Abstract:
Taking Zoysia matrella as material,the effect of the antioxidative enzymes activities,osmotic regulation substauces and photosynthetic parameters under traffic stress were studied,in order to understand traffic stress mechanism of Zoysia matrella from physiological standpoint.The results showed that net photosynthesis rate(Pn),intercellular CO2 (Ci)and transpiration rate(Tr) of Zoysia matrella decreased with the increasing of traffic stress,but stomatal conductance(Gs) was higher than the control（P<0.05）under moderate and severe traffic stress.Effect of antioxidativ enzymes activities was different under traffic stress.The activities of superoxide dismutase (SOD) of leaves of Zoysia matrella was firstly decreased and then increased,peroxidase (POD),catalase(CAT) firstly increased and then decreased.Zoysia matrella could increase the content of free proline and soluble sugar to change the osmotic potential of cells effectively,thus change its osmotic adjustment ability to resist trampling leads to osmotic stress adapt to under traffic stress.
