“…At any particular time, the overall result of competition or facilitation is a cumulative effect. Therefore, the results from this study complement previous research [46], which showed that seedlings of R. pseudoacacia have a facilitative effect (due to the effect of nitrogen fixation on soil nitrogen availability) on the growth of A. altissima seedlings when the soil nutrient level may be low. In locations with equal numbers of both species, R. pseudoacacia will also facilitate the growth of A. altissima.…”

“…Consequently, A. altissima's ability to negatively affect R. pseudoacacia's growth rate in our study may be due to A. altissima's ability to better compete for below-ground resources, which was also found in greenhouse studies of seedlings [47]. Thus, the cause of inhibition by A. altissima on the much larger, above-ground R. pseudoacacia ought to be the result of either more effective below-ground competition or a negative effect of allelopathy on root growth and the nitrogen-fixing bacteria associated with R. pseudoacacia [46,48].…”

“…The facilitation may be enhanced at sites with low nitrogen availability [46], but not at high nutrient concentrations [47]. The intensity of the intraspecific competition for both species was highly correlated with plant size, which suggests that indirect competition for the same resources, such as light and nutrients, is the cause of intraspecific competition.…”

Abstract:The goal of this study was to discover the nature and intensity of the interaction between an exotic invader Ailanthus altissima (Mill.) Swingle and its coexisting native Robinia pseudoacacia L. and consider management implications. The study occurred in the Mid-Appalachian region of the eastern United States. Ailanthus altissima can have a strong negative influence on community diversity and succession due to its allelopathic nature while R. pseudoacacia can have a positive effect on community diversity and succession because of its ability to fix nitrogen. How these trees interact and the influence of the interaction on succession will have important implications for forests in many regions of the world. An additive-replacement series common garden experiment was established to identify the type and extent of interactions between these trees over a three-year period. Both A. altissima and R. pseudoacacia grown in monoculture were inhibited by intraspecific competition. In the first year, A. altissima grown with R. pseudoacacia tended to be larger than A. altissima in monoculture, suggesting that R. pseudoacacia may facilitate the growth of A. altissima at the seedling stage. After the second year, R. pseudoacacia growth decreased as the proportion of coexisting A. altissima increased, indicating inhibition of R. pseudoacacia by A. altissima even though the R. pseudoacacia plants were much larger aboveground than the A. altissima plants. In early successional sites A. altissima should be removed, particularly in the presence of R. pseudoacacia in order to promote long-term community succession.

“…In order to break the dormancy of A. altissima seeds, different methods have been tested. Gibberellic acid [34,35], cold stratification [3,33,[36][37][38][39][40][41], wet or dry stratifications [42,43], and sulfuric acid or boiling water [33] have been applied to the seeds over different periods of time. From the results reported, cold stratification seems to give the highest germination rates.…”

Tree of Heaven (Ailanthus altissima (Mill.) Swingle) is a tree native to China which has invaded disturbed areas in many regions worldwide. Its presence endangers natural ecosystems by displacing native species, modifying habitats, changing community structures, and affecting ecosystem processes. Its invasive nature is enhanced by its high ability to reproduce both vegetatively through root regrowth and sexually through seeds. Seeds, which are wind dispersed, are the main mechanism by which this species reaches new habitats. When they germinate and develop the root system, roots emit new shoots that contribute to a rapid increase in the tree density and the subsequent expansion of the population nearby. The contradictory results about the ecological requirements for seeds to germinate and their degree of dormancy and longevity indicate the complexity and difficulty of understanding the mechanisms that govern the biology and adaptability of this plant. The management of this weed aims at its eradication, with programs based on herbicide applications carried out by injecting the active ingredient directly to the trunk. But, not many active ingredients have shown total control, so new ones should be tested in order to increase the range of available herbicides. During the last few decades, some biological agents have been identified, but their efficacy in controlling the tree and their safety for the local flora have not yet been determined. A correct management strategy should take into account all these aspects in order to contain the expansion of this species and, ultimately, allow its eradication.

In this study, leaf N and P resorption levels of invasive Ailanthus altissima (Mill.) Swingle species were investigated. For this goal, leaf and soil samples were collected during the vegetation period. Thus, it was aimed to determine the amount of N and P elements from the leaves and their relationships with some soil properties. Forests in the Hendek district of Sakarya province which are affected by disturbance and species is gradually spread have been selected as the study area. Leaf and soil samples were collected every month during the vegetation period. The green and senescence periods of the species were determined by using N and P analyzes in the leaf samples taken and the resorption amounts were calculated. In addition, N and P contents, pH and electrical conductivity values of soil samples were measured and their relationships with resorption levels were explained. According to the findings, the N resorption ability of the species was found to be high and P resorption ability was close to the limit values. In addition, it was found that different soil properties (nutrient content, pH and electrical conductivity) did not adversely affect N and P resorption levels. As a result, A. altissima can be developed in areas with low nutrient content, different pH and electrical conductivity values, and so species can be used in plantation studies. Beside the abundance of litter with high nutrient content also enables the soil to enrich in N and P.
