Particularities of propagation of the representatives of Berberis L. family in the setting of the Botanical garden of

Abstract

In modern times plant introduction solves paramount problems of genetic conservation and biological diversity of natural wildflower, including adornment species of plants valuable for cropping. In the course of introduction work it is necessary to assess its success on the basis of reproductive power of reproducible plants. The particularities of propagation by seeds and vegetative propagation of the species of Berberis L. family have been studied in the setting of the Botanical garden of Dnepropetrovsk National University. Quality of seeds and germinating capacity in particular supplement the total characteristic, defining qualitative aspect of the actual seed productivity. Examined species of plants differed according to their indexes of germinating energy and germinating ability of seeds. The species occurring in European, Central Asian, and North Chinese natural areas had high germinating energy and germinating ability of seeds. The method of propagation by herbaceous cuttings, which provides an opportunity to reduce the term of standard seedling production, offers the great challenge for faster propagation of valuable adornment plants and production of top-grade planting material. The species within a family demonstrate different capacity for propagation by herbaceous cuttings. The growth stimulators (fumar, epin and kornevin) enhance root formation of herbaceous cuttings. B. polyantha, B. amurensis, and B. Coreana naturally occurring in European, Central Asian, West Chinese, and Korean areas demonstrated the best result under the influence of biostimulators. The species with high, medium and low degree of root development were distinguished.
