Comparison of varying pollen source on productivity of sour cherry (Prunus cerasus L.) cultivars

Fruit set of five sour cherry cultivars (‘Újfehértói fürtös’, ‘Éva’, ‘Petri’, ‘Pándy 279‘ and ‘Csengôdi’) of eight years-old treesgrown in Újfehértó, located in the Eastern north part of Hungary have been studied over two years (2008 & 2009). Following reciprocallycross-pollination, free-pollination, self-pollination (autogamy) artificial self-pollination (geitonogamy) were studied. The results show thatboth maternal and paternal parent cultivates had significant effects on the percentage fruit set. Significant differences have been found in fruitset among years and among pollination treatments. Fruit set of free-pollinated Pándy 276 cultivar was low and seasonally highly variable. Theyield of this cultivar on self-pollinated flowers was nearly 0%, and in this treatment the maximum yields did not reach 10% in any of theexamined cultivars. There was no significant relationship in the fruit set of free-pollination and natural self-pollination treatments

Terminology of fruit set and fruit drop of sour cherry cultivars

Fruit set and fruit drop rates of 9 sour cherry cultivars (‘Érdi bôtermô’, ‘Debreceni bôtermô’, ‘Kántorjánosi’, ‘Újfehértói fürtös’,‘Éva’, ‘Petri’ ‘Oblocsinszka’, ‘Pandy 279’ and ‘Csengôdi’) of eight years-old trees grown in Újfehértó, located in the Eastern north part ofHungary which grafted on Prunns mahaleb have been studied. Significant differences have been found in fruit set among cultivars. Theaverage percentage of fruit set was 18.3%, which the ‘Oblocsinszka’ by 32.6% the highest fruit set, while ‘Debreceni bôtermô’ is very similarto ‘Pandy279’ showed lowest (12%) fruit set. Seasonal changes of fruit set and drop shows that there are four abscission peaks. The first fruitabortion wave appears during second week after pollination Thereafter, the second and third dropping period was found during the third andforth weeks after pollination. The forth abscission happened on the forth week after pollination. The highest fruit drop happened on‘Pandy279’ (92.4%) very similar to ‘Éva’ (90%) while the lowest fruit drop observed in ‘Oblocsinszka’ (71.5%

Simultaneousness of reproductive organs of sour cherry cultivars adaptable to Iranian climatic condition

Observations were made on simultaneousness of pollen shedding and stigma viability ratio, to clarify the phenology of reproductive organs of nine economically important sour cherry (Prunus cerasus L.) cultivars (‘Érdi bôtermô‘, ‘Debreceni bőtermő‘, ‘Csengődi‘, ‘Kántorjánosi 3‘, ‘Újfehértói fürtös‘, ‘Petri‘, ‘Eva‘, ‘Oblascinszka‘, and ‘Pándy 279’). The main aim was investigation the possible influence of environmental cues in timing and development of phenophases and also responses of different cultivars to seasonal cues. Likely effects of climatic changes on phenological development patterns were also considered. Results showed important aspects of the reproductive biology of sour cherry flowers. The amplitude of the phenophase “beginning of blossoming” between cultivars did not exceed 6 days. There is a maximum 3 day difference in the blooming length of different directions in each cultivar. ‘Pándy 279‘ showed high variability when the position of flowers changed on the tree shoots. ‘Újfehértói fürtös‘ was stable in all four directions of the tree. The pollen shedding period and stigma viability ratio were synchronous. Pollen shedding phenomenon simultaneously occurred with the secretary activities of stigmas in all examined cultivars. Distribution of pollen shedding over the secretary activity of stigmas is almost good. In all five cultivars maximum pollen shedding occurred when the temperature was high during the day. In general the results of this experiment and our previous studies clearly demonstrate that the Pándy groups not recommended for plantation in new orchards of Iran

Hazardous element content and consumption risk of 9 apricot cultivars

The heavy metals pollution is one of the problems that arise due to the increased uses of fertilizers and other chemicals to meet thehigher demands of food production for human consumption. In order to assess possible health risk of apricot (Prunus armeniaca L.)consumption, levels of Arsenic, Cadmium, Mercury and Lead were determined in fresh and dried samples of "Jumbo cot", "Tom cot", "Goldstrike", "Gold bar", "Bergeron", "Bergarouge", "Sweet cot", "Yellow cot" and "Zebra" apricot cultivars. Wet digestion of samples withconcentrate HNO3 – H2O2 digester mixture and inductively coupled plasma–atomic emission spectroscopy was used. Highest content of As,Cd, Hg and Pb among all cultivars, were 0.5, 0.04, 1.5 and 0.5mg/kg of dried apricot samples. Fresh fruit samples also contain 0.2, 0.016, 0.6and 0.2 mg/kg of Arsenic, Cadmium, Mercury and Lead respectively. Daily intake of metals, hazard quotient and health risk index to revealhealth risk possibility of dried and fresh fruits consumption were calculate and compared

First evaluation of fruit quality of some new and old sour cherry cultivars in Hungarian climatic condition

Indeed, in the last decade a large number of new sour cherry cultivars with new notable flavor characteristics have been released.There is no enough information related to qualitative characteristics which consistently segregated based on their predominant sensorycharacteristics. The present study carried out at tow consecutive years (2008 and 2009) and examined some qualitative characters which arethe main importance in the specialty cherries trade, The main objective was to determine fruits quality of Érdi bôtermô, Oblacsinszka,Debreceni bôtermô, Csengôdi, Pándy 279, Éva, Kántorjánosi, Újfehértói fürtös and Petri sour cherry cultivars. Changes observed in majorcharacteristics such as fruit detachment force, width, length, weight, peduncle length, flesh firmness, brix, citric acid, Suger/acid ratio and pitweigh.While observed no change in flesh/pit ratio and Coordinate of colour (X*, y*, x*), hue angle and chroma value, in different years. Inall measured factors, there was significant difference between selected cultivars of sour cherry fruit. Debreceni bôtermô showed higher valuesof fruit detachment force in 2008, while had the lover of fruit detachment force in 2009. Fruit firmness of “Érdi bôtermô” were monitored atlover value in both 2-year

Reproductive biology traits affecting productivity of sour cherry

The objective of this work was to evaluate variability in reproductive biology traits and the correlation between them in genotypes of 'Oblacinska' sour cherry (Prunus cerasus). High genetic diversity was found in the 41 evaluated genotypes, and significant differences were observed among them for all studied traits: flowering time, pollen germination, number of fruiting branches, production of flower and fruit, number of flowers per bud, fruit set, and limb yield efficiency. The number of fruiting branches significantly influenced the number of flower and fruit, fruit set, and yield efficiency. In addition to number of fruiting branches, yield efficiency was positively correlated with fruit set and production of flower and fruit. Results from principal component analysis suggested a reduction of the reproductive biology factors affecting yield to four main characters: number and structure of fruiting branches, flowering time, and pollen germination. Knowledge of the reproductive biology of the 'Oblacinska' genotypes can be used to select the appropriate ones to be grown or used as parents in breeding programs. In this sense, genotypes II/2, III/9, III/13, and III/14 have very good flower production and satisfactory pollen germination
