Linseed
The young leaves are chlorotic and, in cases of severe boron deficiency, the growing points ultimately die and shoots will develop from many nodes. Growth is generally reduced and the stems may be thick, twisted, and possibly fasciated. The tips of the shoots turn yellow, wilt, and die. In old plants, the top part may be affected while the lower part remains healthy. The yield of seed and straw is reduced and the fiber may be of poor quality. Boron-deficient flax appears to be more susceptible to Fusarium than healthy flax. Roots will be dark and short when boron deficiency is severe.
