Error in Figure/Table
In the original publication [1], there was a mistake in Figure 2 as published; it contained incorrect names for the cultivars.
The Correct Figure 2:
Figure 2.
Principal component analysis (PCA) of seven non-redundant variables of 30 almond scion–rootstock combinations. (A) Distribution of scion–rootstock combinations classified by rootstock choice as a categorical variable with the first two components (Dim1 and Dim2), with concentration ellipses for each rootstock; (B) Distribution of scion–rootstock combinations classified by cultivar choice as a categorical variable with the first two components (Dim1 and Dim2), with concentration ellipses for each cultivar; (C) Distribution of the seven non-redundant variables with the first two components (Dim1 and Dim2). Contribution of each parameter to the components is colored from blue to red. Data were collected from 2-year-old trees. Refer to Table 1 for abbreviations.
In the original publication, Tables 2–4 had a superscript “1” in the table foot which does not add any meaning, and therefore has been deleted. There was a mistake in Table 3 as published, it contained incorrect names for the parameters. The correct parameter names are: Nb_IN, Length, IN_L, d_Top, Nb_B, BbyIN, BbyL, B_NbAS, Nb_sB, Nb_mB, Nb_lB, Dist_B, Dist_Down, Dist_Up and Top_SO. The correct table is shown below this paragraph.
Table 3.
Pearson’s correlation coefficients of variables comparing 30 almond scion–rootstock combinations, classified by which aspect of almond tree architecture they affect and selected by rootstock influence. Refer to Table 1 for abbreviations.

Text Correction
There was an error in the original publication. We realized that our version had a typing error in the Material and Methods section: “Three categories of shoot length were used to describe branching frequency along the trunk; these categories were short (<10 mm), medium (10–20 mm) and long (>20 mm), denoted as Nb_sB, Nb_mB and Nb_lB, respectively”. This should read: “Three categories of shoot length were used to describe branching frequency along the trunk; these categories were short (<100 mm), medium (100–200 mm) and long (>200 mm), denoted as Nb_sB, Nb_mB and Nb_lB, respectively”. Same changes, therefore, have been made to Table 1.
Table 1.
Parameters used to quantify aspects of almond tree architecture and the corresponding formula if parameters were calculated from other traits. Data were measured on the primary growth axis (trunk) or axillary branches of 2-year-old almond trees for 30 scion–rootstock combinations.
