A correction has been made to Results and Discussion, I_High induced light avoidance responses in green basil cultivars while purple basil remained ‘light-tolerant’, paragraph 1.

This sentence previously stated:

“As evident in Figure 5, undesirable morphological and anatomical leaf adaptations to I_High became clearly visible at the top canopy of the green-leafed cultivars cv. Anise, cv. Cinnamon and cv. Thai Magic during the last week of the trial period when PFDs exceeded an average of 300 µmol m^-2 s^-1 at canopy level (Table 2).”

A correction has been made to Results and Discussion, I_Low resulted in beneficial acclimation responses in green basil cultivars while purple basil performed insufficiently, paragraph 1.

This sentence previously stated:

“In contrast to the undesirable light-avoiding leaf adaptations and flower initiations detected under I_High (section 3.3), the light-orientated leaves of the green cultivars cv. Anise, cv. Cinnamon and cv. Thai Magic were fully expanded, thin and displayed typical green leaf colors under I_Low (Figure 5).”

The corrected sentence appears below:

Cinnamon and cv. Thai Magic were fully expanded, thin and displayed typical green leaf colors under I_Low (Figure 4).”

A correction has been made to Results and Discussion, I_Low resulted in beneficial acclimation responses in green basil cultivars while purple basil performed insufficiently, paragraph 2.

This sentence previously stated:

“The greater leaf sizes, the evenly distributed chloroplasts across the leaves of cv. Anise,

cv. Cinnamon and cv. Thai Magic (Figure 5) as well as the fact that marketability criteria were reached just 3-4 days later under I_Low (as described in section 3.2) are robust signs that very similar (beneficial) low light acclimation responses took place in the green cultivars investigated in our study.”

The corrected sentence appears below:

cv. Cinnamon and cv. Thai Magic (Figure 4) as well as the fact that marketability criteria were reached just 3-4 days later under I_Low (as described in section 3.2) are robust signs that very similar (beneficial) low light acclimation responses took place in the green cultivars investigated in our study.”

In the published article, Figure 4C is not referenced correctly in the text.

A correction has been made to Results and Discussion, I_Low resulted in beneficial acclimation responses in green basil cultivars while purple basil performed insufficiently, paragraph 3.

This sentence previously stated:

“To the contrary, the comparatively small leaf sizes (as evident in Figure 5C) and the slow development of cv. Dark Opal under I_Low (as evident by the great differences in plant height, number of developed leaf and branch pairs and thus biomass yields (Table 2 and Figures 4C, G, K, O) in comparison to I_High show clearly, that cv. Dark Opal was not able to adjust as well as its green basil counterparts to the given low light conditions.”

In the published article, Figures 5A-H are not referenced correctly in the text.

A correction has been made to Results and Discussion, Cultivar-dependent light intensity requirements under increasing light intensity conditions, paragraph 6.

This sentence previously stated:

“However, with the high-quality market-ready basils within 30-37 DAS (Figures 4A–H) detected under I_Low under increasing light intensities (between ~ 100 and 200 µmol m^-2 s^-1 (Table 2)) mostly below the lowest recommended constant light intensity of 180 µmol m^-2 s^-1 as recently reviewed by Sipos et al. (2021), the increasing light conditions applied in this study show that even with lower than previously assumed light requirements, high-quality basil productions under artificial light conditions are possible.”

The corrected sentence appears below:

In the published article, Figures 5Q-2 are not referenced correctly in the text.

A correction has been made to Results and Discussion, Cultivar-specific VOC concentrations change over time, paragraph 8.

This sentence previously stated:

“Different VOC accumulation patterns were observed between the investigated basil cultivars (Figures 4Q–S).”

The corrected sentence appears below:

“Different VOC accumulation patterns were observed between the investigated basil cultivars (Figures 5Q–S).”

A correction has been made to Results and Discussion, Cultivar-specific VOC concentrations change over time, paragraph 9.

