英文摘要	Direct seeding is one of the most feasible techniques in practical, logistical, and economic terms for large-scale restoration of arid lands. However, several factors are still under study to enhance the outcomes of this restoration alternative, with species selection being a pivotal component. To evaluate differences in the performance of species in direct seeding, we selected five shrubs from the arid region known as Monte Desert in Argentina: Atriplex lampa, Hyalis argentea, Larrea divaricata, Neltuma flexuosa var. depressa, and Parkinsonia praecox. Direct seeding was carried out in furrows (4.0 m long, 0.5 m wide, and 0.4 m deep) with seeds previously treated to dormancy alleviation and with a density of 250 seeds/m2. We evaluated results in 12 furrows, where topsoil and hydrogel were deposited. The biological variables considered were seedling emergence, seedlings establishment regarding sowed seeds, and seedling success (survival in relation to emerged seedlings) after almost 3 years. The species with the highest emergence and establishment rates was A. lampa (50.16 and 23.75%, respectively). L. divaricata showed the lowest values for these variables (2.17 and 0.83%, respectively). On the other hand, the survival of N. flexuosa seedlings was >2x that of L. divaricata (65.02 vs. 30.36%). We discuss the notable differences in species performance and the possible role of furrows in the results.
