Universidad de Castilla-La Mancha. Durum wheat (Triticum turgidum L. var durum (Desf.) Husn.) is the 10th most important cereal in the world, with an average annual production of 40 million Tm representing the 5% of total wheat production. The Intergovernmental Panel on Climate Change (IPCC) (IPCC. 2014) has projected a global warming trend of 0.3-1.7ºC by 2100, which is a serious concern for agriculture in the medium to long term. In addition to this, short heat waves (SHW), a period of several consecutive days with high temperatures above the developmental optimum, will become more frequent. In wheat, the occurrence of very high temperatures during anthesis has a negative impact on yield by reducing spike fertility and grain filling period and impairing grain filling. In addition, high temperatures also affect grain quality by altering the biosynthesis and accumulation of many grain compounds. In this work, we investigate the effect of post- anthesis SHW on durum wheat grain under field conditions. At anthesis, all spikes at the same physiological stage were labelled and the SHW stress was applied for one week using tents covered with transparent polyethylene film. The temperature inside and outside the polyethylene tents was monitored using data loggers. At maturity, all the labelled spikes were harvested. After threshing, the grains were milled and subsequently used for the determination of the total carotenoid content and profile.
