Abstract

Flue cured tobacco plant grows and develops natura1ly in the condition of supplying moderate amount water. Meanwhile, magnesium accumulation makes up 55.3% in the prophase, 38.9% in period of vigorous growth and 5.8% in period of mature. Supplying water excessively or deficiently, less magnesium accumulation in earlier and intermediate stage may exert pressure on absorption in anaphase and result in deficient magnesium accumu1ation in period of mature. In the different parts of tobacco plant, Magnesium distribution percentage is as follows: leafrootstalk in the prophase; leafstalkroot after vigorous growth and vein in every stage. Magnesium distribution percentage in leaf in every stage of treatments with supp1ying moderate water is more than that with supplying water excessively or insufficiently. In excessive or deficient water supply condition, magnesium distribution percentage in root and stalk increases, whereas decreases in leaf.
