- The fluorescence emission efficiencies of Chl a in CP43 and CP47 were calculated to be approximately 38.3% and 40.6%, respectively. 通过理论计算认为在CP43和CP47中 ;叶绿素a的荧光发射效率分别约为 38.;3%25和 40
- POC content has good correlation with chl a ( r=0.889, n=91 ) suggests that POC was mainly from the biological production in the local water columns. POC与叶绿素 a的高度相关性 (r=0 .;889;n=91 )表明普里兹湾 POC主要由 POCB组成即主要来自于浮游植物的贡献。
- The total chlorophyll content(Chl(a+b)),chlorophyll a(Chl a) and b(Chl b) content increased,while the ratio of Chl a to Chl b decreased. 叶片Chl总量、Chl a、Chl b的含量显著增加。
- The result shows that high DIP and COD are the main factors leading to eutrophication ,feature of which is high concentration of Chl a . 结果表明,养殖水体内具有较高的DIP和COD是造成水体富营养化的主要因素。
- L~-1 had more remarkable influence to the content of chl. The contents of chl a b of the former were respectively 17.68% and 15.42% higher than the contrast of the same period. L~(-1)的两个处理对盾叶薯蓣叶片叶绿素的含量影响最为显著;前者叶绿素a、b的含量分别比同期对照高出17.;68%25和13
- The maximum content of chl a of 48.5 mg/g was found in the medium with 1.0 mmol/L urea,and high nitrogen was found to be benefit to biosynthesis of chl a. 0mmol/L尿素培养的D.;salina OUN07叶绿素a含量最高(48
- It is noticeable that the light-harvesting complexes emit at 680-682 nm fluorescence of Chl a when excited at 580 nm,460 nm and 435 nm,indicating that phycobiliproteins in C. 值得注意的是;给予580、460和435 nm的激发光;捕光复合物都可发射680-682 nm Chl a的荧光.
