Changes in the content of low-molecular antioxidants and carbohydrates in pinus silvestris, rosa acicularis, ledum palustre in the context of the transition to winter dormancy in Yakutia
Abstract The accumulation of low-molecular antioxidants and carbohydrates in three wintering plants of Yakutia in the summer-autumn period (July, August, September) was studied. Determining the content of the sum of low-molecular antioxidants (LMAO), the sum of flavonoids, ascorbic acid, and the sum...
