The objective of this research was to evaluate the influence of biodegradable carboxymethylcellulose-based composition on the growth characteristics of coated corn seeds during storage. The seeds of four corn hybrids (P280, P300, P398, P402) were coated with a carboxymethylcellulose-based composition containing an extract of phenolic compounds from Juniperus sabina and natural dye obtained from Phytolacca americana berries. Early growth characteristics (germination, root/shoot lengths, root/shoot biomass, root/seedling vigour, metabolic efficiency) of coated seeds were studied before storage and during four months of storage. During storage, the overall germination of seeds remained at the level of 94-98%, while the length of the roots and seedlings of the germinated seeds increased by 1.2-1.9 and 1.4-1.8 times, respectively. After storage, the coated seeds also showed an increase in the vigour of roots and seedlings (by 1.5-2.1 times). Thus, the developed composition contributes to the improvement of the growth characteristics of corn seeds and, due to the original dye, allows for easy identification of coated seeds.
