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.

The objective of this study was to determine the effect of varied (280 and 420 kg NPK ha⁻¹) soil and foliar application of mineral fertilizers (Basfoliar 12-4-6, ADOB Mn, Solubor DF) on the yield and qualitative traits of late-maturing potato variety Jasia. An exact, two-factorial field experiment was conducted by the randomized split-plot method, in four replications, in the years 2004–2006 in the Masurian Lakeland. The total yield of potato tubers, the content and yield of starch, and the grain size fractions of starch were determined in the study. The applied fertilizers, regardless of their rates, had no significant effect on the total yield of potato tubers and starch yield. The starch content of potatoes was affected by soil fertilization. An increase in the rate of mineral fertilizers from 280 to 420 kg NPK ha⁻¹ caused a decrease in starch content. Large starch grains (> 40 μm in diameter), which enable to reduce the overall loss during the removal of starch from the potato pulp, dominated in the experimental material.

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.

The study dealt with the quantitative and qualitative estimation of tuber yields for three potato cultivars cultivated and harvested from the plots where three fertilizer combinations were applied plus control object. For each experimental factor, after harvesting of the tuber yield, the following features were determined: yield structure, the contents of dry matter and nitrates, percentage of tubers’ infection with potato scab and Rysoctonia solari; the tubers were selected and divided into well shaped, misshaped and mechanically damaged. All these features were estimated just after harvest and during storage. The investigations were conducted in three replications for each experimental factor using 5 kg samples of tubers during storage season 2005/2006. The samples were stored in a storage chamber under controlled air temperature and relative humidity (4-6°C and 90-95%, respectively). During storage, in 4 measuring terms of 40 days’ cycle, the mass losses and disease caused losses were estimated. In malformed and damaged tubers stronger infection with potato scab and Rysoctonia solari as well as the higher mass losses and disease caused losses were observed in comparison to well-shaped tubers. Obtained results showed significant relationships among the share of misshaped (defective) tubers in yield, an index of mechanical tuber damages, mass losses, infection of the tubers with potato scab and long-term storage mass losses.

Wyroby ciastkarskie stanowią popularną wśród konsumentów grupę produktów spożywczych. Na rynku istnieje gama produktów otrzymanych głównie z mąki pszennej i z dodatkiem płatków bądź otrąb zbożowych, natomiast nie spotyka się ciastek otrzymanych w całości z mąki amarantusowej, dyniowej, jęczmiennej czy żytniej. Celem pracy było porównanie cech sensorycznych, akceptowalności konsumenckiej i właściwości mechanicznych ciastek kruchych wypieczonych z handlowej mąki amarantusowej, jęczmiennej, dyniowej i żytniej, z ciastkami otrzymanymi z mąki pszennej. W ciastkach oznaczono twardość, wykonując test trójpunktowego łamania, przy użyciu analizatora tekstury TA.XT2plus. Przeprowadzono ocenę sensoryczną, badania akceptowalności konsumenckiej przy użyciu 9-stopniowej skali hedonicznej, a także profil smakowo-zapachowy przy użyciu skali graficznej. Zastąpienie mąki pszennej przez inne mąki wpłynęło na zmianę parametrów tekstury i walorów organoleptycznych ciastek. Zamiana mąki pszennej na amarantusową i dyniową spowodowała zmniejszenie twardości i wilgotności ciastek. Ciastka sporządzone z mąki jęczmiennej i żytniej charakteryzowały się zbliżoną twardością w dniu wypieku i podczas początkowego okresu przechowywania. Zasadnym jest wprowadzenie do produkcji ciastkarskiej mąki dyniowej, jęczmiennej czy żytniej jako substytutu mąki pszennej.

Combining abilities of nine tetraploid potato parental forms for general appearance of tubers, enzymatic browning and fry colour after cold storage (4-6°C) were evaluated at Research Division Młochów of Plant Breeding and Acclimatization Institute. The progeny test comprised 18 families from hybridization of six maternal forms (M-64, PS-1753, M-62775, M-62812, M-62819, M-62820) with three paternal forms (PS-1742, M-16, cv. Panda). The key characters of parental lines used in above mentioned hybridization were light colour of fry product and resistance to PVY. Each parental combination was represented by 60 unselected seedlings grown on the non-irrigated field in 2004. Analysis of variance revealed significant differences among studied families for frequency of individuals with good tuber morphology, enzymatic browning and fry colour after cold storage (4-6°C). Out of nine tested parental forms the M-62819, PS-1742, and PS-1753 were the best at transmitting light fry colour (4-6°C) to their offspring. In addition M-62819 and PS-1742 have increased frequency of individuals with good tuber morphology. The clone M-62775 was identified as the parent with significant positive GCA effect for enzymatic browning and thus can be utilized in a breeding programmes for raw dried potato products.

