Introduction
 Poplars and aspens (Populus sp.) are common in forest stands, shelterbelts, rural landscaping, special plantations as short-rotation woody crops; they promising tree species for biofuel bioenergy production. Wood-boring insects browse galleries a stem or branches that interrupt sap circulation promote infestation by plant pathogens. Some of these can additionally weaken trees...

Leaf water content (LWC) is a crucial physiological parameter that plays limiting role in the efficiency of photosynthesis and biomass production many plants. This study investigated use diffuse reflectance near-infrared spectroscopy (NIRS) for rapid prediction gravimetric LWC eucalypt leaves from Eucalyptus Corymbia genera. The best-performing model gave R2pred 0.85 RMSEP 2.32% an independent ...
