Summary

Two groundnut varieties, the small-seeded, early-maturing Natal Common and the large-seeded, late maturing ‘pops’-susceptible Makulu Red, were cultivated in nutrient solution, Application of calcium, labelled with 45Ca, to the roots and the fruit-medium respectively, showed that both varieties absorbed most of their seed-Ca from the fruit-medium. The translocation of calcium from the shells to the nuts was greater in the small-seeded variety Natal Common, which showed less susceptibility to ‘pops’. Calcium absorbed by pods and gynophores also migrated to a certain extent into the vegetative parts.
