dc.description.abstract	Seedlings of Metrosideros were capable of net accumulation of dry matter at photon flux densities as low as 13 umol m-2 s-1 PAR (about 0.6 percent sunlight), when grown under a 12-hour day1ength at 20° or 25°C for over 4 months. Seedlings became adapted to shade at low levels of PAR by an increased leafiness of the plant (expressed as the leaf area ratio). This increased leafiness was brought about by a marked reduction in leaf thickness rather than by an increase in the proportion of assimilates distributed to leaves.	en_US
