In tomato fruits, chlorophyll, lycopene and ß-carotene are mostly responsible for the color. During ripening of tomato fruits, the color of the pericarp changes from green to red as chlorophyll is degraded and carotenoids accumulate. These changes are associated with an increase in respiration and ethylene production. Carotenoid biosynthesis pathway in plants can be disturbed by herbicide fluridone (1-methyl-3-phenyl-5-[3-trifluoromethyl(phenyl)]- 4(1H)-pyridinone), which inhibits the activity of phytoene desaturase, an enzyme responsible for conversion of phytoene to phytofluene. Fluridone is also used as an inhibitor of biosynthesis of abscisic acid (ABA) and strigolactones, and it reduces chlorophyll production in plants. In our research we studied the effect of fluridone on some physiological parameters, such as color, firmness, ethylene production, lycopene and chlorophyll content during ripening of the tomato fruit. Tomato plants cv. Altadena (Syngenta) were cultivated in a greenhouse in controlled temperature and both immature and mature fruits were used for the experiments, performed between August and November 2016. Fluridone at concentrations of 0.1% and 1.0% in lanolin paste was applied as a 2-3 mm stripe from the top to the base of tomato fruits, and as a control a stripe of lanolin was applied in the same way on the opposite side of the fruits. Fluridone at a concentration of 1.0% greatly inhibited lycopene accumulation in the pericarp of tomato fruits from the treated side. The measurements of fruit firmness have shown no significant differences between firmness of the part of the tomato fruits treated with fluridone, and the non-treated ones. Tomato fruits treated with fluridone produced amounts of ethylene similar to those found in control tissues on the opposite side of the same fruit. Fluridone delayed chlorophyll degradation in tomato fruits. The metabolic significance of these findings is discussed with the role of carotenogenesis inhibition in tomato fruit ripening.

In order to evaluate the yield, yield components and some physiological and qualitative traits of corn treated with nitrogen fertilizers (biological, chemical and integrated), a field experiment was conducted at the Agricultural Research Station of Khorramabad during 2016 growing season. Treatments were arranged in a complete randomized block design with four replications. Experimental treatments consisted of 100% chemical fertilizer (urea), bio-fertilizer (nitroxin), integration of bio-fertilizer + 25% chemical fertilizer, integration of bio-fertilizer + 50% chemical fertilizer, integration of bio-fertilizer + 75% chemical fertilizer and the control. Results showed that the effect of different treatments of fertilizers on all measured traits, except for number of rows in each ear and carotenoids, was significant. The results indicated that integration of bio-fertilizer + 75% chemical fertilizer affected the highest grain yield (9.31 t ha–1), dry biological yield (20.96 t ha–1), number of kernels in each row (41.67), plant height (201.02 cm), hectoliter weight (0.82 g cm–3), chlorophyll b (0.43 mg g–1 FW), total chlorophyll (1.1 mg g–1 FW) and leaf area index (LAI) (4) and there was no significant difference among this treatment and 100% chemical fertilizer (N) and integration of bio-fertilizer + 50% chemical fertilizer treatments in all measured traits. The greatest harvest index (45.8) and grain protein-content (9.1%) resulted from the integration of biofertilizer + 50% chemical fertilizer treatment. Also the highest 1000-grains weight (281.13 g) and chlorophyll a (0.66 mg g–1 FW) were caused by 100% chemical fertilizer (urea) treatments. Results showed that integration of bio-fertilizer + chemical fertilizer could be considered as a means to reduce the consumption of chemical fertilizers for sustainable agriculture.

