The resistance estimation of some variety’s and hybrids of Vitis vinifera L. against the attack produced by Botryotinia fuckeliana (de Bary) whetzel pathogen agent
Get PDFThe cultivation of the resistant varieties has an important contribution
in reducing the number of treatments and also the cost with phytosanitary
protection of the grape vine.
In 2008 year there were made observations regarding the grape vine
varieties resistance against the attack of Botryotinia fuckeliana fungus, in the
U.S.A.M.V. ampelographyc collection from the “V. Adamachi” Iaşi farm.
According with agro biological descriptors for grape vine variety’s,
proposed by O.I.V. (1993) and mentioned by Ţârdea C. and Liliana Rotaru
(2003), the resistance level of grape vine against gray mold can be made
appreciating the attack level on leaves and grapes.
The leaves are observed after flowering and the grape observations
are made after harvest, using for that an interpretation scale with marks from
1 to 9, according with attack level which is between 0 and 100%.
The varieties evaluation regarding their resistance against
Botryotinia fuckeliana has been made examining the grapes before harvest
and giving marks according with the existent level of attack.
After the experience accomplish it has been made an actualization
regarding the resistance of some varieties and hybrids of Vitis vinifera L. to
the attack of the Botryotinia fuckeliana fungus in the global heating
perspective.
Between grapes varieties or hybrids for consumption, the best results
were presented by the varieties: Coarnă albă, Moldova, Coarnă neagră and
Roz românesc, which have registered an reduced level of attack, under 5%.
Between the varieties or hybrids for wine, there has been pointed out
the following: Băbească neagră, Merlot, Andre and Negru de Drăgăşani,
which have registered a reduced level of attack, under 10%.
The most sensitive variety was Galbenă de Odobeşti, which recorded
the highest degree of attack (76.72%), followed by varieties: Frâncuşă,
Grasă de Cotnari, Busuioacă de Bohotin and Cabernet Sauvignon, which
had a degree of attack over 50
The testing of effectiveness and economical efficiency of some fungicides applied to vines against Botryotinia fuckeliana (de Bary) whetzel fungus, in SDE "V. Adamachi" Iaşi conditions
Get PDFAgainst grape vine gray mold has been elaborated different control
plans. Most researchers discovered that the treatments had the highest
efficiency when it is applied in the next phenological moments: to the flower
shake-up; to the grape compaction and to the grape greenness stadium.
To accomplish the experiences contained in this paper, we attend to
the phenological phases of Fetească regală genus, following the optimization
of the treatments plan, applied against grape vine gray mold.
In the paper are presented 3 new treatments plan, starting with the
basic plan which included 3 treatments and continued with a cyclic
elimination of treatments in every phenological moment.
Experiences were achieved in 2007-2008 agricultural year, in the
experiments were tested a number of 4 fungicides with different active
substance and method of action.
The main objectives were determining the effectiveness and efficiency
of fungicides tested, and checks the opportunity of application phytosanitary
treatments against gray mold disease of Vine, in the 3 phenology set points.
Effectiveness and economic efficiency of fungicides was calculated
taking into account the cost of plant protection products, the level of yields
obtained (determined by gravimetric method), correlated with the degree of
attack produced by the fungus Botryotinia fuckeliana (by Bary) Whetzel.
To determine the opportunity of application the 3 treatments against
gray mold of vine, in the 3 phenology set points, it was made a comparative
analysis of influence factors from the variants and also between the 4
experiments.
Analyzing the yields obtained it was found significant differences
between the 4 experiments and between the variants.
Regarding the degree of attack recorded in the 4 experiments it was
found that in the conditions of agricultural year 2007-2008 there were no
notable differences

Aspects of production and economical - financial results of Galati county agriculture
No full textRomania's accession to the European Union marked a new stage in our country's agriculture. Thus, Romania has to
adapt to the European model of agriculture that is based on competitiveness, market orientation, environmental
protection, integration of agriculture with the environment and forestry, etc.
In Galati County economy, agriculture occupies an important place because of existing arable and agricultural land,
livestock, poultry, land improvement and the availability of tractors and agricultural machinery.
In Galati County, the largest percentage of agricultural area holds the arable land (approx. 88.74 %).
On average, crops with the highest share of arable land in the county of Galati are cereals grain (67 %) and oil plants
(23 %). Other cultures have lower rates, not exceeding 3 %. The main animal species are: cattle (average 45,502 heads),
pigs (average 71,839 heads), sheep (averaging 243,556 heads), birds (average 9,010,264 heads), etc.
Increase economic efficiency in the plant and animal sector, can be achieved by increasing average yields, improve the
product quality, expansion of storage facilities (it can be capitalized the products at a higher price), increasing the
investments in agriculture and animal husbandry by accessing funds grants, bank loans, etc.
Competitiveness in agriculture also can be achieved by forming multi activity farms, market-oriented, by their
association and cooperation, accessing grant funds for necessary investments in farms or processing units, etc
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

Considerations on Galati county pedo-climatical conditions and their influence on agricultural development
No full textRomanian rural economy dominated by agriculture in large part, is still poorly integrated in the market economy.
Favourable geographical conditions, topography, climate, fertile soils, skilled labour, can make from Romanian
agriculture an attractive and profitable area of activity. As an economic sector, agriculture occupies in the county of
Galati, a leading place due to the rich rivers, which allows the practice of an intensive agriculture.
This is due also from the great potential of Galati County, which, farmers, supported by central and local authorities, are
trying to fully exploit it. The county, by its morphological features, provides favourable conditions for various
agricultural activities. There are presented also some negative phenomena and processes as soil erosion, landslides,
areas with salty soil, sand or flood soils that require specific actions.
Climate changes in recent years are affecting many sectors of the economy. Agriculture is one of the area’s most
exposed because of its dependence on weather conditions. Extreme weather events more frequent (such as floods, heat
waves and droughts) have negative impact on crop yields, increase the distribution and intensity of disease, and also
weed growth because of temperatures and higher humidity, submission periods of flowering trees, longer wine season,
changes in other natural cycles of plants, changes in the timing of agricultural operations, etc
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
