Analysis of the features of the pigment complex of leaves of the common ash of the forest-steppe zone

The article presents the results of studying the features of the accumulation of photosynthetic pigments in the leaves of common ash trees growing in the forest-steppe zone of the Central Chernozem Region. It has been established that chlorophyll b dominates in the leaves of all unique ash trees. The content of chlorophyll b is 36% higher than the content of chlorophyll a. The range of variability of the trait for chlorophyll b is in the range of values from 2.44 to 4.34 mg/g a.d.w. It is shown that the level of chlorophyll content in the residues is from 1.42 to 2.72 mg/g a.d.w.
