Table 2 Chalkiness quantification of rice kernel samples with different chalkiness types

From: 3D Visualization and Volume-Based Quantification of Rice Chalkiness In Vivo by Using High Resolution Micro-CT

samples VG (mm3) VC (mm3) CD-3D (%) CD-2D (%) Significance between 3D and 2D methods
white-belly 9.96 0.54 5.4 18.8 **
white-core 7.91 0.42 5.3 15.6 **
white-whole 13.65 13.65 100 98.7 NS
white-back 14.06 0.79 5.6 9.9 **
  1. Note: VG (mm3) and VC (mm3) respectively represented the volume of grain and chalkiness detected by 3D method. CD-3D (%) and CD-2D (%) respectively represented the chalkiness degree detected by 3D method and 2D method. ** represented that the difference was extremely significant. NS represented “not significant”
