Scots pine seed dynamics on a waterlogged site

Abstract

Scots pine (Pinus sylvestris) grows some 400 km south of its current native limit at Wybunbury Moss, Cheshire, UK, on a peatland around a small floating bog (Schwingmoor). Cone and seed production of trees, which have been growing on the site for just over 100 years, were investigated over 3 years. Cones matured between September and March and seed shedding began in early April. The number of cones produced per reproductive tree ranged between 31 and 2,418, with a total average of 685 cones tree -1 y -1 . A strong relationship was found between tree diameter and seed production which allowed the prediction of annual seed production. Scots pine on this peatland produced between 766,874 and 950,000 seeds ha -1 annually with a germination percentage of 64%. The predicted number of seeds reaching the central bog (maximum of 120 m from the trees) every year was c. 16,000.

Attributes of Naturally Fallen (Rained) <i>Melaleuca quinquenervia</i> Seeds in Two Habitat Types of South Florida Wetlands

“…These larger trees are expected to generate higher quantities of monthly seed fall in the forest stands. This assumption is corroborated by the results of a study on scots pine (Pinus sylvestris L.) that showed an increase in the number of seeds fallen with an increase in tree sizes [26].…”

Colonization in Mediterranean old‐fields: the role of dispersal and plant–plant interactions

“…; Mukassabi et al. ). Juniperus sabina favoured survival of juveniles of J. communis and P. sylvestris in one plot but interfered with them in another, highlighting the importance of context on the outcome of biotic interactions (Bertness & Callaway ).…”

“…Additionally, we assumed that the contribution to recruitment of older pines was higher than that of younger ones (Mukassabi et al. ). We systematically varied the unknown parameters σ s and σ l of the normal distributions and selected those with the best fit (Rodríguez‐Pérez et al.…”

Effect of age of plantation on seed characters and growth performance of Tokopatta (Livistona jinkensiana Griff.) seedling

“…Mother tree age is known to have significant effect on seed quality and quantity. The seed production of Pinus sylvestris (Mukassabi et al 2012) and Picea mariana (Viglas et al 2013) increased steadily with mother tree age. In terms of quality, some tree species exhibited the highest seed germination rate in the middle age, such as Pinus echinata (Grayson et al 2002) and Sorbus torminalis (Espahbodi et al 2007) In general, it is recommended to collect seeds during the mid-age period of the individual.…”
