Английская Википедия:Grafting wax
Материал из Онлайн справочника
Grafting wax is a composition of rosin, beeswax, tallow, and similar materials,[1] used in gluing and sealing the wounds of newly grafted trees or shrubs[2] to protect them from infection. The current formulation typically used in the northwestern portion of the United States for fruit trees, is based on a mixture created by Albert Sak, a German-from-Russia immigrant. The exact original composition is a closely guarded family secret.
