Abstract
ABSTRACT: The production of tree seedlings with high survival rate and growth is influenced by the substrate, which may be composed of biological and non-biological materials that help plant growth. The objective of this study was to evaluate the efficiency of a mycorrhizal inoculant on farm and the use of a potassic rock (phonolite) on growth and nutrition of Eucalyptus saligna Sm. and Schinus terebinthifolius Raddi under greenhouse conditions. Both species were assigned to three mycorrhizal treatments [no inoculated control [...]
Highlights
Reforestation includes planting of native and exotic woody species through human intervention and represented 7 % of the total area covered by forests in 2012 (FAO, 2012)
For S. terebinthifolius, plant height and SDM were significantly affected by phonolite, mycorrhizal inoculation, and the interaction factor, while stem diameter and RDM were significantly affected only by mycorrhizal inoculation and the interaction factor (Table 1)
Other parameters for E. saligna were significantly affected by the interaction factor or mycorrhizal inoculation
Summary
Reforestation includes planting of native and exotic woody species through human intervention and represented 7 % of the total area covered by forests in 2012 (FAO, 2012). This activity contributes to forest (e.g., wood) and non-forest products, such as carbon sequestration, rehabilitation of degraded environments, and protection of watershed and agricultural areas (Evans, 2009). To support this activity, it is necessary to produce high quality seedlings, especially those with high survival and growth rates (Ritchie, 1984). Addition of powdered rocks containing nutrients important for plant growth provides a better substrate for raising seedlings (Ramos et al, 2014)
