title: [Preliminary study on radiant spectra of the leaves of paddy and upland rice].
abstract: The characteristics of the radiant spectra (i.e. absorption, reflectance and transmission) of leaves of paddy and upland rice were studied. The experiment proves that the characteristics of the radiant spectra of the seedling leaves of paddy and upland rice is basically the same in the range of 200-800nm, and their chlorophyll content of the leaves is also quite near (the average values for paddy and upland rice are 4.25mg/g and 4.28mg/g, respectively). However, the absorption of the flag leaves of upland rice is higher and the transmission is lower compared to paddy rice in the heading-flowering period, while the reflectance is almost the same except for 550nm. The chlorophyll content in the leaves of upland rice is approximate twice as that of paddy rice (the average values of paddy and upland rice are 0.86mg/g and 1.86mg/g, respectively).
