Methodology For the selection of the markers, a reference population of 30 unrelated parents for each species of interest (Eucalyptus globulus and Pinus radiata) was used. In these populations, we tested 25 SSR for pinus and 38 SSR for eucalyptus and the best 12 markers were selected for each species. With the selected markers, a pattern or fingerprint of each operational clone was obtained, ou...

Colour changes, such as kiln brown stain, that develop in Pinus radiata boards during kiln drying can reduce the value of the final wood products and result in significant losses due to downgrade or waste of dried wood by removing the darkened surfaces. This study measured how colour developed in Pinus radiata sapwood boards under different drying schedules. The boards used in these experiments...

A dynamic kiln-wide wood drying model was developed previously to solve the integral form of the unsteady-state mass, momentum and energy balance equations in the air side. For the wood side, an empirical model, characteristic drying curve, for the internal moisture movement is used, which was obtained for low and medium temperature drying of Pinus radiata, with a medium velocity of 1.44.1 m s....

Greenhouse-cultured, container-grown seedlings of Aleppo pine (Pinus halepensis Mill.), radiata pine (Pinus radiata D. Don), and interior Douglas-fir (Pseudotsuga menziesii var. glauca (Beissn.) Franco) were cold acclimated and deacclimated in growth chambers over 24 weeks. Needle and root cold hardiness and root growth potential (RGP) were measured weekly. Root, needle and stem analyses for so...

Ensemble classifiers are being widely used for the classification of spectroscopic data. In this regard, the random forest (RF) ensemble has been successfully applied in an array of applications, and has proven to be robust in handling high dimensional data. More recently, several variants of the traditional RF algorithm including rotation forest (rotF) and oblique random forest (oRF) have been...

We compared the performance of mycorrhiza-inoculated and non-inoculated radiata pine (Pinus radiata D. Don) seedlings in two field studies. In the first study, above ground growth of 2-year-old container-grown trees was compared after planting in two areas that differed in water availability. Mycorrhizal inoculation significantly improved above ground growth in the 2 years after planting in bot...

Key Message Agrobacterium tumefaciens was used to transform radiata pine shoots and to efficiently produce stable genetically modified pine plants. Abstract Micropropagated shoot explants from Pinus radiata D. Don were used to produce stable transgenic plants by Agrobacterium tumefaciens–mediated transformation. Using this method any genotype that can be micropropagated could produce stable tra...

It has been generally considered that the incidence of graft incompatibility in Pinus is low compared with other genera. This paper cites an example of a sudden increase to more than 50% incompatibility in a 14-year-old seed orchard of Pinus radiata D. Don. The types of incompatibility present are examined and the implications for New Zealand's clonal seed orchard programme are discussed. INTRO...

The mineral nutrient requirements of Pinus taeda cells were explored using quantitative cell culture growth measurements. An appraisal was thereby made of the critical features of a novel and successful medium which was developed specifically for this gymnosperm using chemical composition data for developing seeds, and characterized by generally high concentration of all micronutrients, high ma...
