The quality of `Ron's Seedling', `American Bing', and `Lambert' sweet cherry drupes was not affected by irradiation doses up to 300 to 1000 gray. Peduncle discoloration increased in `Ron's Seedling' cherries when irradiated at 600 and 1000 gray. A dose of 75 gray prevented adult eclosion of more than 1300 Queensland fruit fly (Dacus tryoni, Froggatt). Larvae treated at the third instar were the least susceptible to gamma irradiation. The results indicated that gamma irradiation is a feasible quarantine treatment against D. tryoni without impairment to the quality of cherries.

Postharvest Treatment

Sweet cherry shows a limited storage time mainly due to incidence of decay and a fast loss of sensory quality of the fruit. Sweet cherries may be damaged seriously by fungal pathogens for a long storage period. For the control of postharvest diseases, the use of chemicals as fungicides has been applied to sweet cherries. In this paper, a kind of antimicrobial packaging, based on our patent , which can release SO2fungicide has been used as postharvest treatment to protect the sweet cherry quality. Cherries quality during storage was determined, and results suggest that SO2 fungicide packaging showed benefits in terms of lower weight loss, lowerSuperscript textdecay rate and maintenance of fruit firmness compared with the control one.

Gamma Ray Irradiation

Snake fruit (Salacca zalacca) is a unique fruit and it has decadent prospects to be developed as an export commodity. Nevertheless, oriental fruit fly, Bactrocera dorsalis Hendel seems to decrease the quantity and quality of this fruit. On the other side, irradiation has been developed as a standard quarantine treatment to disinfest fruit fly on fruit. The objective of this research was to determine impact of irradiation by Cobalt-60 gamma-ray on the development and survivorship of eggs and the third instar of fruitfly larvae using in-vitro and in-vivo approaches and minimum dose of Cobalt-60 gamma rays applied for snake fruit. Six doses of gamma-ray, i.e. 0 (control), 25, 50, 75, 100, 125 and 150 Gy were used in this experiment. The results showed that Cobalt-60 disturbed development and survivor rate of B. dorsalis. The development of eggs into pupa was failed when treated with Cobalt-60 at any doses, while the third instar larvae failed to become adult when irradiated with 75, 100 and 150 Gy of gamma-ray. The impacts were increased with the increment of dose. Furthermore, impact of gamma-ray irradiation was greater on eggs compared to the third instar of larvae. The minimum dose of irradiation to prevent adults emerge was 118 Gy.

AbstractPlums, sweet cherry, and sour cherry trees were spaced 4.5 m × 1.5 m to be trained to “Y” and “V”-trellising systems for mechanical harvesting, with a canopy contact harvester, attending to obtain fruits meeting the requirements of the fresh fruit market. The applied trellising systems were compared with the standard central leader system at the same spacing. The most of trellised trees grew less vigorously than the standard trees, and after 3 years of training, the trees were suitable for mechanical harvesting with the harvester designed at the Research Institute of Horticulture in Skierniewice. The trellised trees were able to set as many fruitlets as those grown in the form of central leader and gave a comparable yield, but differences between cultivars were significant. Light interception in the third year after planting was lower for trees of sour cherry and plum growing in the “Y”-20° and “V” in comparison to the trees with central leader. Illumination of trellised canopies at the level of 0.7 and 1.5 m was the most favorable in “V” system when compared to control and “Y” training systems. Cost of construction for the trellising systems of stone fruits calculated per 1 ha was two times higher when compared with the standard system.

Rhageletis cerasi (L.) is the most important pest in cherry orchards and it’s attak can affect the quality of fruit on a large percentage (45-100%). The European cherry fruit fly is prezent in all cherry and sweet cherry orchards, therefore monitoring this population is required as an element of integrated protection. The aim of this study is to establish population dynamics in Cluj area. Adult flight was monitored twice a week on yellow sticky panels. Traps were placed in different parts of the orchard. The first captures were recorded in May 29, with a number of 4 adults/orchard and in 24 June we recorded the maximum number, 89 adults/orchard. By monitoring population dynamics we can determine the correct time for application of chemical treatments.

The paper presents the data collected from an ecological plot of sweet cherries with an area of 0.5 ha, where different methods of monitoring and combating the main pests were tested: European cherry fruit fly - Rhagoletis cerasi L. and black cherry aphid - Myzus cerasi F. The study took place during the years 2019-2020. European cherry fruit fly monitoring - Rhagoletis cerasi L. was performed with both atraCERAS optical panels and Decis Trap devices, with both a warning and control role, the results obtained highlighting a similar flight dynamics. The control of the European cherry fruit fly, carried out by direct control with the help of Decis Trap devices, the dose of 100 traps / ha, proved to be effective, the Abbott effectiveness indicator registering values between 83.4 - 90.5% in 2019, respectively 81.6 - 87.8% in 2020, depending on the studied variety. To control the black cherry aphid - Myzus cerasi F., the product Prev-Am was mainly used, based on orange oil, which was used with good results for the first attacks observed.

