Title: Botanical composition, light interception, and carbohydrate reserve status of grazed 'Florakirk' bermudagrass: Journal: Agronomy Journal; Authors: C. G. S. Pedreira, L. E. Sollenberger, and P. Mislevy; Date: 2000; Summary: Pedreira et al. determined persistence of the "Florakirk" cultivar of bermudagrass (Cynodon dactylon) at different stocking rates (stubble heights of 8-,16-,24-cm) and management regimes (rest period of 7, 21, 35 days) by measuring botanical composition, light interception, rhizome mass, and carbohydrate reserves before and after grazing. Light interception increased with stubble height and was less responsive to rest period, whereas rhizome mass declined with increasing stubble height and decreasing rest periods, suggesting a tolerance mechanism of increasing p ...; Agrovoc Control Words: Riparian zones, Rangelands, Wildlife; View more details about this article

Title: Effects of defoliation and competition on total nonstructural carbohydrates of spotted knapweed: Journal: Journal of Range Management; Authors: J. R. Lacey, K. M. Olson-Rutz, M. R. Haferkamp, and G. A. Kennett; Date: 1994; Summary: A short term greenhouse study examined spotted knapweed and bluebunch wheatgrass responde to competition (intra- and inter-specific), light and defoliation treatments. Collections of 405 mature plants of spotted knapweed and bluebunch wheatgrass were made in May. Three competition treatments (intra-specific spotted knapweed, and two levels of inter-specific spotted knapweed/bluebunch wheatgrass) were created in the greenhouse pots. Nine combinations of defoliation treatments (control, 75% removal at bolt stage of spotted knapweed and 50% removal of bluebunch wheatgrass at vegetative state, ...; Agrovoc Control Words: Weeds, Rangelands, Grazing; View more details about this article

Title: Clipping and long-term grazing effects on biomass and carbohydrate reserves of Indian ricegrass: Journal: Journal of Range Management; Authors: A. B. Orodho, and M. J. Trlica; Date: 1990; Summary: Long-term heavy grazing had little effect on root and crown biomass of Indian ricegrass (Oryzopsis hymenoides), nor did it significantly affect the total nonstructural carbohydrate (TNC) reserve levels or the seasonal cycle of reserves in this grass. Orodho and Trlica conclude that 50 years of protection from livestock use had not resulted in ecotypic differentiation in Indian ricegrass for these variables. Clipping reduced crown biomass more than root biomass and removal of 90% of aboveground biomass resulted in more than a 50% reduction in crown biomass and reserve car ...; Agrovoc Control Words: Riparian zones, Rangelands, Wildlife; View more details about this article

Title: Vigor of needleandthread and blue grama after short duration grazing: Journal: Journal of Range Management; Authors: P. E. Reece, R. P. Bode, and S. S. Waller; Date: 1988; Summary: Vigor of needleandthread (Stipa comata) and blue grama (Bouteloua gracilis) was measured by Reece et al., in a 7-pasture rotational grazing system after four years of short-duration grazing or three years of short-duration grazing and one year of rest, and four years of rest. Compared to ungrazed plants, blue grama plants grazed for four years had lower total nonstructural carbohydrates (TNC), while some blue grama plants that were rested for one year following three years of grazing and all needleandthread plants had TNC concentrations that were simi ...; Agrovoc Control Words: Riparian zones, Rangelands, Wildlife; View more details about this article

Title: Soluble carbohydrates, concurrent photosynthesis and efficiency in regrowth following defoliation: A field study with Agropyron species: Journal: Journal of Applied Ecology; Authors: J. H. Richards, and M. M. Caldwell; Date: 1985; Summary: Richards and Caldwell compare etiolated growth, carbohydrate pools and regrowth efficiency of Agropyron desertorum and Agropyron spicatum. A. desertorum consistently produced more regrowth in the absence of photosynthesis than A. spicatum, but a severe preclipping treatment did not significantly reduce etiolated regrowth in either species. Differences in regrowth between and within species were not correlated with crown non-structural carbohydrate concentrations, total pools, or amounts of utilized during regro ...; Agrovoc Control Words: Riparian zones, Rangelands, Wildlife; View more details about this article
