“…However, the growth and productivity of cultured plants has sometimes been reduced by this incorporation. In the latter case, the reduction is partly attributed to the release of phytotoxic substances from the incorporated materials into the soil, resulting in the production and release of phytotoxic substances during decomposition of organic matter by microorganisms in the soil (Achhireddy & Singh 1984;Sato et al 1989;Chow & Lee 1991;Kitou & Yoshida 1998;Kitou & Okuno 1999;Kitou 1999;Laterra & Bazzalo 1999;Sene et al 2000;Pramanik et al 2001;Ismail & Chong 2002;Horimoto et al 2002;Shiraishi et al 2002). In these cases, the phytotoxic chemicals were sometimes identified as phenolic compounds (Chow & Lee 1991;Kitou & Okuno 1999;Sene et al 2000;Ismail & Chong 2002).…”

Allelopathy is the inhibitory or stimulatory effect of a plant (donor) on other plants (receivers) through the chemicals released from the donor plant to the environment, mostly into the soil. These chemicals may reach the receiver plants in various ways, including leaching from plant foliage, exudation from the roots, and decomposition of dead residue of the donor plants. However, allelopathy in soil is a complicated phenomenon that is affected by soil condition, growth condition of the donor and receiver plants and climatic condition. Allelochemicals in soil are adsorbed on soil solids, and metabolized by chemical and biological reactions during the movement in soil. This behavior is affected by various soil factors, such as soil texture, organic and inorganic matter, moisture and organisms, which affect the phytotoxic activity in soil. If an allelochemical can directly affect the growth of receiver plants in soil, then the allelochemical might be present in the soil water so that it is directly available for absorption by the plant. Thus, it is suggested the concentration of an allelochemical in soil water is a dominant factor directly determining the phytotoxic activity in soil, and the concentration is controlled by soil factors that affect the behavior of adsorption, desorption and degradation in soil.

“…Actually, a great deal of effort has been put into the utilization of the allelopathic potential of plants for weed control instead of herbicide application (Fujii et al . 1991; Fujii 2001; Horimoto et al . 2002).…”

Keywords: allelopathy, arbor species, dish-pack method, sandwich method.Prefectural Green Center, Japan, from April -August in 2002 and 2003. Soon after the fresh leaves were collected, they were used for the experiment. Sandwich methodIn order to search for leaching substances from leaves, the sandwich method originally developed by Fujii et al. (2003) was revised and employed. For bioassay, a 12-well, multidish plate (3.66 cm 2 area per dish; Techno Plastic Product, Trasadingen, Switzerland) was used instead of a 6-well, multidish plate, as described by Fujii et al. (2003). The revised method is more convenient than the original one in order to screen a large number of samples without decreasing the efficacy. Then, 50 mg of each type of cut leaf were spread in each dish and 1 mL of 0.5% (w/v) agar solution cooled to 50∞C was added to each dish by a callus pipette (Iwaki & Co., Tokyo, Japan). After the leaves were fixed in the agar gel, 3 mL of agar solution were added and the mixture was allowed to harden. Five lettuce seeds (Lactuca sativa cv. Great Lakes 366) per dish were sown on the surface of agar. Each plate was covered with aluminum foil and kept in an incubator at 25∞C in the dark. Three days later, the lengths of the radicles and hypocotyls of the lettuce seedlings were measured. No leaves were put in the control treatment. Each experiment was triplicated. Dish-pack methodTo find out about the release of allelopathic substances by volatilization, a dish-pack method (Fujii et al. 2000) was employed for this purpose. A 6-well, multidish plate (9.03 cm 2 area of each dish; Techno Plastic Product, Trasadingen, Switzerland) was used for bioassay. Filter papers (34 mm, type 2; Toyo Roshi Kaisha, Tokyo, Japan) were placed in each dish, except one dish in the corner. After the addition of 0.7 mL of distilled water, seven seeds of lettuce (as described earlier) per dish were sown. Also, 2 g of freshly cut leaves were placed in a cor-

“…The allelopathic effect of plants is of particular interest in sustainable weed management. The species with significant plant growth inhibitory potentials are candidate plants for subsequent studies, which might be about isolation and identification of potent allelochemicals to find new compounds for bioherbicides or utilization of candidate species as mulching materials or ground cover crops [61][62][63][64][65][66].…”

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.
