| Abstract: | In a pot experiment with flue cured tobacco, the plants were foliar sprayed with rare earth solution after transplant. Determination made 45 days later showed that rare earth solution at 660 mg/L increased dry matter, photosynthesis rate, ATP content, CAT activity and NR activity by 17.08, 34.46, 34.41, 24.51 and 43.11%, respectively as compared to the control. Dry matter accumulation, K 2O content, protein, total sugar and total N were raised by 49.62, 28.96, 12.00, 14.13 and 25.84%, respectively, as was determined at the stage of 85 darys after tobacco transplant. |
