Influence of Illumination on the Synthesis of Leuco-Anthocyanins in Leaves


RECENTLY, Phillips1 suggested that the controlling factor in lignification in home-grown ash (Fraxinus excelsior) is the illumination received by the leaves. A coppice shoot of ash was hooded at various times during the growing season, and when sections of the stem were afterwards examined, it was found that poor lignification (in the botanical sense) coincided with the periods of shading.
