Growth and dynamic modulus of elasticity of Pinus patula × Pinus tecunumanii hybrids in Mpumalanga, South Africa [PDF]

Southern Forests: a Journal of Forest Science, 2016
Field establishment of South Africa’s most important commercial pine species, Pinus patula, is severely hampered by the pitch canker fungus, Fusarium circinatum. Importantly, hybrids between P. patula and other pine species tolerant to the pitch canker fungus, such as P. tecunumanii and P. oocarpa, have been identified as an alternative planting stock.

EFFECT OF PLANT EXTRACTS AND GROWTH SUBSTRATES ON CONTROLLING DAMPING-OFF IN PINUS TECUNUMANII SEEDLINGS [PDF]

CERNE, 2016
ABSTRACT Damping-off is considered one of the most limiting phytosanitary problems in conifer seedling production because it may cause massive damage or total plant death in short time periods. This pathology is caused by a complex of microorganisms, the most common of which are Fusarium spp. and Rhizoctonia spp.

Effect of foliar fertilization and soil conditioners on the rooting of a hybrid of Pinus tecunumanii vs. Pinus caribaea var. honduransis

Advances in Forestry Science, 2022
As técnicas de produção de mudas via propagação vegetativa, constituem formas alternativas da reprodução sexuada (uso de sementes), no entanto, diversos fatores prejudicam sua utilização de forma abrangente, como por exemplo baixas taxas de enraizamento de algumas espécies.

Properties of a Laminated Wood Composite Produced with Thermomechanically Treated Veneers

Advances in Materials Science and Engineering, Volume 2016, Issue 1, 2016., 2016
The paper aimed at evaluating the properties of plywood made from thermomechanically treated wood veneers. Veneers from Amescla (Trattinnickia burseraefolia) wood were treated in a hydraulic press with electric resistance heating. Two temperature levels were applied, 140°C and 180°C, for 1 and 2 minutes with 2.7 N/mm2 of pressure. A total of 30 plywood

Assessment of the Effectiveness of Ectomycorrhizal Inocula to Promote Growth and Root Ectomycorrhizal Colonization in Pinus patula Seedlings Using the Most Probable Number Technique

Applied and Environmental Soil Science, Volume 2014, Issue 1, 2014., 2014
The aim of this study was to evaluate the response of Pinus patula seedlings to two inocula types: soil from a Pinus plantation (ES) and an in vitro produced inoculum (EM). The most probable number method (MPN) was used to quantify ectomycorrhizal propagule density (EPD) in both inocula in a 7‐order dilution series ranging from 100 (undiluted inoculum)
