Quantitative descriptors: |
CPA - Crown projection area: evaluated from the end of the first reproductive cycle of the plant. The CPA (in square metres) is determined using the following estimator:
CPA=[(CPAn+ CPAs)×(CPAe+CPAw)]2
|
CPAe - Eastern projection of the crown: evaluated from the end of the first reproductive cycle of the plant. The CPAe (in meters) is measured from the central region of the base of the stem to the maximum projection of the branch in an easterly direction. |
CPAn - Northern projection of the crown: evaluated from the end of the first reproductive cycle of the plant. The CPAn (in meters) is measured from the central region of the base of the stem to the maximum projection of the branch in a northerly direction. |
CPAs - Southern projection of the crown: evaluated from the end of the first reproductive cycle of the plant. The CPAs (in meters) is measured from the central region of the base of the stem to the maximum projection of the branch in a southerly direction. |
CPAw - Western projection of the crown: evaluated from the end of the first reproductive cycle of the plant. The CPAw (in meters) is measured from the central region of the base of the stem to the maximum projection of the branch in a westerly direction. |
DPH - Height of developed plants: assessed from the end of the first reproductive cycle of the plant. The DPH (in centimetres) is measured from the base of the stem (ground) to the upper end of the tallest branch. |
ILBI - Internode length of branches with an inflorescence: assessed from the first reproductive cycle of the plant. The ILBI (in centimetres) is determined from the mean length of the internodes measured on the three longest branches containing an inflorescence. Four internodes are measured on the median part of each branch with an inflorescence. For plants with erect architecture and no branches, the ILBI is given by the mean value of the four internodes on the median part of the stem, providing it contains an inflorescence. |
ILPB - Length of the internode of primary branches: assessed from the first reproductive cycle of the plant. The ILPB (in centimetres) is determinedby the mean length of the internodes measured on the three longest primary branches on the plant. Six internodes are measured on the median part of each primary branch. For plants with erect architecture and no branches, the ILPB is given by the mean value of the measurements of six internodes on the middle part of the stem. |
LBI - Length of branches with an inflorescence: evaluated from the first reproductive cycle of the plant. The LBI (in centimetres) is determined by the mean value of the length of the three longest branches containing an inflorescence, measured from the base of the branch close to the ground to its upper end. For plants with erect architecture and no branches, the LBI is given by the height of the plant, measured from the base of the stem close to the ground to the upper end of the single branch, providing the branch contains an inflorescence. |
LIA - Leaf insertion angle: evaluated at any stage during the development cycle of the plant. The LIA is determined by the mean value in degrees of the measurements of 10 fully developed leaves, measured between the leaf insertion (petiole) and the stem. |
LL - Leaf Length: assessed at any stage during the development cycle of the plant. LL (in centimetres) is determined from the mean length of 10 fully developed leaves per plant. |
LLWR - Leaf length-width ratio: assessed at any stage during the development cycle of the plant. The LLWR is determined from the ratio of leaf length (LL) to leaf width (LW). |
LPB - Length of the primary branches: Evaluated from the first reproductive cycle of the plant. The LPB (in centimetres) is determined from the mean length of the three longest primary branches, measured from the base of the branch close to the ground and its upper end. For plants with erect architecture and no branches, the LPB is given by the height of the plant, measured from the base of the stem close to the ground to its upper end. |
LW - Leaf Width: assessed at any stage during the development cycle of the plant. The LW (in centimetres) is determined from the mean width of 10 fully developed leaves per plant. |
MPL - Mean length of the petiole: assessed at any stage during the development cycle of the plant. The MPL (in centimetres) is determined from the mean value of the length of the petiole in 10 fully developed leaves per plant. |
NBI - Number of branches with an inflorescence: evaluated from the first reproductive cycle of the plant. The NBI is determined by quantifying the total number of branches that have at least one inflorescence. |
NLL - Number of lobes per leaf: assessed at any stage during the development cycle of the plant. The NLL is obtained by quantifying the lobes in 10 fully developed leaves per plant. |
STD - Stem diameter: Assessed from the first reproductive cycle of the plant. The STD (in centimetres) is measured in the region of the collar at a maximum height of 10 cm from the base of the stem in the ground. |
TNB - Total number of branches: assessed at any stage during the development cycle of the plant. The TNB is determined by quantifying the total number of branches on the plant. |
