“…The duration of the EPP in fruits varies and can be from one day, as found in pear cultivar 'Doyenné du Comice' [15] up to 12 days in peach cultivar 'Earlihale' [32] and some olive cultivars [33]. EPP has been studied in many temperate and subtropical fruit species, such as apple [30,34], pear [35], japanese quince [36], peach [37], apricot [38], sweet cherry [39], sour cherry [21], almond [40], olive [41], red currant [42], rabbiteye blueberry [43], kiwi [13,44], mango [45], avocado [46], and some citruses [47].…”

This study evaluated the effective pollination period (EPP) in four European plum (Prunus domestica L.) cultivars (‘Mallard’, ‘Edda’, ‘Jubileum’, and ‘Reeves’) during two years (2018–2019) under the environmental conditions in western Norway. The pollination of plum cultivars was carried out one, three, five, seven, and nine days after anthesis (DAA) with a pollen mix of two compatible cultivars (‘Victoria’ and ‘Opal’). Initial, middle-season, and final fruit set was recorded after one month and two months after pollination and just before the harvest, respectively. On average from both years cultivar ‘Jubileum’ had the highest fruit set when pollinated one, three, five, seven, and nine DAA (33.23%, 30.83%, 8.47%, 3.08%, and 1.15%, respectively), which was more than two folds higher fruit set than in the other studied cultivars. Cultivar ‘Jubileum’ showed significantly reduced fruit set between pollination on five and nine DAA, while cultivars ‘Mallard’, ‘Edda’, and ‘Reeves’ had markedly reduced fruit set if pollinated three to five DAA, implying that the EPP in ‘Jubileum’ was five days while in the rest it was three days. Variation of weather conditions during the flowering period in both years did not have a major effect on the receptivity of stigmas in the studied plum cultivars, which means that the existing differences in the length of EPP is maternal-genotype dependent.

“…Consequently, the reduced number of seeds in fruit may result in decreased fruit weight. A short effective pollination period is unfavorable, especially during low temperatures and the low activity of pollinators [20]. Reduction of the effectiveness of pollination and ovule fertilization in unfavorable environmental conditions has been observed by many authors [16,21].…”

Optimal weather conditions are necessary for the proper course of the flowering process and high activity of pollinators, which is the most important factor affecting pollination. Because weather conditions do not always favour effective pollination and because pollinators’ activities are decreasing, the application of compound stimulating pollination and fertilization may be a good perspective for increasing yield. Titanium is considered a beneficial element for plants. Preliminary studies have indicated the positive effect of titanium organic complex on pollen adhesion to the stigma and pollen germination on the stigma of tomato and cucumber. Therefore, a 2-year experiment was designed to determine the effect of titanium organic complex application on the pollination process and fruit development of apple cv. Topaz (Malus domestica Borkh.) The experiment demonstrated the positive effect of titanium organic complex on fertilization of ovules because of effective pollination, seed setting, and fruit development of apple. Application of titanium organic complex improved pollen adhesion to the stigma and pollen germination on the stigma. In addition, titanium organic complex increased the number of pollen tubes growing through the pistil style, which resulted in fertilization that was more effective, as confirmed by the higher number of seeds set in fruits. Higher numbers of seeds set in fruits positively affected their weight and size. Therefore, fruit harvested from trees to which titanium organic complex was applied were characterized by greater weight, length, and diameter compared to fruits obtained from the trees to which titanium organic complex was not applied.

Angiosperms have evolved the unique processes of double fertilization and fruit development as key steps of their survival and dispersal strategies. In this chapter, we will examine fertilization and fruit initiation as central restriction points to fruit and seed development. Pollination and fertilization appear essential for fruit initiation, since angiosperm flowers universally enter terminal senescence and abscission phases if pollination is prevented. We review key developmental processes, pathways and genes that were recruited to control and restrict the reproductive growth of the carpel and ovule until fertilization is achieved. Ever since the discovery that exogenous application of phytohormones results in the development of seedless fruit without fertilization (termed parthenocarpy), most research has concentrated on the role of endogenous phytohormones as triggers for fruit initiation after fertilization. We will highlight how uncoupling of fruit initiation from fertilization through mutational studies can further contribute to the understanding of these complex processes. Initial analysis shows that strict local control of auxin signalling, through a transcription factor network, forms one of the decisive and primary events that leads to the hierarchical control over gibberellin metabolism and perception. Testing and challenging these assumptions will provide further knowledge indispensable for controlling fruit set and yield in agriculture.
