Submitted by Гость (not verified) on Thu, 11/06/2025 - 21:08

Helleborus purpurascens Waldst. & Kit. is a valuable ornamental perennial herbaceous species, highly sought after for shade gardens and exhibiting potential for medicinal applications. While this species has been successfully introduced into various botanical gardens in European Russia, the potential for seed propagation remains understudied. This study aims to identify the developmental features and study the characteristics of seed propagation of H. purpurascens under the conditions of the Central Non-Chernozem region, using Moscow as a case study.

Many plants that are potential producers of medicinal substances, including antitumor substances, are used in landscaping. Taxus L. is one of the such plants. Their fructifications are not only medicinal, but also edible. The aim of the article is to identify of the most promising species of yews for accumulation of dry matter in arils and seeds, as the medicinal and food plants, in the conditions of Moscow region. Morphology-anatomical structure of fructifications of three yew species was studied: T. baccata, T. × media and T.

The pericarp of a sugar beet seed performs the main function of protecting the seed itself from mechanical damage. The pericarp thickness, as well as the seed size and weight depend mainly on the growing conditions of seed plants. Modern technologies for the pre-sowing treatment of sugar beet seeds without fail include the method of removing the external loose parenchyma of the pericarp - defuzzing. This technique is used to obtain greater uniformity of the size and mass characteristics of seeds, to give them a more rounded shape before further pelleting.
