An initial observation shows the evident weaknesses of the plant. We then take samples indispensable for a complete analysis:

• Identification of diseases, parasites, deficiencies.
• Wood analyses: these generate a remarkably reliable history, whereby the risks of toxicity, or otherwise of deficiencies in the make-up of phloem-woody tissues are brought to light.
• Limb analysis: Next we carry out a determinant physiological analysis of the quality of the leaf structure and the richness of its photosynthesis.
• Leaf analysis: Mineral composition is a determinant stage in understanding the make-up of the leaf structure, photosynthesis potential, and chlorophyll performance. Supplementary analyses detect any parasites and fungal diseases.
• Berry analyses: These give us precise information on mineral components. As a supplement to limb analysis, they inform us as to the status of the fruit that differs from limb status at a time "T". They make it possible to anticipate anomalies in ripeness before they can be visibly detected.
