THE VEGETATION OF DUNE SLACKS AT NEWBOROUGH WARREN: III. PLANTAGO CORONOPUS.

The article presents a study on the ordination of Plantago coronopus in the vegetation of dune slacks at Newborough Warren in Anglesey, Wales, using pattern analysis technique of P. Greg-Smith. It states that the scale pattern shown by Plantago coronopus was related to microtopography. Results also showed that its poor performance in the dune slacks is attributed to low nitrogen and phosphorous status. It mentions that germination is retarded in the dark and with gain in soil depth. Also, there is no effect in germination when the seeds are chilled and, though there is no germination in 50% sea water, the high salt content indicates no considerable injury to the seeds.
