Phenotyping characters used to analyze growth and drought-related traits.
| Characters | Description |
|---|---|
| Shoot fresh weight (SFW) | The weight of the fresh shoot at the end of observation. |
| Root fresh weight (RFW) | The weight of the fresh root at the end of observation. |
| 2nd leaf length (LL2) | The length of the 2nd leaf from the tip of the plant. |
| 3rd leaf length (LL3) | The length of the 3rd leaf from the tip of the plant. |
| 4th leaf length (LL4) | The length of the 4thleaf from the tip of the plant. |
| Shoot area (SA) | The number of pixels scaled in cm on the shoot of the plant. |
| Green shoot area (GSA) | The number of pixels that have been scaled in cm in the shoot section has a hue value of 50. |
| Convex hull area (CT for top and CS for side) | The smallest area is covered by theouter contour of an object. |
| Object extend X (XT for top and XS for side) | The length of the X-axis of the rectangle covering the object is used to measure the width of the plant. |
| Object extend Y (YT for top and YS for side) | The length of the Y-axis of the rectangle covering the object is used to measure the height of the plant. |
| Number of leaves (NL) | The numberof leaf tips visible from above the plant. |
| Area growth rate (AGR) | Dividing the difference in shoot area between the drought stress treatment intervals by drought stress treatment time (days). |
| Red (R) | Color is measured by averaging the Red color value of all pixels in the shoot. RGB values are between 0 (no color) and 255 (maximum color). |
| Green (G) | Color is measured by averaging the Green color value of all pixels in the shoot. RGB values are between 0 (no color) and 255 (maximum color). |
| Blue (B) | Color is measured by averaging the Blue color value of all pixels in the shoot. RGB values are between 0 (no color) and 255 (maximum color). |
