“…In this study, the mean of radicle elongation percentage for 10 mg treatment was 69.5%. The means of radicle elongation percentage for some previous studies were in the range of 60.4% to 71.5% [2,[12][13][14]. The mean of radicle elongation percentage for this study was also found in the same range as some other previous studies.…”

“…These plants could potentially contain some chemical compounds, which affected the growth of lettuce seedling upon their release from dry plant samples into the agar medium. In other related studies, the compounds released from the donor plants were responsible for the plant growth inhibitory effect [4,6,11,14,15]. In this section, the chemical information of some previous research and a general introduction of the species with significant plant growth inhibitory potentials will be discussed.…”

“…Medicinal plants are used widely in folk medicine and essential commercial products in Turkey and can also be used as resource material for research in allelopathy. Bioactive compounds with medicinal properties could act as allelochemicals, and medicinal plants showed relatively strong allelopathic activity [2,[12][13][14]46,67,68]. Many potent allelochemicals have been isolated from medicinal plants in recent years [30,31,[69][70][71].…”

“…The method is a reliable, sensitive and less time-consuming bioassay method [2,12,[15][16][17]72,73]. It has been used primarily for the screening of medicinal plants [2,[12][13][14]68]. A dry sample of 10 or 50 mg was placed into six-well multi-dish plastic plate (35 mm × 18 mm, Thermo Fisher Scientific Inc., Suzhou, China).…”

“…The screening of a large number of plants by bioassay might be the first significant step in the investigation of related allelochemicals and their application in weed management. The sandwich method was developed to determine the allelopathic activity through plant leachates [2,12] and has been widely used [2,[12][13][14]. The method is reliable and less time-consuming under laboratory conditions that could be used in extensive screening in the identification of potential allelopathic species [2,12,[15][16][17].…”

Turkey has one of the richest plant diversities in the Mediterranean region. In the current literature, no broad screening has been conducted on the potential allelopathy of plants from Turkey. This study aimed to evaluate the allelopathic activity of a large number of plants from Turkey for the first time and to determine the species with significant plant growth inhibitory potentials by bioassay. Dried samples of different plant parts were collected from local herbalists. The sandwich method was used to evaluate the potential allelopathy of 126 medicinal plants belonging to 55 families. The results of lettuce radicle and hypocotyl growth for 10 and 50 mg sample treatment conformed to normal distribution. Significant inhibition on lettuce radicle elongation with 10 mg sample was observed in 40 species, out of which 27 species showed over 50% inhibitory activity. The results suggested that these species could contain potential inhibitory compounds against lettuce radicle or hypocotyl growth. The calyxes of Hibiscus sabdariffa (3.2% of control) and the seeds of Prunus dulcis (5.7% of control) showed the most potent growth inhibitory activity on lettuce radicle elongation. The potential plant growth inhibitory effects of these plants, together with the fruits of Rhus coriaria and seeds of Prunus mahaleb, have been reported in this study for the first time. All these plants are medicinal, and the results hereby presented provide essential information about the allelopathic effects of medicinal plants from Turkey.

Seeds express various germination behaviors in response to competitor plants. However, germination behaviors in response to facilitator plants are not yet well understood. Rumex obtusifolius seedlings usually appear on the ground near adult conspecific plants, and their survival rate under the canopy of adult conspecifics is higher than that outside the canopy, indicating that adult R. obtusifolius plants facilitate their seedling establishments. We hypothesized that emergence of R. obtusifolius seedlings is promoted by cues from adult conspecifics, but emergence of heterospecific seedlings is not. To test this, we investigated emergence responses of seedlings of R. obtusifolius and three other species that grow with R. obtusifolius in the presence of R. obtusifolius leaf phytochemicals. Emergence of R. obtusifolius seedlings was promoted by the presence of R. obtusifolius leaves. In contrast, emergence of other species seedlings was not promoted by R. obtusifolius leaves. We conclude that germination of R. obtusifolius seeds is facilitated in the presence of conspecifics, via water-soluble chemical exposure, and that recognizing these chemicals has adaptive value.
