Effect of EDTAFe on chilling resistance and green period of centipedegrass (Eremochloa ophiuroides)

A pot experiment was conducted to determine the effect of different concentration EDTAFe (0, 1, 5, 10 and 15 mL/L) on chilling resistance and green period of centipedegrass strain E126 (Eremochloa ophiuroides). This study indicated that EDTAFe treatment reduced the electrical conductivity, increased the chlorophyll contents and restrained the chlorophyll decomposition, increased soluble sugar and proline content of centipedegrass under low temperature condition, implying that EDTAFe treatment improved chilling resistance. The concentration of EDTAFe with 10 mL/L was optimal and prolonging green period of centipedegrass for 15 days.
