    Opis:
    The objective of this study was to characterise the quality of giant pumpkin dried in different conditions as well as to determine the best combination(s) of drying conditions, based on colour and chemical composition of dried material. Samples of three pumpkin cultivars (Amazonka, Justynka- 957 and Ambar) were dried at five different temperatures (40°C, 50°C, 60°C, 70°C, 80°C) using three different drying methods (forced convection in tunnel dryer, natural convection in chamber dryer and hybrid drying which combined a tunnel drying and fluidized-bed drying). It has been shown that variability of samples resulted primarily from the redness, yellowness, lutein and β-carotene. Samples were scored based on the range of responses identified by factor analysis in order to find an optimal combination of cultivar, temperature and drying method. The three subsequent highest scores were obtained for samples of Ambar cultivar, dried using hybrid drying at 40, 60 and 80°C respectively.

    Opis:
    The aim of this study was to evaluate the yield variability of spring barley families grown at the Nagradowice Plant Breeding Station of Poznan Plant Breeding against other families studied in years 2017‒2018 in Team Breeding Experiments. Research material included 250 spring barley families cultivated in 2017 and 2018 in 6 locations. Selection of spring barley families for preliminary experiments was based on synthesis of results obtained in inter-plant experiments established in 2016 and 2017 in 5 locations. Combined (due to location) analysis of variance for experimental data was performed for each year and each series of experiments separately. Best Weighted Linear Unbiased Estimators (BWLUE) for the effects of individual sources of variation were included in ANOVA model. Significant effect of location on mean yield was observed in each research year and each series of experiments. Crucial differences were also observed between tested varieties and breeding lines. Moreover, significant interaction between locations and varieties or breeding families was also observed. Self-organising map (SOM) was applied to develop multivariable characteristic of tested families and cultivars of spring barley. Analyses results, i.e. ranking of BWLUE effects as well as SOM segmentation revealed seven breading lines from Breeding Station Nagradowice, which may be considered for further breeding process.

    Opis:
    Abiotic stressors contribute to growth restriction and developmental disorders in plants. Early detection of the first signs of changes in plant functioning is very important. The objective of this study was to identify chlorophyll fluorescence parameters that change under phosphorus deficiency stress in cucumber. In this work, a trail to study the early changes caused by phosphorus deficiency in cucumber plants by analysing their photosynthetic performance is presented. Chlorophyll-a fluorescence (ChF) parameters were measured every 7 days for a period of 28 days. Measurements were made separately on young and old leaves and on cucumber fruit. Parameters that decreased during the stress were: p2G, PI abs, PI total, REo/CSo, and TRo/CSo. P deficiency decreased total electron carriers per RC (ECo/RC), yields (TRo/ABS (Fv/Fm), ETo/TRo, REo/ETo, ETo/ABS and REo/ABS), fluxes (REo/RC and REo/CSo) and fractional reduction of PSI end electron acceptors, and damaged all photochemical and non-photochemical redox reactions. Principal component analysis revealed a group of ChF parameters that may indicate early phosphorus deficiency in cucumber plants. Our results are used in the discovery of sensitive bioindicators of phosphorus deficiency in cucumber plants. Most JIP test parameters are linked to mathematical equations, so we recommend using of advanced statistical tools, such as principal component analysis, which should be considered very useful for stress identification. It has also been shown to be more effective in multivariate methods compared to univariate statistical methods was demonstrated.
