Description of Work (possibly broken down into tasks), lead participant and role of participants and seconded staff

Leader of the WP: A. Martinez Meier, INTA

1.1     NIRS (calibration, portable, microSPIR) J.P. Charpentier, INRA.

1.1.1  Development of NIRS Calibration for microdensity, vulnerability to cavitation and ultrasonic method (J.P. Charpentier, INRA). The seconded staff will collect wood samples in Spain and in Argentina, bring them to INRA, then will be trained to use the NIRS and the microdensity equipment and will acquire the corresponding data and eventually develop the calibration models.

1.1.2  Test of portable NIRS (E. Merlo, MADERA PLUS). The portable NIRS will be used on standing trees in France (where some Spanish and Argentinean staff will be trained to use them), then used in Spain and in Argentina, in some cases with the assistance of other seconded staff. Data will be compared with laboratory NIR spectrum acquired on the same trees.

1.1.3  Test of micro NIRS (V. Segura, INRA). Seconded Argentinean staff will be trained to use the micro NIRS in France and will use it on French and Argentinean samples. Variation of micro NIRS signal will be studied.

1.2     Microdensity: comparison of X-ray and High Frequency methods (P. Rozenberg, INRA). Seconded Argentinean staff will be trained to use X-ray and High-Frequency microdensitometers and will acquire and compare profiles on Argentinean, Spanish and French plant material.

1.3     Test and validation of ultrasonic method (E. Merlo, MADERA PLUS). Two ultrasonic devices available in TOPWOOD (Spain and Argentina) will be used and compared in France, Spain and in Argentina, seconded staff will be trained to use them and data will be compared with other data collected on the same trees (microdensity and other wood properties)

Deliverables (brief description and month of delivery)

1. task 1.1.1 Development of NIRS calibration for microdensity variables in Eucalyptus, Pinus ponderosa and Austrocedrus chilensis (J.P. Charpentier, INRA)

2. task 1.1.1 NIRS calibration for vulnerability to cavitation in Eucalyptus globulus and vinimalis, Austrocedrus chilensis and Pseudotsuga menziesii (M.E. Fernandez, INTA)

3. task 1.1.2 portable NIRS, comparison of portable and laboratory NIRS with Populus, hybrid Pinus, Araucaria angustifolia and Pinus ponderosa, month 24 (E. Merlo, MADERA PLUS)

4. task 1.2 Acquisition of X-ray and HF microdensity profiles in Austrocedrus chilensis, Eucalyptus, Pinus ponderosa and Pseudotsuga menziesii, month 37 (A. Martinez Meier, INTA)

5. task 1.3 Acquisition of ultrasonic data on Pinus radiata, hybrid Pinus, Araucaria angustifolia and Eucalyptus, month 40 (E. Merlo, MADERA PLUS)

6. Training session “NIRS calibration into practice” (J.P. Charpentier, INRA)

7. Training session “X-ray microdensity into practice, from the sample collection to the profile acquisition with Windendro” (F. Millier, INRA)

8. Training session “Nondestructive measurement of wood quality on standing trees: the ultrasonic method” (E. Merlo, MADERA PLUS)
