Biochemical and structural characteristics of Scots pine (Pinus sylvestris L.) in an alkaline environment
Investigations in a 7585-year-old Scots pine stand were performed on a territory influenced over 40 years by alkaline dust pollution (pH 12.312.7) emitted from a cement plant. Sample plots were located at distances of 2, 3, and 5 km E of the emission source and a control sample plot was selected on an unpolluted territory 38 km W of it. We studied soil properties and the anatomical structure,...
متن کاملBiochemical Plant Responses to Ozone : II. Induction of Stilbene Biosynthesis in Scots Pine (Pinus sylvestris L.) Seedlings.
Formation of the stilbenes pinosylvin and pinosylvin 3-methyl ether, as well as the activity of the biosynthetic enzyme stilbene synthase (pinosylvin-forming), were induced several hundred- to thousandfold in primary needles of 6-week-old pine (Pinus sylvestris L.) seedlings upon exposure to a single pulse of ozone of at least 0.15 microliters per liter. The seedlings required 4 hours of exposu...
متن کاملEstimating sapling vitality for Scots pine (Pinus sylvestris L.) in Russian Karelia
A new method is proposed for estimating vitality or growth potential for saplings of Scots pine (Pinus sylvestris L.), based on height, diameter and height increment. A two-stage process was used to establish the vitality index. The logarithms of height, diameter and height increment were regressed against age, to adjust for the wide range of ages present in our data (c. 10,000 saplings with ag...
متن کاملAging in Pinus sylvestris L. seeds: changes in viability and lipids.
Aging of Scots pine seeds (Pinus sylvestris L.) leads to changes in seed quality, such as loss of germinability, delayed growth and abnormality in developing seedlings. The knowledge of biochemical changes responsible for these aging processes is plentiful in some seeds, which are of world-wide interest, but for pine seeds these studies are rare. The aim of the present study, was to analyse pin...
متن کاملFungal Infection Increases the Rate of Somatic Mutation in Scots Pine (Pinus sylvestris L.).
Somatic mutations are transmitted during mitosis in developing somatic tissue. Somatic cells bearing the mutations can develop into reproductive (germ) cells and the somatic mutations are then passed on to the next generation of plants. Somatic mutations are a source of variation essential to evolve new defense strategies and adapt to the environment. Stem rust disease in Scots pine has a negat...
