摘要: Potassium (K) deficiency reduces photosynthesis and biomass production of crop plants also renders them vulnerable to drought stress, whereas elevated carbon dioxide (CO2) has a positive effect on yield ameliorates the adverse effects stress. This study aimed characterize physiological responses wheat (Triticum aestivum L.) stressed with K under CO2 conditions. Increased caused by as consequence increased water use efficiency was absent in young K-deficient plants. Shoot concentration negatively affected particularly conditions, content per plant greatest supplied adequate water. Specific leaf weight carbohydrate accumulation source leaves clearly impeded impact both well watered drought-stressed Adequate fertilization is prerequisite for efficient harvesting atmospheric through photosynthesis, decreased transpiration, changing soil moisture
