| Abstract/Contents: | "Crowfoot grass (Dactyloctenium aegyptium) and seashore paspalum (Paspalum vaginatum), commonly found on the seaside of South China, can be used as turfgrass. In order to probe if crowfoot grass has utilization value, wild seashore paspalum that collected from Hainan Province and the bred variety of seashore paspalum "Salam" were performed as control to evaluate cold resistance of crowfoot grass in this experiment. Under laboratory simulation of temperature conditions in autumn and winter, relative electrical conductivity (REC), malondiadehyde (MDA) content and superoxide dismutase (SOD) activity of leaves were determined. Withering rate during overwintering period under field condition in Nanjing was also observed. The results showed that 25~5°C treatments basically had no impacts on experimental materials and their REC, MDA content and SOD activity had no obvious changes. Under 5~0°C conditions, REC kept essentially constant, SOD activity descended but MDA content increased. Under - 16~0°C treatments, REC of experimental materials increased rapidly, SOD activity descended sharply and MDA content increased with the lower of temperature. Based on the analysis combined with Logistic equation, LT50 of crowfoot grass, Hainan wild seashore paspalum and Salam were -4.2°C,-8°C and -8.1°C respectively. Under field condition, experimental materials started to appear withered gradually since October 26. The withering rate of crowfoot grass was the fastest, Hainan wild seashore paspalum faster and Salam the slowest. The result indicated that cold resistance of crowfoot grass was inferior to seashore paspalum, domestication and breeding of cold resistance aspect should be done if it is used as turf." |
