The studies evaluated the usefulness of concentrated beetroot juice, chokeberry and beetroot powder as potential tracers of spray deposits as well as their impact on the ability of conidia germination of Isaria fumosorosea and Lecanicillium lecanii. Aqueous solutions of beetroot and chokeberry products affected the physical properties of the spray liquid. The chokeberry juice concentrate at concentration...
Tasks imposed by contemporary agriculture on plant breeding are becoming increasingly complex. In order to meet these requirements breeders are applying various methods to expand genetic variability of stock materials for breeding work. Distant crossing is one of them. Wild subspecies are potential donors of such traits as resistance to diseases, adverse environmental factors or male sterility. Pollen...
Laboratory analyses were performed at the Department of Agronomy, the Poznań University of Life Sciences. Experiments were conducted on two strains of Trichoderma ssp. to investigate the aftereffect of sprinkling irrigation of blue lupin plants and seed soaking time (20, 40, 60 min). Results indicate a significant effect of Trichoderma ssp. strain and sprinkling irrigation on basic parameters of the...
Miscanthus sinensis (Andersson) is a perennial grass producing high amounts of biomass. I It can be used for energetic purposes through burning or biogas production. A main problem in this crop cultivation consists in vegetative, expensive method of propagation. First preliminary research on seed quality improvement is carried out in order to enable propagation on a large scale. The object of presented...
The study focused an assessing the influence of xenobiotics, such as NaCl and diesel oil on germination and early development of maize (Zea mays L.). Through the test the seed germination and growth inhibition of shoot and root of maize were evaluated. The experiments were carried out at different xenobiotics concentration and their mix. It was observed that the presence solely of compounds did not...
