| Abstract |
|
Drought, salt, shade and low temperature is an important environmental stress that adversely affects plant growth and causes a reduction in growth. The study was conducted to clarify the different of oxidative damage to environmental stress with basic species and medium-leaf type of zoysiagrass. Electrolyte leakage(EL), malondialdehyde(MDA) and hydrogen peroxide(H2O2) concentration were determined. This result indicated that low levels of EL, MDA and H2O2 concentration with drought stress for Z. sinica and medium-leaf type of zoysiagrass than Z. japonica and Z. matrella, these has tended to drought-tolerant. Also Z. sinica and medium-leaf type of zoysiagrass decreased the EL, MDA and H2O2 concentration during salt stress, which was investigated for salt-tolerant. In the shade stress conditions were significantly a reduction of MDA and H2O2 concentration in medium-leaf type of zoysiagrass. The findings that decrease of MDA and H2O2 concentration with low temperature stress in medium-leaf type of zoysiagrass. In this study, we investigated the different response of oxidative damage to environmental stress, results indicated that environmental tolerance was higher medium-leaf type than basic species of zoysiagrass. Medium-leaf type zoysiagrass can be utilized for turfgrass breeding of high quality, which needs to be investigated further research at the molecular level. |
