DOLL, Ursula; FREDES V, Michelle  y  SOTO V, Cecilia. Effect of different pre-germination treatments on germination of six native species from the mediterranean area of Chile. Idesia [online]. 2013, vol.31, n.3, pp.71-76. ISSN 0718-3429.  http://dx.doi.org/10.4067/S0718-34292013000300010.

Many species of the native flora from north and central Chile stands out in their capacity to withstand extreme edaphic conditions and also presents strategies to survive under water deficit conditions. These characteristics make them especially amenable to be used in vegetable covers to stabilize slopes. In this context, 6 native species which usually grow on old road slopes in the mediterranean area of Chile were chosen to be used to revegetate slopes using the hydroseeding technique. 2 trials were carried out in a germination chamber with the aim to determinate the seeds' germination requirements. The germination capacity was tested under pre-germination treatments as soaking in either cold or hot water, and cold stratification. Stratified seeds of Melica violacea germinated after 5 days, and seeds of Baccharis linearis soaked in hot water showed their maximum germination energy on day 7, reaching a germination capacity of 99% and 91% respectively. Both species seems to be promising for revegetating slopes with the hydroseeding technique.
