簡介:山東農(nóng)業(yè)大學(xué)碩士學(xué)位論文科技文獻對園藝科技發(fā)展的作用研究姓名李燕申請學(xué)位級別碩士專業(yè)農(nóng)業(yè)推廣指導(dǎo)教師毛志泉20051210山東農(nóng)業(yè)大學(xué)碩士專業(yè)學(xué)位論史摘要在現(xiàn)代科學(xué)研究中,科研人員、試驗手段、科技文獻是缺一不可的三大要素,而科技文獻的利用貫穿于科學(xué)研究整個過程,并發(fā)揮著重要的作用。目前,科技文獻對醫(yī)學(xué)、水利、森林培育等方面的發(fā)展作用的研究較多,但對園藝學(xué)的發(fā)展作用研究較少。為此,本研究調(diào)查了當前科技文獻的分布、查閱情況及園藝學(xué)發(fā)展水平,目的是通過了解科技文獻的利用情況及園藝學(xué)科的發(fā)展狀況,分析科技文獻對園藝科技發(fā)展的作用,更好地促進園藝科技的發(fā)展。主要研究結(jié)果如下1從園藝學(xué)院的師生查閱類別來看,查閱農(nóng)業(yè)科學(xué)期刊次數(shù)最多;對利用率最高的農(nóng)業(yè)科學(xué)類期刊分布狀況進一步統(tǒng)計,發(fā)現(xiàn)農(nóng)業(yè)科學(xué)期刊利用類別主要分布在學(xué)報、綜合類農(nóng)業(yè)科學(xué)、農(nóng)業(yè)基礎(chǔ)科學(xué)等期刊上。2對科技文獻的利用情況進行了調(diào)查研究,統(tǒng)計表明,隨著時代的發(fā)展,科研人員對科技文獻的利用在數(shù)量和質(zhì)量上都呈增長趨勢園藝學(xué)院本科生主要是利用圖書期刊查閱文獻,而研究生與科研人員主要是利用電子期刊。在電子期刊中,全文數(shù)據(jù)庫利用率最高。3對科技文獻與園藝科技的發(fā)展作用進行了相關(guān)性分析。研究表明引文量、科技檔案的查閱量與論文的發(fā)表相關(guān)系數(shù)均達到了O96以上相關(guān)性較大,也就是說,科技文獻直接促進了專著與論文的寫作;科研經(jīng)費逐年增加,與引文量相關(guān)系數(shù)為098,相關(guān)性較大,進而促進了科研水平的提高;而引文量、科技檔案的查閱量與獲獎成果數(shù)量相關(guān)系數(shù)為一090左右,相關(guān)性不大。4研究結(jié)果表明隨著科研工作的進一步開展,科研人員對科技文獻的利用數(shù)量不斷增多,利用質(zhì)量也不斷提高,科技文獻對園藝科技整體水平的發(fā)展有明顯的促進作用。5存在問題目前,我國科研人員利用科技文獻的能力和狀況不容樂觀。主要表現(xiàn)為不善于全面利用各類文獻、不善于利用各種檢索工具

簡介:學(xué)校代碼10225學(xué)號S13146學(xué)位論文幾種園藝植物病毒檢測技術(shù)研究指導(dǎo)教師姓名申請學(xué)位級別論文提交日期授予學(xué)位單位付耕云楊洪一副教授東北林業(yè)大學(xué)碩士學(xué)科專業(yè)微生物學(xué)2013年4月論文答辯日期2013年6月東北林業(yè)大學(xué)授予學(xué)位日期2013年6月答辯委員會主席論文評閱人聾夕參妊素大學(xué)摘要摘要園藝植物是一類供人類食用或觀賞的植物。園藝植物病毒是嚴重影響園藝生產(chǎn)的重要因素之一。為了進一步控制病毒危害,本研究旨在建立從園藝植物辣椒、蘋果、櫻桃中分離DSRNA或總RNA的方法,并應(yīng)用瓊脂糖凝膠電泳、RT.PCR技術(shù)、免疫捕獲PCR技術(shù)等方法對分離的核酸進行鑒定,從而建立可有效檢測病毒的技術(shù)體系。此外,還分別針對不同試材如葉片、辣椒制品、種子中的病毒進行了檢測,并對辣椒病毒的滅活進行了初步探索。1、對辣椒病毒DSRNA的提取進行優(yōu)化,建立了成熟的提取辣椒病毒DSRNA的技術(shù)體系,通過瓊脂糖凝膠電泳獲得了特異的DSRNA片段。分別采用雙酶解方法和DNA凝膠回收試劑盒對DSRNA譜帶進行純化,經(jīng)比較采用DNA凝膠回收試劑盒回收DSRNA譜帶比雙酶解法更好,可有效獲得單一的DSRNA片段。2、利用改進的CTAB法提取辣椒制品中的總RNA,并建立RTPCR技術(shù)檢測辣椒輕斑駁病毒的技術(shù)體系。對辣椒制品辣椒醬、咸菜、辣椒粉中的辣椒輕斑駁病毒進行檢測,在一些辣椒制品中檢測到了辣椒輕斑駁病毒,說明辣椒輕斑駁病毒較難以被破壞。將辣椒制品中的辣椒輕斑駁病毒經(jīng)摩擦接種轉(zhuǎn)移至煙草,可在煙草上顯示明顯病毒侵染癥狀,并進一步經(jīng)RTPCR證實。從而說明辣椒制品中含有的辣椒輕斑駁病毒可有效傳播及增殖。已有報道顯示辣椒輕斑駁病毒可能侵染人體并引起一系列的反應(yīng),因而食品中的辣椒輕斑駁病毒也需要被密切關(guān)注。3、利用RT.PCR技術(shù),對北京、沈陽、哈爾濱三地的商品辣椒種子中的辣椒輕斑駁病毒的帶毒率進行了分析,結(jié)果顯示40種種子中,共有15種種子被辣椒輕斑駁病毒感染,說明當前該病毒的危害及傳播已較嚴重。4、利用高溫干熱處理對辣椒種子內(nèi)的辣椒輕斑駁病毒進行了滅活處理,結(jié)果顯示,70℃處理未見明顯滅活效果,75℃處理48H可滅活70%的病毒,且對種子的發(fā)芽率影響相對較小。該技術(shù)體系具有一定的應(yīng)用潛力。5、利用RT.PCR技術(shù)對蘋果病毒進行了檢測,建立了對3種蘋果病毒的檢測技術(shù)體系。對一些蘋果、毛櫻桃、杏樣本進行了檢測,結(jié)果顯示不同樣本中3種病毒侵染率皆較高,且存在較多混合侵染的現(xiàn)象。6、基于RT.PCR技術(shù)的假陰性及假陽性、血清學(xué)技術(shù)的靈敏性差問題,探索建立病毒的IC.RTPCR檢測技術(shù)體系。分別以辣椒輕斑駁病毒和蘋果莖痘病毒為試材,利用病毒特異抗血清包被薄壁管,捕捉感病葉片粗汁液中的病毒粒子,之后運用RT.PCR方法對捕捉的病毒進行特異性擴增,最終建立了可穩(wěn)定檢測辣椒輕斑駁病毒和蘋果莖痘病毒的技術(shù)體系。關(guān)鍵詞DSRNA;RT.PCR;免疫捕捉;辣椒輕斑駁病毒;蘋果病毒
