“…Indeed, after 24 h the trend continued for pollen originated from clones II/2 and III/9 (48.76% and 54.19%, respectively). The range for percentage of pollen germination reported in this work was in agreement with the findings of TOSUN and KOYUNCU (2007) and SZPADZIK et al (2008). Differences in pollen germination might be due to differences in the nutritive status of the developing pollen grains, affected by environmental conditions (extremely high and/or excessive cold) and even inbreeding in the a * a b b…”

“…Studying and understanding the reproductive phases are crucial for agricultural practice. As in other fruit trees, pollination, stigma receptivity, pollen germination, pollen tube growth, effective pollination period and ovule fertilization are all important factors affecting both fruit set and fruit yield in sour cherry (Prunus cerasus L.) (SZPADZIK et al, 2008;FOTIRIĆ AKŠIĆ et al, 2013). Consequently, these aspects of reproductive biology are critical for optimizing yields in sour cherries and make them important criteria for breeding programmes (SHARAFI, 2011).…”

Vitality of pollen, in vitro pollen germination and pollen tube growth (pollen tube length and pollen tube growth rate) were investigated in Oblačinska sour cherry in order to determine the differences between clones which have divergent yielding potential. For this purpose two 'Oblačinska' 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 μm (clone XIII/1, after 1 h) to >1,100 μm (clones II/2 and III/9, after 24 h). Pollen growth rate was quite high (up to 1.71 μm min-1) after 6 h of germination, but rather decreasing until 24 h of germination (0.560.83 μm min-1). The dynamics of in vitro pollen tubes growth among the clones were quite different, especially after 12 h and 24 h of germination. Clones that are singled out as fruitful (II/2 and III/9) gave much better results regarding pollen germination and pollen tube growth in comparison to clones which were characterized by low fruit set and yields (XI/3 and XIII/1).

The aim of the study was to estimate the effect of' tree pruning intensity on the yielding and quality of fruits of the sour cherry (Prunus cerasus L.) cultivar 'Łutówka'. An experiment with a different intensity of tree pruning was carried out in the years [2006][2007][2008][2009][2010] . In the plantation, three pruning regimes were applied: 1) no pruning (only sanitation felling was applied), 2) moderate traditional pruning (consisting of the shortening of branches), 3) intensive pruning (by removing branches older than three years). Tree yielding significantly depended on the weather conditions of the experimental years. With increasing pruning intensity the yield decreased. Tree pruning and its intensity influenced fruit quality measured by the weight of 100 fruits, fruit firmness, acidity and total soluble solids. Colour variation of 'Łutówka' skin was assigned the following parameters L*, a*, b*, C* and h°. Their changes varied depending on the year and orchard.

Sour cherry (Prunus cerasus L.) is one of the most important fruit crops in Poland. There are many varieties cultivated in orchards, but only a few of them play an important role in commercial production. These few varieties have been the object of numerous studies focused on practical aspects like growth performance, yielding, or resistance to diseases. Recently more belowground research has been carried out in pomological plants using the minirhizotron research allowing to observe roots in short and long term experiments. There have been very few studies concerning root growth dynamics of sour cherry cultivars. Here we studied the influence of four major factors on root growth: the cultivar, root diameter, soil depth, and season on the survivorship of fine roots. We used the minirhizotron technique (MR) to examine fine roots dynamics of four sour cherry cultivars grafted on the Mahaleb rootstock, grown in an experimental orchard in Central Poland. The results revealed that the greatest impact on root survivorship was exerted by root diameter, depth of root formation and the season, whereas cultivars had no obvious influence. The finest roots (with a diameter <0.2 mm) and roots formed at a depth of down to 10 cm below the soil surface had the shortest survivorship. On the other hand, thicker roots (>0.75mm) and roots formed at a depth of more than 50 cm below the soil surface have the longest survivorship. The season of root growth has little impact on root survivorship, but has a big influence on the number of the roots formed. There is no impact of the cultivar on the differences in observed roots survivorship.
