Resumen

SEPULVEDA, Bernardo; SANTANA, Ricardo  y  SOTO V, Juan. Mass forced production of wild trees from the Atacama desert, Copiapó (Chile). Idesia [online]. 2016, vol.34, n.3, pp.7-16. ISSN 0718-3429.  http://dx.doi.org/10.4067/S0718-34292016000300002.

In arid zones the loss ofbiodiversity, plant cover and biomass are permanent environmental problems. Under arid natural conditions, seeds of wild species usually germinate in irregular periods and in long time, making it difficult to use these species in productive processes. Suitable conditions for optimizing and producing massively wild trees from seeds of species from the Copiapó Valley were evaluated, using treatments of reaming and hormonal induction ofgermination with GA3. The induction conditions for each tree species and the effective plant production capacity was determined. Plant production increased 83.8% on the production of plants in nurseries before the project, by increasing of the germination. Using the production protocol, 25,000 plants from different species by week were produced, with a annual projection which would be possible to control the artificial production of wild plant species. The massive propagation ofplants could be a tool to conservation of natural populations of wild species and give potential to use it in production process.

Palabras clave : trees from arid zones; pregerminative treatment; massive plant production.
