摘要

水是灭火最常用的物质。发泡剂是提高灭火效率最常用的添加剂之一。本文研究了发泡剂对针叶树种子萌发的影响。采用不同浓度的发泡剂Moussol-APS F-15和Sthamex F-15发泡溶液进行试验。对挪威云杉(Picea abies)和苏格兰松(Pinus sylvestris)种子的萌发进行了观察。每7 d记录种子发芽率。结果以图表的形式进行了评价。当发泡溶液浓度在0.1 ~ 0.25 vol%范围内时，其对两种针叶树种子萌发的影响从可忽略到略为正。随后，负面影响显著增加，当浓度超过1vol % - 1.5 vol%时，样品的萌发达到零值。Sthamex F-15发泡剂对苏格兰松种子萌发的影响不显著，而Moussol-APS F-15发泡剂对挪威云杉种子萌发的影响较小。根据获得的结果，可以建议尽量减少发泡剂的用量，最终使用对植物发芽负面影响较小的物质来扑灭野火，以便尽快恢复受灾地区。关键词:发泡剂;发芽;野火

The influence of synthetic foaming agents on seed germination of coniferous species

Water is the most frequently used substance for extinguishing of wildfires. Ones of the most commonly used additives enhancing the extinguishing efficiency are foaming agents. This article deals with the influence of foaming agents on germination of coniferous species. Foaming agents Moussol-APS F-15 and Sthamex F-15, foaming solutions of various concentrations were used for the tests. Germination of seeds of Norway spruce (Picea abies) and Scots pine (Pinus sylvestris) was observed. The percentage of germinating seeds was recorded every 7 days. The results were evaluated in the form of graphs. When the concentration levels of foaming solutions ranged from 0.1 vol% to 0.25 vol%, their influence on germination of both coniferous species seeds varied from negligible to slightly positive. Subsequently, the negative effect increased considerably and with concentrations exceeding 1 vol% - 1.5 vol% the germination of samples reached zero values. While foaming solutions of Sthamex F-15 showed less significant influence on germination of the Scots pine seeds, seeds of the Norway spruce were less influenced by foaming agent Moussol-APS F-15. Based on obtained results it is possible to recommend minimisation of foaming agents amounts, eventually application of substances with less negative effect on plants germination for extinguishing of wildland fires, in order to gain restoration of affected area as fast as possible. Key words: foaming agent, germination, wildfire (wildland fire), foaming solution

期刊介绍： The journal welcomes the original articles as well as short reports, review papers on forestry and forest science throughout the Baltic Sea region and elsewhere in the area of boreal and temperate forests. The Baltic Sea region is rather unique through its intrinsic environment and distinguished geographical and social conditions. A temperate climate, transitional and continental, has influenced formation of the mixed coniferous and deciduous stands of high productivity and biological diversity. The forest science has been affected by the ideas from both the East and West. In 1995, Forest Research Institutes and Universities from Estonia, Latvia and Lithuania joined their efforts to publish BALTIC FORESTRY.
