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...
Black alder, a major forest tree species in Europe, thrives in moist soils. During the seeds extraction (nutlets) from the cones, the heaviest seeds were observed to fall out first. Seed weight was not correlated to the ability of germination; no significant differences were observed between the heaviest and the lightest seeds. Seeds with a fresh mass moisture content of 8−9% after storage in –3°C...
W latach 2008–2010 przeprowadzono doświadczenia na stanowisku z piaskiem gliniastym lekkim. Badania miały na celu porównanie dynamiki wzrostu roślin i udziału roślin kwitnących w trzech terminach oraz plonu nasion i masy 1000 nasion dziesięciu odmian gorczycy białej uprawianych w plonie głównym. Odmiany gorczycy białej różniły się istotnie wysokością roślin, kwitnieniem, plonem nasion i masą 1000...
