Abstract: Winter frost tolerance of kauri (Agathis australis) seedlings from seven sites was determined by subjecting dormant cotyledonary and 18-month-seedlings to a series of simulated frosts ranging in intensity from -1 to —6°C.
Cotyledonary seedlings survived frosts down to -4°C, usually with some damage. A few badly damaged seedlings survived frosts of -6°C. Seedling origin does not appear to influence a seedling's ability to withstand frost damage.
