Provenance selection and site conditions determine growth performance of pedunculate oak

Growth dynamics of crown shapes in stands of pedunculate oak and common hornbeam

Background and Purpose: Structure of crowns in forest stands is one of the main factors which determines growth and development of trees. Dynamic change occurs with the age of the stand due to silvicultural interventions or natural disturbances during which trees are removed from the stand. The aim of this article is to analyse the structure of the crown shape of pedunculate oak and common horn...

The role of myomorphous mammals as reservoirs of leptospira in the pedunculate oak forests of Croatia

In the year 2000, three hundred and eighty-one animals werw caught in 11 locations in the pedunculate oak forests extending across the wider region of the Sava River valley, an area known as an old natural focus of leptospires. Two hundred and twenty-seven animals were investigated for leptospiral carriership, 381 were tested for the existence of specific antibodies to leptospira. Through culti...

Influence of Torrefaction on Some Chemical and Energy Properties of Maritime Pine and Pedunculate Oak

This study investigated the influence of heat treatment on the chemical composition and energy properties of maritime pine (Pinus pinaster) and pedunculate oak (Quercus robur). Samples were treated in a new experimental device at 220, 250, or 280 °C for 1 or 5 hours. Chemical and energy analyses were performed using standard methods. Our results clearly demonstrated an increased degradation of ...

Hybridization and mating system in a mixed stand of sessile and pedunculate oak

Drought Effects on Physiology and Biochemistry of Pedunculate Oak and Hornbeam

Background and Purpose: Water stress is one of the major problems for urban trees. It affects a wide range of plant responses, from changes at the cellular level to the reduction in growth rates. Irrigation of trees in urban areas may provide numerous benefits important for increasing tree vitality to withstand other stresses that might occur. The aim of this study was to compare drought effect...
