    Divergencia citogenética y regulación del ciclo celular en poblaciones naturales de hedeoma multiflora Benth (Lamiaceae): más allá del número cromosómico

    No full text
    PosterHedeoma multiflora es una especie aromática medicinal con amplia distribución en Argentina. La variación cromosómica en poblaciones naturales refleja procesos evolutivos adaptativos, donde la regulación del ciclo celular controla tanto la proliferación como el desarrollo vegetativo. Este estudio investiga la relación entre variación citogenética y características fenotípicas en poblaciones naturales de H. multiflora, evaluando si representan estrategias adaptativas diferenciadas.Instituto de Recursos BiológicosFil: Peralta, Patricia Angelica.

    EFFECTS OF PRE-PLANT SOIL TREATMENTS ON STRAWBERRY IN SICILY

    The 2005 ban by Italy of methyl bromide (MB) has resulted in significant crop management difficulties in pre-plant soil dis-infestation. We report two pre-plant soil treatment techniques and their effects on the performance of new cultivars and selections tolerant to the main root pathogens. The plants grown in soil treated with chloropicrin + 1,3 dichloropropene were the most productive. While neither treatment affected average berry weight, soluble solids content or titratable acidity, the treatment × cultivar interaction was significant and fruits from plants grown in treated soil were firmer than control s. Selection PA 260 and cultivar Florida Fortuna were the earliest, three selections were the most productive and Nora produced the sweetest but smallest fruits

    Strawberry Variety Trial in Sicily.

    The Sicilian strawberry area differs from other Italian strawberry areas for its high earliness with productions that start in November-December. The earliness due to the very low plant winter chilling requirement is a very important characteristic to define the variety adaptability to this environment. Through the "Liste varietali Fragola" project funded by MiPAAF, many new varieties and advanced selections are evaluated annually in Sicily. Here, at the moment, the main variety is Florida Fortuna, followed by Candonga ® Sabrosa and Naiad ® CIVL35. Florida Fortuna, released in Florida, showed to be very interesting especially for its outstanding earliness, a high yield and good fruit quality traits, but it is quite susceptible to biotic and abiotic factors that may affect the survival of plants. The study was carried out in 2011-'12 at the experimental fields located in Marsala (TP). The cultural technique adopted was the typical Sicilian one. The performance of 7 new varieties and 4 selections are here described. Three of these selections were obtained by the Sicilian breeding program - carried out by the S.Ag.A Department and coordinated by CRA-FRF. Florida Fortuna confirmed to be the earliest and productive variety. Sabrina, coming from Spain, provided the firmest fruits with the highest total soluble solid content, while the Italian Rania produced the biggest fruits. The following selections are at the final stage of evaluation and they may be released in the near future: PA 260.3 showed to be early and to produce firm and sweet medium-small fruits. PA 20, which provided the yield as Florida Fortuna, has an early ripening and its fruits are firm with an high content of total soluble solids. PA 3 and Pir 2 stood out for high firmness, sweetness and very bright red-orange fruit colour

    Going Beyond Counting First Authors in Author Co-citation Analysis

    The 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
