Yew is a coniferous, evergreen, dioecious species. The objective of the study was to present a comprehensive characteristic of changes occurring throughout the year in terms of the content of photosynthetic pigments and related compounds in the needles of yew, depending on the sex of individuals and age of needles. Eight compounds, particularly chlorophyll a (Chl a), chlorophyll b (Chl b), carotenoids (Car), protoporphyrin IX (PPIX), magnesium protoporphyrin IX (MgPPIX), protochlorophyllide (Pchlide), chlorophyllide a (Chlide a), and chlorophyllide b (Chlide b), were subjected to quantitative analysis. Based on the several parameters under study, significant differences between male and female individuals were observed, while most commonly, the largest differences were reported in the autumn and winter period. They were related to the content of Chl a, Chl b and Chl/Car ratio. The remaining compounds showed no significant differences according to the sex and were slightly different only in single periods. For all the studied parameters except for Chl/Car ratio, interaction between sampling dates and sex was not statistically significant. Significant differences between the needles of different age were observed only in terms of the content of Chl b, MgPPIX, Pchlide, Chlide b, and Chl a/b ratio, and these differences were always caused by the current-year needles.

Przedstawione wyniki badań dotyczyły efektów stymulacji nasion światłem lasera He-Ne na zawartość barwników fotosyntetycznych w liściach skorzonery odmiany ‘Maxima’. Sprawdzono również, czy naświetlanie nasion może wpływać na długość czasu życia fluorescencji chlorofilu a w liściach i w ekstrakcie z liści. Materiał badawczy stanowiły liście roślin wyrosłych z nasion zebranych w latach 2009, 2010, 2011, 2012. Zdolność kiełkowania tych nasion wynosiła odpowiednio 50,8; 71,0; 93,0; 79,3%. Przed siewem nasiona poddano stymulacji elektromagnetycznej światłem lasera He-Ne o długości fali 632,8 nm i powierzchniowej gęstości mocy 3 mw∙cm–2 – w czasie 1, 5, 10 i 30 minut. Nasiona niestymulowane traktowano jako kontrolę. Zawartość chlorofilu a i b oraz karotenoidów w liściach skorzonery była większa w roślinach wyrosłych z nasion młodszych (zebranych w latach 2011 i 2012) niż z nasion starszych (zebranych w latach 2009 i 2010). Stymulacja nasion młodszych światłem lasera wpłynęła na zmniejszenie zawartości tych barwników w liściach. Czas życia fluorescencji chlorofilu w ekstrakcie z liści był dłuższy niż w liściach. Nie stwierdzono istotnego wpływu stymulacji laserowej nasion na czas życia fluorescencji chlorofilu w ekstrakcie z liści skorzonery. Parametr ten był wyższy w ekstrakcie liści roślin wyrosłych z nasion młodszych (ze zbioru w latach 2011, 2012) niż starszych (ze zbioru w latach 2009, 2010).

The present study aimed to identify the response of melon accessions and cultivars to salt stress in terms of ion exchange, enzyme activity, lipid peroxidation and photosynthetic pigment contents by mixture modelling. In mixture modeling, it is expected that the data set demonstrates a heterogeneous structure. This heterogeneity is characterized as unobservable heterogeneity. The data set’s heterogeneity produces severe deviations in the parameter assessments and the standard deviations. Heterogeneity is overcome when the data set separates itself into homogeneous sub-populations. Mixture modeling was performed using the Mclust mixture cluster program of the statistical software package R 5.2.3. Sub-populations were constructed by evaluating genotypes according to studied traits and correlation analysis was performed using the SPSS software package. The seedlings of 13 melon genotypes were harvested two weeks after salt application (0 mM or 50 mM NaCl) when symptoms of salt stress were observed. Nutrient contents and ratios (K, Ca, Na, K : Na and Ca : Na); superoxide dismutase (SOD), catalase (CAT) and ascorbate peroxidase (APX) activities malondialdehyde (MDA) chlorophyll a, chlorophyll b, total chlorophyll and carotenoid contents were measured. Mixture modeling and correlation analysis were used in evaluating the experimental data sets. Differences in responses to salt application were observed among genotypes. While all genotypes exhibited negative responses in terms of K : Na ratio, which is an important parameter of salt tolerance, the smallest decreases in K : Na ratios were observed in the YYU-11 (–57.09%) and YYU-4 (–58.78%) genotypes, indicating them to be the most tolerant to salt stress. In general, enzyme activity decreased in response to salt application, although the responses varied among genotypes, especially with regard to CAT and APX activity. The YYU-29 genotype was notable as the genotype with the highest K : Na ratio (1.79) as well as the smallest change in MDA content under salt stress.
