Hidden Changes In Douglas-Fir Seedlings Suggest Timing of Nursery Operations

The study focused on two main questions: First, when do Douglas-fir seedlings grow at Wind River Nursery:-- height growth is readily seen, but growth by stems and roots is more difficult to observe. Second, when and in what forms do food reserves accumulate in seedling tops and roots. As they grow, seedlings use carbohydrates, fats, and proteins for energy and structural material. When the photosynthetic machinery to make these materials is inadequate or shut down, the seedling must call upon its reserves. Knowing if and when these materials accumulate and when they are used most rapidly helps pinpoint proper timing for lifting and storage. Such information may be the key to increased seedling vigor.
