The purpose of the studies was to observe the dynamics of number of Metopolophium dirhodum (Walk.) on rugosa rose, multiflowered rose, park rose cv. ‘Grandhotel’ and different varieties of border roses. Observations were conducted in four different sites in the green area of Lublin in the years 2001–2003. M. dirhodum was observed on all the analyzed roses. Annually this aphid colonized only the shrubs...
Effect of auxins: (NAA, IAA), cytokinin BAP and culture conditions (light, darkness) on callus induction in cotyledons of tomato cultivar ‘Maskotka’ and the wild form of Lycopersicon peruvianum was investigated. Callus was obtained in all experimental combinations, except of the culture with L. peruvianum on the medium with 1.0 mg⋅dm⁻³ of IAA. Callus weight, colour and structure depended on the tomato...
The aim of the experiment was to assess the effect of applied fertilizers: Hydrocote + Kristalon, Osmocote + Peters and Polyon + Hortimix on the length of the production period and the quality of two heterosis cultivars of Cyclamen persicum from Halios group during two years of the study late date cultivation. The experiment was conducted in the following cycles: 04.08.2003–12.01.2004 and 29.07.2004–30...
The object of the studies were soybean plants grown of the seeds dressed with Polyversum, Biochikol 020 PC and Biosept 33 SL. At anthesis those plants were sprayed with the same biopreparations. The experiment considered a combination with the chemical preparation Zaprawa Oxafun T for seed dressing, and Bravo Plus SC for spraying plants at anthesis. It can be stated on the basis of the obtained results...
Vegetation studies were conducted from 2002 to 2004, in two leading farms, located near Poznan where have obtained optimum anthurium (Anthurium cultorum Birdsey) yielding. Plants were grown in expanded clay with the application of fertigation with a standard nutrient solution (in mg·dm⁻³): N-NH₄<14.0, N-NO₃ 105.0, P 31.0, K 176.0, Ca 60.0, Mg 24.0, S-SO₄ 48.0, Fe 0.840, Mn 0.160, Zn 0.200, B 0...
On the basis of the experimental data of COBORU the time and spatial distribution of the dates of sowing, harvesting and of the cucumber (conserve varieties) growth stages in western Poland was characterized. The length of the conserve cucumber growth periods varied more in the years 1965–2004, and it was on average seven times as large as the length of agrotechnical and phenological periods and the...
The purpose of the studies was to determine the effect of such preparations as Biochikol 020 PC, Polyversum and Biosept 33 SL on the formation of microorganisms communities in the rhizosphere soil of soybean. Results of the studies pointed to a positive effect of biopreparations on the increase number of cfu total bacteria, Bacillus spp. and Pseudomonas spp. After the application of biopreparations...
