Growth and Colonization of Western Redcedar by Vesicular-Arbuscular Mycorrhizae in Fumigated and Nonfumigated Nursery Beds

Western redcedar (Thuja plicata Donn ex D. Don) seedlings were grown in a bareroot nursery bed that had been fumigated with methyl bromide. Seedlings grown in fumigated beds were stunted and had purple foliage. Microscopic examination showed that roots from these seedlings were poorly colonized by mycorrhizae, and only by fine vesicular-arbuscular mycorrhizae. In contrast, roots from seedlings grown in non-fumigated beds had larger shoots and green foliage and were highly colonized by both fine and coarse vesicular-arbuscular mycorrhizae.
