FIELD: agriculture.
SUBSTANCE: invention relates to agriculture. Preparation of a mixture of inclusion complexes of 1-methylcyclopropene and methylenecyclopropane in α-cyclodextrin molecules is carried out by passing under pressure of excess of mixture of gaseous 1-methylcyclopropene and methylenecyclopropane through supersaturated aqueous solution of α-cyclodextrin. The mixture may be prepared in the form of a suspension. The composition is obtained by filtration and drying of the suspension. The composition for treatment of apple fruits additionally comprises vegetable oil.
EFFECT: invention enables to improve yield of plants.
