“…Seed germination of mint, dandelion, and woad was promoted or inhibited in different degrees using fig tree leaf aqueous extract. The higher the concentration of the extract, the more intense their inhibitory effect on the seed germination of the recipient plants, which is in keeping with the formerly reported trend [38,39]. It has been reported that gradients in allelochemical concentrations have a strong promoting effect on plant growth [40,41].…”

Fig tree cultivation land resources are not fully utilized and introducing them into sustainable medicinal agroforestry systems can effectively achieve resource protection and reuse. Laboratory and pot experiments were applied to study the allelopathic effects of fig tree (Ficus carica L.) leaf aqueous extract at five mass concentrations of 8.3, 10.0, 12.5, 16.7, and 25.0 g/L on the morphological and physiological indexes of mint (Mentha haplocalyx Briq.), dandelion (Taraxacum mongolicum Hand.-Mazz.), and woad (Isatis indigotica Fort.). The results showed that mint had the best seed germination rate. The leaf aqueous extract at lower concentrations had a strong promoting effect on the biomass and photosynthetic parameters of mint, dandelion, and woad. With the increase in leaf aqueous extract concentration, the superoxide dismutase, peroxidase, and catalase activity of mint, dandelion, and woad increased initially and then decreased, but the malondialdehyde content increased. The synthetic allelopathic indexes of the three medicinal plants were in the following order: mint > woad > dandelion. Both the low and medium concentration extracts (8.3 g/L–12.5 g/L) showed an obvious promoting effect, while high concentrations exhibited distinct inhibiting effects. In conclusion, mint is the most suitable medicinal plant to be interplanted with fig trees for introduction into medicinal agroforestry systems.

“…Weeds are a major constraint to C. sativa production (Berti et al, 2016). C. sativa is considered to be very competitive against weeds with good stand establishment [ 22 , 96 ], due to its ability to produce and release secondary metabolites that prevent the growth of seedlings of neighboring plants [ 97 , 98 , 99 ]. However, the competitiveness of C. sativa for sunlight, nutrients, and water can be challenged by some weed species such as cheatgrass ( Bromus tectorum ), green foxtail ( Setaria viridis L.), and Russian thistle ( Salsola kali L.), among others [ 2 , 5 , 100 , 101 ].…”

“…C. sativa was also used as an intercrop with Jatropha integerrima in semi-arid regions of India with seed production improvements observed when grown alternatively with leguminous fodder crops [ 117 ]. Further exploration of the potential allelopathic effects of C. sativa in intercropping systems for weed suppression is needed [ 99 ].…”

Camelina sativa (L.) Crantz. is an annual oilseed crop within the Brassicaceae family. C. sativa has been grown since as early as 4000 BCE. In recent years, C. sativa received increased attention as a climate-resilient oilseed, seed meal, and biofuel (biodiesel and renewable or green diesel) crop. This renewed interest is reflected in the rapid rise in the number of peer-reviewed publications (>2300) containing “camelina” from 1997 to 2021. An overview of the origins of this ancient crop and its genetic diversity and its yield potential under hot and dry growing conditions is provided. The major biotic barriers that limit C. sativa production are summarized, including weed control, insect pests, and fungal, bacterial, and viral pathogens. Ecosystem services provided by C. sativa are also discussed. The profiles of seed oil and fatty acid composition and the many uses of seed meal and oil are discussed, including food, fodder, fuel, industrial, and medical benefits. Lastly, we outline strategies for improving this important and versatile crop to enhance its production globally in the face of a rapidly changing climate using molecular breeding, rhizosphere microbiota, genetic engineering, and genome editing approaches.

“…Plant allelopathy is a ubiquitous ecological mechanism in nature and is an important factor that affects seed germination and sometimes harms plant growth; however, as already mentioned, many allelopathic effects will depend on the extract concentration. The higher the concentration of an extract, the more intense its inhibitory effect on seed germination, regardless of the species [16,37,38].…”

The use of extracts derived from different plants has gained popularity as an alternative option to manage weeds and support phenological development in plants. One of the main problems facing agricultural production is the intensive application of chemical fertilizers that harm the environment. This study investigated the biostimulant effects of the aqueous extracts of Verbesinasphaerocephala and Verbesinafastigiata on the germination and growth of tomato (Solanum lycopersicum) and American cucumber (Cucumis sativus) seedlings. The aqueous extracts of both species of Verbesina were tested at concentrations of 0.5 and 1%. Seed germination and seedling development under nursery conditions were evaluated. The seed germination percentage was reduced in all treatments with the extracts of both Verbesina species when compared to that of the control treatment, which was considered an allelopathic effect. However, seedling growth in pots showed different behavior, with the extracts beneficially affecting certain agronomic variables, such as root and leaf length. The results suggest potential uses for V. sphaerocephala and V. fastigiata extracts, although a greater range of action may be experienced through the effects of certain molecules on weed growth. Additional studies with chemical approaches are necessary to better direct the uses and applications of Verbesina biomolecules, as they also functioned as growth promoters.
