СРАВНИТЕЛЬНЫЙ АНАЛИЗ ИММАТУРНЫХ РАСТЕНИЙ РОДА JUGLANS L., ВЫРАЩЕННЫХ В НИЖЕГОРОДСКОЙ ОБЛАСТИ

The article presents the study data of immature plants of the genus Juglans L., grown under the conditions of introduction in Nizhny Novgorod oblast. The aim of the study has been to determine the growth specifics of Juglans nigra L., Juglans cinerea L., Juglans mandshurica Maxim. at early stages of development. As a result, it has been discovered, that in the conditions of Nizhny Novgorod oblast the species of the genus Juglans L. form seedlings with biometric parameters, corresponding to the requirements of the standard. The formation of the elevated part of the immature plant is mostly influenced by the genetic characteristics of the species, and the diameter of the root collar depends on the sowing date, which has been proved by the results of the variance analysis. It has been empirically determined, that the best sowing date for the nuts is autumn. The linear parameters of immature plants of autumn sowing surpass those of the seedlings, planted in spring.
