Genetic Variability and Structure of The Wild Service Tree (Sorbus torminalis (L.) Crantz) in Poland

Pollen flow in the wildservice tree, Sorbus torminalis (L.) Crantz. I. Evaluating the paternity analysis procedure in continuous populations.

The joint development of polymorphic molecular markers and paternity analysis methods provides new approaches to investigate ongoing patterns of pollen flow in natural plant populations. However, paternity studies are hindered by false paternity assignment and the nondetection of true fathers. To gauge the risk of these two types of errors, we performed a simulation study to investigate the imp...

Impacts of gene flow and logging history on the local genetic structure of a scattered tree species, Sorbus torminalis L. Crantz.

Sorbus torminalis L. Crantz is a colonizing tree species usually found at low density in managed European forests. Using six microsatellite markers, we investigated spatial and temporal patterns of genetic structure within a 472-ha population of 185 individuals to infer processes shaping the distribution of genetic diversity. Only eight young stems were found to be the result of vegetative repr...

Diversity of arbuscular mycorrhizal fungal spores associated with Sorbus torminalis (L.) Crantz

This study aimed to investigate the diversity and types of arbuscular mycorrhizal fungi (AMF) associated with the wild service tree, Sorbus torminalis (L.) Crantz in spring and autumn followed by identifying similarities among the different study sites. Three different sites were selected including Kheiroud, Lalis, and Tarkin, in the Hyrcanian forests, north of Iran. Five rhizosphere soil sampl...

ریز ازدیادی بارانک (Sorbus torminalis (L.) Crantz) یک: مرحله استقرار و شاخه زایی

Regional population dynamics define the local genetic structure in Sorbus torminalis.

Recent changes in sylvicultural practices in Central Europe have created forests with closed canopies, and tree species preferring open and sunny forests have declined in area and abundance. This led to increased isolation of populations of many rare insect-pollinated, fleshy-fruited species with a naturally scattered distribution. To gain insight into the regional population dynamics of such s...
