Since its publication, the authors of Lomax et al. (2009) have brought to our attention that there is an error in their article where the levels of UV-B radiation are reported incorrectly. In the Materials and Methods, subsection UV-B radiation, the UV-B radiation should read 9.96 kJ m−2 d−1 (and not 26 kJ m−2 d−1). The correct section is printed below.

We apologize to our readers for this mistake.

Plants were germinated and stratified as above, transferred into growth cabinets (Model P61700H/FM/RO-HQI; Sanyo Gallenkamp) and grown under a day:night regime of 8 : 16 h at 21 : 15°C, 60% RH, and vapour pressure deficit (VPD) 0.995 kPa. UV-B light was supplied by a bank of nine Sanolux UV high-pressure lamps (323 1219; Phillips, Guildford, UK) which increased UV-B (measured at 300 nm) radiation to 9.96 kJ m−2 d−1 at plant height over the entire daylength; in the control cabinet all UV-B radiation was excluded and UV-A radiation was reduced using specific UV-B and UV-A cut-off wavelength filters (226 Lee U.V.; Lee Filters, Andover, UK). UV-B levels were measured using a Sola-Check System (Solatell Ltd, Croydon, UK), cross-calibrated with a Macam spectroradiometer (SR9000-V7; Macam Photometrics Ltd, Livingston, UK).
