14. VARIABILIDAD GENÉTICA DEL CRECIMIENTO EN PROGENIES SELECTAS DE Pinus radiata
ABSTRACT Narrow sense heritability (h2), intra-class genetic correlations (Γ2IC) and variance components for height, diameter at breast height and stem volume of seven-year-old trees were investigated. Two progeny trials of Pinus radiata were planted in southern Chile and growth data obtained to estimate genetic variability. These trials included trees from

15. Produção de polpa kraft branqueada de Pinus tecunumanii (Eguiluz e Perry)
Foram avaliadas amostras de Pinus tecunumanii de (Eguiluz e Perry) com 12 anos de idade procedente da Colômbia, para produção de polpa de kraft branqueada. Produziram-se polpas kraft com número kappa 30±1, deslignificada com oxigênio e branqueada a 90% ISO por processo ECF. As polpas branqueadas foram produzidas em condições ótimas e avaliadas com r

16. Experimental determination of the effect of temperature and humidity on the development of colour in Pinus radiata
Experiments were undertaken to determine the effects of drying conditions (temperature and humidity) on the development of kiln brown stain in radiata pine during drying. Eight schedules were tested with temperatures ranging from 50°C to 120°C and relative humidity from 14% to 67%. The variables measured were moisture content, color expressed using the CIE

17. Patch-matrix interactions and bird species conservation in a plantation-dominated landscape in Australia
Conservation of wildlife and key ecological processes in production landscapes are essential for the achievement of ecologically sustainable natural resource use. Thus, investigations of wildlife response to landscape change have become critical. This thesis aims to obtain information useful for the better integration of wildlife conservation and wood produc

18. Modelling lucerne (Medicago sativa L.) crop response to light regimes in an agroforestry system
The general goal of this research was to understand the agronomic and physiological changes of a lucerne crop in distinct physical radiation environments and to verify the potential of lucerne to grow under shaded conditions. To achieve this, the research was conducted in four main steps: (i) firstly, experimental data collection in the field using two artif

20. Two Pine Endo-β-1,4-Glucanases Are Associated with Rapidly Growing Reproductive Structures
Two cDNA clones encoding endo-β-1,4-glucanases (EGases) were isolated from a radiata pine (Pinus radiata) cDNA library prepared from immature female strobili. The cDNAs PrCel1 (Pinus radiata cellulase 1) and PrCel2 encode proteins 509 and 515 amino acids in length, respectively, including putative signal peptides. Both proteins contain domains conserv

21. Chloroplast DNA Diversity among Trees, Populations and Species in the California Closed-Cone Pines (Pinus Radiata, Pinus Muricata and Pinus Attenuata)
The amount, distribution and mutational nature of chloroplast DNA polymorphisms were studied via analysis of restriction fragment length polymorphisms in three closely related species of conifers, the California closed-cone pines-knobcone pine: Pinus attenuata Lemm.; bishop pine: Pinus muricata D. Don; and Monterey pine: Pinus radiata D. Don. Genomic DNA fro

22. NEEDLY, a Pinus radiata ortholog of FLORICAULA/LEAFY genes, expressed in both reproductive and vegetative meristems
The LEAFY/FLORICAULA genes from Arabidopsis and Antirrhinum are necessary for normal flower development and play a key role in diverse angiosperm species. A homologue of these flower meristem-identity genes, NEEDLY (NLY), has been identified in Pinus radiata. Although the NLY protein shares extensive sequence similarity with its angiosperm counterparts, it i

23. Chloroplast genomes of two conifers lack a large inverted repeat and are extensively rearranged.
Chloroplast genomes of Douglas-fir [Pseudotsuga menziesii (Mirb.) Franco] and radiata (Monterey) pine [Pinus radiata D. Don], two conifers from the widespread Pinaceae, were mapped and their genomes were compared to other land plants. Douglas-fir and radiata pine lack the large (20-25 kilobases) inverted repeat that characterizes most land plants. To our kno

24. Genes Expressed in Pinus radiata Male Cones Include Homologs to Anther-Specific and Pathogenesis Response Genes1
We describe the isolation and characterization of 13 cDNA clones that are differentially expressed in male cones of Pinus radiata (D. Don). The transcripts of the 13 genes are expressed at different times between meiosis and microspore mitosis, timing that corresponds to a burst in tapetal activity in the developing anthers. In situ hybridization showed that
