    銀合歡於恆春地區嚴重蔓延,根據林試所恆春研究中心以嘉磷塞注射樹幹方式獲致良好控制效果,本研究進ㄧ步進行嘉磷塞不同濃度處理效果,及嘉磷塞施用後在樹體及土壤之殘毒監測。研究結果顯示不同濃度嘉磷塞處理下,施藥後ㄧ週於注射孔上方約350 cm之銀合歡小葉快速凋萎。整株植株於處理藥劑後其傷害在施藥後1個月最為嚴重,雖然施藥後2個月受害植株開始萌新芽,但新芽多呈褐化畸形。檢測藥劑殘留量顯示藥劑隨時間逐漸消褪,施藥後五個月藥劑殘留量降至施用量的10%,根部則於施藥後三個月偵測出較高殘留量但亦隨時間迅速下降。進ㄧ步以HPLC及放射性同位素分析藥劑流向,研究結果顯示施藥初期藥劑可能於木質部藉擴散方式向周圍轉運,其中大量藥劑累積於兩注射孔中間之韌皮部,並隨時間進行雙向運輸,推測韌皮部為藥劑轉運之主要通道。施藥後45天發現注射孔上方韌皮部有較高之藥劑殘留,於60天後各部位藥劑濃度均隨時間下降,根據放射性同位素活性偵測亦顯示相似變化,然而60天後注射孔上方之放射活性降低而下方放射活性反而增加。探究原因推測由於苗木施藥後於注射孔下方逐漸萌新芽,可能因同化物質source-sink關係改變,使嘉磷塞及其代謝物經由韌皮部重新分配至植體下方,而配合TLC及放射活性分析可以確認此時嘉磷塞除了降解為少部分已知的AMPA、及較多量之sarcosine之外,尚有大量之未知代謝物。Leucaena leucocephala, an exotic species widely spread in Hengchun peninsula, Taiwan, was controlled efficiently by a herbicide of glyphosate . In this study, effects of glyphosate with three different concentrations but an equal amount of dosage were compared, and changes of glyphosate residues in plants and soil environment were also detected. Experimental results showed that rapid wilting of leaflets at height of 350 cm away from glyphosate injection site on basal trunk one week after treatment was found, and serious injury of whole plant occurred within one month. Although newly-formed buds appeared on basal trunk with time, subsequent bud growth was retarded and leaflets were small, chlorotic and deformed. Glyphosate detection showed that residues in plants dissipated rapidly in 3 months, and decreased to 10% 5 months after treatment. Further experiment to study glyphosate translocation in L. leucocephala with HPLC and 14C-glyphosate radioactivity assessment, suggested that most glyphosate residues in xylem likely diffused to surrounding tissues initially, and then temporarily accumulated in phloem located between two injection sites before translocating out subsequently. Therefore, it is implicated that phloem is a primary translocation channel of glyphosate. Glyphosate dissipation analysis revealed that more residues were found in upper phloem 45 days after treatment (DAT) and decreased significantly thereafter. Althrough glyphosate in whole plant including upper, middle and lower parts, was decreased after 45 DAT, radioactivities of 14C-glyphosate and its derivatives in lower phloem accumulated dramatically 90 DAT. The redistribution of 14C-glyphosate and its metabolites to lower phloem of basal trunk is partially resulted from an alteration of source-sink relationship of photosynthate due to the formation of newly-formed leaflets on basal trunk.目次 頁次 中文摘要 ……………………………………………………………i 英文摘要 ……………………………………………………………ii 目次 …………………………………………………………………iii 圖目次 ………………………………………………………………iv 第一章 緒言…………………………………………………………1 第二章 前人研究……………………………………………………4 第三章 材料與方法……………………………………………… 17 第四章 結果與討論…………………………………………………28 ㄧ、嘉磷塞控制銀合歡之效果…………………………… 28 二、嘉磷塞於環境中之消褪……………………………… 35 三、嘉磷塞之轉運研究…………………………………… 52 四、嘉磷塞代謝物變化…………………………………… 60 五、藥劑殘留重新分配之可能原因……………………… 64 六、結論…………………………………………………… 69 參考文獻………………………………………………………… 70 附錄……………………………………………………………… 7

    生物技術中應用於作物改良者,分子標誌因子(molecular markers)是較為實際與典型的例子之一。在蔬菜作物中,番茄分子標誌因子之研究堪稱典範。在可資利用之分子標誌因子來源中,隨著分子生物技術之進步,已由早期利用蛋白質、酵素膠體電泳法,配合酵素活性染色的同功異構酶(isozyme)分析,進而利用DNA限制內切酶酶譜多形性(Restriction fragment length polymorphisms;RFLPs),至新近應用聚合酶連鎖反應(Polymerase chain reaction;PCR)所產生的聚合酶逢機擴增多形性DNA(Random amplified polymorphic DNA;RAPD)為標誌因子。這三種方法中,同功異構酶之發展最早,在蔬菜作物之報告亦不勝枚舉,其法之優點為分析方法簡單,而缺點則為可當分子標誌因子之因子座有限;而RFLP 分析法係利用DNA 限制內切酶辨識特殊鹽基系列之特性,若不同個體之DNA序列不同時,限制酶切割後所產生片段之大小、數目亦因此而有不同,經與該段序列有某種程度相似性之探針複合(hybridization )檢定,所產生不同之圖譜做為標誌因子,此方法之優點為所產生之因子數遍佈整個基因組,缺點為分析所用之方法較耗人力與時間;目前蔬菜作物除番茄已建立良好之RFLP分子標誌圖譜外,馬鈴薯、萵苣、甜菜、豌豆及一些十字花科蕓苔屬類蔬菜亦已有了報告。