Damp water stream impact for the germination of Norway Spruce (Picea Abies (L.) H. Karst.) seeds

Abstract

Growing of economics and new technologies caused the environment pollution and more intensive using of natural resources. The principles of stable and balanced forestry became more and more important. Ecologization forests economy directly and indirectly impact environment, water, air, landscape. One of the most widely applied measures to protect seeds from the damage caused by fungi is spreading diseases are treaters. It is not allowed to use chemicals in ecological farms. In Lithuania the number of ecological farms is growing that is why the new effective ecological methods are needed to protect seeds from diseases. Alternative is to use high temperature. All live organisms are destroyed in a high temperature environment. It is very important to find optimal treatment time of high temperature so that pathogenic organisms would be destroyed but germination characteristics of the seeds would remain unaffected. Investigation performed made on 2009-2010 in Forest's Seeds and Plantings Quality Department laboratory and Siauliai Forest Enterprise nursery. It was investigated how a damp water steam effects germination of Norway Spruce (Picea abies (L.) H. Karst.) seeds. Control sample was not affected by damp water steam and it's germination was 95.8%. Thermally treated seeds germination varied between 95.9% and 82.4% depending on treatment time in high temperature environment. Here wise the research of fungicide MaximStar 025 FS (2 g/kg) was used for the seeds chemical treatment. Germination of these seeds was about 44.86 %. Whereas germination of seeds treated by damp water steam varied between 61.1% and 78.6%.
