MicroCT was applied in a Pinus tree breeding study with three experiments.
This case study demonstrates the feasibility of using microCT scans as a partially non-destructive method in Pinus tree breeding programmes to confirm fertilisation and determine seed viability.
If the native forest could be restored, potentially by under-planting native Kunzea or Nothofagus trees before complete Pinus tree removal, it would likely be resistant to both exotic grass and Pinus invasion.
The Chakah Kanda (Kinnaur) study area features an observational plot on a slope along Kalpa Kanda, about 6 km from Kalpa in sub-alpine scrub with thickets of Salix sp. (50%) and Juniper sp. (20%) and scattered young Abies specatabilis and Pinus wallichiana trees at the well-defined tree-line.
Soil nitrogen (N) and phosphorus (P) concentrations were monitored in three pastures: a treeless pasture of bahiagrass (Paspalum notatum); a pasture of bahiagrass under 20-year-old slash pine (Pinus elliotti) trees (silvopasture); and a pasture of native vegetation under pine trees (native silvopasture).
A tree-ring δ18O chronology for the period 1828 2000 was developed from four Pinus merkusii trees, to find a reliable proxy for reconstructing precipitation in northwest Thailand.
Pinus radiata trees showing characteristic disease symptoms are shown in Figure 6.
Conifers (Pinus), deciduous trees (Betula, Salix, Quercus) and shrubs (Erica, Fabaceae) were identified.
The bark on Pinus radiata trees affected by red needle cast was examined for evidence of viable propagules of Phytophthora pluvialis and Phytophthora kernoviae deposited naturally on the prospective log surface.
Therefore, field trials involving application of phosphorous acid to mature Pinus radiata trees need to be carried out to determine an optimum dose for management of needle diseases in the field.