The effects of different nitrogen fertilization rates (100, 125 kg N·ha⁻¹) on the yield and qualitative characters of one German (Romula) and two Dutch (Lady Claire, Saturna) chip potato cultivars were studied. Field experiment was conducted within 2003-2005 in NE Poland, by using the randomized block and split-plot method, in four replications. The total tuber yield, yield structure, starch content, starch yield, concentration of reducing sugars, suitability of potato tubers for frying, as well as gross and marginal fertilization efficiency, were determined. The growing seasons 2003 and 2005 were classified as dry and warm, whereas the year 2004 was described as wet and warm. The highest total and marketable tuber yields and the highest starch yield were attained in case of the medium-early cultivar Romula. Romula cv. was also characterized by the lowest proportion of small tubers (< 40 mm) and the highest proportion of large tubers (> 60 mm). This cultivar responded to an increase in nitrogen rate by the highest gross productivity. The medium-late Saturna cultivar showed the highest starch content, at highest proportion of small tubers (< 40 mm), lowest proportion of large tubers, and the lowest marketable tuber yield. The early Lady Claire cultivar provided the lowest total tuber yield as well as the lowest yield and content of starch. Both, the concentration of reducing sugars and suitability for frying were satisfactory in all tested potato cultivars. The effect of nitrogen fertilization on total and marketable tuber yield, and starch yield was not confirmed by statistical analysis. Only in 2004 the higher nitrogen rate (125 kg N·ha⁻¹) significantly increased the starch content in tubers.

Celem badań było określenie wpływu płci na wybrane parametry tekstury i cechy sensoryczne mięśni piersiowych. Materiał stanowiły kurczęta średnio rosnące, mieszańce CCZk utrzymywane do 63. dnia życia. Określono skład podstawowy za pomocą spektrometrii w bliskiej podczerwieni, pH, wodochłonność, wyciek termiczny, wykonano pomiar parametrów barwy, przeprowadzono test przecinania oraz ocenę semi-konsumencką metodą skalowania. Uzyskane wyniki badań wskazują, iż w ocenie konsumenckiej różnice w jakości mięsa drobiowego wynikające z dymorfizmu płciowego były nieznaczne, co zostało potwierdzone statystycznie. Lepszą jakością ogólną wyróżniały się jednak mięśnie piersiowe kur (P < 0,05). Wykazano ponadto korelację między wartościami uzyskanymi w ocenie semi-konsumenckiej a tymi wybranymi z pomiarów instrumentalnych. Przeprowadzona analiza klasyfikuje mięśnie piersiowe kurcząt do grupy mięs o wysokich walorach smakowych i kulinarnych.

On medium heavy soil, in 2002-2004, the experiments were carried out to determine the optimum nitrogen fertilization rates for early potato cultivars and the effect of fertilization on yield quality and storage durability of the potato tubers. The highest commercial yield was obtained for Denar cv. (51.7 t·ha⁻¹), the lesser for Felka and Korona cvs. and the least for Gracja cv. (35.1 t·ha⁻¹). The highest requirements in relation to nitrogen fertilization showed Felka and Gracja cultivars, tittle less - Denar and Korona cvs. Most susceptible to the common scab and hust internal spots was Felka potato cultivar whereas the Gracja and Korona cvs. showed the highest number of tubers whit hollow centre. As the nitrogen fertilization rates increased Denar and Korona potato cultivars cumulated increasing amounts of nitrates in the tubers. However, no effect of nitrate fertilization rates on the storage durability of tubers was observed.

For many decades potato production has been one of most important directions in Polish agriculture. Actually, the most important task in production of edible and starchy potato as well as the potato for processing is to obtain high tuber quality and optimum yields. Required quality characteristics are formed mainly by cultivation practices and knowledge, skillfully applied under conditions of given farm. Important cultivation factors affecting the level and quality of potato yield include: soil tillage, organic and mineral fertilization, practices connected with planting (preparation of seed potatoes, term of tuber treatment, planting density, row spacing, potato plant protection against agrophages, irrigation, preparation for harvest and harvesting). The operations should be carried out carefully and properly fitted to utilization direction of the potatoes.
