AbstractThe fruit of date palm trees are an important part of the diet for a large portion of the Middle East and North Africa. The fruit is consumed both fresh and dry and can be stored dry for extended periods of time. Date fruits vary significantly across hundreds of cultivars identified in the main regions of cultivation. Most dried date fruit are low in sucrose but high in glucose and fructose. However, high sucrose content is a distinctive feature of some date fruit and affects flavor as well as texture and water retention. To identify the genes controlling high sucrose content we analyzed date fruit metabolomics for association with genotype data from 121 date fruits. We found significant association of dried date sucrose content and a genomic region that contains 3 tandem copies of the beta-fructofuranosidase (invertase) gene in the reference Khalas genome, a low sucrose fruit. High sucrose cultivars including the popular Deglet Noor had a homozygous deletion of two of the 3 copies of the invertase gene. We show the deletion allele is derived when compared to the ancestral allele that retains the all copies of the gene in 3 other species of Phoenix. The fact that 2 of the 3 tandem invertase copies are associated with dry fruit sucrose content will assist in better understanding the distinct roles of multiple date palm invertases in plant physiology. Identification of the recessive alleles associated with end-point sucrose content in date fruit may be used in selective breeding in the future.

Sorghum Chafer

Four insect species were reported as new potential pests of date palm in recent years. They are sorghum chafer (Pachnoda interrupta), the rose chafer (Potosia opaca), the sericine chafer beetle (Maladera insanablis), and the South American palm borer (Pysandisia archon). The first three species belong to the order Coleoptera and the family Scarabaeidae, while the fourth species is a lepidopteran of the family Castniidae. The injury as well as the economic damage caused by the four species on date palm need to be quantified. Due to climate change and anthropogenic activities, the date palm pest complex is expected to change in the future. To the author's knowledge, this article provides the first report of sorghum chafer as a pest damaging date palm fruit.

Date palm is unisexual, being either male or female. Male and female flowers grow on buds called Spathe, which opens naturally when fully mature. It is easy to identify the male and female flowers. Under the method of manual pollination, pollen from a male flower is smeared over female flowers. The pollen variety and pollination time have important effects on date palm fruit set, yield and quality. This experiment was carried out to study the effect of date pollinizer variety and pollination time on fruit set, growth and development of Medjhol date palm variety, in date palm garden of date palm and tropical fruit research institute of Iran during three years from 2009 to 2011. The trail was randomized complete block design in factorial manner with three pollen variety as Ghaname, Vardy, and Samesmave, two pollination time as 1-3 days before or after spathe opening and four replication. The results showed that the Vardy pollen had significant effects and increased the fertility percent and fruit yield, rather than two other pollen varieties. The pollen variety had no significant effects on fruit quality as total sugar, acidity, and bricx. The pollination time before spathe opening significantly increased fertility percent, decreased fruit weight and date palm yield. Finally the pollen variety and pollination time interaction effects showed that, application of Vardy pollen from 1-3 days after spathe opening with the most production date palm yield, equal 19.9 kilogram per any date palm trees, so this treatment is the best and are recommended.

Effect Of Feeding

Background : Female menstrual changes in hormone concentration influence appetite and eating behavior. As well, eating pattern has some influences on menstrual hormonal status. Feeding date palm fruit has been found in our previous report to affect menstrual hormones and some menstrual parameters. Objective: The aim of this research is to study the effect of feeding dates on energy, macronutrient, and fiber intakes, body weight, and body fat%. Additionally, this study aims to find any correlation between menstrual hormone concentration and the above-mentioned parameters. Methods: A convenient sample (n=37) of not-sexually active females aged 20-30 were divided into two groups; one group (dates group) was fed 7 dates and the other served as a control group. The participants of the control group were exposed to the same experimental conditions except for eating dates. Throughout the feeding trial, the volunteers filled a 3-day food record; one menses day and two non-menses days. Results: There was a significant effect of the menstrual status-feeding duration interaction in terms of protein and fat intakes. Additionally, menstrual status, as well as feeding duration, affected energy and macronutrient intakes significantly. Furthermore, feeding duration affected fiber intake significantly. Despite the above-mentioned differences in energy and macronutrient intakes, these effects didn’t affect the body weight and body mass index of the study participants, neither their body fat%. Moreover, we have found significant correlations between nutrient intakes and menstrual hormone concentration. Conclusion : Feeding dates affected energy, macronutrient, and fiber intakes significantly. These effects were related to the changes in menstrual hormone concentration.

Background: Breastfeeding is exceptionally superior, giving mother and infants distinct and subtastial physical, mental, and developmental health advantages. Palm fruit has content of phytonutrients with antioxidant properties and galactagogues to help increase their milk supply in the early postpatum days. The lowest exclusive brest feeding rates in DIY is in the city of Yogyakarta. Exclusive breast feeding improves infant immunity so as to minimize the occurrence of diarrhea, constipation, fever that is caused by some allergic reactions. Objectifive: :This study aimed to analyze the relationship between date palm fruits on postpartum to prolactin and volume of breast milk Method: Research was conducted on maternal postpartum which is divided into two groups. They are the control group; and the treatment group which was given dates palm fruit. Breast milk volume and prolactin was measured at 3 day after labor. The analytical method used is Student T-test. Results: Date Palm fruits increased prolactin and volume of breast milk which was significantly on firstweek breastfeeding increase in the treatment group compared to the control group at p <0.05. Conclusion: Date Palm fruits is one of the alternatives that can be done to improve the success of exclusive breast feeding on postpartum. Key Words: Date palm fruit, postpartum, prolactin and volume of breast milk

Objective: Doxorubicin (Dox), an anthracycline antibiotic, has been widely used to treat cancer, principally hematological malignancies, and solid tumors. The administration of Dox is a topic of concern in the medical community, as it frequently related to dose-dependent cardiotoxicity. Therefore, the present study was designed to investigate the protective potential of date palm fruit extract on Dox-induced cardiotoxicity.Methods: A total of 40 female albino rats were used in this study and classified into four groups including control, date palm fruit extract, Dox, and treated date palm fruit extract groups.Results: Dox produced a significant increase in creatine kinase-MB and lactate dehydrogenase activities. It also decreased the activities of cardiac glutathione peroxidase and superoxide dismutase but increase levels of cardiac malondialdehyde and also of urinary 8-hydroxy-2-deoxyguanosine. Myocardial toxicity of Dox also appeared in the elevation of serum total cholesterol, triglycerides, and low-density lipoprotein cholesterol levels, while level of high-density lipoprotein cholesterol decreased. Histopathological studies revealed alteration of cardiac tissue structure by Dox. Treatment with date palm fruit extract restored the aforementioned parameters.Conclusion: Date palm fruit exhibits a cardioprotective influence on the heart tissue against toxicity induced by Dox.
