研究叶面喷施不同浓度INH对海滨锦葵光呼吸速率（Pr）的抑制以及对其干鲜重、净光合速率（Pn）、气孔导度（Gs）、胞间CO2浓度（Ci）和PSⅡ光化学特性的影响。结果表明：随着INH浓度的升高,海滨锦葵的Pr、用于电子传递的量子产额（φEO）、电子传递效率（φO）、单位面积内有活性的反应中心数量（RC/CSO）下降,在INH浓度为6 mmol/L时达到最小值;海滨锦葵的干鲜重、Pn、Gs、Ci、以吸收光能为基础的推动力（D.F.）逐渐下降,在INH浓度为4 mmol/L时,较CK差异显著;单位反应中心的热耗散（DIO/RC）增加,在INH浓度为6 mmol/L时,与CK差异显著。抑制植物光呼吸速率后,植物吸收的光能并未明显减少,过剩光能增加,植物出于自我保护增加热耗散。

The paper studied different concentrations of INH sprayed to leaves on the suppression of photorespiration rate of Kosteletzkya virginica（L.）presl and the influences of dry weight,fresh weight,net photosynthetic rate（Pn）,Stomatal conductance（Gs）,Intercellular CO2 concentration（Ci）and photosynthetic characteristics of PSⅡ.The results showed that Pr,φEO,φO and RC/CSO of Kosteletzkya virginica（L.）presl all decreased with the increasing of INH concentrations,with the minimum under the concentration of INH was 6 mmol/L.With the increasing of INH concentrations,dry weight,fresh weight,Pn,Gs,Ci and D.F.all decreased gradually.There was a significant difference compared with the control under the concentration of INH was 4 mmol/L.However,DIO/RC increased with the increasing of INH concentration.There was a significant difference compared with the concentration of INH was 6 mmol/L.The light energy absorbed by plants was not significantly reduced after the inhibition of plant respiration rate,but the excess light energy increased,the heat dissipation increased from self-protection of plants.
