Abstract
Geocarpy (i.e. flowering above ground and fruit development below ground) is a characteristic of all Arachis species, including groundnut (A. hypogaea L.). Pods of this crop must absorb calcium (Ca) directly from the soil because of poor phloem mobility of Ca, but little is known of the mechanisms of Ca uptake by pods. Pods of three groundnut lines, representing Virginia (high Ca requirement) and Spanish and Valencia (low Ca requirement) types, were grown in solution culture. The Ca concentration in the kernel increased with increase in Ca concentration (0 to 1000 μM) in the podding solution. Net influx of Ca was associated with a net efflux of K from the developing pods, the ratio of K efflux to Ca influx decreasing with increase in Ca in the podding solution
