Effects of Salt on Photochemical Efficiency of Zoysia matrella Pre-treatment Under Different Light Adaptation

WANG Jiazhen;Department of Biological and Agricultural Technology,Zunyi Normal College;  
Two different light adaptation of Taiwan Zoysia matrella with pre-treatment under strong radiation and extreme shade were employed to study the effects of 0.5 mol·L~(-1) NaCl for 24 days on photochemical efficiency by using chlorophyll fluorenscence technology.The results showed that the Fv/Fm,PhiPSⅡ,Fv′/Fm′,qP and ETR in leaves of two light adaptation types gradually reduced under 0.5 mol·L~(-1) NaCl,NPQ gradually increased,photochemical efficiency gradually reduced and photoinhibition appeared,and photoinhibition increased with the extension of time.Adaptability of the sun-type to salt stress was stronger than the shade-type.
