Clonal micropropagation of ovoid forsythia (Forsythia ovata Nakai) and tatar honeysuckle (Lonicera tatarica L.) of the botanical garden of the UGLU USLK named after prof. L. I. Vigorov

Abstract

Woody and shrubby plants in urban conditions play a significant role in creating favorable human living conditions, maintain ecological balance, and form the aesthetic appearance of settlements. One of the main problems in green building can be called a poor choice of tree and shrub vegetation used for urban landscaping. This problem can be solved with the help of introduction.

Plants that have passed a long stage of introduction in botanical gardens are most resistant to local macro– and micro–climatic growing conditions compared to plants imported from abroad, often losing their decorative properties and having low viability in the conditions of the Middle Urals. The introduction of introducers into the culture largely depends on the methods and technologies of reproduction used, among which the most optimal is the method of clonal microreproduction (in vitro). The article considers the reproduction of ovoid Forsythia (Forsythia ovata Nakai) and Tatar Honeysuckle (Lonicera tatarica L.) in vitro. Tatar honeysuckle is decorative throughout the growing season, frost-resistant and drought-resistant, not demanding of care, in addition to decorative, honeysuckle can also have practical significance as an understory in forest parks, suburban forests, forest protection plantations [1], where it will create favorable conditions for nesting of small birds and diversify their food supply [2; 5]. Egg-shaped forsythia is a flowering shrub, blooms immediately after snow melts, blooms for 14 days in the conditions of the Middle Urals, one of the most frost-resistant types of forsythia, can be used in topiary art. Both types are promising for use in urban and private landscaping.
