ABSTRACT = {In arid and semi-arid ecosystems, increasing and irreversible
degradation in areas of high conservation value has prompted
the search for various solutions, such as rehabilitation and ecological
restoration. To implement these strategies, it is essential to solve
critical issues affecting the establishment of plants in the field and
the production of seedlings in nursery gardens. In the present work,
the following pre-germination treatments were evaluated for the
species <i>Senna arnottiana</i> and <i>S. kurtzii</i>, endemic to the Patagonian
steppe (Payunia): (1) Immersion in water at 80 °C for 5 minutes; (2)
Immersion in water at 80 °C for 10 minutes; (3) Immersion in water
at 100 °C for 5 minutes; (4) Immersion in water at 100 °C for 10
minutes; (5) Acid scarification with sulfuric acid for 30 minutes; (6)
Acid scarification with sulfuric acid for 60 minutes; (7) Soaking in
water at 80 °C until cooled for 24 hours, and (8) Control (no treatment).
For both species, the highest, fastest, and most homogeneous
germination was obtained with acid scarification, i.e., 70% germination
for <i>S. arnottiana</i> and 95% germination for <i>S. kurtzii</i>. Although
this method requires the use of a laboratory and has a high economic
cost for local residents, the high germination percentages obtained
make it highly recommended for the production of large quantities
of seedlings.},
