Soil Moisture Stress Induces Transplant Shock in Stored and Unstored 2 + 0 Douglas-Fir Seedlings of Varying Root Volumes
Transplant shock was induced by applying a range of soil water contents to unstored and cold-stored 2-yr-old (2 + 0) bareroot Douglas-fir seedlings graded by root volume. Moisture stress had the greatest influence on morphological characteristics that express transplant shock. Seedling terminal growth, stem diameter growth, and needle length increased dramatically with increased soil moisture content. In addition, number of needles per centimeter on the terminal greatly increased with increasing moisture stress. Under high moisture stress, seedlings with relatively high root volumes tended to exhibit early reduced growth, but later showed significantly increased overall growth regardless of soil water content. In every case, seedlings grown in the driest soil had the lowest dry weights and those grown in the most moist soil had the highest weights for all seedling components. Similarly, seedlings with the smallest initial root volumes had the lowest dry weights, and those with the largest root volumes had the highest weights. The results indicate that moisture stress is a cause of transplant shock, and that increased seedling root volume may enable seedlings to avoid shock following outplanting to a specific site. FOR.
