Raulí is one of the most emblematic tree species Chilean temperate forests. Due to high quality wood, this has been used for furniture and handicrafts manufacturing, which positioned raulí as important commercial timber in Chile. Currently, international market demands sustainable production system forest production, more specifically plantlets production. In regard, plant growth-promoting rhizobacteria (PGPR) inoculants may enhance growth survival nurseries, means an increase effectiveness...
Understanding the biology of pollen is necessary to optimize reproduction plants and successful implementation conservation breeding programs.In order have information on morphological characteristics viability in Nothofagus nervosa, male flowers trees established a clonal seed orchard were collected.Morphological characterization was carried out from observations under light microscope scanning electron microscope.Motic Images Plus 2.0 software used for measurements.Viability assessed by...
The crooked stems of some individuals radiata pine ( Pinus D. Don) can hinder volume recovery and wood quality. To infer causes crookedness to learn how lean angle affects compression (CW) formation we studied 5-year-old trees in southern Chile. Eight initially straight eight were tethered angles 15° or 30° left untethered for 131 days (48 total). There no significant differences between the extent CW pretreatment relationship stem extent. Crooked trees, however, righted themselves more...
Density variation, being the timber longitudinally measured, and precision of spectroscopy near infrared (NIR) were evaluated to predict density pulp yield in two Eucalyptus globulus clones.Furthermore, variability volume NIR predictions was four E. clones represented growth sites.Clones selected by means trials: 10 11 year old sites from Araucanía Region, Chile.From each ramet, shavings samples at breast height diameter (BHD) obtained predictions.Additionally, a subgroup ramets, chips all...
Long-term pollen storage is important so that producers and breeders may be able to utilise stored cross individuals bloom at different times or in places. The objective of the current study was determine moisture content optimal temperature for Nothofagus alpina (P. et E.) Oerst pollen. Pollen samples used this were obtained from established trees 'Huillilemu' clonal seed orchard, located commune San José de la Mariquina, southwestern Chile. extraction conducted by placing it a climatic...
Reproductive biology knowledge of species is essential for in situ conservation, propagation and breeding.Consequently, we describe the first detailed phenology Nothofagus alpina, mentioned until now only general terms, provide morphological description male female flowers.The study was conducted 2011 Clonal Seed Orchard "Huillilemu" located locality San José Mariquina, Region Los Ríos, Chile, at 23 meters altitude.Observations were made six clones orchard.The model proposed presents ten...
The potential production of pollen per plant is a good indicator fruit production.In this work the reproductive efficiency index, average flower and functional relationship between number anthers amount Nothofagus alpina were determined.The ratio viable seeds formed after manual pollination by natural was calculated.The total grains estimated direct counting.The index at an 0.19.It found that anther varied among individuals years.Pollen 85,703 in 2011 117,975 2013.Low seed open could be due...
Understanding pathways of genetic information transfer from one generation to another is particularly important when open-pollinated seeds are collected for reforestation or enrichment native forests. Nothofagus alpina (Poepp. & Endl.) Oerst. temperate forests southern Chile and Argentina. However, lack knowledge its reproductive biology has hampered management in forest plantations conservation natural populations. Therefore, a clonal seed orchard N. was used analyse the mating system...
The main objective of this study was to assess the properties Nothofagus alpina wood from thinning that originates two sites with intensive silviculture and one similar a secondary growth forest, different soil, climatic conditions age. To achieve this, some mechanical, physical chemical-crystalline were characterized; studying differences pith bark between selected trees taken three plantations. Among studied plantation sites, there statistical in equilibrium moisture content, density...
Abies pinsapo es una especie en peligro de extinción originaria del Mediterráneo (España y Marruecos), se encuentra Chile como ornamental, pero Valdivia existe plantación experimental 42 años que permite conocer su desarrollo interés forestal. Los objetivos trabajo fueron caracterizar el rodal dasométricamente, analizar crecimiento diámetro, determinar la densidad básica madera sotobosque, mantillo arraigamiento. Mediante un censo los árboles midieron las variables diámetro normal basal...
