Dwarf lilyturf (Ophiopogonjaponicus K.), used as a weed-suppressing cover crop and a medicinal plant, was suggested to be a promising natural herbicide to control weeds in the rice field through its allelopathic potential. Allelopathic chemicals from the dwarf lilyturf were identified and their growth-inhibiting effects on two major weeds in the rice field in Japan were examined. High pressure liquid chromatograph (HPLC) analysis showed the existence of at least six allelopathic chemicals, viz., salicylic acid, syringic acid, syringaldehyde, vanillic acid, p-hydroxybenzoic acid and sinapic acid in dwarf lilyturf plant. The chemical detected at the highest concentration was salicylic acid (251.04 μg g^<-1>), which occupied more than half of total allelopathic chemicals detected (317.16 μg g^<-1>), followed by syringic acid (37.30 μg g^<-1>), syringaldehyde(13.30 μg g^<-1>) and sinapic acid (11.03 μg g^<-1>). The chemicals detected at the lowest concentration was vanillic acid (1.69 μg g^<-1>). Salicylic acid displayed the most inhibitory effects on germination and growth of both barnyardgrass (Echinochloa crusgalli L.) and monchoria (Monochoria vaginalis P.). This compound might play a key role in dwarf lilyturf allelopathy.

Four higher plants, namely glory bowers (Clerodendrum trichotomum L.), jimsonweed (Datura stramonium L.), beggarweed (Desmodium triflorum L.) and Chinaberry (Melia azedarach L.), with the strong allelopathic potential among 19 allelopathic species from Southeast Asia, were tested for their effects on weed emergence in paddy soil and field. In a greenhouse experiment, D. stramonium, D. triflorum and M. azedarach exhibited similar inhibitory magnitude at 1 t ha-1 achieving more than 90 % weed control. C. trichotomum achieved about 70 % weed reduction at 2 t ha-1. In paddy fields, D. triflorum was the most promising material for weed control and attained the highest rice yield among treatments, at the concentration of 2 t ha-1, whereas the inhibition of D. stramonium and M. azedarach was weakened in the greenhouse. No injury of rice plants was observed. These plants might be used as natural herbicides to reduce the dependence on synthetic herbicides.

Acidic fractions of the extracts from the three alfalfa cultivars Batasu, Rasen, and Yuba exhibited a varietial difference in the inhibitory effect on hypocotyls and radicle growth of alfalfa (cv. Nasuwakaba) and rice (cv. Koshihikari) seedlings. The extract from Rasen possessed the strongest inhibitory activity, and that of Batasu was the lowest. In a TLC bioassay with lettuce seedlings, inhibitory zones of the extracts were located at an Rf value of 0.6-0.8, and maximum exhibitory zones at Rfs of 0.7-0.8. However, the extracts of Rasen and Yuba contained an additional inhibitory zone at Rf of 0.1-0.2. Inhibitory zones were analyzed by HPLC. Eight phenolic compounds were identified in the extracts from Rasen and Batasu, and six compounds in that from Yuba. However, the content of these phenolic compounds varied with the cultivar. The content of each phenolic compound was the highest in Rasen, followed by Yuba and Batasu, although the content of p-hydroxybenzoic acid was equivalent in all cultivars. We suppose that the degree of inhibitory exhibition of allelopathy may be related to the presence and concentrations of allelochemicals (phenolic compounds), however, the allelopathic activity of the plant might be determined by interactions of all these compounds, not just a single chemical.

Allelopathic potential of velvetbean (Mucuna pruriens (L.) DC. Var. utilis) cultivated in temperate zone of Southern Kyusyu Island was studied. Furthermore, effects of L-3,4-dihydroxyphenylalanine (L-DOPA), which has known as a allelochemical of the plants, on the initial growth of sweet corn (Zea mays L.) and sweet pepper (Capsicum annuum L.) were evaluated. On the substitutive design experiment in upland field, the growth of sweet corn was promoted under the mixed planting with velvetbean, as reported on the previous studies. However, the effect on the growth of sweet pepper was not confirmed. These results were the same as those of container experiment were, and the dry weights of shoot and root of sweet corn increased in the mixed planting with velvetbean. The initial growth of sweet corn planted in the upland soil incorporated with the lower concentrations of L-DOPA was better, especially in the lengths of organs, such as second leaves and totals of crown roots, than that without L-DOPA (control), whereas there was no or negative effect of the higher concentrations on the growth and the lengths were almost the same or became shorter than those of untreated control. In sweet pepper, regardless of whether the concentration of L-DOPA was low or high, the lengths of organs, such as cotyledon, hypocotyl, tap root and total of crown roots, became longer than those of control, and the promotive effect of the initial growth was confirmed.
