The effects of soil conditioners Frisol, TerraCottem, Bi-algeen, and fertilisers Silvamix Forte and Cererit on the welfare of Austrian pine were observed in a seven-year experiment on Loket spoil ba...
In this article the stem shape is compared in three coniferous tree species: Norway spruce, Scots pine and European larch. Stem is investigated by means of geometrical methods. Simplified Bookstein ...
We studied effects of repeated applications of nitrogen on stem growth of mature Scots pine at four sites with yield potential around 3 - 4.5 m3 ha‑1 yr‑1. Treatments included control (0) ...
The paper evaluates the growth, structure, production, quality, leaf area index and dendrochronology of 100 years old Austrian pine (Pinus nigra ARNOLD) monoculture situated in the forest type group F...
This is a study on the evaluation of stem shape in Scots pine. The experiments were carried out on 430 stems without bark, taken from 30 fully analysed sample trees that grew in 5 different locations ...
Needle retention (number of needle sets) and needle density (number of needle pairs per centimeter of shoot) were surveyed on Scots pines in five forest regions of Slovakia. The Needle Trace Method (N...
We examined the impacts of variation in overstory structure and burning regime on understory vegetation in the longleaf pine (Pinus palustris Mill.) forest of the Okefenokee National Wildlife Refuge i...
The aim of this study was to determine some of the anatomical, physical, and mechanical properties of 35-year-old Pinus eldarica Medw. wood. For this purpose, 3 normal pine trees were randomly cut dow...
In this study, the influence of infestation by mistletoe (Viscum album L. subsp. austriacum (Wiesb.) on the annual diameter increment of Anatolian black pine (Pinus nigra Arn. subsp. pallasiana (Lamb....
We inoculated the pine wood nematode, Bursaphelenchus xylophilus, into Pinus thunbergii seedlings, and investigated the progress of symptoms of pine wilt disease and dynamics of B. xylophilus in the s...
The migration of pinewood nematode, Bursaphelenchus xylophilus, inoculated on the top of 10-cm-long stem cuttings obtained from the current shoots of two types of Pinus thunbergii seedlings—a resistan...
The relationships between characteristics of band and luminance and classification of the tree vigor of aged, large-diameter Japanese Red Pine was performed using high-resolution IKONOS satellite data...
To obtain the pine trees with high resistance to the pine wilt from susceptible species, the criteria for selective breeding should be made based on the inhibition factors of symptom development. Migr...
Inoculation of an avirulent isolates of the pinewood nematode, Bursaphelenchus xylophilus, is known to induce resistance in Japanese red pine (Pinus densiflora) trees to pine wilt disease caused by vi...
We investigated the relationship between degeneration of tissues and death of potted 3-year-old seedlings of Japanese black pine, Pinus thunbergii, from 6 families with different resistance, inoculate...
