ABSTRACT.
The in vitro and in vivo control of Phyllosticta citricarpa (citrus black spot, CBS) on citrus fruits was evaluated using 14 essential oils (EOs) extracted from Uruguayan native plants. In vitro, volatile components of Chenopodium ambrosioides completely inhibited fungal growth. The dilution agar test showed that fungus reproduction was completely inhibited by Conyza bonaerensis essential oil (EO). The other 12 EOs tested showed high inhibition after 10?15 d, presenting fungistatic effects. In vivo, assays were performed on fruit of lemon [Citrus limon (L.) Burm] and Valencia orange [Citrus sinensis (L.) Osbeck] in order to evaluate the effects of liquid and volatile EO phases on reproduction. Typical lesions of CBS without reproductive structures were exposed to Ch. ambrosioides and C. bonaerensis EOs for 20 d at 27 C and cycles of 16 h light and 8 h dark. The volatile components of Ch. ambrosioides were able to control 100% of P. citricarpa reproduction in orange and lemon fruit. The growth of other fungi such, as Colletotrichum gloeosporoides and Fusarium sp., was also inhibited. Nevertheless, the liquid phase was not effective to control the pathogen. In another test, carton boxes with 20 fruits, each presenting typical CBS
symptoms, but without the presence of reproductive structures, were exposed to 0.01 and 0.05% of Ch. ambrosioides EO (w/v). The fruits were stored at 5 C for 20 d and then kept for 7 d at room temperature. A 40% reduction of reproduction was observed in citrus fruit exposed to 0.05% of EO. GC?MS analysis of EOs showed that Ch. ambrosioides EO was composed of 76% monoterpene compounds (49 and 27% of oxygenated and hydrocarbons, respectively), while C. bonaerensis EO presented 17% monoterpenes and
10% sequisterpenes.

En este trabajo se realiza una recopilación, generación y análisis de variables agroclimáticas, caracterizando su comportamiento en base a registros y estadísticas del período 1980 - 2009. La información se representa en mapas con distribución territorial (isolíneas dentro del país) y de frecuencia temporal (percentiles 10, 33, 50, 66 y 90).
Esta caracterización de la frecuencia temporal en base a percentiles busca caracterizar la variabilidad interanual de las distintas variables durante el período de estudio, caracterizando no solamente el promedio del período (percentil 50) sino también los valores de los 10 años con registros superiores (percentil 66) o inferiores (percentil 33) y también de los 3 años que registran los valores más extremos tanto superiores (percentil 90) como inferiores (percentil 10). Asimismo, se anexan tablas con los datos promedio mensuales para cada variable en cada localidad seleccionada para su estudio. |
