ABSTRACT.
The occurrence of Citrus exocortis viroid (CEVd), Citrus bent leaf viroid (CBLVd), Hop stunt viroid (HSVd), Citrus dwarfing viroid (CDVd), Citrus bark cracking viroid (CBCVd) and Citrus viroid VI (CVd-VI) in Citrus spp. cultivated in six provinces of Uruguay was surveyed in 2008- 2009 and 2009-2010 growing seasons using Northern blot hybridization. Sixty two per cent of surveyed trees were infected with either single or mixed viroid inocula, the latter being more abundant. CBCVd and CVd-VI were not detected in the samples analyzed. HSVd showed the highest prevalence (92%) among infected plants followed by CDVd (50%), CEVd (23%) and CBLVd (19%). The most frequently observed viroid combination was HSVd+CDVd. Our results showed that CEVd, CBLVd, HSVd, CDVd are widespread throughout citrus orchards in Uruguay and highlight the presence of mixed viroid infections. |

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.
