The results showed that the nearer the relationship of the species, the more similar the zymograms. the zymograms difference between species in different genes is more obvious than ones in the same one. in addition, there is a certain difference between the zymograms of different strains of the same species from different ascocarps and places
結果表明，親緣關系愈近的菌株其酶譜的相似性愈大，屬間差異明顯大於種間差異，同菌種的酶譜可因寄主、產地不同等而存一定差異。Based on the field investigations and laboratory examinations, a study of the population of the epiphytic dolichomitriopsis diversformis ( mitt. ) nog. in fanjing mountain reveals that its habitats are different among different host trees, but that there lies the common habitat characteristics of not more than 2m height from the bottoms of host trees trunks, less light, high relative humidity, slow wind speed, slow evaporation speed and long time of remaining humid in middle - lower tree bark ; that it is one dioecious moss species, the morphology is remarkably different between its perichaetium and perigonium, the number of its perichaetia is much more than that of its perigonia, its perigonium is difficult to find out, its sporophyte is upright, its seta is long and thin, its capsule is regular long oval and its calyptra is cucullate
摘要通過野外調查和室內觀測對貴州省梵凈山樹附生尖葉擬船葉蘚種群的研究表明，其生境因其所附生的樹種不同而有所不同，但具有共同特點：附生在樹干下部距地面2m高的范圍之內，光照弱、濕度大、風速小、蒸發量小、中下部樹皮保持濕潤的持續時間長；其為雌雄異株蘚種，雌、雄器苞形態差異明顯，雌器苞數量多，雄器苞數量少並且難于發現，孢子體直立，蒴柄細長，孢蒴規則長卵形，蒴帽兜形。Hemagglutinins inhibition ( hi ) testes showed that there were obvious variations among the isolates from different geographical areas. this result explained why the protection rates of current vaccine were different around the country. dna sequence analysis of h9 hemagglutinin genes showed that these viruses were closely related and possibly came from one source
且在同一地域內，不同的異變體之間的差異較小，隨著時間的推移，其變異並不明顯；但在不同的區域內分離的毒株之間變異較為突出，這表明中國大陸h9n2亞型禽流感病毒不同分離株抗原性是與地域的改變而發生較為明顯的變異。Sequence comparison indicated that the nucleotide homologies between the ha gene and those from eight other h3 subtype sfv isolates from china are over 95 %, and nucleotide identities between h3 sfv isolates in china and a typical h3 subtype avian influenza virus ( aiv ) strain dkuk1 - 63 are 95 % to 100 %. these might tell us that the ha gene of all h3 subtype sives isolated in china was originally from aiv although the vaccine based on ha do not protect against different subtype of influenza virus, it can provide favorable resistance to infection with antigenic variants within a subtype
通過與其它7株國內siv分離株和6株genebank中的h3流感病毒ha序列比較分析，結果表明分離自我國不同地區的8株h3siv核苷酸序列同源性均在95 %以上，且與禽流感病毒（ aiv ）經典代表株dkuk - 63序列同源性在95 - 100 %之間，證實我國h3sivha基因來源於禽的流感病毒。Fifty nine accessions of soybean [ glycine max ( l. ) merr. ] of 301 ones from huanghuaihai and middle - lower changjiang valleys were tested at seedling stage in two years for their drought tolerance by using the mean membership index value averaged over those of plant height, leaf number, root dry weight, stem and leaf dry weight. 4 tolerant accessions ( rank 1 ) and 2 sensitive ones ( rank 5 ) were identified
摘要從301份大豆品種中按根系類型選取黃淮海和長江中下游地區代表性材料59份，在苗期乾旱脅迫和非脅迫條件下對地上部和地下部性狀進行2年重復鑒定，發現材料間性狀隸屬函數值具有豐富遺傳變異，以株高、葉齡、根干重和莖葉干重隸屬函數的算術平均數為抗旱綜合指標，從中篩選出漢中八月黃、晉豆14 、科豐1號、圓黑豆等強耐旱型（ 1級）材料和臨河大粉青、寧海晚黃豆等乾旱敏感型（ 5級）材料。Sequence analysis of 16s rdna and its from isolates of acinetobacter spp. ( strain eva10, eva11, eva12, eva13, eva14 ) revealed some discrepancy with result of phenotypic characteristics so that the determination of isolates at species level and phylogenetic relationship of acinetobacter spp. still would depend on further study
