The role of the antioxidant system in the sustainability of pine plantations in the conditions of a coal dump

The sustainability of pine stands growing in different edaphic conditions of the rock dump of the coal mine on indicators of the antioxidant system and the life of plants was studied. It was revealed that, despite the most adverse edaphic conditions, the maximum stability of pine plantations was marked on the planned dumping site without causing potentially fertile soil layer. This is probably due to more efficient work of the antioxidant system of the needles, which manifests itself in the increase of the content of ascorbic acid and amounts of carotenoids.
