Tétel Szabadon hozzáférhető The atmospherical drought as a decisive factor of yield in the main sour cherry varieties of Hungary(2012-07-26) Lakatos, L.; Szabó, T.; Soltész, M.; Szabó, Z.; Sun, Z.; Nyéki, J.Atmospheric drought causes heavy diffi culties of water supply in most fruit species grown in Hungary, although the modern, intensive plantations are already equipped with irrigation. The use a dripping systems are widely applied, therefore nothing was done to avert the risk of atmospheric drought. In excessively dry seasons the reduction of yields is often due to atmospheric drought. Present study aims to utilise measured data of meteorological parameters (relative air humidity and temperature) to develop an index to characterise drought and measure its effect on fruit yield. Causes influencing yields are multiple. Phytosanitary problems are combined with defi cits of water supply. Water deficit of the soil is avoided by dripping irrigation, but the atmosphere is infl uenced by sprinklers only. Atmospherical drought increases the transpiration of the trees intensely and causes reduction of photosynthetic activity, consequently impairs the yield. Applying the index developed in a plantation of 6 sour cherry varieties grown in Hungary (Meteor, Nefris, Pándy, Újfehértói fürtös, Kántorjánosi, Debreceni bôtermô), we measured the specific yields (yield per volume of tree crown) during the period 1989–2011 using the meteorological database of the growing site. Additionally, other parameters characterising the drought are compared and searched for a method most reliable for judging the specific yielding capacity of sour cherry varieties. The results proved convincingly the utility of the index, especially for the varieties Pándy and Újfehértói fürtös. Comparison with other indices expressing the effects of drought revealed the superiority of our index, which will be applied in the future to express the risk of atmospheric drought.Tétel Szabadon hozzáférhető Cross section and longitudinal single-spin asymmetry A_L for forward W^{+/-}-->[mu]^{+/-}[nu] production in polarized p+p collisions at root{s}=510 GeV(2018) Majoros, Tamás; Sun, Z.; Ujvári, BalázsTétel Szabadon hozzáférhető Effect of over tree cooling irrigation on ‘Bosc’ pear orchards microclimate(2016-07-02) Lakatos, L.; Sun, Z.; Zhang, J.; Soltész, M.; Nyéki, J.Irrigation in some countries is a horticultural practice mainly used only to supply water. At the same time the use of microsprinklers have a powerful infl uence on the changes of temperature in orchards. When the air’s temperature is high (about 20 °C or higher) the evaporative cooling irrigation signifi cantly decreases the plants’ surface temperature and air temperature. The cooling effect is stronger when the air is dryer. By using cooling irrigation regularly, canopy temperature can be decreased so that the beginning of blooming can be delayed. Also if the blooming is early and frost probability is high, serious damages can happen in orchards. The benefi cial effect of cooling irrigation is the temperature reduction and frost protection. In March 2010, one month earlier than the expected blooming an irrigation system was established to produce anti-frost treatment and regulate the micro-climate of a Bosc pear orchard which belongs to the University of Debrecen (Hungary). The objective of sprinklers was to cool the air by increasing water evaporation and relative humidity. The position of the micro-sprinklers was planned in three levels (around the tree trunks, a few cm near to the soil surface, in the crown region and above the crown, a half meter higher). The results showed that the water sprayed in the orchard by micro-jets infl uenced decisively the temperature of the plantation. At higher temperatures (around 20 °C), the drop of temperature may attain 5–7 °C. A low relative humidity of the air may increase the relative effect. When water was applied at intervals of 15 minutes for ten times a day from 8 am to 18 pm, the air, fl owers and bud’s surface temperature could be kept low. At certain days when the temperature was higher than 10 °C, irrigation was used at night time in similar 15 minutes intervals, from 18 pm and 6 am. The beginning of bloom could be delayed for more than ten days. The Bosc pear variety blooming dynamics was characterized by a logistic curve in the treated as well as in the control plot. In the treated plot, the curve was steeper than in the control one in spite of the equal temperatures measured in the plots. Under Hungarian climatic conditions, the method was successfully used to delay blooming dates. The main result was the diminution of the frost damage in the spring that assured pears yields.Tétel Szabadon hozzáférhető J/psi and psi(2S) production at forward rapidity in p+p collisions at root{s} = 510 GeV(2020) Dávid, Gábor; Majoros, Tamás; Sun, Z.; Ujvári, BalázsTétel Szabadon hozzáférhető Kinematic dependence of azimuthal anisotropies in p+Au, d+Au, and He ^3He+Au at root{s_NN} = 200 GeV(2022) Imrek, József; Lovász, K.; Majoros, Tamás; Sun, Z.; Tarnai, G.; Ujvári, BalázsTétel Szabadon hozzáférhető Low-momentum direct-photon measurement in Cu + Cu collisions at root{s_NN}=200 GeV(2018) Majoros, Tamás; Sun, Z.; Tarján, Péter; Ujvári, Balázs; Vértesi, RóbertTétel Szabadon hozzáférhető Measurement of charged pion double spin asymmetries at midrapidity in longitudinally polarized p+p collisions at root{s} = 510 GeV(2020) Dávid, Gábor; Majoros, Tamás; Sun, Z.; Ujvári, BalázsTétel Szabadon hozzáférhető Measurement of J/[psi] at forward and backward rapidity in p + p, p + Al, p + Au, and ^3He +Au collisions at root{s}NN = 200 GeV(2020) Dávid, Gábor; Lovász, K.; Ujvári, Balázs; Majoros, Tamás; Sun, Z.; Tarnai, G.Tétel Szabadon