Acinetobactsr屬分離菌株eva10 ， evall ， eva12 ， eva13 ， eva14的表型特性， 165rdna和廠s的分析結果存在一些矛盾，確定種水平分類的地位和該屬各個種之間的系統發育關系仍需進一步研究。Biodiversity exists among am fungi and is influenced by numerous factors including soil properties and plant species. if am fungi are to be used in sustainable agricultural systems it is necessary to study native am fungi in the target areas and then select efficient isolates that can be applied as inocula in the field to improve crop growth. the objectives of this study were to investigate the germplasm of am fungi, to understand the distribution pattern of am fungi in different ecological conditions such as area, soil factor and host plant, to select isolates effective in nutrient acquisition by the host plant sweet potato, to test their effectiveness under field conditions, and to monitor amf after their introduction into the field

進化分析表明，我國內地分離株皆由內地早期分離株進化而來，各個毒株之間關系非常密切，進化相對緩慢。Both absolute difference and relative difference among per capita gdps of 14 cities ( prefectures ) increased year by year since 1990 - the absolute difference increased linearly - - and this increased tendency would n ' t change in short period. by counting the discrete and ratio between per capita gdp of every city ( prefectures ) and that of the total province, the relative development speed of every region and the industrial structure of every region, i think that the characteristic of the spatial structure of regional economic difference in hunan is that the area along the beijing - guangzhou railway line in the east of hunan developed fast, while the vast area in the west of hunan developed slowly, so the regional difference increased constantly. on the difference background between the east and the west of hunan, there is the difference between central region and fringe region, for one thing it shows ring difference, namely chang - zhu - tan internal ring, surrounding chang - zhu - tan medium ring, the outermost external ring, the most underdeveloped counties lie on the fringe and mountain regions in the west, south and east of hunan, for another it displays that the peripheral regions of 13 prefectural cities are more developed than the other
文章還建立了反映基礎設施水平、經濟發展水平、社會發展水平的23個主要指標構成的湖南省區域差異衡量指標體系，在此基礎上，藉助spss統計分析軟體，運用主成分分析法，對湖南省14個市州經濟發展綜合水平的差異狀況進行了研究，結果表明：長沙市的經濟發展綜合水平在14個市州中遙遙領先，反映了湖南省經濟發展空間結構的「單極主導」特徵；通過計算人均gdp的標準差和標準差系數，研究區域經濟差異的總體水平及區域經濟不平衡發展的演變趨勢，發現90年代以來湖南省各市州人均gdp的絕對差異和相對差異都在逐年擴大，其中絕對差異隨年份直線上升，且這種差異擴大的趨勢在短期內難以改變；通過計算各市州人均gdp與全省人均gdp的離差和比率、各市州發展速度的差異及產業結構的差異，認為湖南省區域經濟差異的空間特徵是：湘東京廣沿線地區基礎較好，發展較快，湘西地區發展緩慢，地區差異不斷擴大；通過以縣為對象的差異研究發現在湘東湘西差異的大背景上還有核心區與邊緣區的差異，它一方面表現為長株潭內層、圍繞長株潭的中層、更遠的外層的圈層差異特徵，最落後的縣分佈於湘西、湘南、湘The rest mutations in pp38 and pp24 are at random. sequence analysis also shows the first 195 nuclear acids of pp38 and pp24 are the same except for the 81 site ( g / c ), but this mutation does not cause the change of amino acid. we regard this as a genetic marker connecting with geography in the evolution of mdv but not related to isolated time and pathotype of different strain of mdv i
對pp24基因和pp38基因進行同源性比較分析的結果表明，絕大多數毒株二者的前195個核苷酸完全一致，不同毒株間的第81位核苷酸的差異（ g / c ）並不引起編碼的氨基酸變化，僅僅與地域分佈有關，這很可能是mdv在長期病毒衍化過程中形成的地域性遺傳標志，而與病毒的分離年代及mdv的致病型等因素無關。Because of this, we should put more attention on the treatment - time, if we want to use the half of the lethal salt concentration to judge the capacity of plant fastness to salt. as the salt content increased, the sodium and chloride content of plant increased also. after 36 - day treatment, the plants grew under 50 ~ 100 mmol. l - 1 salt levels had the most amount of salt ions
Nacl環境下，植株體內鹽分離子na ~ + 、 cl ~ -含量均隨著鹽分水平的升高而升高；但隨著處理時間的延長，根部na ~ + 、 cl ~ -含量表現為不斷地顯著增長，而地上部則表現為先增長後下降的趨勢；經過36天的鹽分處理，地上部鹽分離子的最大無差異單株積累量分佈在50 100mmol ? l ~ （ - 1 ）左右的鹽分環境下。分享友人
