Wc have sludied severa l paramelers in Triticum durum Desf., cultivated organically in the same period in two localities with different microclimatic conditions. We particularly investigated phenological parameters such as growth, plant development and net photosynthesis. The aim was to see if there existed any difference due not only to factors commonly involved in biodiversity, bui also to factors such as productivity (Waide & al. 1999) and peculiarities of the functional group (Cody 1975; Leonardi 1998). The observations and measurerncnts carried out on Triticum durum Desf. show quite different growth patterns and potential productivity.
