Regenerative ability of slender speedwell (Veronica filiformis SM.)
Šerá, Božena
The experiment was focused on clonal development of Slender speedwell (Veronica filiformis Sm.) from small cutting stems without using of stimulative agents. Short stems from four various part of aboveground body were cultivated: main terminal part, secondary terminal part, small nodes, and big nodes. All different vegetative parts were able to produce roots, take roots in soil substrate and in semi-natural meadow, survive winter, and make flower. The species was more successful in company with these meadow plants: Lotus corniculatus, Medicago lupulina, Achillea millefolium, Plantago lanceolata, Taraxacum sect. Ruderalia, Trifolium repens and Crepis biennis. The best growth was confirmed for both of main and lateral terminal parts. These terminal segments had the greatest number of survived individuals, flowering stem, and weigh of dried parts.
