EVALUATION OF SELECTED POPPY (Papaver somniferum L.) CULTIVARS: INDUSTRIAL ASPECT

Milan SKALICKY, Vaclav HEJNAK, Jan NOVAK, Alena HEJTMANKOVA, Irena STRANSKA

Abstract

Fifty-six genotypes (usually cultivars) of various origins, from twelve countries, were analysed for morphine production and significant characteristics of the capsule. The Saaty’s method was used to analyse the aspect of morphine production and significant characteristics of the capsule, comparing those values representing significant indicators for that production and the content of morphine in poppy straw. This covered the relation to ideotype (‘ideotype cultivar’) of poppy, with 100% values in the monitored indicators. In the case of white-seed poppies, generally with a lower content of morphine, in three cultivars (´Pulawski bialy´, ´Bělosemenný´, ´Bulharský slepák bílý´) the value of the industrial indicator was determine over 50% and the content of morphine over 0.50% in the poppy straw. In the set of blue-seed cultivars with three production levels, four cultivars were found with values exceeding 80% of the industrial indicator and morphine in poppy straw over 0.90%. In the set of grey-seed cultivars, four production levels were identified based on the values of morphine and the industrial indicator, while the first two showed good values for production - at least 0.52% of morphine in poppy straw and 50% of the industrial indicator (for example ´Soproni tef´, ´Šarišský´).

Effects of Different Water Stress Levels on Biomass Yield and Agronomic Traits of Switchgrass (Panicum virgatum L.) Varieties under Semi-Arid Conditio

Erdal GONULAL, Suleyman SOYLU, Mehmet SAHIN

Abstract

A field experiment was conducted in the Wielkopolska region at the Gorzyń Research Station, Poland (52.34°N, 15.54°E) in Central Europe. The study was conducted over a 3-year period (2017, 2018, 2019) as a two-factorial design with four replications in the RCBD. The aim of the research was to determine the effect of the cultivar (‘Bolero’, ‘Tytan’) and the inoculation (Nitragina–seeds inoculation, Nitroflora I–seeds inoculation, Nitroflora II–soil inoculation, HiStick® Lupin–seeds inoculation) on plant development, seeds chemical composition and yielding of narrow-leaved lupin. The weather conditions and experimental factors significantly influenced on productivity of narrow-leaved lupin ‘Tytan’. Drought during the growing season reduced seeds and protein yields. After inoculation of HiStck the seeds yield was significantly greater by 12.4% (p < 0.01) and the protein yield after application of Nitroflora I or HiStick by 13.9% (p < 0.01) and 19.2% (p < 0.01), respectively. Correlation coefficients showed strong relations between number of pods and seeds per plant in both cultivars regardless of the inoculation variant, however the strongest relations in both cultivar were proved on HiStick treatment.
