AN AUTORADIOGRAPHIC STUDY OF THE DISTRIBUTION OF ¹⁴C LABELLED ASSIMILATES AT DIFFERENT STAGES OF DEVELOPMENT OF <i>OXALIS LATIFOLIA</i> H.B.K. AND <i>O. PES‐CAPRAE</i> L.

Abstract

Summary. An autoradiographic study of the distribution of 14 C‐labelled assimilates, derived from 14 CO 2 fed to the aerial parts, was made at ten different developmental stages of Oxalis latifolia H.B.K. and Oxalis pes‐caprae L. Changing patterns of distribution of labelled assimilates to the underground parts of both species were revealed. These patterns are discussed in the context of the timing of control by defoliation and by foliageapplied herbicides.
