| ABSTRACT |
| The growth, chlorophyll composition, photosynthesis, respiration, K uptake and root K+ secretion of flue-cured tobacco as affected by different concentrations of N supplied as urea, NaNO3 and NH4NO3 were studied under the experimental condition of sand culture. The results showed that the content of K in the flue-cured tobacco was not merely related with root vitality and uptake but also closely related with root cell membrane structure and K+ secretion. |
| Key Words: fertilizer N forms, flue-cured tobacco, K uptake, physiological metabolism, root K+ secretion |
