In the original article, there was a mistake in the legend for Table 2 as published. Osmotic potential as demonstrated in the equation in the material and methods is the negative value. The correct legend appears below.
Table 2.
Osmotic potential (−ΨS) in Calotropis procera during drought and rainy seasons (2012 and 2013) in semi-arid and seacoast regions (n = 4 ± SE).
| Location | Season | Year | –ΨS (MPa) |
|---|---|---|---|
| Semiarid | Drought | 2012 | 1.33 ± 0.03 AB |
| 2013 | 1.41 ± 0.02 B | ||
| Rainy | 2012 | 1.34 ± 0.04 AB | |
| 2013 | 1.22 ± 0.03 A | ||
| Seacoast | Drought | 2012 | 1.07 ± 0.03 NS |
| 2013 | 1.14 ± 0.03 | ||
| Rainy | 2012 | 1.18 ± 0.02 | |
| 2013 | 1.20 ± 0.04 |
Means followed by different letters are significantly different according to the Student-Newman-Keuls test (P < 0.05).

The fractionation of the sugars was removed due to duplicate results, probably caused by contamination of the samples. However, the presentation of soluble sugars and starch allows to maintain the same discussion together with the other results.
In the original article, there was a mistake in the legend for Figure 4 as published. The correct legend appears below.
With the removal of the fractionation of sugars, Figure 7 was changed, as the PCA is a synthesis of the analyzed variables.
Figure 4.
(A,B) soluble sugar (SS) and (C,D) starch in Calotropis procera under semiarid and seacoast environment in rainy and drought seasons of 2012 and 2013 (n = 4 ± S.E.). Values followed by different letters differ from each other by the Student Newman Keuls test (P < 0.05).
Figure 7.
Principal component analysis (PCA) including potential osmotic (Table 2), gas exchange (Figure 3), biochemistry (Figures 4, 5), oxidative stress (Figure 6), and nutrients (Figure S2) in Calotropis procera under semiarid and seacoast environment in rainy and drought seasons of 2012 and 2013. Vectors with values above 0.70 of correlation were represented.
In the original article, there was a mistake in the legend for Figure 7 as published. The correct legend appears below.
