“…These results agree with Giordani et al (2014), which found a difference in the germination Certain olive cultivars are self-incompatible and produce little or no fruit in mono-varietal orchards. In this case, cross-pollination favours larger and more regular yields.…”

“…Pollen viability rates of olive cultivar could be variable, and the possible reasons of this situation might be related to climatic factors, cultural practices, tendency to alternate-bearing together with genetic factors as formerly exposed in different studies (Ferri et al, 2008;Palasciano et al, 2008;Mete., 2009;Gierdani et al, 2012;Mete et al, 2012;Manzzeo et al, 2014;Abacı and Asma, 2015;Karabıyık and Eti, 2015).…”

This study was aimed to determine the fertilization biology of the 'Arsel' olive cultivar obtained by hybridization breeding. For this reason, treatments of open pollination, cross pollination, and self-pollination were performed for 2 years and self-compatibility and appropriate pollinators of this new cultivar were investigated. Among the varieties included as pollinators (‘Memecik’, ‘Gemlik’, ‘Uslu’, ‘Ayvalık’ and ‘Eğriburun Nizip’), the highest fruit set was achieved with ‘Memecik’ and ‘Gemlik’ varietes in both years (2.64%, 1.37% and 1.75%, 1.39%). For this reason, ‘Memecik’ and ‘Gemlik’ cultivars were the best pollinator for ‘Arsel’ olive was thought. On the other hand, considering the statistical analyzes and productivity index values, ‘Arsel’ variety was found to be self-incompatible. However, the data also indicated that cross pollination was effective in increasing fruit set. Therefore, it is thought that the use of pollinator cultivar in orchard establishment would be beneficial in terms of yield. Pollen viability and germination tests were performed by using 2,3,5 Triphenyl Tetrazolium Chloride (TTC) and agar in petri (15% sucrose + 1% agar + 100 ppm H3BO3) methods in the study. The highest pollen viability rate was observed in ‘Memecik’ cultivar in 2020 and there isn’t statistical differences between olive cultivars in 2018. The highest pollen germination rate was observed in ‘Arsel’ cultivar in 2018. Accordingly, differences were determined between pollen viability and germination rates of examined olive cultivars in terms of years.

“…The anthers were dehydrated with silica gel and stored for 70 days in the dark, at 4 °C, inside sterile Petri dishes sealed with parafilm. Twenty-four hours before pollination, the pollen was rehydrated by placing them on discs of filter paper moistened with sterile deionized water [ 65 ].…”

Most cultivated orchids, contributing to a worldwide highly profitable industry, are originated from tropic regions. Conversely, a considerable number of spontaneous orchids, belonging to the terrestrial orchids and widely diffused throughout the European continent, are not considered for trading due to their less gorgeous appearance and for technical difficulties in seed propagation. However, a breeding programme was undertaken aimed at developing a new hybrid between Himantoglossum adriaticum H. Baumann and H. robertianum (Loisel.) P. Delforge [syn. Barlia robertiana (Loisel.) Greuter] by applying techniques of anther conservation, manual pollination and in vitro asymbiotic germination of the obtained seeds. The plantlets that originated from the protocorms after seed germination were successfully acclimatised after potting in a proper medium. The parentage of the progenies of the hybridisation experiment was assessed by sequencing the Internal Transcribed Spacer assembly (ITS) and plastid barcoding markers of the parental lines and of the hybrids. The method proved to be effective in revealing the origin of the hybrids and to validate the maternal inheritance of the plastid DNA.
