Abstract
SUMMARY The influence of six substrates on Pinus ponderosa grown was studied in containers under greenhouse conditions. Treatments used were elaborated in a 1:1 proportion with an organic (coco fiber or Sphagnum peat moss) and an inorganic (pumice, vermiculite or perlite) compound. Different morphologic features were measured eight months later. The plants developed on vermiculite showed the best results. The combination of vermiculite with peat moss presented the greater size for all studied variables: stem diameter (4.9 cm), shoot height (25.4 cm), wet and dry weight of the whole plant (20.9 and 5.7 g), dry weight of the aerial and root portion (3.5 and 2.1 g), dry weight of the main root (0.7 g) and dry weigh of secondary roots (1.5 g). Three indexes were also evaluated in order to determine the plant quality. The substrates with vermiculite presented the best behavior for the different indexes.

Quality of maritime pine ( Pinus pinaster Ait.) seedlings using waste materials as nursery growing media

TL;DR: The use of peat as a growing media in forestry nurseries is decreasing due to high costs and environmental considerations as discussed by the authors, and diverse waste products are being used as organic amendments in certain soils before afforestation.

Native rhizobacteria as biocontrol agents of Heterobasidion annosum s.s. and Armillaria mellea infection of Pinus radiata

TL;DR: Biocontrol bacteria Pseudomonas fluorescens, Bacillus simplex and two different strains of Erwinia billingiae were isolated from the rhizosphere of a healthy tree located in a Pinus radiata plantation with high presence of fungal pathogens.

Cachaza como sustrato para la producción de plántula de tomate

TL;DR: In this article, six alternative growth media made of filter mud were evaluated, which suffered biological stabilization processes, alone or mixed with cattle manure and its subsequent use for the production of tomato seedling, in order to promote the use of other materials different from the peat.

Propagación asexual de uchuva (Physalis peruviana L.) en diferentes sustratos y a distintos niveles de auxina

TL;DR: The present study evaluated the effect of five concentrations of Indole Butyric Acid (IBA) and two substrates (peat moss, and a 1:1 v/v mixture of black soil and rice husks) on the rooting and growth of terminal cuttings from adult plants.

Planting-Stock Selection: Meeting Biological Needs and Operational Realities

R. D. Iverson
TL;DR: The tremendous variability in Northwest planting sites requires a variety of planting stock, so seedlings with tall shoots are better suited to brushy areas and where animal damage may be a problem; largecaliper seedlings will perform better where heat, insects, or physical bending are problems.
