FONTANA, ANA, M. L; PEREZ, V. R  and  LUNA, C. V. Pruebas de envejecimiento acelerado para determinar vigor de semillas de Prosopis  alba de tres procedencias geográficas. FAVE. Secc. Cienc. agrar. [online]. 2016, vol.15, n.1. ISSN 1666-7719.

In order to create conceptual basis for determining the quality of Prosopis alba´s seeds through accelerated ageing tests, vigor was determinated conducting trials with moist heat (MHAA), dry heat (DHAA) and saline solution (AASS) on seeds from three geographical origins: Santiago del Estero, Formosa and north of Salta province. Significance was determined for Provenance*Treatment interaction and was determined that the MHAA is the only procedure applicable to all provenances because significantly affect the aging index (AI). According to IE measured after MHAA test, Chaco provenance showed the best performance followed by Santiago del Estero and Salta Norte stands, which are equal to each other. Vigor evaluation allowed the provenances to be distinguished through qualities not detected in normal germination test under standard conditions
