chla 解釋
葉綠素
  1. Branches and leaves dry weights / roots dry weights is higher in cyclobalanopsis multinervis and michelia foveolta under shading, which revealed that growth of roots were restrained by shading. from june to october, special leaf weights, . chla / chlb and soluble sugar contents were decreased in cyclobalanopsis multinervis and michelia foveolta under shading, but leaf w

    在6月至10月的整個生長季節，遮蔭處理使多脈青岡和金葉含笑的比葉重下降，葉片含水量上升，葉綠素含量上升， chla / chlb下降，類胡蘿卜素含量上升，可溶性蛋白含量上升，可溶性糖含量下降
  2. Carotenoids can make chla return from excited state to ground state by direct or un - direct quenching, in order to prevent algae from photooxidation. on the other hand, it was indicated that polysaccharides have functions in resisting uv. spirulina plalensis can accumulate both cellular and extracellular polysaccharides during uv treatment, it showed highest uv resistant ability ; nanochloropsis sp also can accumulate cellular polysaccharides, while extracellular polysaccharides reduced ; the cellular polysaccharides content of phaeocystis globosa scherffel decreased and extracellular polysaccharides content did not increased markedly, showing lowest uv resistant ability

    鈍頂螺旋藻和微綠球藻中在較低的uv輻射強度下類胡蘿卜素含量升高，而葉綠素a保持相對穩定，說明類胡蘿卜素可能對藻類起到一定保護作用，可能通過直接的或間接的方式猝滅激發態的葉綠素，來保障光合作用的進行；本實驗發現多糖的累積和分泌與藻體的抗uv能力有相關，鈍頂螺旋藻的細胞內和細胞外多糖分泌旺盛，其抗uv能力最強；微綠球藻體內能積累多糖，而胞外多糖分泌減少；球形棕囊藻的胞內多糖含量減少，胞外多糖含量增加也不明顯，其抗uv能力最弱。
  3. Because the pod activity and chla content have good time - effect and dose - effect relationships with pollutants, they both can act as biological and physiological indicators for porphyra haitanensis stressed by environmental pollution

    綜卜nf述否p （ 》寧件龜（ 1下1六二且jj染物問i1一良大的時d 』
  4. And the changes of mortality of somatic cell, chla content, soluble protein content and rna and dna content caused by organophosphorus pesticides, heavy metals and the mixture, show that these environmental pollutants have caused harm to the growth and physiological slate of porphyra haitancnsis

    從k遠來不，作為經濟養則推介? ?一九紫議的產狀和住養價值勢必（引卜廠環境污染； mp馴l 。
  5. Combined toxicity analysis shows that the interactive effect between methmidophos and cd2 + is antagonistic. 3 ) there are good time - effect and dose - effect relationships between the pollutants and chla contents, which is the chla content of most of group decreases with the increasing of dose and prolonging of the exposure, beside exposed the img / l group of cu2 +, the chla content increases with the prolonging of exposure

    除甲胺磷、 cu ~ （ 2 + ）低濃度（ 1mg l ）使chla含量隨污染時間延長而升高外，其它濃度組的污染物均使chla含量隨污染時間延長而降低，表現出良好的時間效應和劑量效應關系。
  6. In the same conditions, the toxicities of pollutants to chla content : phoxim > methmidophos + ccp > cu2f > cd2 + > methmidophos

    說明可溶性蛋白對有機磷農藥較敏感，在0 . 1mg l ，時蛋白含量下降達飽和。
