Abstract:
Spectral reflection and chlorophyll content are measured respectively by Unispec spectrometer and SPAD chlorophyll meter from initial flowering to maturing of two soybean cultivars.The chlorophyll content of Hejiao 98-1667 was higher than that of Hefeng 55 in each measured period.The spectral reflectance of Hefeng 55 was higher than that of Hejiao 98-1667.A chlorophyll reflection absorption peak was observed in 510-610 nm wavelength,which maybe a unique eigenvalue of soybean leaves.Statistical analysis showed chlorophyll content of leaves significantly correlated to their spectral vegetation indices such as mSR705,mND705 and PSSRc,which suggests that the chlorophyll content of the leaves of soybean can be monitored by measuring the leaf spectral method.
