Study of the influence of stratification on germination of sea buckthorn seeds (Hippophae rhamnoides L.) in the conditions of the Moscow region

Abstract

The article presents a comparative analysis of the influence of stratification methods on germination of sea buckthorn seeds (Hippophae rhamnoides L.) in autumn and spring sowing. In the fall sowing with natural stratification under snow, sprouts of H. rhamnoides seeds were more friendly, and the percentage of germination was higher than in the spring sowing with artificial stratification. At autumn sowing of seeds in H. rhamnoides seedlings, formation of many short roots was observed, which predicts more active development of the root system. The number of nodules on the roots of H. rhamnoides plants is formed depending on varietal characteristics and does not depend on the term and method of sowing. Lomonosovskaya, Rossiyanka, Studencheskaya varieties proved to be the most strongly growing in two variants of the experiment at fall sowing, and Trofimovskaya at spring sowing.