hozzáférhető Measurement of jet-medium interactions via direct photon-hadron correlations in Au+Au and d+Au collisions at root{s_NN} = 200 GeV(2020) Firak, Daniel Scheres; Imrek, József; Majoros, Tamás; Sun, Z.; Tarján, Péter; Ujvári, Balázs; Vértesi, RóbertTétel Szabadon hozzáférhető Nonperturbative transverse-momentum-dependent effects in dihadron and direct photon-hadron angular correlations in p+p collisions at root{s} = 200 GeV(2018) Lovász, K.; Majoros, Tamás; Sun, Z.; Tarnai, G.; Ujvári, BalázsTétel Szabadon hozzáférhető Nonperturbative-transverse-momentum broadening in dihadron angular correlations in root{s_NN}=200 GeV proton-nucleus collisions(2019) Dávid, Gábor; Lovász, K.; Majoros, Tamás; Sun, Z.; Tarnai, G.; Ujvári, BalázsTétel Szabadon hozzáférhető Nuclear Dependence of the Transverse Single-Spin Asymmetry in the Production of Charged Hadrons at Forward Rapidity in Polarized p+p, p+Al, and p+Au Collisions at root{s_NN} = 200 GeV(2019) Dávid, Gábor; Lovász, K.; Majoros, Tamás; Sun, Z.; Tarnai, G.; Ujvári, BalázsTétel Szabadon hozzáférhető Nuclear-modification factor of charged hadrons at forward and backward rapidity in p+Al and p+Au collisions at root{s_NN} = 200 GeV(2020) Dávid, Gábor; Lovász, K.; Majoros, Tamás; Sun, Z.; Tarnai, G.; Ujvári, BalázsTétel Szabadon hozzáférhető Polarization and cross section of midrapidity J/psi production in p+p collisions at root{s} = 510 GeV(2020) Firak, Daniel Scheres; Majoros, Tamás; Sun, Z.; Ujvári, BalázsTétel Szabadon hozzáférhető Probing Gluon Spin-Momentum Correlations in Transversely Polarized Protons through Midrapidity Isolated Direct Photons in p+p Collisions at root{s} = 200 GeV(2021) Lovász, K.; Majoros, Tamás; Sun, Z.; Tarnai, G.; Ujvári, BalázsTétel Szabadon hozzáférhető Production of [pi]^0 and [eta] mesons in Cu+Au collisions at root{s_NN}=200 GeV(2018) Majoros, Tamás; Sun, Z.; Ujvári, BalázsTétel Szabadon hozzáférhető Production of bb at forward rapidity in p+p collisions at root{s} = 510 GeV(2020) Firak, Daniel Scheres; Majoros, Tamás; Sun, Z.; Ujvári, BalázsTétel Szabadon hozzáférhető Production of pi^0 and eta mesons in U+U collisions at root{s_NN} = 192 GeV(2020) Firak, Daniel Scheres; Majoros, Tamás; Sun, Z.; Ujvári, BalázsTétel Szabadon hozzáférhető Relations of phenometrical indices of apple fruits with weather variation in the assortment of varieties of an apple gene bank(2012-07-26) Lakatos, L.; Szabó, T.; Szabó, Z.; Soltész, M.; Sun, Z.; Nyéki, J.The purpose of phenometry is to examine the measurable parameters of the plants in order to follow up the consequences of weather processes. We should fi nd the reasons, why the diameter of fruits grows larger in one season and smaller in the next. Variation may occur as a response to insuffi cient provision of water or nutrients, but also because of pathological effects and of extremely high or low temperatures, moreover, of extraordinary heavy fruit load. There are phenometrical characteristics, which consider the fi nal consequences (density of fl owers, fruits set, drop of fruits), whereas other parameters could be followed up (size, length and width of fruits) as the dynamic components of growth. The quantitative parameters of growth are functionally related to each other, where the weather conditions, soil humidity and nutrients are on the input side, thus it is possible to model the growth of fruits as a function of the environment. Initially, the relations between the main weather variables and the phenometrical data have to be cleared. In the present study, the interactions between the mentioned phenomena are presented and numerically defi ned.Tétel Szabadon hozzáférhető The role of meteorological variables of blossoming and ripening within the tendency of qualitative indexes of sour cherry(2010-01-03) Lakatos, L.; Szabó, T.; Sun, Z.; Soltész, M.; Szabó, Z.; Dussi, M. C.; Nyéki, J.We analyzed the relationship to sour cherry quality parameters of average temperature, maximum temperature, minimum temperature, night and day-time temperature, precipitation and climatic water balance variables. Three cultivars of sour cherry were included in the selection: “Debreceni bôtermô”, “Kántorjánosi”, and “Újfehértói fürtös”.We conducted regression analyzes on the three varieties, but present only those that proved to be the best fit.We couldn’t find any significant differences in the weather tolerance of the varieties. The data base of sour cherry quality parameters covers the 1998 to 2008 intervals. The researched parameters were the following: dry matter content (%), sugar content (%), C-vitamin (mg), total acid content (%). Maximum temperature, the difference of night and day-time temperature and minimum temperature all have a significant correlation with the investigated quality parameters of sour cherry. Minimum temperature shows a quadratic relationship with sugar content, while night and day-time temperature differences show the same with dry matter content. The other weather parameters had a linear correlation with the quality parameters of sour cherry. The research results show that an increasing amount of precipitation causes decreasing tendency in total acid content of sour cherry, so that increasing temperature has a positive influence on total acid content. Big differences in night and day-time temperature also has positive effects on the dry matter and sugar content of sour cherry while the amount of precipitation has a negative effect. High minimum temperatures cause decreasing sugar content respiratory energy losses are significant if dawn temperatures do not drop considerably.A more favourable climatic water balance has a positive effect on vitamin C content in cases of a large negative water balance, vitamin C content is generally low.
