Single Leaf Photosynthesis of Rice Plants under Field Conditions : I. Aspects of single-leaf photosynthesis and the regulating factors

[摘要] Single-leaf photosynthesis in situ were observed under field conditions and the regulating factors investigated. The light intensity at the leaf surface was shown to act as the leading factor. However, it was also suggested that there were some other factors greatly affecting photosynthesis. Light saturation points varied from case to case, but they were lower than 0.65 cal cm-2min-1 in most cases.
