Abstract
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. canadensis, their size-weight characteristics and dry matter content were revealed. The fructifications of the studied species are morphologically similar to each other. The fructifications, arils and seeds of T. × media and T. baccata are larger than those of T. canadensis, have a high mass and air-dry matter content. The total dry matter content in fructifications of T. baccata is 32%, in T. × media – 35%, in T. canadensis – 63%; seeds account for 7%, 8% and 45%, respectively, and arils – 25%, 27% and 18%. Based on the dry matter content of fructifications and/or seeds, T. canadensis seems to be more promising among the species studied. If edible aril is considered as a part of the fructification that is promising for food use, T. baccata and T. × media may be favoured.
