EMERGENCE OF INTERMEDIATE WHEATGRASS LINES FROM FIVE DEPTHS OF SEEDING

Abstract

A study was conducted on 24 lines of Agropyron intermedium (Host.) Beauv. relating the size of seed to the depth from which emergence would occur. No consistent relationship was found to exist, although highly significant differences in emergence from depths of 2 inches and over did exist between lines. The results suggest that it might be worthwhile to use emergence ability from deep seedings as a selection criterion, but size of seed in itself appears to have no value.