而有關利用聚合醃連鎖反應,其逢機擴增DNA片段大小不同為標誌因子之方法,其優點為簡單、快速,缺點為大部分RAPD分子標誌因子為顯性,無由分辨異型合子,且有關RAPD在作物上利用之報告目前十分有限,在發展上是否有其他受限之處有待進一步之探討。此外分子標誌因子之利用亦已由早期用以篩選一些主效因子,如抗病、抗蟲、雄不稔性等因子之選拔,進一步用來標定數量性狀之選拔。 The utilization of molecular markers for crop improvement is believed to be one of the benefits from biotechnology. Presently, at least three types of molecular markers such as isozyme, RFLP (Restriction Fragment Length Polymorphism) and RAPD (Random Amplified ploymorphic DNA) derived from AP-PCR (Arbitrary Primer Polymerase Chain Reaction) are available. Among these, isozyme markers were studied the earliest and a lot of research has been conducted. The advantages of isozyme as molecular marker are its simplicity and ease for analysis. However, the limitation on the number of polymorphic loci is the major drawback in its application. RFLP markers analyzed on the DNA level are believed to be very promising because the markers obtained can be saturated all over the linkage map. Nevertheless, the profoundity and complexity of its methodologies have slowed down its utilization. Among the vegetable crop species, RFLP markers and linkage map have been well established in tomato. Other crops such as potato, lettuce, sugar beet, pea and Brassica species also have several studies on the RFLP markers. RAPD derived from AP-PCR was most recently reported. The advantages of RAPD markers are its rapidity and efficiency during the analyzing processes. However, the predominance with dominant gene action on RAPD markers will require twice as many markers as those of codominant markers to distinguish a heterozygote. Since only very limited studies are avaliable now on RAPD in crop species, whether there is any other limitation requires further investigation. Furthermore, gene mapping is no longer limited to those of major qualitative genes such as disease, insect resistance, and male sterility, etc. Selection for quantitative traits have become possible through the aid of molecular markers

    有關同功異構酶的分析與利用目前在各主要作物已有不少之報告,然甘藷在這方面的研究仍極為有限。此與甘藷本身遺傳背景之複雜性及組織成份物質對酵素活性分析之干擾有或多或少之關係。近年來雖有一些新型分子標誌因子分析法,如核酸限制內切酶多形性分析及利用聚合醃連鎖反應所導來之逢機擴增多形性DNA等,然同功異構酶分析法仍不失為較簡單、易學、經濟且快速之分析法,其分析所需之組織量少,且幾乎各類型之組織均可利用來作分析,在應用上仍有其優點。本報告即針對目前有關甘藷同功異構酶已見報之資訊,及本研究小組近年來在甘藷同功異構酶分析與利用上之探討作一綜合性之報告。所討論之酵素主要以具多形性酶譜之酵素如酒精去氫酶、β一澱粉酶、磷酸化酶、過氧化酶、黃遞酶、酯酶、磷酸葡糖變位酶、蘋果酸去氫酶、蘋果酸酵素、磷酸葡糖異構酶、6-磷酸葡糖去氫酶、穀草酸轉氨酶、莽草酸去氫酶、甲基萘酶、還原酶及胰蛋白抑制酶等。 Studies on the analysis and utilization of isozyme patterns in sweet potato [Iponioca baiatas (L.)Lam.] are very limited in comparison with those of the major crop species. This might be due to the relative complexity of the sweet potato genomes and the existence of certain chemical components in tissue extracts tending to interfere the enzyme staining activity. In spite of the recent development of DNA molecular markers derived from restriction fragment length polymorphisms and random amplified polymorphic DNA derived from arbitrarily primed polymerase chain reaction, the isozyme approach is still the easiest and most economic and rapid method available. In addition, it also has the advantage of the small amount of tissue needed for the assay and no restriction to tissue type. In this communication, the current progress in isozyme analysis and utilization of sweet potato are reviewed. Emphases are laid on those polymorphic enzymes such as alcohol dehydrogenase, β-amylase, diaphorase, esterase, glutamatic oxaloacetate transaminase, malate dehydrogenase, malic enzyme, menadione reductase, peroxidase, phosphoglucomutase, 6-phosphogluconate dehydrogenase, phosphoglucose isomerase, phosphorylase, shikimate dehydrogenase, and trypsin inhibitor
