“…It is usually harvested and consumed at Ruttab stage when fruits reach the end of full maturity during the loss of yellow color .There is a real problem in the pollination of this cultivar . The female flowers" acceptability differs between varieties, this is due to the sexual incompatibility or other genetical reasons which prevent the flower"s fertilization and fruit"s set [2] , [3] .In other study Fattahi et al [4] assured that pollination of fruitful trees is a vital step for having a good product. Also many researches proved that the fruit set percentage differ between cultivars and that pollen grains effect directly the female flowers.…”

This research was conducted in orchard belong to Al-Mahawel date palm station (Abo Sderah) / Ministry of Agriculture located in governorate of Babylon, during the season 2015-2016. Twenty four uniform date palm Phoenix dactylifera. L. Sultani cultivar were used , to study the effect of the pollinator type(P1: Ghannamiakhder , P2: Ghannamiahmer and P3:khukri ), the concentration of Naphthalene Acetic Acid NAA(0 , 50 and 100 ) mg.L-1 and their interaction on fruits setting up , fruits drop and some of physical and chemical characteristics of fruits of date palm Sultani cultivar .Experiment carried out as factorial experiment(3×3) by Randomized Complete Block Design (RCBD) with three replications in each treatment , and the means were compared using LSD level of significant test at P ≤ 0·05. The results can be summarized as that Ghannamiahmer (P2)cultivar and 50 mg.L-1 NAA application showed a significant increase in the fruit setting% , while Khukri cultivar(P3) showed significantly increased fruit size and weight as compared with the other cultivars.Furthermore the cultivar(P1) obtained a significant increase in the bunch weight in Rutab stage as compared with the other cultivars. While the cultivar (P2) with 100 mg.L-1 NAA application showed significant increase in bunch weight in Rutab stage as compared with the other interactions. Ghannamiakhder (P1) cultivar had a significant increase in the fruit content of reducing sugars and non-reducing sugars, while khukri showed significant increase in fruit content of dry matter% and total sugars as compared with the other cultivars.

“…For example, self-pollinated kernels of some almond cultivars have lower oleic:linoleic acid ratios than cross-pollinated kernels [25,29]. In addition, self-pollinated kernels of some almond, chestnut and hazelnut cultivars are smaller than cross-pollinated kernels [22,[31][32][33]. Such effects of the paternal genetic background on the size or quality of the embryo are termed "xenia", and xenic effects are common in fruit and nut crops [34].…”

Tree nuts play an important role in healthy diets, but their economic value and nutritional quality may be affected by their size and paternity. We assessed relationships between nut size and kernel recovery, the incidence of whole kernels, fatty acid composition and mineral nutrient concentrations in three macadamia cultivars, "Daddow", "816" and "A4". We determined to what extent differences in nut size and quality were the result of different levels of cross-or self-paternity. Small nuts of all cultivars had lower kernel recovery than large nuts, and small nuts provided lower incidence of whole kernels in "Daddow" and "A4". Small kernels had a lower relative abundance of the saturated fatty acid, palmitic acid, in all cultivars and higher relative abundance of the unsaturated fatty acid, oleic acid, in "Daddow" and "A4". Small kernels had higher concentrations of many essential nutrients such as nitrogen and calcium, although potassium concentrations were lower in small kernels. Most nuts arose from cross-pollination. Therefore, nut size and kernel quality were not related to different levels of cross-and self-paternity. Identified cross-paternity was 88%, 78% and 90%, and identified self-paternity was 3%, 2% and 0%, for "Daddow", "816" and "A4", respectively. Small macadamia kernels are at least as nutritious as large macadamia kernels. High levels of cross-paternity confirmed that many macadamia cultivars are predominantly outcrossing. Macadamia growers may need to closely inter-plant cultivars and manage beehives to maximise cross-pollination.Plants 2020, 9, 228 2 of 14 also a valuable source of calcium, iron and zinc, which can be absorbed insufficiently during phases of high dietary demand such as infancy, childhood, adolescence, pregnancy and breastfeeding [16][17][18][19][20][21].The fatty acid composition and nutrient concentrations of tree-nut kernels can vary greatly among cultivars [9,[22][23][24][25][26][27][28]. Fatty acid composition and nutrient concentrations can also vary within almond or pistachio cultivars because of differences in the pollen parentage of individual kernels [22][23][24][25]29,30]. For example, self-pollinated kernels of some almond cultivars have lower oleic:linoleic acid ratios than cross-pollinated kernels [25,29]. In addition, self-pollinated kernels of some almond, chestnut and hazelnut cultivars are smaller than cross-pollinated kernels [22,[31][32][33]. Such effects of the paternal genetic background on the size or quality of the embryo are termed "xenia", and xenic effects are common in fruit and nut crops [34]. Therefore, maximising both yield and human-health benefits may depend upon ensuring high levels of cross-pollination in tree-nut orchards.Relationships between kernel size, nutritional composition, and cross-or self-paternity are poorly understood for some nuts, including the subtropical tree nut, macadamia (Macadamia integrifolia, M. tetraphylla and hybrids). Macadamia flowers are bee-pollinated and partially self-incompatible [35][36][37][38][39][40][41][42]...

“…However, the dry pulp oil contents of lines 5-20 and 5-6, which were hybrids between 'Yousheng' and MK88-01, were only 10.98 and 7.39%, respectively. Pollen xenia, which is defined as the effect of pollen sources on fruit quality and quantity, has been reported in pistachio (Cran and Iwakiri, 1980), hazelnut (Weingartner et al, 2004) and maize (Fattahi et al, 2014). For example, the use of pollen from small-seeded pistachio cultivars was shown to generate small seeds in cultivars that typically produce large seeds (Cran and Iwakiri, 1980).…”