Over the period 2006–2009 in Lublin, a study was conducted to determine the effect of five types of rootstock: ‘Colt’, ‘F12/1’, sweet cherry (<em>Prunus avium </em>L.), ‘GiSelA 5’ and ‘Piast’ mahaleb cherry (<em>Prunus mahaleb </em>L.), on the growth and quality of maiden sweet cherry trees cv. ‘Regina’ in a commercial nursery. Based on the three-year average, rootstocks were shown to have a significant effect on the investigated quality characteristics of maiden sweet cherry trees. Trees budded on ‘Colt’ vegetative rootstock were characterized by strongest growth and best quality. In each year, they were thicker, higher and better branched than sweet cherries on the rootstock. Under the tested conditions, ‘GiSelA 5’ dwarf rootstock significantly reduced the growth and quality of budded sweet cherry trees in the nursery. During the period 2007–2009, no physiological incompatibility symptoms were observed ‘Regina’ sweet cherry cv. and ‘Piast’ seedling rootstocks. The growth of trees budded on ‘Piast’ mahaleb cherry was poorer than on ‘Colt’ clonal rootstock, but it was stronger than on ‘F12/1’ and <em>Prunus avium</em> L. rootstocks.

Five-year-old `Napoleon' sweet cherry (Prunus avium L.) trees were treated with single-application basal drenches of paclobutrazol (PBZ) in an attempt to regulate growth and flowering. Increasing concentrations of PBZ at 0.05 to 0.30 g·cm-1 trunk diameter reduced terminal extension the year of treatment and for at least the following 3 years. Fruit count increased on wood grown before treatment but decreased as annual growth declined following treatment. Fruit/cm growth generally increased, whereas fruit per flower bud decreased as PBZ concentration increased. No differences were found in fruit size, soluble solids concentration (SSC; 13% to 14%), or firmness of cherries harvested at brine maturity. Chemical name used: β-[(4-chlorophenyl) methyll-α- (l,l-dimethylethyl) -l-H-l,2,4-triazo1e-l-ethanol (paclobutrazol, PBZ).

The canopy of sweet cherry trees grown under cover has to be adapted to this growing system by canopy lowering, narrowing and renewing. Tree growth and productivity parameters were compared three years before and three years after canopy restriction (2006-2011) for cultivars ‘Iputj’ and ‘Krupnoplodnaya’ on rootstocks Gisela 4 and 5, Weiroot 154 and F 12/1 during the full production period. The largest trees with wider canopy both before and after canopy restriction were observed on rootstock F 12/1. Limiting pruning of trees on Weiroot 154 did not cause stronger shoot growth. On Weiroot 154 the canopy was slightly bigger than for trees on Gisela 4 and 5. Canopy volume was bigger for ‘Iputj’ before adaptation to the cover system than for ‘Krupnoplodnaya’. After canopy reduction the fruiting wood renewed slowly, and therefore, yield per tree even in the third year after pruning was almost three times less than before pruning. As cultivar ‘Krupnoplodnaya’ renewed fruiting wood faster, it was 5-37% more productive than ‘Iputj’. Productivity renewed more rapidly for trees on dwarfing rootstocks, especially on Gisela 5. The fruits of cultivar ‘Krupnoplodnaya’ were bigger both before and after pruning compared with ‘Iputj’. Of the tested rootstocks, F 12/1 was found to be not suitable for plantations under cover.

Pupae of Anastrepha suspensa (Loew) were irradiated 2 days before adult eclosión in an air atmosphere with 15, 20, 25, 30, 50 and 70 Gy of gamma radiation (Co-60). The radiation effects on sterility and other parameters of quality and behavior of males and females of caribfly were established. Males became fully sterile with a dose of 50 Gy and females laid no eggs when exposed to 25 Gy. Radiation had no significant effect on adult eclosion, sex ratio, flight ability and irritability, but female mortality was affected significantly by radiation, showing higher survival rates in low dosage treatments. The mating behavior of the males was reduced significantly by increasing the radiation doses.

Gibberellic acid-treated `Napoleon' sweet cherry (Prunus avium L.) fruit were firmer but lost more weight during brining than nontreated fruit. GA treatment delayed fruit softening, thereby extending the harvest period. Mean fruit weight was increased by GA only in fruit harvested at a more mature state. GA delayed soluble solids accumulation in one of two years. In one orchard district, solution pockets were less frequent in GA -treated fruit in 1988 and in late-harvested GA -treated fruit in 1989. GA treatment did not alter the incidence of fruit with solution pockets in a second district in 1988 and increased levels of solution pockets in fruit harvested later in 1989. Incidence of fruit with solution pockets increased as maturity progressed in nontreated fruit in both years and both districts. Chemical name used: gibberellic acid (G A).
