Effect of Polymers on Scots Pine ( Pinus Silvestris L.) And Austrian Pine ( Pinus Nigra Arn.) Seedling Development In Afforestation

摘要

The increase in forest cover percentage is one of the strategic goals in many countries. The realisation ofsuch an ambitious plan is all the more difficult under the climate changes which appreciably reduce theplanting season and negative impact on plant survival and development, due to long, hot and dry summers.Also, the uncovered areas intended for re/afforestation are mainly difficult terrains, damaged by wildfires, ordegraded in other ways. Such soils, without the humus horizon, most often of south and southeast aspect,ecologically unfavourable because of strong insolation and the lack of moisture, without forest cover and withforest mycoflora completely missing, require the application of modern re/afforestation technologies combinedwith the latest scientific knowledge.
