Abstract:
Usage of gibberellic acid inhibitors have been documented to increase seed harvest of grasses in the Pacific Northwest, but had not been evaluated for bermudagrass seed production in the low desert. Four rates of PalisadeTM (1-4 pts/acre)and three rates of Apogee7 (7-29 oz) were applied to 'Cheyenne' bermudagrass (Cynodon dactylon) to evaluate their effects on seed production. Treatments were applied just prior to inflorescence appearance, and lowest two rates of both chemistries included both single as well as double applications with second application approximately two weeks after experiment initiation. All PalisadeTM treatments significantly reduced plant heights and inflorescence heights, as did twice applied Apogee7 treatments for plant heights. Most PalisadeTM treatments also significantly reduced total inflorescence length as well as opened 'heads'. Data indicate that higher rates of both chemistries and especially PalisadeTM significantly reduced seeds per unit area. Of the treatments, only the lowest rate of Apogee7 (1 pt/acre) resulted in a numeric increase of seeds/acre compared with the untreated check.
