La coltivazione di alcune piante ornamentali esotiche: il caso della Thevetia peruviana, della Dodonaea viscosa, della Polygala myrtifolia e dell’Hebe salicifolia.

The paper reports the preliminary results of a research carried out within the project "New agronomic techniques and innovative cultural systems based on biodegradable and/or compostable pots" (SCIMAB), financed by the Italian National Operative Program (PON). Trials have been conducted in an unheated greenhouse located in Monopoli (BA), evaluating the morphological and physiological behavior, from the seeding or transplant to the marketing phase, of the studied plants placed in different pots. Results have shown that the cultural cycles length depend on the species, because of the propagation and of the adopted cultural techniques.
