Seedling growth of two pioneer tropical tree species in Competition: The role of arbuscular mycorrhizae

The effects of arbuscular mycorrhizae (AM) fungi on growth and survival of two pioneer tropical plant species were studied in a greenhouse experiment for 6 months. One, an early pioneer species (Heliocarpus appendiculatus Turcz., Tiliaceae) and the second, a late pioneer species (Stemmadenia donnell...

With AM infection, H. appendiculatus did not increase in growth, but showed greater survival in the absence of competition.

S. donnell-smithii with AM fungi infection showed better survival and increase in biomass, making it a better competitor than H. appendiculatus.2013-04-05T18:45:42Z2013-04-05T18:45:42Z2013-04-05T18:45:42Z2013-04-05T18:45:42Z2004info:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/articleGuadarrama, P; Álvarez-Sánchez, J; Briones, O (2004).
