| 摘 要： | 为了提高暖地型草坪草假俭草(Eremochloa ophiuroides)的抗寒性,延长其青绿期,设置了4个不同乙二胺四乙酸铁-钠(EDTA-Fe)剂量(1、5、10和15 mL/L),对盆栽假俭草进行处理.结果显示,在低温条件下,与空白对照相比,不同处理假俭草叶片的叶绿素、可溶性糖和脯氨酸含量均有不同程度地提高,而其...

| Abstract: | 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. |
