“…The flowering period of the studied cultivars ranged between 15 and 20 days in 2014 and between 14-18 days in 2015. This was in agreement with Abo-El-Ez and Hassenein (2009), Eassa et al (2011), Selak et al (2011) Mehri et al (2013) and Fayek et al (2014) who reported that olive blooming lasts for about 2 -3 weeks.…”

“…Results achieved in the current study relative to self-pollination and to increase in fruit set under open pollination confirmed the reports on other olive cultivars (Selak et al, 2011;Spinardi and Bassi, 2012;Mehri et al, 2013;Taslimpour and Aslmoshtaghi, 2013;Fayek et al, 2014 andMete et al, 2016).…”

“…attained significantly the least percentages in both seasons of study. These results are in line with Wu et al (2002) Al-Kasasbeh et al (2005, Eassa et al (2011), Seifi et al (2011); Sayed (2013) and Mehri et al (2013) who reported that the relative proportion of perfect flowers varied according to varieties and seasons. Sex ratio also varied according to genetic factors (Fayek et al, 2014), climate and alternate bearing (Al-Shdiefat and Qrunfleh, 2008).…”

The present study was carried out during two successive growing seasons 2014 and 2015 in a private orchard located at Cairo-Alexandria desert road, 64 km from Cairo, to evaluate the efficiency of pollinator on productivity and quality attributes of eight olive cultivars, namely Aggizi, Dolce, Kalamata, Maraki, Coratina, koroneiki, Picual and Manzanillo. Ten year old olive trees, grown in sandy soil, planted at 6 X 3 meters apart and irrigated by the drip irrigation system were used for this investigation. The results revealed that, there were differences in the onset and duration of flowering among the studied cultivars in both seasons. The earliest cultivar in flowering was Aggizi, while the latest cultivar in this respect was Kalamata Cv. in both seasons. Regarding flowering duration, it was observed that the studied cultivars overlapped in their blooming period where it is varied between 15 and 20 days in 2014 and 14-18 days in 2015. The highest perfect flower percentage was observed in Dolce and Coratina Cvs. With respect to self-incompatibility index, Aggizi, Dolce, Maraki and Koroneiki were self-compatible. Then, Picual and Coratina Cvs. recorded partially self-incompatible, whereas, Kalamata and Manzanillo Cvs. recorded higher degree of selfincompatibility,Cross pollination induced the best results with regard to fruit set %, and fruit weight and oil content in most olive cultivars. It can be recommended that, the suitable pollinator for each cultivar were as follows: Maraki and Aggizi were good pollinators for each other, Koroneiki for Dolce, Manzanillo and Picual. Finally, Dolce was a good pollinator for Kalamata, Coratina and Koroneiki.

“…The obtained results of the abovementioned flowering aspects positively affected by seven olive studied cultivars are in general agreement with that found by (Griggs et al, 1975) who stated that the relative proportion of perfect and staminate flowers varies with varieties and with the particular year. Moreover, (Fabbri, et al, 2004;Mehri, et al, 2013 andAhmed et al, 2019) found that the percentage of perfect flowers in olive widely vary as a result of regional condition or year, cultivars, tree nutrition status as soon as shoots and inflorescence. Lavee et al (1996) reported that flower bud induction and differentiation in olive trees depends on some factors as, environmental, nutrition and hormonal balance in the trees.…”

The current study was conducted during two successive seasons (2019 and 2020) on seven fruitful olive cultivars (Olea europaea L.). The environmental adaptability of species and varieties has a significant impact on sustainable agricultural development and adaptation to climate change in arid and semi-arid regions. The vegetative growth, flowering, yield, fruit characteristics, and oil contents as well as salinity stress tolerance of seven olive cultivars ("Aggizi Shami", "Dolce", "Picual", "Manzanillo", "Coratina", "Koroneiki" and "Arbequina") in saline calcareous soils were studied. The results showed that "Coratina" and "Koroneiki" produced the longest highest canopy volume in comparison with the other studied cultivars, while "Arbequina" had the smallest ones followed by "Dolce" cultivar. Sexual expression as a percentage of ideal flowers differed significantly among the cultivars studied and the seasons. The highest yield was recorded in "Aggizi Shami" at 23.44 and 43.08 in 2019 and 2020 respectively. In contrast, the "Arbequina" variety recorded the lowest yield weight (kg/tree) in both seasons. The "Koroneiki" and "Coratina" varieties recorded the highest percentage of oil, while "Aggizi Shami" and "Dolce" recorded the lowest percentage. Moreover "Picual" and "Arbequina" cultivars had the highest leaf proline contents while "Dolce" cultivar had the least ones. From these results it can conclude that "Coratina" "Koroneiki", "Picual" and "Aggizi Shami" are the most suitable olive varieties under the studied conditions. These four cultivars have appropriate salinity responses and are recommended for cultivation in salinity affected areas.
