The increase in atmospheric temperature and alteration of the hydrological cycle are the main threats of climate change to wheat crop (Triticum aestivum L.). Furthermore, feeding a population which annually grows 1.1 %, promotes the expansion of agricultural frontier to soils with growth constraints. In this context, when in South America La Niña events occur, the cold phase of the ENSO climate phenomenon, in a greater area of the wheat crop region increases the risk of drought stress during grain filling. The aim was to study the response of five wheat cultivars to two irrigation treatments: Control and Stress. The experiment was conducted in a greenhouse using the bread spring wheat cultivars LE 2249, LE 2331, LE 2333, Baguette Premium 11 and Biointa 1001. Relative water content (RWC) was determined during the stress period, from anthesis to physiological maturity, and grain yield and its components at harvest. No significant interaction between cultivars and irrigation treatments were observed for yield per plant and RWC (P=0.3086 and P=0.0589, respectively), but it was significant for kernel weight and harvest index (P=0.0188 and P=0.0405, respectively). The cultivar LE 2333 was hardly affected by the Stress treatment, while Baguette Premium 11 and LE 2249 showed an intermediate response. In contrast, LE 2331 and Biointa 1001 were the most susceptible cultivars, decreasing their yield per plant 21.0 % (P=0.0206) and 21.2 % (P=0.0284), respectively. An early stress threshold in Biointa 1001 caused that kernel weight and RWC were not modified due to a decrease of kernels per plant. Whereas a late threshold in LE 2331 caused that both, kernel weight and RWC were affected. Cultivars with the latter type of response would be more suitable for regions with deep soils and/or with high probability of rain after anthesis.

German consumers (n=200) evaluated the eating quality of beef and lamb from animals fed A: grass, B: grass plus grain (0.6% LW), C: grass plus grain (1.2% LW) or D: grain. Conjoint analysis was conducted to determine the relative importance of country of origin (Argentina, Switzerland, Uruguay, United Kingdom), animal diet (grass, grass plus grain, grain) and price (low, medium, high) in purchasing decisions of fresh beef (n=100) and lamb (n=100). Beef and lamb overall acceptability was higher for treatment C, followed by B with treatments A and D being the least preferred, indicating greater eating quality for meat from animals fed a high level of grain upplementation. The most important attribute for purchasing decisions was country of origin followed by animal diet and meat price, for both beef (68, 16 and 16%) and
lamb (46, 34 and 20%), respectively. Highest positive utilities were found for Argentina, grass and low price in beef and for Switzerland, grass, and low price in lamb. Consumers preferred the eating quality of meat from animals fed with high levels of grain supplementation. However, conjoint analysis showed a preference
in purchasing decisions towards meat from animals fed mainly on grass in the low price range. |
