Liw rüdh en delkyow, garednow,
flourys, losow ha frûtys ew dhort “anthocyanins” en killigow. Ma sagh bian e’n
cres a lies killik, leun a liw dowrek. En dowr trenk thew an liw rüdh (gwrewgh
pedery a eysyl ha bettys rüdh). Po nag eus dowr trenk thew an liw purpur po glas
(gwrewgh pedery adro dhe vellyon). Frûtys rüdh ew da gen edhyn – ma hebma o qweres
despersans has (war aga gòlvadnas po en aga theyl). Nebes bestes a gar debry
del glas – ma rüdh o cüdha an glas en nebes planjow ha rag hedna nag eus pecar
dynyans. Ma moy “anthocyanins” gwres en kidnyadh. Ma hebma o rei dhen liwyow
kidnyavek.
Red colour in leaves, stalks, flowers, vegetables
and fruits is due to “anthocyanins” in cells. There is a little sac in the
centre of many cells, full of watery colour. In acid the colour is red (think
of vinegar and beetroot). If there is no acid the colour is purple or blue (think
about violets). Birds like red fruits – this helps seed dispersal (on their
beaks or in their poo). Some animals love eating green leaves – red hides the
green in some plants and so there is not the same appeal. More anthocyanins are
made in autumn. This gives us autumnal colours.
