| Sumario: | A large area of the province of Mendoza has suffered negative impacts due to unsustainable
exploitation and the consequent destruction of the forest mass resulting from natural or
caused fires. For that reason, to remedy it a reforestation is proposed, so the behavior of
Prosopis flexuosa in nursery was evaluated based on different substrates and seed origins.
Four types of substrate were tested according to their (vermicompost content:sandy loam)
proportion, among them we have: type B (1: 5), type C (1: 3); type A (5: 7) and type C (only
sandy loam). Two seed origins were used: Bolsón de Fiambalá (Catamarca) and General
Alvear (Mendoza). Once the minimum number of seedlings per repetition that was
considered adequate was achieved, in this case fifteen, data collection began. The
measurements were made with a difference of 69 days between the first and the last day.
With it, the variables delta diameter at the root neck and delta height were constructed. In
the trial, significant differences were found for these variables according to the substrate and
the seed origin. The best combination is given by the seeds from the Bag of Fiambalá with a
substrate containing at least 1 part of humus per 3 of sandy loam |
