Techniques to Increase Survival of New Highway Plantings Using Mycorrhizal Inoculation

摘要

Effects of fertility and endomycorrhizal inoculation on growth of Liriodendron tulipifera L., Acer platanoides L., Forsythia x intermedia Zab., and Lolium perenne L. were determined. Plants were inoculated with endomycorrhizal Glomus fasciculatus and Glomus mosseae and grown in a greenhouse at three fertility levels (0, 2, or 4 g/l Nitrogen) of soil medium. A. platanoides, F. x intermedia, and L. perenne did not respond to mycorrhizal inoculation and grew best at 2 g/l N. Growth of L. tulipifera was increased by mycorrhizal development, and shoots were heaviest at 4 g/l N. Mycorrhizae did not enhance growth of unfertilized plants. The effects of temperature and endomycorrhizal inoculation on growth of L. perenne were determined.
