Two types of the chlorophyll mutant of Triticum manacaccum, albino and carotina, have been used as the experimental materials in the present investigations. The former contains no chlorophylls and carotinoids and the latter contains carotinoids and a little amount of chlorophylls under the normal condition. It has been shown that by the low temperature treatment the green pigment was accumulated in the basal portion of the leaves in the albino, but in the carotina the accumulation of chlorophylls occurred on the whole leaves under the higher temperature condition. Comparison of the pigment formation in the albino with that in the carotina suggests that the mutant gene block responsible for the albino or the carotina may be operative at the step before or after the common precursor X of both chlorophylland carotinoid in their biosynthetic pathway.
