南國田字草的型態生理與睡眠運動之研究
Marsilea quadrifolia, an aquatic perennial rhizomatous fern, is widespread on wetlands in Taiwan. A normal fern frond has the clusters of spore capsules on the back, yet Marsilea quadrifolia reproduces clusters at petiole base from sporocarps which are axillary, pedicellate, ovate and hairy; both microsporangia and megasporangia can be found in sporocarps. It is highly polymorphic. The sterile fronds are erect when growing in mud, and floating in water, and they produce leaflets in the shape of four-leaf clovers. Mature leaves are divided into water leaves and terrestrial leaves according to living environments. Water leaves are divided into submerged leaves, floating leaves, and emergent leaves. These four kinds of leaves have obvious differences in stoma density. The submerged leaves have the least starch which means they have the minimum photosynthetic efficiency. The flexible leafstalks allow the plants to adapt to small changes in water level, while keeping their leaves on the water surface to access light and carbon dioxide. Thus, heterophylly may be seen as an adaptive mechanism which is sensitive to some environmental parameters and that responds accordingly to maximize the capability for survival. The terrestrial leaves have periodic sleep movement according to the alternate changes of day and night. The biggest opening angle is related to a definite leaf closing time cycle. Light interference during the dark period, continuous lighting, or the reversing of day and night all interfere the opening time and speed of them.南國田字草是一種浮葉性、多年生水生蕨類，匍匐莖細長橫臥在水中泥土或濕地裡，葉四枚對生於葉柄頂端，依生長環境不同，可分為水生葉及陸生葉，水生葉又分沉水葉、浮水葉及挺水葉三種。孢子囊群聚集特化成堅硬的孢子囊果，長於葉柄基部，孢子有大、小孢子兩型。四種異型葉在內部構造、氣孔分布密度上皆有相當的差異，以適應環境的變化，葉片澱粉含量以沉水葉最少。南國田字草陸生葉隨著晝夜交替，具有週期性的睡眠運動，每天葉片開啟的最大角度和閉合時間有一定的時間範圍。黑暗期受光照干擾或連續照光、日夜顛倒，皆影響葉片的開閉時間與速率。
蓮花自潔效應之成因機制
奈米科技是二十世紀末、二十一世紀初新興的科學技術，由於它是在1~100 nm（n = 10-9）的尺度內改造原子及分子排列，創造新物質【1】，將顛覆傳統改造物性，被預言將帶來人類的第四波工業革命，對物理、電子、光電、化工、材料、生醫、機電各領域帶來巨大衝擊。『蓮』是世界上最早的被子植物之一，在一億四千萬年前就生長在地球上，蓮的分布甚廣，從印度、中國、日本、北美到西伯利亞到處都有蓮的蹤跡。蓮的生命力強，很能適應環境，美國加州大學曾試驗培植古代蓮子，經過1300 年的沉睡，古代蓮子仍然正常發芽【2】。台灣的蓮花是十七世紀的移民，自中國帶來種植的。『奈米科技』和『蓮』這兩個不同年代的產物名詞如何連結在一起，他們怎樣相互依存；這正是本文討論的重點，也是了解『奈米科學』很好的例子。本文藉出汙泥而不染，闡述蓮花的自潔（self-cleaning）效應。一般在奈米技術中，簡稱『蓮花效應』【3】，包含清潔機制、成因；使用觀察紀錄自潔狀況情形，幫助對蓮花自潔過程的掌握。期望能對具有蓮花效應的奈米結構提供良好的意見。本研究的結果發現，蓮花效應強的植物，幾乎具有高抗水性。而抗水性是來自奈米結構和表層蠟質，這兩個特質也是蓮葉、芋頭葉等高蓮花效應的植物所具備的，所以我們推論:奈米結構和表層蠟質越發達，抗水性越好，則植物葉面的蓮花效應越強。Nano technology is one of the most advanced technologies now. Since it will alter and rearrange the fundamental structures of atoms and particles within the space of 1~100 nm (n=10-9) the coming industrial revolution depends on it. Nano technology will pose dramatic impact upon a variety of specific fields including physics, electronics, photon electronics, chemical industries and so on. Lotus is one of the most primitive covered-seed plants. It has existed since 140 million years ago and has spread in wide areas. The University of California made lotus seeds that have been frozen for 1300 years sprouted. The Taiwanese lotus seeds were transported from China in the 1600s. The researchers are to probe into the relationship between the nature of lotus and nanotechnology to understand the potential significance of this newly developed technology. The researcher employed the direct observation and tape recording to collect the objective data of the individual growth steps of lotus to analyze the self-cleaning effect of the lotus. In the conclusive part, the application of the Lotus Effect and the creative technology will be discussed and analyzed with the hope to prescribe both a conclusive experimental principles and a further direction for the manufacturing systems related to the developing Lotus Effect. The researchers of the study found that those plants, which have high quality of Lotus Effect, are given the nature of resisting water, which is the consequence of two features namely, the nano-structures and the surface wax. And the leaves of lotus, potato all have these two features. Therefore, it is inferred that the more efficient mechanism of the nano-structure and surface wax and Lotus Effects the plants are, the more effects of the water-resistance function will the plants achieve.
