A Germination Inhibitor and Root-Growth Retarder in Chou Moellier (Brassica oleracea var.)

Abstract

INVESTIGATIONS are being undertaken at this Station into local problems associated with the establishment of new pastures. Such pastures are commonly sown in the autumn following a summer crop of chou moellier (marrow stem kale), Brassica oleracea var. A frequent outcome of such sowings is that the grass components of the seeds mixture germinate and grow apparently normally, while the legume component may or may not germinate. If the seeds of the legume component (chiefly white clover) do germinate, and seedlings emerge, they frequently die off in four to six weeks.
