Ilex paraguariensis and Ilex dumosa (Aquifoliaceae) germplasm evaluation

Ilex paraguariensis and I. dumosa are species with great economic relevance in Argentina. Both species share several features of their biology, though they differ in phytochemical composition and in their resistance to biotic and abiotic factors. The aim of the present work is to evaluate the struct...