短暫高鹽刺激提升番茄果實品質
本研究透過對蕃茄施予短時間的不同高鹽份濃度刺激，觀察植株成長 情形並對果實進行品質測定，本研究對於品質之定義著重於總抗氧化能力、糖度及硬度的檢測。由實驗結果得知Na+、Cl-離子所造成的滲透壓差，確實有助於可溶性固形物及Na+、Cl-離子的累積，對於果實糖度及硬度上皆有顯著變化。但對於如何造成總抗氧化能力值的提升，在未來的研究中會再深入探討。We observe the germination of the tomatoes and assay "the quality" of the fruits in our research by giving plants short-range acridness of different high salinity. In this research, the definition of “quality” emphasizes the anti-oxidized ability, the brix, and the hardness. By the experimental result knew Na+ and Cl- ion creates the osmotic pressure, truly is helpful to the Soluble Solid Content and the Na+ and Cl- ion accumulation. Yet regarding by what the anti-oxidized ability promotes, we will treat in-depth in our intended research.
安培植物假說
在「植物的秘密生命」這本書中提到植物在電場或磁場中會生長的更好,我最近正好學到了電磁場如何產生,以及一些產生電磁場的方法,所以想利用螺形管線圈來產生均勻的電磁場並用安培右手定則來控制磁場產生的方向來了解電磁場在高低室溫下對綠豆生長的影響. 在本實驗中我利用鐵碗纏繞線圈的方式並通入不同的電流大小來改變磁場的強度,所進行研究所得到的結果顯示（1）綠豆只有在適當的電流大小下所產生的電磁場才可以幫助加速綠豆的生長(2)栽培綠豆的環境所架設的電磁場越高,越能持續讓綠豆的生長加速（3）綠豆的加速生長並不需要整天都通電（4）綠豆在N極朝上的磁場中生長的速率較S極朝上的磁場中要快(5)在較低的室溫下,電磁場加速綠豆生長的效應較能顯現 It has been mentioned that the plants will grow faster in the electronic or magnetic field in the book of “the secret life of plants”, I learned about the knowledge and methods of how to produce the electromagnetic field just now, I use the screw wire to produce electromagnetic field and control the direction by the Amplifier’s rule to investigate the growing speed of green beans under electromagnetic field in those different temperature. In this experiment, I use the wire to screwed around the ironed bowl, and make different electric current to generate different strength of electromagnetic field, the results indicate that (1) The faster growing speed will only exist in some strength of electromagnetic field (2) The higher ironed bowls that full of screwed wire will result in the faster growing speed (3) It will not need electromagnetic field all days (4) The green beans will grow fast in those north magnetic pole than those in south magnetic pole (5)The effect of electromagnetic field to increase growing speed will be significant in higher room temperature
光基因新角色-cop8
COP8 is the second unit of COP9 signalsome. In the comparison of BLAST ,we found that\r LLPC14 cDNA and the protein sequence are quit similar to the COP8 of Arabidopsis thaliana\r Therefore, we are interested in the role that COP8 plays in the photomorphogenesis and try to find\r the length of the sequence. So far, no result is obtained about the 3’-RACE, but we’re surprised to\r find that the sequence found in 5’-RACE is shorter than what we’re know, which suggests the RNA\r length of the cDNA used in the RACE combination has decreased.\r Although the final results of the COP8 5’and 3’-RACE haven’t been achieved, it is sure the\r COP8 is highly-conserved in many species. Since the similarity between LLPC14 and the COP8 of\r Arabidopsis thaliana is as high as 90 percent, we used the COP8 of Arabidopsis thaliana to detect the\r COP8 protein in pollen.在過去種綠豆芽的經驗中，不難發現它本身因為環境的不同，而有不同型態白化\r 的現象，例如：黑暗下萌發的豆苗。但尚未深入去理解白化的原因；而在後來的種植\r 經驗上，也發現有許多令自己覺得困惑的相同處。\r 在高二的生命科學第四章中，有提到光照與黑暗生長的植株，在構造比較上有明\r 顯的不同；其中，提及植物的活性組織存在「光敏素」（phytochrome），此色素蛋白的\r 存在於光照後，會引發一連串反應，至此，也稍微了解植物的萌發反應的差別。\r 故藉由個人在中研院植物所的資優生培訓過程，便以此為前題,進一步探究植物基\r 因組COP 8 與白化現象的相關性
Mathematical Analysis of Root Growth in Gamma-irradiated
Root growth is related to the acquisition, distribution, and consumption of water and nutrients of plants. As a vital organ, roots directly take the effect of environmental change and its behavior is closely related to the growth of the whole plant. With such, the importance of root systems has motivated botanists to seek a better understanding of root branching complexity. This complexity, which has been difficult to comprehend using simple Euclidean methods (i.e. lines and circles), is important to the survival of plants, especially when the distribution of resources in the environment is scarce. Mathematical models using fractals and computers can be applied to accurately understand the growth and form complexity of plant root systems. This study was conducted to analyze the root growth of gamma-irradiated cashew and mangosteen using fractals.
