Respective Species

Reed canarygrass, Phalaris arundinacea L., is one of the most productive, perennial cool-season grasses. It is found in humid and subhumid regions of the northern United States and southern Canada. Reed canarygrass plants with folded leaves were observed in a space-planted nursery. Morphological variants involving leaf folding or rolling have been studied in a number of grass species. None of these studies have investigated the anatomical differences between the folded leaf and more frequently occurring flat leaves in the respective species. The objective of this study was to investigate the histological differences between the folded and flat leaves. Upon sectioning, the flat leaf type was observed to have turgid bulliform cells, while those in the folded leaves were flaccid. And the folded leaves appeared to have a larger sclerenchymal layer in the extended bundle sheaths compared with the flat leaves. Incorporating the folded leaf genotype into a breeding program may allow the cultivation of reed canarygrass in more arid regions, and may improve the biofuel quality of a resulting cultivar.

Cool Season Grass

Abstract The ability to selectively control a specific cool-season grass growing in a mixed stand would offer great advantages to turfgrass managers. It is common for monostands of creeping bentgrass (Agrostis stolonifera) to become infested with annual bluegrass (Poa annua). Conversely, monostands of ‘True Putt’ creeping bluegrass (Poa annua var. reptans), a commercially available perennial biotype of Poa annua, often develop bentgrass infestations. The objective of this study was to evaluate the efficacy of various herbicides for the selective control of bentgrass with minimal injury to True Putt. Nine herbicide treatments were applied to 248 cm2 (38.4 in2) plugs maintained at 1.3 cm (0.51 in) in the greenhouse. The experiment was conducted twice during the winter of 2001–2002. Several ratings were made over the four week period on quality of bentgrass and creeping bluegrass and on reduction of bentgrass cover. Vantage, Image, Assure II, Fusilade II, Finale, and Balance Pro gave a minimum of 65% control with Vantage, Assure II, Fusilade II, and Finale achieving 100% control. However, Vantage was the only herbicide that provided complete control of bentgrass while causing no significant reduction in the quality of True Putt creeping bluegrass. Assure II and Fusilade II also provided complete control of bentgrass, but both had a negative impact on the quality of True Putt.