W pracy oceniano zmienność fenotypową u 10 linii wsobnych żyta ozimego wyselekcjonowanych z różnych odmian uprawnych i form hodowlanych. Różnice pomiędzy liniami dotyczyły cech związanych z produktywnością roślin: długości źdźbła i kłosa, krzewistości, liczby ziaren z kłosa, masy 1000 ziaren, plonu ziarna z rośliny, intensywności fotosyntezy netto i transpiracji, a także liczby chloroplastów w mezofilu oraz zawartości chlorofilu. Wybrane linie wsobne żyta charakteryzowały się dużym zróżnicowaniem pod względem wymienionych cech i wykazywały wartości skrajne. Spośród analizowanych linii wyróżniała się linia J74, która miała najwyższe wartości dla większości cech (długość kłosa, liczba ziaren z kłosa i roślin, ulistnienie oraz aktywność fotosyntetyczna), co predysponuje ją do zastosowania w hodowli wysokoproduktywnych, heterozyjnych odmian żyta.

In this investigation the phenotype variability was assessed in 10 inbred lines of winter rye, derived from different varieties and breeding forms. Moreover, these lines were characterized by a significant variability of the analyzed features: length of the stalk and spike, number of stems, number of grains per spike, weight of 1000 grains and grain weight per plant, net photosynthetic rate and transpiration rate as well as chloroplast number and also chlorophyll content. The lines chosen for research were characterized by high trait variations and showed extreme values. Among the analyzed lines, the line J74 had the best values in most traits such as: length of the spike, number of grains per spike and plant, leaves of plant and photosynthetic activity. This linę is, therefore, predisposed to be used in breeding of highly productive heterosis varieties of rye.

New early potato cultivars were assessed in respect of their yield increase rate. Moreover, the morphological and physiological plant traits correlated with high level of yielding were determined. Two Polish cultivars (Gracja and Korona) and two foreign (Molly and Rosalind - German) cultivars were chosen to investigations. The field experiment was conducted in years 2003-2005 in split-plot arrangement and four replications. During growing period, every week after the end of plant emergence the above-ground part of plants and tuber yield were measured. The following indices were calculated: leaf area index (LAI), leaf stem ratio (LSR), specific leaf area (SLA). The final yield of tested cultivars was highly correlated with mass of leaves produced by plant and LAI index. The Korona cultivar was characterized by the highest yield and yielding stability. The tolerance of potato cultivars to cold stress during the first growing period may be higher in case of the local cultivars than in case of the foreign ones but this thesis needs the further studies on larger number of cultivars to be confirmed.

Przeprowadzono ocenę polskich i zagranicznych wczesnych odmian ziemniaka pod względem tempa przyrostu plonu oraz określono morfologiczno-fizjologiczne cechy roślin skorelowane z wysokim poziomem plonowania. Do badań wybrano dwie odmiany polskie - Gracja i Korona i dwie niemieckie - Molly i Rosalind. Doświadczenie polowe przeprowadzono w latach 2003-2005 metodą losowanych bloków w czterech powtórzeniach. W okresie wegetacji w odstępach 1-tygodniowych od zakończenia wschodów wykonywano pomiary części nadziemnej roślin i plonu bulw. Obliczano wskaźniki: LSR, LAI, SLA. Plon końcowy badanych odmian był najbardziej dodatnio skorelowany z masą wytworzonych przez roślinę liści oraz ze wskaźnikiem LAI. Odmiana Korona wyróżniała się najwyższym plonem i najwyższą tolerancją na niekorzystne warunki termiczne w okresie wegetacji. Może być ona wyższa w przypadku odmian lokalnych aniżeli odmian zagranicznych, ale dla potwierdzenia tej tezy potrzebne są dalsze badania na większej liczbie odmian.

Propagation conditions of bedding plants can eliminate or reduce the possibility of AMF inoculation of the root system during greenhouse production. Due to the ability of AMF to increase plant growth the effects of AMF and CO₂ enrichment on rooting and some physiological traits of geranium and osteospermum cuttings were investigated. AMF and CO₂ enrichment increased leaf number and fresh and dry weights of osteospermum shoots. Mycorrhization also significantly increased the length and fresh and dry weights of osteospermum roots formed in CO₂ enriched atmosphere but it did not affect root system developed in ambient atmosphere. AMF increased the length and fresh weight of geranium roots, irrespectively of CO₂ concentration, and dry weight of roots in CO₂ enriched atmosphere. Transpiration and stomatal conductance values were higher in inoculated osteospermum at higher CO₂ concentration. Mycorrhization and CO₂ enrichment increased photosynthetic activity of garden geranium leaves and this effect was connected with the increased ratio of variable to maximum chlorophyll fluorescence (Fv/Fm).

