Box: 2416, Cairo, Egypt Journal Article 2019 01 07 In this study fourteen microsatellite primer pairs were used to study the genetic diversity of Shishi Date palm in Qatar. A total of 32 date palm (15 Shishi cultivar, 10 Khalas and seven male date palms) were collected from Qatar and 5 Shihi cultivars were collected from Saudi Arabia ‎for comparison. The Shishi set collected from Qatar was selected from ‎different regions to represent the ‎genetic diversity of this ‎cultivar. The results indicated 98 alleles produced from the 14 microsatellite markers, and the cluster analysis showed four major clusters corresponding o the geographical areas. Similarly, the structure analysis indicated four populations according to statistic K value. PCoA analysis showed three groups (A, B and C) ‎separating Shishi (from Qatar) in group A, ‎Khalas in group B and Shishi (from Saudi Arabia) in ‎group C and no clear group ‎separated the male genotypes. This indicates that the sexual propagation by seeds is the main source of variation in the date palm. This is the first study focusing on Shishi cultivar in Qatar and Saudi Arabia by using molecular markers.

Nowadays, sweet basil, one of the best general fragrant foliage, is considered as an industrial plant. In present study to compare different levels of cow manure biochar (CMB) and humic acid (HA) on vegetative traits and mineral absorption rate of green basil plants, an experiment was conducted based on a completely randomized block design with four replications in 2015. The treatments included different levels of CMB (0, 1%, 2%, and 3%) and HA (2.5, 5 and 7.5 g/L) in the culture medium. The traits that were analyzed were included: plant height, leaf number, leaf area, stem diameter, leaf chlorophyll concentration (LCC), fresh and dry weights of aerial part and root, concentration of potassium, nitrogen, calcium and phosphorus. Results showed that fresh and dry weights of shoot and root were increased by application of 3% CMB and 7.5 g/L HA in the culture medium. Theuse of CMB and HA significantly affected most of the studied traits except LCC, stem diameter, and leaf area. Concentration of N, P, K and Ca was considerably increased by application of 3% CMB and 7.5 g/L HA in the culture medium. The highest concentration of nutrients was detected in the plants treated with 3% CMB. In conclusion, the use of 3% CMB and HA at 7.5 g/L in the culture medium can be recommended to improve the qualitative and quantitative traits of basil plants.

It could leads to significant changes in plant biochemical, physiological, and growth traits. Salinity induced endogenous rise in jasmonic acid and its methyl esters (MeJA) has been reported. In the present study, effects of salinity stress (6 and 12 ds m-1) and the exogenous application of MeJA (0.1 and 0.5 mM) on the leaf number, shoot fresh weight, shoot length, chlorophyll a/b, soluble sugar, proline, and malondialdehyde (MDA) contents were investigated in two safflower varieties (Isfahan and IL111). Salinity stress negatively affected the growth of both varieties. Lipid peroxidation was not observed in Isfahan variety, but it significantly increased in the salinity resistant safflower, IL111. Soluble sugar and proline as the important osmoprotectants and free radical scavengers were elevated by salinity stress. Exogenous application of MeJA to the salinity stress-imposed plants slightly improved the growth due to inductions in the rate of photosynthesis; however, MeJA application impaired the growth of non-stressed plants because of induction of stomatal closure and as a result reduced photosynthesis.

In the present study the effect of exogenous application of arginine (Arg) (a substrate for nitric oxide (NO) synthase) and sodium nitroproside (SNP), as a NO-donor was investigated on yield production, fruit and inflorescence buds abscission, and physiological parameters of Pistacia vera. The experiment was conducted in randomized complete block design with factorial structure in a commercial pistachio orchard. Factors were included two levels of Arg (0.5 and 1 mM), two levels of SNP (50 and 100 μM) and their combination applied at two distinct time; one week before full bloom (first stage) and five weeks after full bloom (second stage). Comparing to SNP-treated trees, Arg was more effective on growth and physiological parameters of shoots and on fruit and inflorescence buds abscission, and on fruit parameters such as split and non-split shells, blank nuts, number of nuts per ounce. Effects of these treatments were considerably depending on the time of application and the concentrations of applied compounds. It is proposed that the effects of Arg and SNP may be related to the NO signaling and polyamines production.

This investigation was carried out to detect genetic relations among 34 cultivars of Iranian date palm, both males and females, using ISSR markers. Accordingly, total DNA was extracted using CTAB method and was subjected to PCR amplification using 12 ISSR primers. Analysis of ISSR data indicated that PIC value varied from 0.3695 to 0.4998 with average of 0.4497. The highest PIC value belonged to (CT)10 G primer (0.4498). Totally, 112 alleles were recognized. According to morphological attributes and ISSR markers, the 34 studied date cultivars divided into eight main groups and different sub-groups, and no significant correlation between grouping made by morphological and molecular markers. Unlike ISSR markers that produced a clear-cut among male and female cultivars, no distinct border was seen among male and female cultivars using morphological attributes. Furthermore, PCA analysis confirmed the grouping made by ISSR markers. In conclusion, ISSR markers have been useful to separate date palm cultivars.

