Bright leaf tobacco plants were cultured to study the effects of varied amounts of phosphate application on the maturity of tobacco leaves. (1) The leaves in lower phosphate plots abscissed earlier than those in higher phosphate plots. (2) The P content of upper leaves was almost constant independent of amounts of phosphate applied, but those of lower leaves in lower phosphate plots were remarkably low. (3) The N content of various parts of tobacco plants in higher phosphate plots was slightly higher than those in lower phosphate plots. (4) In higher phospate plots, the maximum content of soluble carbohydrate in leaves was obtained later than those in lower phosphate plots. Considering that mentioned above, it seems to be reasonable to conclude that the time of maturity of tobacco leaves in higher phosphate plots is later than those in lower phosphate plots.
