“…Because invasive plants had higher evolutionary rates in only two of the four species pairs, our results do not support the notion that invasive plants will show greater evolution of performance under climate change, particularly under global scenarios of warming and drought (Dai 2013). Still, other ecological factors influenced by climate change, for example, propagule pressure (Simberloff 2009) or allelopathic interactions (Medina-Villar et al 2020), could tip the balance in favor of invasive plants. Overall, our results with eight plant species and four distinct ecosystems might suggest that the general patterns of response in A max could be generalizable across plant species and ecosystems as the climate continues to warm and dry.…”

Climate change is expected to promote biological invasions. Invasive species often undergo adaptive evolution, but whether invasive species show greater evolutionary potential than their native counterparts under climate change has rarely been evaluated. We conducted experimental evolution trials comparing the evolution of physiological performance (light-saturated photosynthetic rate, A max ) of coexisting and closely related (1) invasive-native species pairs from Arid, Alpine, and Antarctic ecosystems, and (2) an invasive-naturalized species pair from a Mediterranean ecosystem differing in invasiveness. Experiments were conducted over three generations and under four environments of temperature and water availability resembling typical and climate change conditions in each ecosystem. A max increased across generations for most species. Invasive species from Arid, Alpine, and Antarctic ecosystems showed similar, greater, and lesser evolution of A max than their native counterparts, respectively. The Mediterranean invasive species showed greater evolution of A max than its naturalized congener. Similar patterns were observed in all four experimental environments for each ecosystem, suggesting that comparable responses may be expected under climate change scenarios. All study species showed a positive association between A max and reproductive output. Results suggest that invasive plants and their native (or naturalized) counterparts would show similar evolutionary responses of physiological performance to global warming and drought.

“…It shows the effect of different plant species on each other that may be stimulatory or inhibitory. Different environmental conditions directly or indirectly affect the allelopathic performance, and allelopathic interactions between crops, weeds and shrubs surviving together (Medina-Villar et al 2020). Allelochemicals are released as residues, exudates, and leachates by many plants from leaves, stems, roots, fruit and seeds.…”

Context Allelopathy is recognised as a potential technology to control weeds, and could also be a suitable approach for enhancement of crop yield. Aims The study was conducted to investigate the allelopathic role of Averrhoa carambola leaf extract on growth, anatomical and physiological features of three wheat lines, namely 3094, 7076 and A2011. Methods Three dilutions i.e. 0% (control), 15% and 30% of the leaf aqueous extract were applied at 15 day intervals (total five applications) on wheat lines until maturity. Key results All wheat lines showed differential behaviour to allelochemicals of A. carambola leaf extract. Increased root area was accompanied by a high proportion of storage parenchyma tissues and enlarged vascular bundles in line 3094. Disintegration of root cortical parenchyma and complete transformation of chlorenchyma into sclerenchyma in stem was recorded in all wheat lines, particularly at the highest concentration of leaf extract. Line 7076 showed very different behaviour, as it possessed a proportionally enlarged root cortex, enlarged stem vascular bundles and increased leaf thickness, primarily at the highest concentration of leaf extract. Line A2011 was relatively more sensitive, indicating a significant reduction (P < 0.05) in root and stem area and deformed leaves. Conclusions A low concentration (15%) of leaf extract promoted growth and development, whereas a higher concentration caused significant reduction in growth and anatomical attributes. Implications A lower dose of Averrhoa leaf extract promoted growth and development in all wheat lines, and hence can be used as a growth promoter. A higher concentration is important for eradicating unwanted plants.
