Phytase and acid phosphatase in the dwarf bean, Phaseolus vulgaris

67 sitol is drained away from the cotyledons and translocated to the growing parts of the plant. Whether inositol is translocated in the free state, or in some combined form, is not known at present, but the metabolic fate of inositol during the early development of the bean seedling seems to depend on the site to which translocation takes place. SUMMWARY 1. The inositol content of each anatomical part of the bean seedling has been determined, by microbiological assay, at each of six stages during the early development of the plant.
