An essay proves that vegetation could recover in the ski resort of Sierra Nevada
Date:12/12/2008

th processes". The main problem of bushes is that, in the short term, "they do not manage to regulate themselves to recover their biodiversity naturally".

Seeds growing in the laboratory

The study has been carried out from three different samples of several soils of the ski resort. The goal is to test if these species seeds are able to grow in different experimental conditions. Soils have not been contingent; they were selected according to the orientation, the slope, the height and the location of the runs in the resort, among other aspects.

Treatments with different vegetable growth regulators (auxins, gibberellins, cytokinins and ethylene) were applied to the seeds "to improve germinative and growth percentages in laboratory and make easier the later transfer and application of the results to the ski resort", the researcher says.

Seeds germinated and grew successfully in the laboratory. According to Serrano, the effectiveness of the regulators has been tested in aspects such as the formation of the radical system, stem elongation, cotyledon expansion (simple leaves which feed the plant) or leaves appearance.

Once the treatments are applied to the field, they are expected to "favour the recovery of the vegetable cover in a space of time considerably lower to that needed without any intervention", the experts say.
