Root Regeneration and Early Growth of Red Oak Seedlings: Influence of Soil Temperature
Abstract:One-year-old northern red oak (Quercus rubra) nursery stock was grown in a greenhouse at various day/night soil temperature regimes for 4 weeks. No single optimum soil temperature for root growth was evident, but roots grew well at constant 24°C, and some aspects of root growth decreased at 18 and 29°C. Shoot growth was good at 29° soil temperature but was greatly reduced below 18° even though air temperatures remained favorable. Seedling growth responded to the total daily degree hours of soil heat rather than to the differential between day and night temperature. In a second experiment, seedlings were pretreated, with roots at 24° and tops at 2°C. Seedlings pretreated 1 week grew more roots and shoots than did seedlings pretreated either 2 or 3 weeks, but none grew significantly better than untreated controls. Both pretreated and untreated seedlings responded similarly to soil temperature treatments. Forest Sci. 16:442-446.
