✦ Synopsis
Abscisic acid (ABA) increased considerably in stem apices attached to Ricinus plants during a moisture stress but only slightly in stem apices which were detached and then allowed to lose water. A very marked rise in ABA also occurred in phloem-sap of moisture-stressed Ricinus plants. These results suggest that in apices of moisture-stressed plants the increased ABA does not arise iu situ but is translocated to the apex after synthesis in the mature leaves.
