  2. The maize and neorgelia cawlinae meyendor ffii were treated with uv - b radiation with the intensities of 0uw. cm - 2 ( ck ), 10uw. cm - 2 ( r1 ) and 15uw. cm - 2 ( r2 ), the duration of uv - b treatment were ten hours per day ( from am8 : 00 to pm18 : 00 ). the effect of uv - b radiation on the photosynthesis was studied, and the results showed as follows : ( l ) the effects of uv - b radiation on photosynthesis of maize and neorgelia cawlinae meyendor ffii the results of the experiment show that the photosynthesis of maize seedlings was restrained because of the decrease of chlorophyll contents activity of hill reaction stamotal conductance activity of pepcase and atp content caused by increased uv - b radiation, and it was more restrained under higher uv - b radiation. though the activities of rubpcase and pepcase were decreased, the chlorophyll contents activity of hill reaction stamotal conductance of mature maize were not affected, therefore the photosynthesis of grown - up plant was not affected

    Cm ~ （ - 2 ） （ r2組）的uv - b輻射，每天處理10小時（ 8 ： 00 ? 18 ： 00 ） ，直至玉米成熟，以自然光照為對照（ ck組） ，對增強uv - b輻射條件下玉米和紅彩鳳梨光合作用的響應作了深入的研究和探討，結果如下： （ 1 ） uv - b輻射對玉米和紅彩鳳梨光合作用的影響研究結果表明，因增強uv - b輻射降低了玉米幼苗葉片的葉綠素含量、 hill反應活力、氣孔導度、 pepcase活性和atp含量，從而影響了玉米幼苗的光合作用，使其光合速率下降，且隨uv - b輻射強度的增加其影響程度加大；而玉米成株在增強uv - b輻射環境下其葉綠素含量、 hill反應活力、氣孔導度等未受影響，雖然其rubpcase活性和pepcase活性有所下降，但總體上其光合作用受到的影響不大。
  3. Effects of cd on growth, photochmecal efficiency, chlorophyll content and net photosynthesis of canna indica linn and rumex acetosa l were studied so that the theoretical basis of phytoremediation of pollution by cd could be provided

    ）為實驗材料，研究cd脅迫對美人蕉和酸模的生長、光化學效率、葉綠素含量以及凈光合強度等生理指標的影響，探討cd對高等植物的毒害效應，以期為重金屬cd污染的植物修復技術提供理論依據。
  4. Characterization of chlorophyll fluorescence in a mutant of brassica chinensis l. with xantha seedling leaves

    黃苗突變體的葉綠素熒光特性栽
  5. It meaned that simulated acid rain made the toxic effects of zn or cd on growth of the plants more serious. the fresh weights and chlorophyll contents of phaseolus vulgaris l were the highest when ph value of acid rain was 4. 5, zn concentration was 60 mg / kg, and or cd concentration was 0. 5 mg / kg. this showed that lower acidity of simulated acid rain and lower concentrations of zn or cd could promote growth of the plants

    本試驗中，酸雨加zn或者酸雨加cd使小白菜鮮重小於單一污染處理，說明酸雨增加了zn 、 cd對小白菜的毒害作用；而當酸雨ph值為4 . 5 、 zn濃度為20mg / kg或cd濃度為0 . 5mg / kg時，四季豆鮮重達到最大值，這表明低強度的酸雨和低濃度的zn 、 cd促進四季豆的生長。
  6. In this dissertation, effects of different acidities of simulated acid rain and different concentrations of zn or cd on the fresh weights, contents of chlorophyll, activities of sod, pod, cat, and contents of mda in brassica chinensis l and phaseolus vulgaris l were studied with a pot experiment. the main results were as follows : the contents of chlorophyll of brassica chinensis l and phaseolus vulgaris l had the same tendency as the biomass of these two plants treated with simulated acid rain, zn and cd. the fresh weights and contents of chlorophyll of brassica chinensis l decreased with increasing in concentrations of zn, cd and acidity of simulated acid rain

    本文通過盆栽試驗，研究了不同強度的模擬酸雨和不同濃度的zn 、 cd對小白菜、四季豆生長量、葉綠素含量、根和葉保護酶活性以及mda含量的影響，主要研究結果如下：在模擬酸雨和zn 、 cd的脅迫下，小白菜、四季豆葉綠素含量與其生長量有著相同的變化趨勢，其中小白菜鮮重和葉綠素含量隨著zn 、 cd濃度以及酸雨強度的增加而減小，四季豆鮮重和葉綠素含量隨著zn 、 cd濃度以及酸雨強度的增加先升高後下降。
