Five stocklots with a contrasting seedling quality were planted on six different sites showing different ecologic conditions in a same regional context. This reciprocal study indicated that site factors climate meteorology and soil explained most of the variability found over stock quality factors material and performance attributes in the overall performance results F values for final survival were and for site and stocklot respectively . There were significant interactions between both factors in survival F for final survival and first growth indicating that the seedling quality attributes associated with a better performance depended on site conditions with physiological attributes being more dependent on the site than morphological attributes. The lower the site quality poor performance the higher the importance of stock quality especially that related with seedling size and macronutrient content which showed positive correlations p with survival yielding differences of over 30 between stocklots. In general a milder climate and a shallow site meant a higher mortality. The .
