Effects of Truffle Inoculation on the Growth of Cyclobalanopsis glauca (Thunb.) Oerst and the Competivity of Scleroderma areolatum Her. to the Truffle Mycorrhizae
No full text本研究目的為(1)確認青剛櫟(Cyclobalanopsis glauca (Thunb.) Oerst)幼苗接種塊菌(Tuber sp.)對生長效應之影響，(2)龜紋硬皮馬勃(Scleroderma areolatum Her.)對塊菌菌根形成之競爭作用及(3)比較龜紋硬皮馬勃與塊菌在YMT培養基中之競爭狀態。 青剛櫟幼苗經接種台灣塊菌(Tuber formosanum Hu)及印度塊菌(Tuber indicum Cooke & Massee )後，較未接種者可顯著的促進苗高生長、地際直徑、地上部乾重及地下部乾重及地下部之重量生長；且前者之T/R率亦明顯的低於後者。 龜紋硬皮馬勃接種至一年生已形成台灣塊菌及印度塊菌菌根之青剛櫟幼苗二個月後，龜紋硬皮馬勃能形成典型之白色外生菌根，並能自其菌根外形成菌索感染未形成菌根之短根，亦能感染已感染形成塊菌菌根之部分，最後並將其整個包覆。因此接種龜紋硬皮馬勃能減少及抑制台灣塊菌及印度塊菌之菌根形成。青剛櫟塊菌菌根苗接種龜紋硬皮馬勃後二個月，與單獨接種塊菌時類似，同樣可促進青剛櫟幼苗之生長。
由YMT洋菜培養基為介質，進行台灣塊菌與龜紋硬皮馬勃、印度塊菌與龜紋硬皮馬勃等相互間菌落競爭試驗。結果顯示以台灣塊菌及印度塊菌皆具有較佳之菌落生長，皆能使龜紋硬皮馬勃菌落生長受到影響；尤其菌落競爭勢力上，亦以印度塊菌菌落佔優勢。本試驗結束時，印度塊菌菌落會發生覆蓋龜紋硬皮馬勃菌落。台灣塊菌與龜紋硬皮馬勃之菌落菌絲至培養後期混和生存。試驗期間並未觀察到印度塊菌菌落與龜紋硬皮馬勃菌落及台灣塊菌與龜紋硬皮馬勃之菌絲有融合現象。The purposes of this study were to (1) confirm the effect of truffle inoculation on the seedlings growth of Cyclobalanopsis glauca, (2) observe the competition of Scleroderma areolatum to the mycorrhizae formed either by Tuber formosanom or T. indicum and (3) compare the competition of S. areolatum to the truffle cultured on YMT agar medium.
After the seedlings of C. glauca were inoculated with T. formosanum and T. indicum , the height growth, root collar diameter, top dry weight and root dry weight were much more significantly stimulated than those of non-inoculated seedlings. The T/R ratio of both Tuber-inoculated seedlings was significantly lower than those of non-inoculated seedlings.
S. areolatum could form typical white ectomycorrhizae , when it was inoculated to one year’s old C. glauca seedlings mycorrhized either with T. formosanum or T. indicum two months later after inoculation. The other uninoculated rootlets could be infected by the rhizomorph extended from white ectomycorrhiza.
The rhizomorph could also infect the Tuber-infected ectomycorrhizae and finally enveloped it. Therefore, the inoculation of S. areolatum could reduce or impede the mycorrhiza formation formed by T. formosanum or T. indicum . The Tuber- mycorrhized C. glauca seedlings inoculated with S. areolatum two months later could also stimulate seedlings growth, as the seedlings were inoculated with truffle only.
YMT agar medium was used to test the colony competition between T. formosanum and S. areolatum, T. formosanum and S. areolatum each other. The results showed that the colony growth of either T. formosanum or T. indicum grew much quicker than that of S. areolatum, and could impact the growth of S. areolatum. There was compete dominance for the colony growth of T. indicum , especially. The colony of T. indicum could cover the colony of S. areolatum at the end of the test. The colony of T. formosanum and S. areolatum grew mixedly each other at the late stage. Neither the hyphal anastomoses of T. indicum and S. areolatum, nor the hyphal anastomoses of T. formosanum and S. areolatum were observed.一. 前 言------------------------------------------------------------------------------1

Going Beyond Counting First Authors in Author Co-citation Analysis
Get PDFThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Variations on the Author
Get PDF“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
Appropriate Similarity Measures for Author Cocitation Analysis
Get PDFWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
Dispelling the Myths Behind First-author Citation Counts
Get PDFWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods
koamabayili/VECTRON-author-checklist: VECTRON author checklist
No full textWe have done our best to complete the author checklist relating to the use of animals in the hut study. Note that the objective for the hut study was to evaluate the IRS treatment applications for residual efficacy against Anopheles mosquitoes, including the local An. coluzzii mosquito population. Cows were only used to attract mosquitoes into the huts and no tests were carried out directly on the cows. The author checklist is intended for use with studies where experiments are carried out on animals, which is why we have had such difficulty in completing this for the hut study, as many of the questions do not relate to how the cows were used
