%X a "vara de perlilla" (symphoricarpos microphyllus h.b.k.) plantation was established in the forest nursery of the divisi¨®n de ciencias forestales, universidad aut¨®noma chapingo. the objective was to study survival and growth under different solar radiation condi-tions. the shrubs were planted under a pine forest plantation in different light conditions. with a digital camera with hemispheric lens and the hemiview program£¿, were measured direct and diffuse solar radiation, and visible sky. from the shrubs was recorded survival, number and length of branches, shoot and root biomass and total biomass. the probability of mortality was obtained with a logistic model, using as explanatory variable direct solar radiation. also was employed linear regression. the logistic model was significant (p= 0.0970), with higher mortality at higher light levels. the lineal regressions were not significant or had a verly low r2.