In modern era of agriculture, crop yield is determined on the basis of crop production per unit of water-use instead of crop production per land unit area. Deficit irrigation is introduced as a strategy for controlling water resources that leads to water resource preservation. Date palm requires regular irrigation after plantation at the primary growth stages. In the present study, the effect of applying superabsorbent polymers on required water for irrigation of date palm seedlings has been evaluated during 2011-2012. Treatments were 60%, 80% and 100% ETc irrigation and 0, 40, 80 and 120 g superabsorbents for each seedling. The experiment was conducted in RCBD and split-split plot experimental designs. Water requirement was calculated based on FAO pan method. Results showed that, percentage of establishment reduced significantly in all irrigation regimes including normal irrigation, mid stress, and severe stress. Moreover, using superabsorbents resulted in an increase in SOD activity under 80% irrigation deficit in comparison to full irrigation. Furthermore, it was demonstrated that superabsorbents significantly affected uptake of mineral nutrients and consequently resulted in a raise in seedling establishment.

The aerial parts of the grown plants in two ranges of elevation including 2000-2500 and 2500-3000 m above sea level were harvested at three time-points, including end of vegetative, flowering, and seed filling stages. The main components in the T. polium oil were α-pinene (40.52 to 54.05%), β-pinene (17.36 to 23.3%), and limonene (10.10 to 15.19%) and the major constituents in the essential oil of T. orientale were α-pinene (0.00 to 25.10%), and β-caryophyllene (18.18 to 56.01%). Analysis of results confirmed the significant effects of phenological stage and elevation on the percentages of essential oil components. High elevation above sea level caused increase in aromatic compounds such as α-pinene and limonene from monoterpene hydrocarbons but decrease in sesquiterpene compounds such as β-caryophyllene contents. There was significant correlation between essential oil constituents under different elevations and phenological stages. In addition, harvesting time at different phenological stages affected the chemical compositions in the essential oils, in a way that the highest concentrations of α-pinene and β-pinene as volatile components (monoterpene hydrocarbons) and β-caryophyllene (sesquiterpene hydrocarbons) as important constitutes in pharmaceutical industry were obtained from flowering stage.

The experiment was conducted based on a completely randomized block design with nine treatments and three replications per treatment. Treatments were three levels of K2SO4 (0, 1 and 2%) and three levels of ZnSO4 (0, 0.5 and 1%). The nutrition solutions were sprayed on trees at two times (bud swell stage and green tip stage) in 2017–2018. Based on the obtained results, nutrient treatments especially 1% K2SO4+1% ZnSO4 and 2% K2SO4+1% ZnSO4 caused a significant increase in chlorophyll a, chlorophyll b, total chlorophyll and carotenoid contents. Application of K2SO4 and ZnSO4 significantly affected concentrations of P, K, Mg, Zn, Mn and Fe in the leaves of ‘Chrokeh’ pistachio, whereas nutrient treatments had no significant effect on leaf concentration of N. Nutrient treatments especially 2% K2SO4+1% ZnSO4 led to significant increases in the fresh (up to 65%) and dry (up to 67%) yield when compared with the control trees. Moreover, nutrient applications had a significant effect on the percentage of splitting (an 11 % increase) and blankness (a 26% decrease). It can be concluded that foliar application of K and Zn fertilizers is necessary for obtaining better fruit yield and quality in pistachio.

Drought Research Center, College of Agriculture, Shiraz University, Shiraz, Iran Journal Article 2019 02 20 By applying multivariate statistical analysis, this research aimed to estimate the heritability and find relationships between the vegetative and reproductive characteristics of Prunus scoparia and Prunus elaeagnifolia. Twenty genotypes of each species were selected randomly from cultivated populations and twenty-two traits including the tree, leaf, flower, nut and kernel attributes were measured. Results showed that there were high levels of genotypic and phenotypic variations among the genotypes of both species. Many of the measurements pertaining to the leaf, flower, nut and kernel, showed very high heritability (H2 >90%) in both species, whilst some traits such as shoot diameter in P. scoparia and kernel moisture in both species had very lower heritability (H2 <50%). Generally, the heritability of measured traits in P. elaeagnifolia were higher than those of P. scoparia, especially foreconomically important traits including yield (H2 = 94 and H2 = 54.61, respectively in P. elaeagnifolia and P. scoparia), nut weight (H2 = 97.83 and H2 = 85.39.61, respectively in P. elaeagnifolia and P. scoparia) and oil percentage (H2 = 75.55 and H2 = 61.43, respectively in P. elaeagnifolia and P. scoparia). Stepwise regression analysis revealed that the most influential factors on yield of P. scoparia, were the fruit set, flower diameter and leaf length, whilst for the P. elaeagnifolia, the yield was mostly determined by fruit set and leaf area. The high genetic diversity and heritability of the studied traits, indicates high genetic potential of this germplasm to be utilized in future breeding programs.
