However, climate change has generated variations in temperature and precipitation that negatively impact the maturation of crops. To quantify the combined effect of drought stress and elevated temperatures, plants of Coffea arabica cv. Ouro Verde IAC H5010-5 were evaluated under the climatic conditions of La Molina, Peru, with four treatments (WT: 100% available water + air temperature (22.7°C); -WT: < 50% available water + air temperature (22.7°C); W+T: 100% available water + elevated air temperature (22.7 + 2.5°C), and -W+T: < 50% available water + elevated air temperature (22.7 + 2.5°C)). In general, morphological indices were decreased by -WT and -W+T (P≤0.05). Plants subjected to -W+T, significantly affected quality indices like root:shoot ratio, robustness, and Dickson (P≤0.05). The -WT plants had a nitrogen content of 2.46%, the highest nitrogen content compared to other treatments. Isolated and combined stress had negative differential effects on plant development, and water scarcity (as an individual factor) was the repercussion, in most cases, that was more prominent than the effect of high temperature. 2023 artículo científico 0120-9965 https://www.redalyc.org/articulo.oa?id=180377653002 https://www.redalyc.org/journal/1803/180377653002/ https://www.redalyc.org/journal/1803/180377653002/html/ https://www.redalyc.org/journal/1803/180377653002/180377653002.epub https://www.redalyc.org/journal/1803/180377653002/movil 10.15446/agron.colomb.v41n1.105778 en http://www.redalyc.org/revista.oa?id=1803 Agronomía Colombiana application/pdf Universidad Nacional de Colombia Agronomía Colombiana (Colombia) Num.1 Vol.41 |