This sentence previously stated:

“Within each cultivar, VOC concentrations generally did not differ between I_Low and I_High during each investigated time point, however, exceptions were observed in the cultivars ‘Dark Opal’ and ‘Thai Magic’ (Figures 4Q–S).”

The corrected sentence appears below:

“Within each cultivar, VOC concentrations generally did not differ between I_Low and I_High during each investigated time point, however, exceptions were observed in the cultivars ‘Dark Opal’ and ‘Thai Magic’ (Figures 5Q–S).”

In the published article, Figure 5S is not referenced correctly in the text.

A correction has been made to Results and Discussion, Cultivar-specific VOC concentrations change over time, paragraph 9.

This sentence previously stated:

“The significantly lower VOC concentration detected under I_Low in comparison to I_High at 14 DAS in ‘Dark Opal’ (Figure 4S) may be ascribed to the cultivars’ limited photosynthetic capabilities under low light conditions as discussed before in section 3.4 and hence, a presumably lower availability of photosynthates for secondary metabolism.”

The corrected sentence appears below:

“The significantly lower VOC concentration detected under I_Low in comparison to I_High at 14 DAS in ‘Dark Opa’ (Figure 5S) may be ascribed to the cultivars’ limited photosynthetic capabilities under low light conditions as discussed before in section 3.4 and hence, a presumably lower availability of photosynthates for secondary metabolism.”

In the published article, Figures 5T and 4D are not referenced correctly in the text.

A correction has been made to Results and Discussion, Cultivar-specific VOC concentrations change over time, paragraph 9.

This sentence previously stated:

“The slightly increased VOC concentration observed under I_Low in comparison to I_High at 35 DAS in cv. Thai Magic (Figure 4T) may indicate that this cultivar reaches its maximum VOC accumulation before flower buds arise (Figure 5D) after which VOC concentrations decrease – an accumulation pattern that has previously been described for the Ocimum basilicum cultivars ‘Rit-Sat’ and ‘Lengyel’ (Szabó & Bernáth, 2002) as well as for Ocimum ciliatum (Moghaddam et al., 2015).”

The corrected sentence appears below:

In the published article, Figures 5U–X are not referenced correctly in the text.

A correction has been made to Results and Discussion, Cultivar-specific VOC concentrations change over time, paragraph 10.

This sentence previously stated:

“When comparing total VOC yields produced at the end of the experiment (35 DAS), all cultivars had accumulated substantially greater VOC quantities under I_High than basils of the same age under I_Low due to the cultivars’ overall greater leaf biomasses accumulated under I_High (Table 2 and Figures 4U–X).”

The corrected sentence appears below:

“When comparing total VOC yields produced at the end of the experiment (35 DAS), all cultivars had accumulated substantially greater VOC quantities under I_High than basils of the same age under I_Low due to the cultivars’ overall greater leaf biomasses accumulated under I_High (Table 2 and Figures 5U–X).”

In the published article, there was an error in the legend for Table 9 Energy consumption at marketability of four Ocimum basilicum L. cultivars grown under two different light intensities as published. Figures 4A–H are incorrectly referenced.

The legend previously stated:

“DAS = days after sowing; FW = fresh weight; I_High = High light intensity; I_Low = Low light intensity; na = not available. ¹ Marketability is defined as plant height ≥ 15 cm and/or number of leaf pairs ≥ 4 [by our cooperation partners Oderbruch Müller, an organic nursery in Bad Freienwalde, Germany]; see also Figures 4A–H. ² Basil fresh weights [g pot^-1] at marketability were calculated using each cultivars’ polynomial biomass rates under each light treatment

(R² > 0.99).”

The corrected legend appears below:

“DAS = days after sowing; FW = fresh weight; I_High = High light intensity; I_Low = Low light intensity; na = not available. ¹ Marketability is defined as plant height ≥ 15 cm and/or number of leaf pairs ≥ 4 [by our cooperation partners Oderbruch Müller, an organic nursery in Bad Freienwalde, Germany]; see also Figures 5A–H. ² Basil fresh weights [g pot^-1] at marketability were calculated using each cultivars’ polynomial biomass rates under each light treatment
