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.
