  2. In this paper, kandelia candel ( l. ) druce hypocotyls were cultivated in sand and treated with 15 % seawater for 60 days under laboratory conditions. the influence of increasing concentrations of napthalene and pyrene ( 0, 0. 1, 1 and 10mg / l ) on hypocotyl germination and growth, photosynthesis metabolism, water metabolism and membrane protection system were observed to inquire into the ecophysiological responses of mangrove k. candel to pahs phytotoxicity. moreover, the concentration and distribution of parent polycyclic aromatic hydrocarbons ( pah ' s ) in surface sediment, underground root and leaf residue of mangroves in jiulong river estuary ( fugong, north and south shores of haimen island, baijiao ), neighbouring xiamen western harbour ( dong islet ) and dongzui harbour ( fenglin ) were examined

    在實驗室條件下,分別以0 . 1 、 1和10mg l的萘( nap )和芘( pyr ) 3個梯度濃度組級砂基培養秋茄( kandeliacandel ( l . ) druce )幼苗,培養基鹽度15 ,培養期60d ,以不加pahs為對照,分析了nap和pyr對紅樹植物秋茄幼苗的生長、光合代謝、水分代謝以及膜保護系統的影響,探討pahs對紅樹植物秋茄的的生理生態效應及植物性毒害( phytotoxicity )的機理。
  3. Changes in concentrations of boron ( b ) and magnesium ( mg ) in the ovary ( fruitlet ), rind and pulp of fruit were investigated throughout fruit development of parthenocarpic kamei satsuma mandarin ( citrus unshiu marc. ) and self - pollinated egan 1 tangerine ( c. reticulata blanco ). the results showed as follows : 1 ) b concentrations in the ovary of kamei were at high levels before flowering and at full bloom, and decreased after flowering, whereas that of egan 1 was relatively low at full bloom, thereafter significantly increased. no significant differences were observed in mg changes in the ovary ( fruitlet ) between the two cultivars, which presented decreasing trends after flowering. 2 ) minor changes of b concentrations in the rind of the two cultivars were detected, remarkable changes were found for b in the pulp, which came to the peak values during the stage of fruit enlargement. mg concentrations were relatively high in the rind and pulp of the two cultivars during early fruit development, and presented obviously declining trends during the middle and late stage of fruit development

    以單性結實的龜井溫州蜜柑和自花授粉結實的鄂柑1號橘為試材,對整個果實發育期的子房(幼果) 、果皮和果肉的硼鎂含量變化進行了測定.結果表明: 1 )龜井花前至花期子房硼含量就已較高,花後下降;而鄂柑1號花期子房硼含量相對較低,花後有一顯著上升;兩品種子房(幼果)鎂含量變化無明顯差異,花后均趨下降. 2 )兩品種果皮硼含量變幅較小,而果肉硼含量變幅相對較大,且均在果實膨大期出現明顯的上升高峰;兩品種果皮和果肉鎂含量在果實發育前期均相對較高,在果實發育的中後期則趨明顯下降
  4. 2. the relationships between the nutrients exchange rates and the potential environmental controls it was observed that the exchange rates of sio3 - si were correlated with the temperature, do, ph, salinity of the seawater, the water and clay contents of the sediments and the concentrations of sio3 - si in the overlying water and pore water of the sediments

    2 、影響營養鹽在東海沉積物一海水界面交換速率的主要因素sio _ 3 - si在東海沉積物?海水界面交換速率與水體溫度、 do濃度、 ph值、鹽度、沉積物的含水率、粘土礦物含量、間隙水中sio _ 3 - si濃度、上覆水中sio _ 3 - si濃度均存在很好的相關性。
  5. Methods : a self - made sensing needle was used to measure calcium ion concentrations of dachangshu ( bl25 ), ganshu ( bli8 ) and guangyuanshu ( bl26 ) and their corresponding non - acupoints in 8 sheep ; oxygen partial pressure of ganshu ( bl18 ) and housanli ( ex ) and their corresponding non - acupoints were also observed

    方法:利用自製的傳感針,在體監測8隻山羊的大腸俞、肝俞和關元俞及其對應的非穴位點的鈣離子濃度;並監測肝俞和后三里及其對應非穴位點的氧分壓。
  6. 2. with increasing concentrations of pyr and nap, a decrease in the number and length of roots were observed

    Nap在中濃度組對幼苗根的生長就產生了抑制作用,而pyr則沒有影響。
  7. Apart from the concentrations and chemical properties of the pollutants, the person s age and general state of health, the duration of exposure, factors such as the weather condition and the distance from the emission sources also affect the nature and extent of the health effects observed
