比较了3种可见-近红外光谱测量模式（反射、互作用和透射）对黄肉猕猴桃果实可溶性固形物含量（SSC）、密度和内部果肉颜色的无损检测能力。互导模式光谱提供了最准确的估计SSC，密度和肉色。预测SSC的标准预测误差（SEP）为+/-0.80白利糖度，相关系数R-2为0.93。全果密度预测SEP为+/- 3.6 kg m（-3），R-2为0.74。用+/- 1.6度的SEP和0.82的R-2预测内部肉色角。(C)2000 Elsevier Science B. V.保留所有权利。
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 +/- 0.80 degrees Brix and with correlation coefficient R-2 of 0.93. Whole-fruit densities were predicted with an SEP of +/- 3.6 kg m(-3) and with an R-2 of 0.74. Internal flesh hue angle was predicted with an SEP of +/- 1.6 degrees and with an R-2 of 0.82.
