Abstract/Contents:"The study was conducted to investigate the effect of water and different concentration silicon fertilizer on protective enzyme system and MDA content of turfgrass leaves. Three kinds of turfgrasses, Bermudagrass, Euromyth and Houndog 5,were irrigated by 100%, 75%, 50% of field moisture capacity, and then three turfgrasses were fertilized using 0,28x 10-6,56x 10-6,112x 10-6 silicon acid respectively. The results indicated that SOD, CAT activities of three turfgrasses markedly declined, MDA content markedly increased with drought stress sharper. With silicon concentration increasing, there were no significant changes in SOD,CAT activities, and MDA content of three turfgrasses under FWC100 treatment. However, SOD, CAT activities of three turfgrasses markedly increased and MDA content declined under FWC75 and FWC50 treatments, in particular, under FWC 50 treatment, changes of SOD, CAT activities and MDA content were more distinct. Compared with different concentration silicon fertilizer effects, 56x 10-6 silicon fertilizer had significant effects on improving enzyme activity and decreasing MDA content of three turfgrasses. The changes in protective enzyme activities and MDA content had different due to different drought resistance of three turfgrass species."
