ECOPHYS is a complex computer model that simulates the growth of hybrid poplar and aspen trees. Its primary purposes are to identify major physiologically-based factors that influence tree growth and to predict how interactions among them and with the external environment will affect growth (Isebrands et al., 2000). ECOPHYS' capabilities and submodels of various tree ecosystem processes continu...

A method was developed for scaling-up the AFRCWHEAT2 model of phenological development from the site to the continental scale. Four issues were addressed in this methodology: (i) the estimation of daily climatic data from monthly values, (ii) the estimation of spatially variable sowing dates, (iii) the simulation of multiple cultivars, and (iv) the validation of broad-scale models. Three method...

Knowing the current phenological state of an agricultural crop is a powerful tool for precision farming applications. In the past, it has been estimated with remote sensing data by exploiting time series of Normalised Difference Vegetation Index (NDVI), but always at the end of the campaign and only providing results for some key states. In this work, a new dynamical framework is proposed to pr...

The aim of the study was (1) to compare antimicrobial activity essential oils (EOs) obtained from leaves and inflorescences Monarda media, didyma citriodora found in different phenological stages development, (2) examine inhibition microbial growth by EOs O/W emulsions. Thymol, p-cymene carvacrol were main constituents EOs. strongest flowering phase development. M. media EO fulfilled criterion ...
