Allelopathic effects of Festuca arundinacea variety Millennium2 leaf aqueous extracts on seedlings growth of 10 fescue varieties
The allelopathic effects of fescue (Festuca arundinacea) variety ‘Milennium’ 2 leaf aqueous extracts on 10 fescue varieties were assayed. The 50 mg·ml-1 treatment increased the biomass and physiological indices (soluble sugar content, malondialdehyde content and root activity), whereas the 100 mg·ml-1 and 150 mg·ml-1 treatments were inhibitory. There was variable response of fescue varieties to different treatments, the varieties (Aries, Millennium2, and Free star) were most sensitive to the leaf extracts, while Greenlabel, Lenge maste, and Arid3 varieties were least sensitive. The treatments most affected the physiological factor, relative electrolyte leakage, followed by the soluble sugar content, malondialdehyde content, and root activity. These results suggested that sowing an appropriate combination and proportion of grass varieties may be better to improve the lawn quality than the continuous use of a single grass variety.
