Abstract

The leaves of plants are their most exposed organs. The thin summer foliage of herbaceous plants and deciduous trees generally suffers so severely that one rarely finds an uninjured leaf. While the degree of wounding is less serious in the evergreens, since they are tougher and offer greater resistance, lesions are not uncommon on these especially on the broader leaved evergreens. The plant's ability, therefore, to deal with such frequent accidents must be highly developed to meet these daily needs for renewed cortex.
