Profile

Led Eucommia cultivation trials on the Black Sea coast and drafted the Soviet regulations for establishing Eucommia seed stands.

Story

Leshchenko worked at the state forestry research institute in Sochi (SOCHNIILOS) and was responsible for cultivation technology in the Soviet Union's Eucommia industrialization. Between 1949 and 1954 he systematically observed the growth, fruiting, and overwintering of Eucommia on the Black Sea coast; his surviving 151-page trial report remains primary-source material for studying this period.

The seed-stand regulations he issued in 1952 moved Eucommia from trial planting to standardized silviculture, and his Eucommia entry for the Sochi Arboretum book brought the species into the Soviet dendrological textbook tradition. A 2020 Eucommia research paper in the bulletin of Moscow State University's botanical garden still lists his work as a core reference.
