Response of alternate bearing of âBadamy sefidâ Pistachio cultivar to foliar application of some macro and micro elements
Response of âBadamy sefidâ Pistachio trees to spraying of fertilizer was studied over two years (2006â2007). The boron and zinc fertilizer were used just on swelling time of female flower bud in compare to no fertilization (control). Also nutritional solution combined of nitrogen (400 ppm), phosphorus (P2O5) (380 ppm), potasium (K2O) (520 ppm), Fe (5 ppm), Cu (2 ppm), Zn (2 ppm), Mn (2 ppm) in 1000 liter water per hectare sprayed at first week of May, third week of June and July). The concentration of some macro and micro elements in flower bud and in leaves, also productivity (g/shoot sectional area) mean nut weight, fresh weight of nut per cm2 branch cross sectional area, blanks nuts %, non-split nut %, new shoot growth length after cessation of growth and remained flower bud (%) at the next spring were recorded for the different treatments. The results showed that boron and zinc concentration increased in the bud of sprayed trees in compare to control. Application of nutritional solution decreased the flower bud abscission, also resulted in increased vegetative growth, nut weight, and productivity of trees. In conclusion, spraying of fertilizers in the suitable time to the pistachio trees might be a useful method in decreasing flower bud abscission and mitigating the alternate bearing

Comparison of varying pollen source on productivity of sour cherry (Prunus cerasus L.) cultivars
Fruit set of five sour cherry cultivars (âĂjfehĂ©rtĂłi fĂŒrtösâ, âĂvaâ, âPetriâ, âPĂĄndy 279â and âCsengĂŽdiâ) of eight years-old treesgrown in ĂjfehĂ©rtĂł, 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 PĂĄndy 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 (âĂrdi bĂŽtermĂŽâ, âDebreceni bĂŽtermĂŽâ, âKĂĄntorjĂĄnosiâ, âĂjfehĂ©rtĂłi fĂŒrtösâ,âĂvaâ, âPetriâ âOblocsinszkaâ, âPandy 279â and âCsengĂŽdiâ) of eight years-old trees grown in ĂjfehĂ©rtĂł, 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 âOblocsinszkaâ by 32.6% the highest fruit set, while âDebreceni bĂŽtermĂŽâ is very similarto âPandy279â 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 onâPandy279â (92.4%) very similar to âĂvaâ (90%) while the lowest fruit drop observed in âOblocsinszkaâ (71.5%
Levels of some micronutrient in dried and fresh fruit samples of apricot cultivars
Concentration of Boron (B), Copper (Cu), Iron (Fe), Magnesium (Mg), Manganese (Mn) and Zinc (Zn) was analyzed in fresh and dried fruit samples of âJumbo cotâ, âTom cotâ, âGold strikeâ, âGold barâ, âBergeronâ, âBergrougeâ, âSweet cotâ, âYellow cotâ and âZebraâ apricot cultivars. Concentration of the studied elements was strongly affected by cultivars. B, Cu, Fe, Mn and Zn content of âTom cotâ was significantly higher than other cultivars. âGold strikeâ had the highest amount of Mg. Similar tendency was observed in âZebraâ and âSweet cotâ where Mn content was significantly higher than the other element contents

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 â H2O2 digester mixture and inductively coupled plasmaâatomic 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
