Growth regulators, dates of treatments, yield and quality of broad bean (Vicia faba L. ) and Florence fennel (Foeniculum vulgare Mill. var. azoricum Thell. ) "seed"
No full textOn Florence fennel chlorocoline chloride (CCC), ethephon, (ET) pachlobutrazol (PCB) GA3, GA4/7 and benomyl were sprayed for two years when the first formed 'seeds' were starting to ripen. In both years the 1000 'seeds' weight was higher for 'seeds' coming from the untreated plants. In the first year, 'seeds' from plants treated with ET showed a lower germination percentage, speed of germination and germination value. In the second year the speed of germination and germination percentage were lower for 'seeds' treated with PCB.
It can be concluded that treatments had no beneficial effects on 'seed' germination of fennel.
Faba bean plants, at 6-leaf stage, at flowering of the first node and 11 days later were treated 1,2 or 3 time with PCB, CCC, GA3 and 2,4-dichlorophenoxy acetic acid (2,4-D) at 2 rate of application.
GA3 treatments increased the number of aborted seed; the yield per plant decrease by increasing the rate and the number of treatments.
Double and triple CCC treatments lowered 1000 seed weight but they improved germination value 6 months after harvest. Later treatments with PCB increased the germination value; 2,4-D elevated seed size and 1000 seed weight. In general, growth regulators had a little influence on germination percentage
Topping time, yield and quality of Florence fennel and basil seed
No full textThe effects of inflorescence removal time (topping) relative to stage of plant growth in Florence fennel (Foeniculum vulgare Mill. var. azoricum Thell.) and basil (Ocimum basilicum L.) were examined.
In the fennel during the first year 5 topping treatments were made: 1) control; 2) topping at boot stage; 3) topping at emergence of primary umbel (PU) with removal of the PU+first order, 4) topping at emergence of PU with removal of the PU only; 5) topping at beginning flowering of PU. In the second year topping treatments happened at boot stage, at initial and full flowering of PU.
In the basil 8 treatments were planned:1) control; 2) topping the main stem at appearance of the spike; 3) as treatment 2 by topping all the stems; 4) treatment 2, 7 days later; 5) treatment 3, 7 days later; 6) treatment 2 topped 14 days later; 7) topping apex and 2 expanded leaves below of all stems; 8) topping apex and 3 expanded leaves below of all stems
Topping treatments did not influence the yield and yield component of fennel and basil.
For the fennel in the first year germination percent was higher for the "seed" coming from PU and when the topping occurred at beginning of the flowering. "Seeds" from PU reached earlier predetermined germination percent and showed a higher germination value. In the second year, germination percent decreased when topping happened at boot stage and at beginning of the flowering, while the time to reach a pre-determinate germination percent was shorter when elimination of the PU occurred at full flowering.
In the basil higher and lower germination percent resulted by topping according to treatment n. 7 and n. 6 respectively. Longer time to reach ninety-five percent of the final germination was observed when plants were topped as treatment n. 2
Cell size, transplant age and cultivars effects on timing field production of broccoli (Brassica oleracea var. italica Plenck) for processing
No full textThree cultivars of broccoli were seeded in three containers with cell size ranging from 4.78 to 39.72 cm3 and at density of 1611 to 498 plants-m-2. The aim of the study was to determine the effects of container size, age of seedlings (optimal, 7 and 14 days older) and time of harvest, in order to produce heads in December and January because of the demands for continuity of supply from factories.
Age of seedlings did not influence the marketable yield of central heads (CH); older seedlings reduced hollow stem incidence and delayed maturity (days from sowing to first harvest) by 17 days. 'Gran Vert' was less productive and showed a lower incidence of hollow stem. First harvest for 'ML 145' happened at end of February while 'Gran Vert' began to produce on late November and 'XPH 4142' on mid December. When container cell size was less than 20.20 cm3 the yield of CH and lateral head was lower. Earliness was affected by container size and age of transplant and the cultivars showed a different behaviour. The goal to produce heads in December and January was achieved
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
Appropriate Similarity Measures for Author Cocitation Analysis
Full text linkWe 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
