    Description

    The technique of growing tree seedlings in plastic greenhouses is being evaluated for red pine, jack pine, white spruce, and yellow birch at the Chittenden Nursery in northern Lower Michigan. Both a long growing season and a normal-length growing season in plastic greenhouses were compared with standard outdoor nursery beds (control). First-year results showed that germination and survival of red pine and jack pine were significantly higher in the greenhouses than in the control. Also, for red pine, the long growing season was superior to the other greenhouse treatments and the control. Results with white spruce and yellow birch were variable and differences between greenhouse treatments and the control were not statistically significant.
