Smoke-water and bulb growth

Hi

In the new "South African Journal of Botany" of March 2014, there are 
two articles related to smoke treatment.
The following links should go to the abstracts of the articles. 
Unfortunately I do not have access to the complete articles:

Smoke--water stimulates secondary metabolites during /in vitro/ seedling 
development in /Tulbaghia/ species
http://sciencedirect.com/science/article/…
and

Synthesis, X-ray structure determination and germination studies on some 
smoke-derived karrikins
http://sciencedirect.com/science/article/…

Enjoy
