Summary The specificity of zinc accumulation by the first pod ofPisum sativum, variety Alaska, from the leaf in whose axil this pod is borne has been demonstrated. The secondpod receives a relatively insignificant amount of this transported zinc. The distribution pattern is somewhat similar to that previously found for phosphorus but differs in that zinc is translocated from the first bloom-node leaf 2 days prior to anthesis. At this stage no phosphorus is being translocated from this leaf. The preferential accumulation of zinc by the first pod reaches a maximum about 5 days after full bloom and the magnitude of this accumulation, relative to the aerial vegetative parts of the plant, remains essentially constant as the pod approaches maturity. The zinc accumulated by the ovules increases gradually beginning at about the 5th day after full bloom and is accompanied by a decrease in zinc retained by the carpel.
