A study of seed germination and growth of three populations of Atriplex polycarpa under greenhouse conditions using water cultures showed it to be very tolerant to high concentrations of boron in the growth medium. Germination was not affected by boron. Growth varied among populations but was generally not reduced by up to 40 ppm boron in the culture solutions. High levels of boron had no effect on root/top ratio or percent water in the top growth. Although growth was somewhat reduced in 80 ppm boron, no vsible morphological changes occurred or toxicity symptoms appeared.
