Abstract

Viburnums are of economic importance, are an important component of forests, they are used in landscaping, have medicinal and nutritional value. The purpose of the study is a comparative analysis of characteristics of seeds of 4 viburnum species in the conditions of the Mari El Republic. The authors study the pyrenes collected in 2018-2020 from the plants grown in the exposition "Fruticetum" of the Botanical Garden-Institute of VSUT (Yoshkar-Ola). The mass of 1000 seeds was determined according to GOST 13056.4-67, the sizes of 30 seeds were measured with a caliper. It was found that the studied viburnums form seeds of typical size and weight. Viburnum lentago had the largest seeds, Viburnum lantana had the smallest ones. A significant influence of the species specificity factor on the weight of seeds was revealed, while no significant influence of the factor of weather conditions of different years on the seed indicators was established. The weight of the seeds was very closely positively correlated with their length and significantly with their thickness. The thickness of the seeds was characterized by the highest level of variability, negatively correlated with their width and positively with their length. During the 3 years of the study, the heaviest seeds in most species were formed in 2018.
