摘要或動機

我們的研究報告,是對校園中所種植的各種變葉木所做的一個研究,經過一連串的實驗證明後,我們確信花青素對變葉木的光合作用會有所影響。接著,我們測定出未氧化的植物色素與已氧化的植物色素吸光能力有很大的差異,我們假設花青素可以吸收某些特定波長的光以防止植物色素的氧化程度過強,實驗後證明我們的假設是正確的。另一方面,我們預期花青素具有保溫的機制,故設計了一個在低溫下花青素可保溫的實驗以證明之,結果和我們的假設相符合。我們預期花青素可利用保溫的特性降低植物因低溫所造成的傷害,減少農業上的損失。This study is about the Codiaeum variegatum which is grown on campus. After a series of experiments, it was proved that “anthocyanin” has a significant influence on the photosynthesis processing in Codiaeum variegatum. A great difference in the pigment of plant’s light-absorbing ability between the oxidized plants and the non-oxidized ones was also found in the experiments. Therefore, it was supposed that anthocyanin could absorb some special range of wavelength to avoid the pigment of plant to over-oxidize. The result of this experiment is in accordance with our supposition. In addition, we anticipated that anthocyanin has the ability to stay warm. By a designed experiment we successfully found that the result is exactly the same as our assumption. According to the findings of our study, we expect the characteristic -- ”staying warm” of anthocyanin could be applicable to decrease the harm to plants caused by the low temperature, and thereby to reduce the loss in agriculture.
