Sammendrag
For many fruit crops, the colour of the fruit outwardly defines its eating quality. Fruit
pigments provide reproductive advantage for the plant as well as providing
protection against unfavourable environmental conditions and pathogens. For
consumers these colours are considered attractive and provide many of the dietary
benefits derived from fruits. In the majority of species, the main pigments are either
carotenoids and/or anthocyanins. They are produced in the fruit as part of the
ripening process, orchestrated by phytohormones and an ensuing transcriptional
cascade, culminating in pigment biosynthesis. Whilst this is a controlled developmental process, the production of pigments is also attuned to environmental
conditions such as light quantity and quality, availability of water and ambient
temperature. If these factors intensify to stress levels, fruit tissues respond by
increasing (or ceasing) pigment production. In many cases, if the stress is not severe,
this can have a positive outcome for fruit quality. Here, we focus on the principal
environmental factors (light, temperature and water) that can influence fruit colour.
