Comparison of reflectance, interactance and transmission modes of visible-near infrared spectroscopy for measuring internal properties of kiwifruit (Actinidia chinensis)
نویسنده
چکیده
Three modes of visible-near infrared spectroscopic measurement (reflectance, interactance and transmission) were compared for their ability to non-destructively estimate harvest soluble solids content (SSC), density and internal flesh colour of the yellow-fleshed kiwifruit Actinidia chinensis. Interactance mode spectra provided the most accurate estimates of SSC, density and flesh colour. SSC was predicted with a standard error of prediction (SEP) of 90.80° Brix and with correlation coefficient R of 0.93. Whole-fruit densities were predicted with an SEP of 93.6 kg m and with an R of 0.74. Internal flesh hue angle was predicted with an SEP of 91.6° and with an R of 0.82. © 2000 Elsevier Science B.V.

Relative water content (RWC) in plants is one of the most important biochemical parameters and its deficiency limits efficiency of photosynthesis and crop productivity. The scientific reports on using spectroscopy in detecting drought stress for sesame plants are very rare. In this study, the possibility of identifying water stress in two sensitive (Naz-Takshakhe) and resistant (Yekta) genotype...
