Treatments were initiated at progressive stages of growth. Leaf injury occurred initially on mature leaves. Symptoms progressed from mild chlorosis of the leaf margins to an eventual necrosis extending inwards 3 to 5 mm from the leaf margin. Mean concn of B in canopy leaves of plants exhibiting incipient symptoms of B toxicity ranged from 125 to 258 ppm. Older plants tended to exhibit B toxicity symptoms at lower foliar concn of B than younger plants.}, number={8}, journal={COMMUNICATIONS IN SOIL SCIENCE AND PLANT ANALYSIS}, author={ELLIOTT, GC and NELSON, PV}, year={1981}, pages={775–783} }
