Seedlings of Larix leptolepis, Picea abies, Pinus strobus, and P. sylvestris were established in a hydroponic system and installed in a growth chamber. The seedlings were grown for 8 to 10 weeks in a nutrient plus juglone solution at juglone concentrations ranging from 10-2 M to 10-10 M in order to determine the effects of juglone on each species. At concentrations of 10-2 M and 10-3 M, juglone was lethal to all species; Scotch pine and Japanese larch were also killed at a concentration of 10-4 M. Juglone caused no visible injury symptoms to white pine at concentrations of 10-6 M and less, and 10-5 M and less for the other species, but seedling growth was inhibited by solutions as dilute as 10-7 M. In contrast, solutions containing minute amounts of juglone apparently promoted seedling growth. For each species, at least one of the measured dry weight values for a treatment in the 10-8 M to 10-10 M juglone range exceeded those for the control plants. Forest Sci. 25:452-454.
