Summary The absorption of Mn (III)-pyrophosphate complex by oat plants, cultured in a liquid medium with nutrient solutions, has been studied. The results indicate that the Mn supplied in this way is accumulated in the plant in a much more intense form. The root is the organ which through its Mn content best reflects the concentration of Mn in the medium in a directly proportional relationship, at the same time that the inflorescence is able to regulate the uptake of the element. It appears that the Mn (III)-pyrophosphate complex is less active compared with Mn (II) as ion, since with the same concentration in the plant less dry matter is produced. It is possible that it remains in the plant, at least partially, in the complex form. Nevertheless, the inflorescence does not distinguish between both forms of the element, as if in this organ they were rendered, or arrived in the same form. An antagonism between the Mn supplied and the Fe content in various parts of the plant is observed, especially when the Mn is added in the form of complex; except that, as noted above, the inflorescence and in this case also the roots does not distinguish between the two forms of the nutrient. re]19751218
