An interesting budsport resulted from high-light stress. In this case, the young shoot has excessive anthocyanins (not accessory pigments such as carotenoids) and therefore it is often why a young newly developing leaf is redder than when it reaches its mature size. This pigment doesn’t involves in photosynthesis and merely act as a protect for tissues from photoinhibition, mainly excessive sunlight that can be damaging to some leaf tissues and this will be passed down. Sorry, no Chinese explanation. |
