Nitrogen fertilization and mycorrhizae of balsam fir seedlings abies balsamea in natural stands


, : Nitrogen fertilization and mycorrhizae of balsam fir seedlings abies balsamea in natural stands. Naturaliste Canadien (Quebec) 105(6): 461-466

The short term and long term effects of urea fertilization on ectomycorrhizae of balsam fir seedlings growing in natural stands were determined. High rates of urea application significantly reduced the average number of ectomycorrhizae per seedlings, after 1 growing season. But 3 yr after fertilization, the average number of ectomycorrhizae and of long roots per seedling did not differ significantly from the control. The effect of different N sources and the mortality resulting from high applications of urea are discussed.

Isocyamus kogiae n. sp. is described from a pygmy sperm whale Kogia breviceps (De Blainville, 1838) stranded on Moreton Island, Queensland, Australia. It belongs in the genus Isocyamus because of its white appearance, epaulette-like processes at t...