W czasie produkcji w szklarniach warunki rozmnażania roślin rabatowych mogą eliminować lub zmniejszać możliwość inokulacji korzeni przez grzyby wywołujące mikoryzę arbuskularną (AMF). Ponieważ mikoryzacja może wpływać korzystnie na wzrost roślin, badano wpływ inokulacji AMF i dokarmiania CO₂ na ukorzenianie i niektóre cechy fizjologiczne sadzonek pelargonii rabatowej i osteospermum. Inokulacja AMF i dokarmianie CO₂ powodowały wzrost liczby liści oraz świeżej i suchej masy części nadziemnej sadzonek. Mikoryzacja wpływała znacząco na długość oraz świeżą i suchą masę systemu korzeniowego osteospermum w warunkach podwyższonego stężenia CO₂ w atmosferze, ale nie wpływała na wzrost systemu korzeniowego sadzonek niedokarmianych CO₂. Mikoryzacja wpływała także korzystnie na długość i świeżą masę systemu korzeniowego pelargonii rabatowej niezależnie od stężenia CO₂ oraz na suchą masę korzeni pelargonii w warunkach podwyższonego stężenia CO₂. Transpiracja i przewodnictwo szparkowe były większe u inokulowanych sadzonek osteospermum niż u nieinokulowanych w większym stężeniu CO₂. Mikoryzacja i dokarmianie CO₂ powodowały wzrost intensywności fotosyntezy u pelargonii, co było związane ze wzrostem stosunku zmiennej do maksymalnej fluorescencji chlorofilu (Fv/Fm).

This study was conducted to determine the impact of heat stress on some physiological and endocrine traits in Saanen goats raised under Mediterranean climate conditions. The effects of thermal stress on heart rate (HR), respiration rate (RR) and rectal temperature (RT) on plasma total trii-odothyronine (T3), thyroxine (T4), Cortisol (C), and HSP70 concentrations were evaluated on twenty two Saanen goats of different ages in the second week of April 2013, July 2013, October 2013 and January 2014. Climatic data such as temperature (°C) and relative humidity (%) were recorded from Spring 2013 to Winter 2014. Live body and BCS values were also recorded during this period. The physiological parameters above were measured twice on each experiment day (morning and afternoon) in all seasons. Blood samples were collected in each afternoon of the experiment day to analyze T3, T4 C, and HSP70. All data were analyzed. According to the values of rectal temperature (RT), it was estimated that the goats were under extreme heat stress only in the summer season. The heart rate (HR) values in the winter season for morning and noon periods were found statistically significant (p < 0.05). The average respiratory rate (RR) in the spring season was found significantly lower. On the other hand, the RR for the noon period in the summer was higher than in the fall and winter seasons (p < 0.05). There was a significant difference (p < 0.05) between summer and fall seasons for C values. The highest value (96.62 ng/ml) was obtained in spring, whereas the lowest (60.58 ng/ml) in the fall. T3 levels in the fall and winter were found to be statistically significant (p < 0.05). They were the highest in the winter and spring, and the lowest in fall. T4 and T4/T3 levels in the winter were found to be statistically higher than in other seasons (p < 0.05). The lowest value for T4 was found in the fall and for T4/T3 in summer. Mean HSP70 value in spring was found to be statistically low (p < 0.05). The changes in THI values in different seasons, particularly between mornings and afternoons, indicated that thermal stress was evident, and that the animals became resistant to it eventually. The fluctuations of the C, T3, T4 and HSP70 values were indicators of the animals’ reaction to thermal stress. The THI values in spring, which were between 16 and 18 THI, may be considered within the ideal comfort zone for goats. It was observed that Saanen goats were able to adapt to seasonal weather changes in the environmental conditions of the region.
