TL;DR: The various aspects of anthocyanin induction and pigmentation presented here are compatible with, and support, the proposed general role of Anthocyanins as photoprotective light screens in vegetative tissues.

TL;DR: Exposed fruit of 'Rosemarieʼ blushed pear (Pyrus communis L.) displayed daily fl uctuations in color in re- sponse to temperature while color was more stable in other blushed and fully red cultivars.

TL;DR: Changes in activity of phenylalanine ammonia-lyase and UDPGalactose: flavonoid-3-o-glycosyltrans- ferase during the development of pear fruit and in response to cold fronts were assessed and related to changes in red color.

TL;DR: The endogenous and environmental regulation of red colour development in blushed and fully red pears is reviewed and the contribution of anthocyanin degradation to pear colour at harvest is discussed.

TL;DR: Though EC could be used to improve ‘Rosemarie’ fruit colour in warm production areas, its effect was relatively small compared to colour change in response to fluctuating temperature, and the increased risk of sunburn during system 'downtime’ highlights the requirement for a highly reliable system.
