Abstract
A simulated experiment was conducted to evaluate the effects of climate warming on the bioaccumulation, translocation and distributions of mineral elements in Solanum tuberosum L. by increasing temperature and CO2 concentration in an artificial climate greenhouse. The objective was to explore the effects of global warming on crop mineral nutrition and the long-term effects on agricultural ecology. The results showed that the bioaccumulation of Cu, Mg, Fe, Mn, and Cd in Solanum tuberosum L increased in whole plant with the combined increase of temperature and CO2 concentration. The mineral elements in leaves, stems, tubers, and root tissues of Solanum tuberosum L showed different changes, and the trend and degree of change vary depending on the element. The migration of most elements from roots to leaves and stems showed a slight increase with the increasing of temperature and the concentration of CO2, while the migration from roots to tubers remained relatively stable. In addition, the available content of most mineral elements (except K) in the soil increased with increasing temperature and CO2 concentration. These results suggested that climate warming could change the bioaccumulation, migration, and distribution dynamics of mineral elements in Solanum tuberosum L.
