摘要:
Three tobacco varieties were grown under four soil fertility conditions. Leaf samples were taken at bloom stage from upper and lower positions and analyzed for eleven elements. Results show how leaf position and variety affect leaf mineral composition with variable soil conditions. Therefore, variety and leaf position should be clearly defined before leaf nutrient levels can have a suitable degree of diagnostic value. However, variety differences were of less importance because nutrient concentration differences were generally related to appropriate changes in yield measurements.
