Fruit Set of Several Sour Cherry Cultivars in Latvia Influenced by Weather Conditions Before and During Flowering

The effect of genotype and temperature interaction on pollen performance in the pistils of autochthonous sour cherry cultivar ‘Feketićka’

“…Although 'Čačanski Rubin' generally behaved like a poor polliniser, in some parameters of pollen tube kinetics it was better in colder flowering conditions. Similar results were reported for sour cherry 'Latvijas Zemais', which showed better results as polliniser in the years with lower temperatures (Feldmane et al, 2017). Sweet cherries behaved similarly, whereby 'Newstar' showed better performance in terms of pollen tube number than all the pollinisers.…”

“…An increase of temperature above 10°C (three days after pollination and later) accelerated the pollen tube growth and shortened the time required to reach the base of the style and at the same time did not negatively affect the fruit set(Radunić et al, 2017). In the study ofFeldmane et al (2017), a negative effect of increasing average daily air temperature during flowering on fruit set was pronounced for several sour cherry cultivars. Therefore, the fruit set in this experiment was…”

Effect of the application of plant hormones on the formation of parthenocarpic fruits and oil production in oil palm interspecific hybrids (<i>Elaeis oleifera Cortes</i> x <i>Elaeis guineensis</i> Jacq.)

“…When the flower reaches anthesis under assisted pollination conditions, it can follow two paths: senescence and abortion of the flower, or fruit set and fruit development. The route followed depends on pollination success, pollen grain germination, and fertilization (Feldmane et al, 2017;Jahed & Hirst, 2017). Hormonal signals mediate this process.…”
