蜈蚣草是世界上首次報道的一種砷超富集植物，同時也是鈣質土壤的指示植物。 -
Abstract : 145 samples of eight plants were collected from lanmuchang and yangjiawan and quantitative analyses were made of the ore - forming elements in the plant ashes. considering the three principles of the plant indicator for mineral exploration, namely certainty, sensitivity and feasibility, this paper evaluates comprehensively the indicating functions of the eight plants, on the basis of some quantitative indexes such as the relation coefficient between plant ash and ore - forming element, concentration coefficient, etc. it also discusses the relationships between the anomaly of plant ashes and the fault zone, alteration zone mineralization zone and orebody, showing the significance of these plants to the prospecting
文摘:在濫木廠和楊家灣鉈（汞）礦床（點）對芒箕、南燭、榔榆、大金發蘚、蜈蚣草、石松、黃花草、醉魚草等8種植物取樣145件，在提出確定找礦有效指示植物三原則（確定性，敏感性，可行性）的基礎上，依據植物灰分與底質成礦元素相關系數、植物灰分富集系數和襯度系數，較全面地分析和評價了8種植物的找礦功能；討論了其異常的分佈與斷裂帶、蝕變帶、礦化帶以及工業礦化（礦體）之間的關系，並指出了其找礦意義。 -
In spac, it is the plant that should be optimum indicator for irrigation control, because the soil factor and air factor, which control the balance of water in crops, can but be integrated by plant
而在土壤?植物?大氣連續體（簡稱spac ）中，植物才應該是是否需要灌溉的最優指示物，因為只有它們才能把控制植物水分平衡的土壤因子和大氣因子綜合起來。 -
The physiological reaction of c. junos under iron stress in field experiments, c. junos manifested itself as tolerant to iron stress. no chlorosis symptom was not found in its leaves when it was grown in a soil with ph 7. 8. in contrast, severe chlorosis was found in the control plant p. trifoliata grown under the same soil conditions, and leaf chlorophyll content as an indicator for the degree of fe deficiency in p. trifoliata was much lower than in c. junos
主要的研究結果如下： 1 ：鐵脅迫下香橙的生理反應研究香橙在田間實驗中表現耐缺鐵，在ph7 . 8的土壤中生長正常，葉片無任何缺鐵癥狀；但對照植物枳在同樣土壤條件下卻表現出明顯的缺鐵癥狀，作為缺鐵程度指標的葉片葉綠素含量極顯著低於香橙。 -
The pollution effects of the plant leaves treated with acid material can be detected quantitatively by means of df. the technique would likely to be applied as a practiced field application with easier operation than chlorophyll fluorescence technique. thus, we conclude that delayed fluorescence is an excellent indicator for evaluating the extent of environment stress on plant
因此，利用植物的光誘導延遲熒光在一定程度上可以檢測出雨水和空氣中酸性物質對植物葉片的脅迫效應，該方法比常規的理化手段更接近於環境的真實狀況，而且比葉綠素熒光技術便於操作。 -
Although the melting in itself is a troubling indicator of a warming planet, the bigger concern is invisible : the lakes are emitting huge amounts of methane as ancient plant and animal remains thaw and decompose underground
盡管它們的溶化是全球變暖的標志，但最大的擔憂是一種無形的危險物質：隨著地下遠古動植物解凍並腐壞，這些湖會噴出大量甲烷。 -
Compared with common methods for measuring the photosynthesis rate based on consumption of co2, the technique in this thesis can be used to quantify the plant photosynthesis capability with less interferences of the environment. we thus conclude that df is an excellent indicator for evaluating plant photosynthesis ability under its biological status
研究結果表明:植物葉片延遲熒光強度和現有的便攜式光合速率測定儀在實驗室條件下測得的光合速率具有很好的相關性，能較真實的反映植物在所處生理條件下的光合能力。
