Absorption and translocation of chemicals by cotton leaves are greatly increased under conditions of high humidity. This enhanced movement consists of increased phloem transport and induced uptake into and transport via the xylem. Studies with starved and normal leaves prove that phloem transport is greatly reduced in leaves depleted of carbohydrate reserves; starvation has no effect upon the xylem transport induced by high humidity. The relation of high humidity to herbicide usage is discussed. 15 references, 6 figures.
