Studies On Resistance Ecophysiology And Micromorphology Of Eremochloa Ophiuroides And Zoysia Japonica From Anhui Province

5 populations of Eremochloa ophiuroides and 4 populations of Zoysia japonica from Anhui province were studied in terms of resistance ecophysiology. These physiological indexes, including the activity of SOD and POD,relative electrolyte leakage,content of total soluble sugar, proline and total chlorophyll under stress were evaluated. The relationship between ability of tolerance to stress and physiological indexes were subjected to analysis. The results showed that there were significant differences between Eremochloa ophiuroides and Zoysia japonica with respect to drought, cold and trample stress. In general, Zoysia japonica had a good adaptability and lawn value to drought, cold resistance, particularly population transferred from Fuyang in Anhui province, and Eremochloa ophiuroides from Jinhzai in Anhui province was more tolerant to trample stress.The micromorphological features of leaf epidermis and stem were investigated by means of light microscope(LM) and scanning electron microscope(?SEM). The structure of stem and leaf blade showed close relation to the grass drought, trample resistance. In terms of the epidermis, bulliform cell, vascular bundle, and the fibrous girdle of stem, the conclusions that Zoysia japonica from Fuyang in Anhui province was more tolerant to drought, salt and drown stress than the other, Eremochloa ophiuroides from Jinzhai was the best in trample resistance were obtained.Above the conclusions, theory basis about selection of turf-grass for city greening in Anhui province was offered. The maintenance and management about turf was primarily mastered. That will stimulate the development of turf industry in Anhui province.
