Redistribution of 45ca in Trifolium Subterranevm L. and Antirrhinum Majus L.

Abstract

Injection of non·radioactive calcium into leaf 3 of normal· or low-calcium T. 8ubterraneum plants immediately after transfer to tracer-free solutions caused changes in the distribution of 450a in the low-calcium plants only. In these plants the mean 450a concentration in the laminae of all leaves was appreciably increased as a result of the influx of 450a from the petioles.
