The work aims to describe the impact of scarification and sorting of pedunculate oak acorns and the time of sowing on the germination, growth traits (stem height, root collar diameter, total leaves area, number of leaves, dry mass), and the quality indices of seedlings grown in the Hiko container. The experiment was conducted on two dates: March 25 and April 21 in a container nursery in the Rudy Raciborskie...
The study aimed to determine the genetic variability in pitch pine (Pinus rigida Mill.) growing in the Niepołomice Forest (southern Poland). In the late nineteenth and early twentieth century, Adolf Cieślar of the Department of Forestry Research in Mariabrunn near Vienna, Austria established the experimental crops of pitch pine. During the study, 227 trees that grew in seven subunits were considered;...
In the study, the influence of soil compaction on the growth of silver fir seedlings (Abies alba Mill.) was evaluated; the soil compaction being measured using a cone penetrometer. The studies were conducted under a forest canopy, where the exploratory units with different soil compactions exerting a unit pressure of 50, 100, 150, 200, and 250 kPa, as well as the control units (without pressure),...
The paper presents the results of an analysis of the influence of soil bulk density in a forest nursery plot on the growth and quality parameters of Scots pine and European beech seedlings. Particular density variants were obtained using a tractor device exerting controlled pressure on the soil, while field examinations were performed on an area of ‘Kłaj’ forest nursery in Niepołomice Forest District...
Celem pracy było porównanie olejów lnianych (wysoko- i niskolinolenowego) oraz rzepakowego tłoczonych na zimno, które w ostatnich latach stały się popularne na polskich stołach. Badania obejmowały ocenę jakości chemicznej poprzez analizę liczby kwasowej, nadtlenkowej i liczby jodowej oraz określenie składu kwasów tłuszczowych. Wyniki wartości liczb określających jakość olejów były na różnym poziomie,...
