Effect of Different Pollinizer Sources on Yield, Fruit Characteristics and Phylogenetic Relationships with Amhat Cv. Date Palm (Phoenix dactylifera L.) in Egypt Using RAPD Markers

Influence of pollen source and its mineral content on fruit retention and quality of Kadary date palm cultivar (Phoenix dactylifera L.)

“…Also, it caused no major positive between the different pollination treatments, which drive to the pollen grain available equally matched in its effectiveness on the pollination and fertilization process. These results are in line with those of Mostafa et al [33] , who found that fruit length was not positive by different male pollen grain in the second season. Shafique et al [29] reported that non-reducing sugar, total sugar, and moisture content percentage in first season, and total soluble solid, total acidity, reducing sugar, and moisture content percentage in the second season were not positive by different male pollen grain.…”

“…The results indicated that fruit length in the first season, seed weight in both seasons, and nonreducing sugar and total sugar percentage in the second season were positive by different pollen grains. Similar results were reported by El-Kosary [34] , El-Salhy et al [35] , Soliman [22] , Aly [30] , Osman and Soliman [36] , El-Kosary and Soliman [37] , Al-Hamoudi et al [31] , Iqbal et al [38] and Mostafa et al [33] . The pollen grain treatment affects the sugar content of the fruit by the activity of the enzymes initiated by the metaxenia effect.…”

“…These results are in accordance with those obtained by Omar et al [32] . In addition, Mostafa et al [33] reported negative in pollen grain treatments in the first season. several causes such as pollination process by all males studied on the same palm, weather and weather conditions, germination, and pollen tube growth within the natural inflorescence in all treatments.…”

Productivity, Fruit Properties, Histological Relationship and Molecular Markers of Four Egyptian Female Date Palm Cultivars and Five Different Pollinizers

“…Concerning Zaghloul cultivar, the obtained results showed that Rasheed was the superior for recording the highest sugars content in the fruits also in the two studied seasons. The obtained results concerning the effect of different pollen grain sources on bunch weight, fruit size, fruit length, fruit diameter, fruit shape index and total sugars are in agreement with those recorded by Mustafa et al (2014), Merwad et al (2015), Samy et al (2015) and Mostafa et al (2016), since they found that the differences between pollinizer source had a great effect on bunch weight and both weight, size, length, diameter and shape index of date palm fruits, also the total sugars content in the fruits.…”

Date Palm Pollen: Features, Production, Extraction and Pollination Methods

“…Due to the influence of DPP source on fruit characteristics, farmers select the pollen sources that positively influence the yield and the physical-chemical quality of the fruit. Various studies have been carried out seeking to identify the best male pollinators [20,[32][33][34][35]. Studies have recently been carried out in Mexico, where the effect of pollen on nutritional properties of the fruit and seed has been analyzed in the "Medjool" cultivar [4,25,26].…”
