Abstract

The adhesives gum arabic, Methocel A-15, Pelgel, Solka Floe, and 2 experimental materials were evaluated for their effect on germination and early seedling growth of ‘Kentucky 31’ tall fescue (Festuca arundinacea Schreb.), and ‘Adelphi’ Kentucky bluegrass (Poa pratensis L.) and for their ability to retain a limestone seed coating. The adhesives did not adversely affect seed germination, turf quality, and early growth of seedlings of either species. Seedling growth of ‘Adelphi’, however, was enhanced by Methocel A-15 when compared to the control. Adhesive effectiveness for the retention of a limestone seed coating was in the order: Methocel A-15 > Pelgel > Solka Floe > AP-1 = AP-2.
