In this experiment, effects of pollen source of ‘Siah Mashhad’, ‘Sorati’, ‘Zodras’ and ‘Stella’ cultivars on fruit set and pollen tube growth of sweet cherry (Prunus avium L.) CV. ‘Tak Daneh Mashhad’ was studied as randomized complete block design (RCBD) in triplicate statistically. The results showed that ‘Siah Mashhad’, ‘Sorati’, ‘Pishras’ and ‘Stella’cultivars are the suitable pollinizers for ‘Tak Daneh Mashhad’ cultivar, and also ‘Tak Daneh Mashhad’ cultivar is a self- incompatible cultivar, which produced the most fruit in cross- pollination, it should be used as mixculture for orchard establishment. Results of this research showed that fruit set in pollination combinations was different. So that the highest fruit set was in ‘Tak Daneh Mashhad’ (38%) using ‘Pishras’ pollen grains, while the lowest was fruit set (22%) in this cultivar by ‘Sky’ pollen grains. Also, this investigation showed that the pollen tube growth in style with different treatments was different. But, only co...
Comparison of varying pollen source on productivity of sour cherry (Prunus cerasus L.) cultivars
International Journal of Horticultural Science, 2010
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.
Pollen performance as affected by the pistilar genotype in sweet cherry ( Prunus avium L
Protoplasma, 1999
Differences in pollen performance in higher plants can result in significant selective advantages for some particular genotypes leading to both gametophytic and sexual selection. However, the possibility of selection among male gametophytes has been questioned since natural selection could lead to the fixation of alleles for the best competing male genotypes. These two apparently conflicting hypotheses could be reconciled if pollen performance, rather than operating in absolute terms, could be modulated by the pistilar genotype. Thus, pollen performance in vivo and in vitro has been compared in four sweet cherry (Primus avium L.) cultivars. Differences among the cultivars studied have been recorded in the speed and final pollen germination percentages both in vivo and in vitro. The results obtained show that the female genotype also modulates the final result of pollen performance. These two factors are not merely additive but, on the contrary, the interaction between them affects pollen behavior in vivo. This fact has clear implications for gametophytic and sexual selection since the best male-female combinations can be favored and this could explain the variability observed for pollen performance in nature.
Investigation of pollination on compatibility of some cherry cultivars on cv. `Zard Daneshkadeh’
Sweet cherry (Prunus avium L.) is considered as one of the most important temperate zone fruits worldwide. It is an economical fruit with high demand because of its early ripening fruits that enter the market early in the season. Most sweet cherry cultivars are self-incompatible, not able to produce commercial fruit without being pollinated with a compatible pollinizer. In the present study, floweres of cv. Zarde Daneshkadea were hand pollinated using collected pollen from Sefid Rezaeieh, Napoleon, Abardeh, Bing, Shabestar cultivars as well as pollen from itself. The experiment was arranged in Randomized Complete Block Design (RCBD) with 6 treatments and 3 replicates. The pollen germination test of all the examined cultivars resulted in high germination percentages (>65%). Zarde Daneshkada, with zero percent fruit setting, was proved to be a self-incompatible cultivar. The cultivars, Shabestar, Sefid Rezaeieh and Napoleon were compatible with cv. Zarde Daneshkade, with fruit sett...
The effect of temperature on stigmatic receptivity in sweet cherry (Prunus avium L.)
Plant, Cell and Environment, 2003
Plant reproduction is highly vulnerable to environmental conditions such as temperature and, consequently, planet warming may have significant consequences on the reproductive phase with serious implication in agricultural crops. Although pollen tube growth is clearly affected by temperature, little information is available on its effect on the female side and on flower receptivity. In this work, the effect of temperature has been evaluated on stigmatic receptivity of sweet cherry in vivo , in the laboratory, and in planta , in the field. Results herein show that temperature has a clear effect on the duration of stigmatic receptivity. Thus, whereas high temperature reduced stigmatic receptivity, low temperature enlarged it. The stigma lost the capacity to offer support first for pollen penetration, second for pollen germination and, finally, for pollen adhesion. The effect of temperature was more pronounced on pollen germination and penetration than on pollen adhesion. High temperature reduced the germination capacity of the pollen as early as the first day after anthesis, a time when no apparent signs of stigma degeneration are apparent. This clear effect of temperature on stigmatic receptivity and pollen performance may have clear implication in crop performance and in establishing screening criteria of bestadapted genotypes.
Influence of Technology and Environment on the Pollen Germination Capacity in Cherry
Bulletin of University of Agricultural Sciences and Veterinary Medicine Cluj-Napoca. Horticulture, 2018
Pollen of four cherry cultivars (‘Lapins, ‘Kordia’, ‘Sylvia’, ‘Regina’) was collected and examined with microscop to determine its germination capacity. It was observed that pollen fertility varied from 18.7 % to 80.1 %. Environmental conditions of the studied area as well as applied treatments affected pollen germination capacity. Due to the high maximum temperature recorded in 13.03.2018, bud formation was induced 18 day earlier than in the previous years, growth started on March 31st, when the temperature was 21.5˚C. Regarding production, the highest yield was obtained in ‘Regina’ variety 9.7 kg/tree, ‘Kordia’ 9.3 kg/tree, ‘Lapins’ 8.8 kg/tree and Sylvia 8.2 kg/tree. In autumn of the previous year, the trees were fertilized with urea, in a concentration of 3 kg per ha, and in the spring with CROPAID, in a concentration of 5 liters per ha. The results show that germination percentage was much higher in the pollen collected from the treated trees than in the untreated ones.
Vitality and in vitro pollen germination of different ‘Oblacinska’ sour cherry clones
Genetika, 2017
Vitality of pollen, in vitro pollen germination and pollen tube growth (pollen tube length and pollen tube growth rate) were investigated in Oblacinska sour cherry in order to determine the differences between clones which have divergent yielding potential. For this purpose two ?Oblacinska? sour cherry clones with high fruit set and high yields (II/2, III/9) and two with low fruit set and low-yielding (XI/3 and XIII/1) were used in this study. Pollen germination was done on artificial medium containing 14% sucrose and 0.3% agar-agar at room temperature (23?C). Pollen tube growth was stopped with a drop of 40% formaldehyde, 1, 3, 6, 12 and 24 h after contact with the medium. The maximum percentage of germination ranged from 13.01% (clone II/2, after 1 h) to 54.19% (clone III/9, after 24 h). Pollen tube length varied from 64.84 ?m (clone XIII/1, after 1 h) to >1,100 ?m (clones II/2 and III/9, after 24 h). Pollen growth rate was quite high (up to 1.71 ?m min-1) after 6 h of germinat...
Pollen viability and longevity in some selected genotypes of peach, plum, prune and sour cherry
In stone fruit trees such as peach, plum, prune and sour cherry, pollen performance includes pollen quantity produced in a flower and pollen quality consists of viability, longevity, morphological homogeneity, pollen germination and pollen tube growth rate which are very important component of fertilization and fruit setting. However, study of main pollen traits is one of the most important approaches for the stone fruit trees growers and breeders. In this research, main pollen traits including germination, tube growth and longevity were investigated in some favorable selected genotypes of four Prunus species including peach, plum, prune and sour cherry. Pollen traits of five genotypes from each species were studied after one month maintenance in -20°C using the in vitro medium containing 15% sucrose, 1% agar and 5 ppm H3BO3 (boric acid). Pollens were planted in the in vitro medium inside the Petri-dishes and incubated at the constant temperature of 24°C for 24 h and then, pollen ge...
In vitro pollen germination and pollen grain morphology in some sweet cherry (Prunus avium L.) cultivars Abstract In vitro pollen germination on agarose-sucrose medium, and pollen grain morphology by scanning electron microscopy, were investigated in four sweet cherry (Prunus avium L.) cultivars ('Karina', 'Kordia', 'Regina' and 'Summit'). The highest percentage of in vitro pollen germination over a three-year period was observed in 'Regina' (46.60±3.58%), and the lowest in 'Kordia' (26.68±1.59%). The results suggested a major influence of cultivars specificities which induced the different response to experimental conditions among years. The differences in morphological characters of pollen grains – size and shape (length, width and length/width -L/W ratio), germinal furrows (number and shape, length, width, distance between furrows) and exine ornamentation (the number of ridges in 100 μm 2 of exine, ridges and stria width) were signi...
