No full textEffetti dello stress idrico sul flusso traspirativo e sulla resistenza del manto vegetale di una coltura di cotone (Gossypium hirsutum L.)
No full textSi riportano i risultati di una ricerca svolta a Gaudiano (PZ) su coltura di cotone (cv. GSA 75) sottoposta a due periodi di stress idrico, relativa al calcolo a livello giornaliero della resistenza della coltura (rc) al flusso traspirativo, quale parametro incognito nel modello di Penman- Monteith.
Sono state studiate le relazioni tra la suddetta resistenza ed i parametri colturali quali il LAI delle diverse fasi fenologiche e l'evapotraspirazione relativa della coltura. I risultati ottenuti evidenziano che la resistenza colturale opposta al flusso evapotraspirativo, a prescindere dallo stato idrico e dal LAI è fortemente influenzata dallo stadio fenologico della coltura
Effetto della carenza idrica sull'architettura di piante di peperone allevato in serra
No full textResults of a trial carried out in order to study the effect of water deficit on pepper plant architecture are
reported. Water stress affected plant architecture reducing the leaf angle incidence and schifting the mode of leaf
angle frequency distribution from 90° above the nadir in well watered to 20° in water stress condition. Leaf movements were significantly correlated to the turgor potential of the leaves

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
Enhancing Vegetative Growth of Quinoa and Soil Properties under Water Shortage through Targeted Organic Amendments
Get PDFThe scarcity of water resources is considered a major threat and challenge for agriculture.
Water limitations could strongly affect the growth and development of many crops including quinoa, a
nutrition-rich, climate-resilient crop that is gaining attention globally. Organic amendment application has been reported as a suitable option to mitigate the detrimental impacts of water shortage on soil and plant growth. In this context, two experiments were conducted on Chenopodium quinoa “Titicaca”; in the first experiment, we investigated the effect of different organic amendments, namely woodchips biochar (Bw), vineyard pruning biochar (Bv), and vermicompost (V), applied (alone and mixed) at 2% soil dry weight, on soil properties and the plant biomass of quinoa subjected to a water stress period during vegetative development. Among organic amendments tested, Bw and Bw+V increased plant biomass on average by 15%, while Bv and Bv+V reduced the plant biomass by 62% compared to nonamended
soil (C). A significant reduction in soil pH was observed with Bw (7.61), while BV increased
pH (8.04) compared to C (7.76). The Bw and Bv also reduced soil bulk density (BD) (1.19 g/m3 and 1.13 g/m3, respectively) compared to C (1.28 g/m3). As Bw performed better in the first experiment, the second experiment assessed only Bw at different doses, i.e., 0%, 2%, and 4% under water shortage by restoring only 50% evapotranspiration losses, when soil water content reached the 50% of available water content. Considering the Bw rates, the plants treated with Bw2% showed 34% and 19% more biomass and 36% and 66% more panicles than Bw0% and Bw4%, respectively. The Bw2% decreased the soil pH (7.79 versus 7.85) and electrical conductivity (286 versus 307 μS/cm) compared to Bw0%, which was not different from Bw4%. No differences were observed in BD between Bw0% and Bw2% (on average 1.28 g/m3), while BD decreased in Bw4% (1.06 g/m3). The findings of both experiments
highlighted that the appropriate type and dose of biochar could improve soil properties and help quinoa plants to grow better under water-limited conditions
Yield response of sweet sorghum (Sorghum bicolor L. Moench) under different water and fertilizer regimes in environments of Basilicata
No full textThe results of two-years trials (1991-92) carried out in two
environments of Basilicata (Policoro and Irsina) on 4 cultivars of sweet
sorghum (Foralco, Keller, Sofra and Vespa) in order to evaluate their
yield potential under different irrigation and fertilization regimes are
reported. The total biomass and green stalk production generally
showed higher values at Policoro than at Irsina and far the crop
receiving 100% maximum evapotranspiration (ETc). Among cultivars,
Keller always gave higher yields and reached, at Policoro, peak values
of 72 t ha-l of total biomass and 63 t ha-l of green stalks in the most
irrigated treatment, against values respectively equal to 64 and 56 t ha-1,
58 and 49 t ha-l, 48 and 37 t ha-l for Foralco, Sofra and Vespa. The
refractometric index of the stalk cell-juices was influenced only by the
growing environment, the highest values being recorded at Policoro
with respect to Irsina (on an average 18.9% versus 15%).
At Irsina, the total biomass and green stalk yields of the four
cultivars were about 25% lower
