Relationship between nitrogen content in leaf blades and photosynthetic rate in rice plants measured with an ir gas analyzer and an oxygen electrode


, : Relationship between nitrogen content in leaf blades and photosynthetic rate in rice plants measured with an ir gas analyzer and an oxygen electrode. Japanese Journal of Crop Science 48(4): 551-556

The photosynthetic rate, diffusive conductance and stomatal aperture in gasometric system were positively and closely correlated with N content in leaf blades. A high positive correlation was found between diffusive conductance or stomatal aperture and photosynthetic rate in leaf blades with wide range of N content. The photosynthetic rate increased due to the increase in the diffusive conductance and stomatal aperture in leaf blades with higher N content, as reported in the previous paper. The photosynthetic rate in the substrate with the concentration of 20 mM NaHCO3 was positively correlated with N content in leaf blades. The increase of N content in leaf blades from 7.1-19.1 mg/dm2 increased in the photosynthetic rate measured with the IR gas analyzer by 2.5 times, while it increased in the photosynthetic rate measured with the oxygen electrode by 2.0 times. To examine the obtained data in detail the increase in the photosynthetic rate was compared in leaf blades on the same position of the stem. The incline of regression lines of the data measured with the gas analyzer were much larger in 2nd, 3rd and 4th leaf from the first expanded leaf, compared with those measured with the oxygen electrode. It is suggested that the difference between the slope of the 2 regression lines of the same leaf position indicated the influence of the stomatal aperture and diffusive conductance on the increase in photosynthetic rate with the increase in N content in leaf blades.
