Redistribution of nutritive elements in a 'Gros Michel' banana plant.

The redistribution of nutritive elements in a vegetative banana plant was stud­ ied. For this purpose, silicon was used as an index element, under the presump­ tion that silicon is not redistributed within a plant. The results indicate that the nutritive elements N, S, P, K and Cu were strong­ ly redistributed from older to younger leaves, in contrast to Mg, CI, Fe and Zn, which were moderately redistributed. No redistribution could be found for Ca.
