 note = {Analysis of the crop nutritional condition plays an important role in the development and application of low-input, sustainable, and environmentally friendly agricultural methods and to save limited resources. Therefore, it is necessary to have a simple and accurate method for conducting this analysis to aid decision-making. In this study, we estimated the ribulose-1,5-bisphosphate carboxylase/oxygenase (RuBisCO) and chlorophyll contents of the leaves of the common buckwheat (Fagopyrum esculentum M.) by statistical analysis using the normalized differential spectral index (NDSI) and other pretreated spectral data to evaluate potential photosynthetic activity in crop breeding programs to achieve high yield. The highest determination coefficient (R2) was recorded for chlorophyll a using the partial least-squares regression (PLS regression) method. The R2 value related to RuBisCO contents was relatively lower and the accuracy of estimation for RuBisCO was midway between that for chlorophyll a and chlorophyll b. The R2 value of RuBisCO/soluble protein was higher than that of RuBisCO in fresh leaves. The system of ultraviolet-induced fluorescence provides a new method for fluorosensing to evaluate the nutritional status of plants using the key biochemical that is related to the dark reaction, as well as PAM, which is related to the light reaction in photosynthesis., Article, 信州大学農学部AFC報告 12: 1-9 (2014)},
