&-lt;i&-gt;Potenciál využití brassinosteroidů v lesním semenářství, školkařství a při zakládání lesa&-lt;/i&-gt; / @Potential of brassinosteroids for forest seed and nursery management and for forest regeneration@

Bach, Petr January 2015 (has links)
Brassinosteroids (BRs) are a class of polyhydroxysteroids that have been recognized as a sixth class of plant hormones. In specific conditions BRs can positively influence the plant growth and development. The first isolated brassinosteroid was natural Brassinolide from rapeseed (Brassica napus L.). Recently BRs are extracted primarily synthetically; they are effective even in very low concentrations. Several studies of different plant species show positive influence of BRs on growth, flowering, germination and resistance to stress factors. Existing scientific studies that deal with BRs impact on plants were predominantly applied on agricultural crops. Until presence, the similar research in forest seed treatment and forest nursery was almost missing. In the Czech Republic the Department of Silviculture of the Faculty of Forestry and Wood Sciences of the Czech University of Life Sciences Prague newly started to deal with the use of BRs in forestry. The aim of this master thesis is to elaborate literature review on BRs and to summarize existing research of their impact on plants. Second part of the thesis solves influence of BRs on Scots pine (Pinus silvestris) seeds germination. Tests are performed in normal and in stress conditions. Results of the practical part show that BRs affect positively seed germination in normal conditions; seeds treated with BRs show higher germination rate than control seeds. Positive impact was not registered when the seeds were exposed to stress factor -- heat. Any research paper showing significant positive influence on forest seedlings in Central European conditions was not published yet.
