Research article Winter frost and its effect on kauri (Agathis australis) seedlings.
I. L. Barton
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.
