Effect of shading and fertilisation on the development of container-grown <i>Nothofagus glauca</i> seedlings, a threatened species from central Chile

Abstract

Nothofagus glauca is an endemic tree of the Mediterranean zone of Chile and is a threatened species. Currently, available information for the propagation and nursery cultivation of this species is conspicuously lacking. This study examined the effect of four levels of shade (18%, 35%, 65% and 80% with Raschel^® plastic net) and four rates of slow-release fertiliser (2.5, 5, 7.5, and 10 g l⁻¹ of Basacote^® Plus 9M) on container-grown seedlings after one growing season. Growth was significantly affected by shade and fertilisation. Seedlings grown under 18% or 35% shade were larger in diameter and had more roots than those grown under 80% shade and fertilisation with 2.5–5 g l⁻¹ of media were smaller than those fertilised with 7.5–10 g l⁻¹.
