Analysis of intraspecific and interspecific interactions between the invasive exotic tree-of-heaven (Ailanthus altissima (Miller) Swingle) and the native black locust (Robinia pseudoacacia L.)
Invasive exotic plants can persist and successfully spread within ecosystems and negatively affect the recruitment of native species. The exotic invasive Ailanthus altissima and the native Robinia pseudoacacia are frequently found in disturbed sites and exhibit similar growth and reproductive …

Methods for Rapid Screening in Woody Plant Herbicide Development
… Five woody species were included in screenings: black locust, loblolly pine, red maple, sweetgum, and water oak. Two groups of seedlings were used in greenhouse screening: 1-year-old (1-0) and 2-year-old (2-0). Seedling age was not calendar years, but was the number of greenhouse growing seasons …
