Abstract

To study the effects of seawater concentration on growth，osmotic accumulation of antioxidant enzymes，and ion distribution with Photinia glabra × Photinia fraseri ‘Red Robin’ and Euonymus japonica ‘Aureo-marginatus’ seedlings，pot experiments were conducted. A randomized complete block design with six treatments consisting of 0%（a control），10%，30%，50%，70%，and 100% seawater and three replicates was used. Plants were harvested 3，6，9，12，and 15 d after treatment and analyzed with ANOVA and multiple comparison for mean separation. Results showed that 1） when seawater concentration was 30% （pH 8.92） for ‘Red Robin’ and 50％（pH 9.12） for ‘Aureo-marginatus’，the configuration changed. Also，2） compared with control plants，superoxide dismutase （SOD） activity was significantly greater （P＜0.05） in leaves of seawater-stressed ‘Aureo-marginatus’，and increased with increasing seawater concentrations. Malondialdehyde （MDA） content in leaves of ‘Red Robin’ increased （P＜0.01） with increasing seawater concentrations but with ‘Aureo-marginatus’ MDA decreased（P＜0.01）. Finally，3） with increasing seawater concentration，Na+ concentrations of the two cultivars increased；K+，Ca2+ and Mg2+ concentrations showed no pattern，but all concentrations were lower than the control. Thus，the present study strongly suggested that the salt resistance of ‘Red Robin’was lower than ‘Aureo-marginatus’；however，because both were alkali-soil plants，they could adapt to appropriate concentrations of seawater irrigation. ［Ch，1 fig. 6 tab. 24 ref.］
