Vegetative Reproduction of Russian Species of the Genus Myricaria Desv.
E. M. Lyakh
Abstract
Species of the genus Myricaria Desv. (fam. Tamaricaceae) are valuable decorative, fodder, technical and medicinal plants. Siberian populations are localized in the most northern part of the areal and have a great importance in the conservation of the genetic pool as the most adapted to the conditions of extreme continental climate. At present, as a result of geological explorative and road-building works, the natural habitats of the species of Myricaria Desv. are being destroyed. In this connection, protection of all the known habitats and conservation of the genetic pool of these species in botanical gardens are necessary. An acute necessity arises to study the ways of reproduction and in the first place vegetative one, since the seeds of mericariae are very small and rapidly loose their germinating capacity. Besides, the vegetative reproduction permits conservating the genetic pool not only of species, but also of all intraspecific forms, including those especially valuable for introduction of northern populations. In the paper, recommendations developed at the Central Siberian Botanical Garden for vegetative reproduction of Myricaria Desv. (Tamaricaceae) species using lignified cuttings with various substrates and cutting and sowing time are presented
