“…Felker et al (1984) showed that various herbicides could control competing herbaceous plant growth and caused a fourfold increase in P. alba dry weight in field plots. Petersen et al (1986) found similar trends for the growth of another woody species. In addition, Bouteloua eriopoda (Torr.)…”

A competition experiment was carried out in a greenhouse with Schizachyrium scoparium (Michx.) Nash (little bluestem) and seedlings of Prosopis glandulosa Torr. (honey mesquite). The effect of S. scoparium density on the growth of P. glandulosa and the effect of a single P. glandulosa seedling on the growth of various densities of S. scoparium were examined. When P. glandulosa was grown with S. scoparium, there was a significant decrease in P. glandulosa above‐, belowground, and total dry weight at all S. scoparium densities tested. In contrast, P. glandulosa did not cause a significant reduction in S. scoparium dry weight. Root: shoot ratios for both P. glandulosa and S. scoparium increased almost three times from lowest to highest grass density. The number and length of flowering stalks of S. scoparium per plant decreased with increasing density. The presence of P. glandulosa caused a slight nonsignificant reduction of the number and length of S. scoparium flowering stalks. Establishment of P. glandulosa and other woody legumes would probably be low in high glass density and highly productive grasslands.

“…Knoop and Walker (1985) showed that competition with herbaceous plants caused a reduction in both Acacia tortilis and A. nilotica tree growth. Petersen, Ueckert, and Potter(1986) showed in a field study that Atriplex canescens (Pursh) Nutt. (fourwing saltbush) growth was reduced 60-80% when grown in proximity to several grasses.…”

“…Attributes of the ecotype have been described by Petersen et al (1987). Seedlings were grown from this bulk seed harvest in a greenhouse for 15 weeks, then 1,116 of the seedlings were transplanted into a stand of 'El Reno'sideoats grama in April 1982 (Petersen et al 1986). Growth rates of 511 seedlings that survived were recorded for 38 months after transplanting.…”

“…is widely used for rangeland reseeding and revegetation of disturbed sites because of its broad range of adaptation to soils and climate, winter leaf retention, and its potential to produce high-quality forage for livestock and wildlife. Success in establishing productive fourwing saltbush stands has been highly variable (Springfield 1970, Nord et al 1971, Aldon 1972, Petersen et al 1986, and failures have often been attributed to the detrimental impact of competing vegetation on seedling establishment and growth (Giunta et al 1975, Van Epps and McKell 1983, Geist and Edgerton 1984, Petersen et al 1986, Petersen et al 1990). Because the control of competing vegetation in fourwing saltbush plantings is usually neither practical nor economically feasible, selection for greater competitive ability appears to be an alternative strategy worthy of investigation.…”

Success in establishing fourwing saltbush [A triplex canescens (Pursh) Nutt.] is often limited by competition from associated vegetation. Fourwing saltbush is reported to have abundant natural genetic variation, hence selection for plant vigor or competitiveness may be an effective tool for cultivar improvement. We observed distinctive within-accession variation in the apparent ability of founving saltbush seedlings to tolerate competition from sideoats gama [Bouteloua curtipendula (Michx.) Torr.] in a 1982 field planting. Superior and inferior parental saltbush phenotypes in the field planting were cloned in 1984 by rooting stem cuttings, and the cloned propagules were transplanted into plots with or without competition to test the hypothesis that the competitiveness trait was genetically controlled. Survival and canopy development of superior and inferior clones planted at the same time in competition regimens were similar, suggesting that the parental phenotypes were not genetically different in their ability to tolerate competition. Differences observed in the parental phenotypes may have been environmentally induced, or genetic differences in the clonal material may have been masked by using rooted cuttings rather than seedlings, by excessive competitive pressure in the competition regimens utilized, or both. Clones from the 2 parental phenotypes performed similarly when transplanted into competitionfree regimens in November when growing conditions were favorable, but canopy development of clones from superior parental phenotypes exceeded that of those from inferior parental phenotypes when transplanted into competition-free regimens in April when growing conditions were poor.
