To further explore the mechanism behind the allelopathic effects of Flaveria bidentis, we investigated the allelopathic effects of water extracts from Flaveria bidentis leaves on three plants, Shanghai green, barnyard grass and wheat. The results showed that the water extracts inhibited the germination potential, germination rate, seedling height, root length, chlorophyll content, fresh weight and dry weight of the three plants, and increasing the extract concentration further increased the inhibitory effect. The allelopathic effects of the water extracts from Flaveria bidentis leaves on the three receptor plants differed in strength from strong to weak as follows: Shanghai green > barnyard grass > wheat. Thus, wheat had strong resistance to the allelopathic effects of Flaveria bidentis and could be planted in area where Flaveria bidentis occurs. The effect of the water extract from Flaveria bidentis leaves on the seed germination and seedling growth of barnyard grass was obvious; thus, this extract could be used for the biological control of barnyard grass.

“…Likewise, the residues of T. portulacastrum considerably diminished the sesame seed germination [25]. Melilotus indica showed a strong allelopathic effect on crop plants' germination and growth of seedlings due to the presence of various secondary metabolic compounds [28].Many other allelochemicals such as ferulic acid, chlorogenic acid, vanillic acid, 4-hydroxy-3-methoxy benzoic acid, gallic acid, caffeic acid, and p-coumaric acid have been reported to cause reticence of germination and as well as early growth [29]. The inhibitory phytotoxic effect of leaf, stem, fruit, and root extracts of T. portulacastrum may be owing to the failure of water absorption and hindrance of germination of seeds [30].…”

Weeds are one of the key threats to the natural and agricultural fields. Weeds pose severe losses in agricultural yield by procuring nutrients and releasing secondary metabolites. Therefore, weed management is crucial for securing quantity and quality of yield. Various strategies that are most commonly employed to weed control are mechanical, physical, chemical, and cultural. However, the best method to eradicate weeds is a biological approach. The herbicidal potential of plants that can produce allelochemicals is considered a major source of biological control.In crops, weed control through allelopathy is a beneficial and environment-friendly alternativeto traditional herbicides.The object of this study is to explore the allelopathic impact of Trianthema portulacastrum against the growth of weeds (Asphodelus tenuifolius and Convolvulusarvensis and wheat(Triticum aestivum). The experimentwas performed in the petri-plates to explore the effect of various concentrations (30%, 60%, and 100%) of root and shoot of T. portulacastrum and herbicide (Metafin Super 28.6% WDG) along with control (distilled water)on the seed germination and growth of the weeds and wheat. To meet up the objectives, various parameters (such as seed germination, root length, shoot length, and seedling dry weight)of tested species were estimated. Our results revealed that water extracts of T. portulacastrum significantly reducedthe growth parameterspossibility due to interference with various growth metabolic processes. We conclude thatwater extract of root and shootof T. portulacastrumcould be safer and more beneficial to minimize the weeds competition in the wheat field.

“…Germination of seeds of two selected crops was observed by checking emergence of radicle and therefore, number of germinated seeds was recorded, and germination percentages calculated while radicle and hypocotyl lengths were measured with a measuring tape after seven days. Seeds germination percentages for all treatments and the control were calculated by considering average of germinated seeds against the total number of seeds sown using the following formula (adopted from Mustafa et al 23 with some modifications):…”

Allelopathic effects of the donor plants are mostly regarded as harmful to target plants such as traditional crops. Traditional crops play pivotal role as staple food for rural communities and hence ensuring food security. Study of the allelopathic effects of Androstachys johnsonii Prain on the germination and growth of Zea mays L. and Vigna subterranea (L.) Verdc was conducted. Different plant leachates concentrations of 0.675%, 1.25%, 2.5% and 5% were prepared through serial dilutions. Germination bioassays were arranged in a complete randomized setup of three replicates for each treatment for seven days. Germination rates were calculated, radicle and hypocotyl lengths were also measured. Germination rates of Z. mays L. and V. subterranea (L.) Verdc. ranged from 50 - 100% and 18 - 76%, respectively. Significant differences of P< 0.005 were noticed from the germination rates of V. subterranea (L.) Verdc subjected to high concentrations of different extracts used. Statistically there was no significant differences between germination rates of Z. mays L. treated with all concentrations of leaf leachates against germination rates of the seeds treated with distilled water. Outstandingly, the germination rate and early growth of Z. mays L. were promoted by less concentrated extracts of leaf, root, stem bark and soil which then suggest future use of allelochemicals from Androstachys johnsonii Prain for promotion of maize plant productions. Based on the beneficial attributes of allelochemicals from Androstachys johnsonii on the germination and growth of Z. mays L., planting of Androstachys johnsonii Prain in maize fields is highly recommended.
