A 2C increase in temperature around the world by 2050, according to one of the scenarios predicted by the Intergovernmental Panel on Climate Change (IPCC), may be advantageous to the physiology and the biochemical and biophysical processes involved in the growth of forage plants such as Stylosanthes capitata Vogel, a legume utilized for livestock grazing in tropical countries such as Brazil.
The conclusion is from a study carried out by researchers in the Department of Biology at the Ribeiro Preto Faculty of Philosophy, Sciences and Languages and Literature at the University of So Paulo (USP).
The outcome of a thematic project conducted under the FAPESP Research Program on Global Climate Change (PFPMCG), the study has just been published in the journal Environmental and Experimental Botany.
"The 2C increase in temperature in the environment in which Stylosanthes capitata Vogel was experimentally cultivated promoted photosynthesis, in addition to increasing the leaf area and biomass of the plant," said Carlos Alberto Martinez, project coordinator and first author of the study.
The thematic project coordinated by Martinez involves researchers from the University of Illinois, Columbia University and the US Department of Agriculture (USDA), in addition to the Consiglio Nazionale delle Ricerche of Italy, the Universitat de Barcelona in Spain, and, in Brazil, the Federal University of So Carlos (UFSCar), the So Paulo State University (Unesp) and the North Fluminense State University (UENF), as well as the Cena at USP, the Botanical Institute and Embrapa.
According to Martinez, Stylosanthes capitata Vogel is a major forage legume in tropical and subtropical regions all over the world. This plant species is highly drought resistant and able to grow in sandy environments.
With global climate change, it is estimated that a moderate temperature increase of slightly greater than 2C could have damaging effects on the pl
