中文摘要:
      采用不同浓度的Zn、Cu、Ca溶液对贵州草海流域优势树种华山松、滇杨、白栎等1年生幼苗进行处理,测定不同处理下各植物的碳酸酐酶(CA)活性、叶绿素含量及荧光参数的变化,并分析其光合固碳能力。结果表明:(1)随着Zn浓度的增加,华山 松幼苗的CA活性基本无变化,白栎、滇杨幼苗的CA活性呈上升趋势,3个树种幼苗的叶绿素含量和荧光参数呈增加趋势;(2)随着Cu浓度的增加,华山松幼苗的CA活性基本无变化,白栎、滇杨幼苗的CA活性呈先升高后降低的趋势,3个树种幼苗的叶绿素含量和Y(域)、ETR尧qP尧Fv/Fm 值呈先增加后减少的趋势袁qN 值呈先减小后增大的趋势曰渊3冤随着Ca 浓度的增加袁3 个树种幼苗的CA 活性和叶绿素含量呈先升高后降低的趋势袁Y(域)尧ETR尧qP尧Fv/Fm 值呈先增大后减小的趋势袁qN 值没有太大变化遥说明适量施用Zn尧Cu尧Ca 能够提高植物的CA 活性和光合固碳能力袁这对优化喀斯特岩溶地区植物的固碳能力具有重要意义遥
英文摘要:
      We Used different concentrations of zinc, copper, calcium to deal with three dominant tree species--Pinus armandi, Populus yunnanensis and White oak from Caohai of Guizhou, determinated the carbonic anhydrase activity, chlorophyll content and fluorescence parameters of those plants and analyzed their impacts on the photosynthetic carbon sequestration capacity. The results showed that: (1) With the increase of the concentration of zinc, there was almost no chang in carbonic anhydrase activity of P.armandii,but the carbonic anhydrase activity of P. yunnanensis and White oak increased, the chlorophyll content and fluorescence parameters of the three species also increased. (2) With the increase of the concentration of copper, there was almost no chang in carbonic anhydrase activity of P. armandii, but the carbonic anhydrase activity of P. yunnanensis and White oak increased first and then decreased, the chlorophyll content and the parameter values of Y (域), ETR, qP, Fv/Fm of the three species also increased at first, then decreased.However, the qN of the three species decreased at first, then increased. (3) With the increase of the concentration of calcium, the carbonic anhydrase activity, chlorophyll content and the parameter values of Y (域), ETR, qP, Fv/Fm of the three species increased at first, then decreased. There was almost no chang in the value of qN. Therefore, the application of zinc, copper, calcium can improve the carbonic anhydrase activity and photosynthetic carbon sequestration ability of plant, which is significant to the carbon sequestration ability optimization of the plant in carst areas.
