Изменчивость Lagurus ovatus L. под влиянием диметилсульфата (ДМС)

Abstract

The results of examining the effect of dimethylsulphate (DMS) upon the Lagurus ovatus seeds are expounded. It is determined, that the treatment of the seeds by 0,01% DMS with 6 and 18 hours’ exposure and by the concentration of 0,05% with the exposure of 6 hours stimulates seed germination, but does not effect leaf, panicle and generative shoots size. Seeds exposure to 0,005% concentration of DMS during 18 hours inhibits seed germination, but positively increases generative shoots height, panicle and leaf size, causes appearing of branchy forms. As a result of the research, hare’s tail grass forms perspective for the further selective work, have been singled out.
