Селекция однолетних декоративных злаков

Abstract

The results of chemical mutagenes of dymethylsulfate (DMS), nitrosomethylcarbamide (NMC) and nitrosoethylcarbamide (NEC) effect on seeds of ornamental annual graminoides Lagurus ovatus L. , Briza maxima L., Lamarckia aurea (L.) Moench. are presented. Long-term expositions of these mutagenes in most cases negatively influence germinating capacity, germinative energy and seedlings development. Mutagenes effect expanded the spectrum of visible changes and gave an opportunity for distinguishing forms with new ornamental qualities. The forms distinguished are perspective material for further selection.
