Abstract
From the rezults obtained the following conclusions can be drawen: Content of carotinoides in individual leves was variabile, the highest was in the middle leaves then in the lower, and least in the upper. With regard to the dynamics, the highest content of carotinoides was observed before silking, whick agrees with the sevent stage of the organogenezis of the ear. The content of carotinoides agrees with that of chlorophyll, both in dynamics and with regard to the content of individual groups of leaves. The content of carotinoides decreases with the density of crops. Content of the amino acids was the highest in the middle and lower leaves, and the to lowest in the upper leaves. The maximum content of free aminoacids was observed on 20 June. Content of aspartic and glutamic acids, as well as alanine, predominated over all other amino acids.
