MINOR ELEMENTS AND VITAMIN CONTENT OF PLANTS

Abstract

From a review of literature to date, it seems probable that variations in the ascorbic acid content of plants growing under field conditions will be influenced so markedly by differences between vars. and by climatic conditions that the possible influence of soil conditions and fertilizer practices will be found to have little practical importance. It seems probable, also, that any fertilizer treatment (or lack of treatment) which causes the development of chlorosis in the plant will decrease the carotene content of the leaves. Insufficient information is available concerning the other vitamins to draw any general conclusions.
