Differences varietales de l'absorption de Potassium (Rb86) dans certains porte-greffes de vigne. II.Cinetiques de l'influx de Rb86 dans racines excises.
No full textLe travail de création de nouveaux porte-greffes de vigne el l'évaluation de leur valeur agronomique a connu une période de grand développement surtout dans les premières années après l'invasion phyllosserique. Le modèle d'absorption du K+ (Rb86) a été examiné sur quatre porte-greffe de vigne en employant des fragments de racines excisées
L'appassimento del grappolo di vite causato dal disseccamento del rachide: nuovi contributi terapeutici.
No full textLa fisiopatia calcio-correlata denominata in viticoltura "disseccamento del rachide" è legata all'intensificazione delle tecniche colturali che inducono incrementi di vigoria alle piante. Buoni risultati contro il disseccamento del rachide sono stati ottenuti con trattamenti fogliari a base di magnesio effettuati in prossimità dell'invaiatura e con trattamenti a base di GA3 a 100 ppm eseguiti dopo 14 giorni dalla fine fioritura
Controle en pot de l'interation entre charge par cep et fumure azotée sur la production et la nutrition du Cabernet Franc.
No full textLes effects séparés des apports azotés et charges variables ont été avertis dans les domaines différents. La fertilité des bourgeons apparait influencée seulement par les charges tandis que le poids moyen del baies à la maturation change aussi en function de l'apport azoté. Le différentes charges en outre, ont influencé de manìere statistiquement significative les contenus de sucres à la maturation des baies, de acide malique et de substances colorantes
Risultati quadriennali sull'impiego in viticoltura di concimi complessi contenenti azoto ritardato e magnesio.
No full textLo studio, condotto per quattro anni, in diverse situazioni viticole utilizzando concimi contenenti azoto ritardato (Isodur, Ureaform) ha fornito risultati di rilievo soprattutto sulla qualità di sette varietà di Vitis vinifera (Bonarda, Barbera, Merlot, Lambrusco a foglia frastagliata, Schiava) in cinque aree viticole del Nord Italia. i concimi testati hanno avuto in certi casi influenze significative sull'accrescimento vegetativo delle varietà di vite controllate
Influence de la carence ou de l'excès de fer apporté par voie foliaire sur la composition minérale et biochimique, et sur les paramètres de la production de vignes chlorotiques
No full textApplication of iron based foliar sprays to chloritic wines can augment, sometimes very greatly, the iron concentration is the leaf blade. Resulting in a reduction in the concentration of macroelements and in some phytotoxicity due to an excess of non metabolizable iron.
At the same time, the concentration of amino acids and notably of proline (stress index) is increased. The application of these foliar sprays was insufficient to resolve cases of iron chlorisis
Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe 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
Full text link“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
