GOOGLE翻譯的就不要了!提前謝謝各位大俠啊,小弟有禮啦! 翻譯內(nèi)容:【在一定Mn濃度梯度處理下(0、200、500、2000、5000和10000 μmol•L-1),超積累植物——酸模葉蓼(Polygonum lapathifolium)不同組織器官的傅里葉變換紅外光譜(FTIR)圖譜發(fā)生了變化。其中,莖組織在3420和2920 cm-1處錳處理濃度大于200μ mol•L-1后,峰高先上升后下降,反映了有機(jī)物運(yùn)輸受阻情況的變化,即酸模葉蓼在低濃度Mn2+刺激下會產(chǎn)生大量有機(jī)物作為滲透調(diào)節(jié)物質(zhì)來增強(qiáng)其耐錳性,高濃度Mn2+則抑制了有機(jī)物的分泌和運(yùn)輸;根和葉組織分別在2920和1630 cm-1處處表現(xiàn)不同變化趨勢,但都反映了一個(gè)變化規(guī)律即低濃度Mn2+處理下酸模葉蓼分泌的有機(jī)酸不斷螯合Mn2+,隨著Mn毒害的加重,其羧酸螯合力變?nèi)酰桓M織、莖組織、葉組織1060 cm-1處呈現(xiàn)差異性變化,但都與其膜脂過氧化有關(guān);以上說明,利用FTIR研究重金屬超積累植物化學(xué)組分具有應(yīng)用價(jià)值! |

| Mn concentration gradient in certain treatments (0,200,500,2000,5000 and 10000 μmol • L-1), hyperaccumulators - Rumex Knotweed (Polygonum lapathifolium) different organs of the Fourier transform infrared spectroscopy (FTIR ) map has changed. Among them, the stem tissue in 3420 and 2920 cm-1 處 manganese concentrations greater than 200μ mol • L-1, the peak height increased and then decreased, reflecting changes in the situation of organic matter transport is blocked, that leaves Polygonaceae Rumex Mn2 + stimulation at low concentrations likely to result in a large number of organic compounds as osmolytes to enhance their resistance to manganese, high concentrations of Mn2 + is inhibited organic secretion and transport; roots and leaves at 2920 and 1630 cm-1 have demonstrated different trends, but reflected A variation of the low concentration of Mn2 + to the next dock Knotweed chelating organic acids secreted continuously Mn2 +, with Mn toxicity increased, the carboxylic acid chelating weak force; root tissue, stem tissue, leaf tissue exhibits a 1060 cm-1 differences in change, but all its lipid peroxidation; described above, the use of heavy metal hyperaccumulator FTIR chemical components with value |
