Laboratory experiments were conducted to determine juglone sensitivity of 16 species (Trifolium incarnatum, Coronilla varia, Vicia villosa, Lespedeza stipulacea, L. cuneata, Acer ginnala, Caragana arbor-escens, Elaegnus angustifolia, E. umbellata, Lonicera maackii, Quercus alba, Fraxinus americana, Liriodendron tulipifera, Alnus glutinosa, Pinus strobus, andP. sylvestris) being considered for mixed plantings withJugions nigra (black walnut). All species were sensitive to juglone, but seed… 
Allelopathic effects of leachates of Juglans regia L., Populus tremula L. and juglone on germination of temperate zone cultivated medicinal and aromatic plants
A pronounced species specificity was observed in tolerance of seeds and seedlings to the allelopathic effect of Populus and Juglans, and the aim would be to introduce them into agroforestry systems.
Effects of juglone concentration on growth in vitro ofFrankia ArI3 andRhizobium japonicum strain 71
It is revealed that a concentration of 10−3 M juglone absolutely inhibited the growth in vitro of aFrankia isolate from root nodules of red alder and ofRhizobium japonicum strain 71, and caution should be exercised in selecting nitrogen-fixing plants as nurse crops for black walnut.
Allelopathy in black walnut (Juglans nigraL.) alley cropping. II. Effects of juglone on hydroponically grown corn (Zea maysL.) and soybean (Glycine maxL. Merr.) growth and physiology
It is concluded that both corn and Soybean are sensitive to juglone and observed growth reductions in corn and soybean in black walnut alley cropping may partly be due tojuglone phytotoxicity.
Juglone reduces growth, nitrogenase activity, and root respiration of actinorhizal black alder seedlings
Results indicate that nitrogenase activity (acetylene reduction) of alders growing in 2 × 10−3 M juglone was reduced relative to alder without added jugl one after one day, and in 2× 10−6 M jug lone after five days, suggesting that this soil can readily detoxify juglones.
Herbicidal effects of juglone as an allelochemical
The study reveals that juglone is a potent inhibitor of growth of the weeds and therefore it can be evaluated as a herbicide for future weed management strategies.

Is Juglone the Only Naphthoquinone in Juglans regia L. with Allelopathic Effects?
We investigated whether juglone is the only allelochemical in a leaf extract from the walnut (Juglans regia L.). This was achieved through comparisons of the effects of pure juglone (1 mM, 100 μM, 10
Allelopathic Effects of some Medicinal Plants Extracts on Seed Germination and Growth of Common Weeds in Mashhad Area
The allelopathic effects of leaf extracts of Thymus vulgaris, Lavadula sp, Rosmarinus officinalis and Eucalyptus citriodora on seed germination and some growth characteristics of Solanum nigrum and Amaranthus retroflexus were investigated and there were significant different between the medicinal plants that used.
Effect of juglone on growthin vitro ofFrankia isolates and nodulation ofAlnus glutinosa in soil
In vitro growth (total protein content) of 5Frankia isolates was significantly inhibited at 10−4M juglone (5-hydroxy-1, 4-napthoquinone) concentration, but the degree of inhibition varied with theFrankia isolate, while an isolate fromPurshia tridentata (Pursh.) D.C. was most inhibited, displaying a dramatic decrease in growth and greatly altered morphology.
Evidence of Chemical Interactions on Germination and Seedling Growth in Annual Forage Species
Results suggested that grass exudates might affect seedling growth and development of some legume species owing to the inhibitory effects of allelochemicals found in grass live roots, but further research is necessary to verify the laboratory results under field conditions.


Autumn-Olive as a Nurse Plant for Black Walnut
Autumn-olive, Elaeagnus umbellata Thunb., is a promising species for planting in mixture with black walnut, Juglans nigra L. In five plantations in Missouri, Illinois, and Indiana, walnut grown in
It was concluded that the types of allelopathy which were tested by these bioassay results were not demonstrably effective under field conditions, that perhaps any species can be shown to have allelopathic properties in bioassays, and thatBioassays may, for many communities, have no ecological meaning.
Early Nodule Development in Myrica gale
Seedlings of Myrica gale were grown aeroponically and inoculated with suspensions prepared from mature nodules of M gale plants or with a homogenized preparation of a pure culture of the actinomycete
