Synopsis Two types of lodging, root lodging and stalk breakage, were observed in potassium‐deficient plants. Root lodging resulted from a small brace root system and subsequent breakdown of parenchyma cells in the brace root. Stalk breakage resulted from parenchyma disintegration in the lower portion of the stalk. This breakdown is illustrated by a series of photomicrographs.
