Abstract:
Pear (Pyrus communis) is reasonably well-adapted to the average climatic conditions of southern Uruguay, but the climatic variables are not always agreeable for satisfactory production. The objective of this research was to evaluate the impact of climatic factors, on yield components (average fruit weight and productivity) of 'Williams' pears on two different rootstocks ('OH×F40' and 'BA29'). The experiment was established in July 2003 at Instituto Nacional de Investigación Agropecuaria - INIA Las Brujas (34°67?S; 56°37?W). According to Köppen-Geiger classification, the climate of the studied region is ?Cfa? and the soil type is a Typic Argiudoll. To analyze the contribution of climatic factors on productivity of pear trees, a principal component analysis (PCA) was applied using the statistical software R. The correlations between yield components and precipitation, cold units, chill hours (≤7.2°C), relative humidity, evapotranspiration and average temperature were studied from the growing season 2014/15 until 2017/18. Climatic data were collected from the meteorological station at INIA Las Brujas, located less than 500 m from the trial plot. Climatic factors had a more significant effect on 'Williams' productivity than the rootstock factor. One main factor affecting seasonal productivity was chill hours. The average productivity values for the two rootstocks during the cycles 2015/16 and 2017/18 was zero and 7.2 t ha‑1, respectively. During the seasons where chilling was not the limiting factor (>500 chill hours), productivity was significantly higher (25.3 and 42.8 t ha‑1 on average for 2014/15 and 2016/17 seasons, respectively). Precipitation during fruit growth and flower induction and differentiation was another main factor affecting productivity in the current and next season. Even though cumulative yield was significantly higher in OH×F40 compared to BA29 (85.9 vs. 64.8 t ha‑1, respectively) no consistent differences were detected between rootstocks seasonally.

RESUMEN.- Amaranthus hybridus (syn: quitensis), conocido como yuyo colorado, es actualmente una de las malezas más importantes en los sistemas agrícolas uruguayos, generando graves pérdidas en la producción de cultivos por su elevada capacidad de competir por recursos como agua, luz y nutrientes. Recientemente, se observaron casos de falla de control después de la aplicación de glifosato, principal herbicida utilizado en su manejo.
El objetivo de este trabajo fue determinar el nivel de resistencia a glifosato en los biotipos de A. hybridus colectados en Uruguay con presunta resistencia a glifosato, y analizar la posible presencia de la triple mutación TAP-IVS en el sitio activo de la enzima EPSPS (5-enolpiruvilshiquimato-3-fosfato sintasa) como mecanismo de resistencia. ----- SUMMARY.- Amaranthus hybridus (syn: quitensis), known as smooth pigweed, is currently one of the most important weeds in Uruguayan agricultural systems, generating serious losses in crop production due to its high capacity to compete for resources such as water, light and nutrients. Recently, cases of lack of control have been observed after the application of glyphosate, the main herbicide used in its management. The objective of this work was to determine the level of resistance to glyphosate in the biotypes of A. hybridus collected in Uruguay with presumed resistance to glyphosate, and to analyze the possible presence of the triple mutation TAP-IVS in the active site of the EPSPS enzyme (5enolpyruvylshikimate-3-phosphate synthase) as a resistance mechanism.
