Citrus and palm trees’ extracts, commercially formulated as ProAlexin PNSTM and AgrisprayTM, were studied against the pistachio psyllid, Agonoscena pistaciae, in field conditions. Generally, foliage spraying application against the pistachio psyllid may cause severe reduction on the honeybee forager population, which visits infested trees to collect honeydew. ProAlexinTM products have the same formulation with Provigoro 14 WA Bee Care?, a natural water acidifier, which not only has negative action on the honeybees, but also shows disinfectant action against Nosema spp. The scope of the present study was to determine any effect of ProAlexin products on the reduction of the population of the pistachio psyllid, Agonoscena pistaciae. Experiments were performed at the orchard of the A.U.A., with two mixtures sprayed on psyllid infested pistachio trees, the first with ProAlexin PNSTM and AgrisprayTM and the second only with AgrisprayTM. They were both applied with the addition of APG25TM non-ionic surfactant. Results showed that mortality on the trees treated with ProAlexin PNSTM + AgrisprayTM mixture and AgrisprayTM was significantly higher compared with the control. This could be explained due to the phytoalexins that these products elicit, which are part of the plant mechanism against insect herbivores. These products are potentially promising methods to be used in sustainable agriculture approaches against the pistachio psyllid and they should be tested for their effects on the biological control agents of this pest. Beyond this, the results of this study encourage to test their effects on other pests of pistachio and other tree species. 展开更多

Although cultivation and utilization of Pistacia are fully exploited, the evolutionary history of the Pistacia genus and the relationships among the species and accessions is still not well understood. The aim of this study was to analyze random amplified polymorphic DNA(RAPD) in a total of 50 accessions of wild pistachio species, which included five populations Pistacia vera, Pistacia khinjuk,Pistacia atlantica, Pistacia mutica, and Pistacia eurycarpa.High levels of genetic diversity were detected within wild pistachio accessions, as revealed by using the unweighted pair-group method with arithmetic averaging and supported via analysis of molecular variance. The objectives of this investigation were to estimate marker indices, polymorphic information contents(PICs), and genetic similarities(GS)for RAPD markers; assess the genetic diversity of Pistacia species, using GS estimated from RAPD fingerprints and molecular characterization; and facilitate the use of markers in inter-specific introgression and cultivar improvement.Out of the 149 polymerase chain reaction fragments that were scored, 146(97.98 %) were polymorphic. Genetic similarities ranged from 0.3 to 0.86 %, marker indices ranged from 2.98 to 17.74 %, and PICs ranged from 0.80 to0.99 %. Our results provided great molecular identification of all assayed genotypes, which have shown that there is large quantity of genetic diversity among the pistachio accessions. This finding might render striking information in breeding management strategies for genetic conservation and cultivar development. 展开更多

We assessed different rootstocks and grafting techniques to clonally propagate mastic tree (Pistacia lentiscus var. chia). Mastic tree is a dioecious tree but the quantity and quality of the resin secreted by female trees are very low; therefore, male trees that are clonally propagated are used to establish commercial plantations for mastic production. Conventional long branch cuttings for clonal production requires too much materials and has a very low rooting rate. Rooting with tissue culture and green cuttings has also failed outdoors. Grafting of mastic on other Pistacia species has not been tried so far; therefore, this study was aimed at developing grafting methods for the clonal propagation of mastic. P. atlantica and P. lentiscus rootstocks were grafted from 15 February to 15 October every 15 days using three grafting methods and a two-factor randomized block trial design. Early spring (15 February-15 March) proved to be the best time for grafting using either of the rootstocks. The highest grafting success was attained using the scions grafted on P. atlantica from 15 February to 15 March. The best bud-burst percentage was obtained using P. atlantica and P. lentiscus rootstocks. 展开更多

It can adapt to unfavorable environmental conditions. To find the suitable ecological conditions for pistachio species, we investigated different environmental factors such as gradient, aspect and position of the slopes through the distribution area. Frequency of pistachio trees in the north and northwest of Qalajeh forests was 36.4% and 1%, respectively. Maximum (32%) and minimum (13%) number of wild pistachio trees were in 30%--60% and 〉120% slope classes, respectively. The most number and least number of pistachio trees were found at elevations of 1100-1200 m and 2200-2300 m, respectively. The percentage of pistachio canopy coverage was 10. The average percentage of herbaceous coverage was 6.5. Pistachio trees of diameter per hectare at breast height (DBH) 〉20 cm numbered 5 while average number of pistachio trees was 8 per hectare. Pistachio seedlings per hectare averaged 3.5. The number of other species per ha was 7 trees. The effect of aspect on other species was not significant (p=0.151). Slope class and geographical aspect did not affect regeneration (p=0.275 and p=0.111, respectively). Pistachio plays an important economic role in semi-arid areas, therefore it is essential to protect and restore Qalajeh forests through participation by government and local people. 展开更多

Pistacia is an economically important genus because it contains the pistachio crop, P. vera, which has edible seeds of considerable commercial importance whose value has increased over the last two decades reaching an annual value of about $2 billion (harvested crop). The taxonomic relationships among its species are controversial and not well under- stood due to the fact that they have no genetic barriers. The taxonomy of this genus is revised in detail through our re- search. It includes the following taxa: Pistacia atlantica Desf., P. chinensis Bunge subsp. chinensis, P. chinensis subsp. falcata (Bess. ex Martinelli) Rech. f., P. chinensis subsp. integerrima (J.L. Stew. ex Brandis) Rech. f., P. eurycarpa Yalt., P. khinjuk Stocks, P. lentiscus L. subsp. lentiscus, P. lentiscus subsp. emarginata (Engl.) AL-Saghir, P. mexicana Humb., Bonpl., & Kunth, P. X saportae Burnat, P. terebinthus L., P. vera L., and P. weinmannifolia Poiss. ex Franch. The genus is divided into two sections: section Pistacia and section Lentiscella. A key to the 14 taxa that have been recognized by this study is included. The new combination P. lentiscus subsp. emarginata (Engl.) AL-Saghir is made, and the names P. chinensis subsp. integerrima (J. L. Stew. ex Brandis) Rech. F., P. terebinthus L., and P. vera L. are lectotypified. 展开更多

Only a few species of aphids induce galls. Among these, Paracletus cimiciformis, Forda marginata, Forda formicaria, Geoica utricularia and Baizongia pistaciae induce galls on Pistacia terebinthus leaflets. Prior to present study the author examined microscopically P. terebinthus leaflets. He also studied the microscopic morphology of galls induced by the five species mentioned above. A clear microscopic difference between these galls is that in the wall of galls induced by the genera Paracletus and Forda a single vascular bundle is seen. The interpretation is that these galls are laminae of the modified leaflets. However, in the walls of the galls induced by the genera Geoica and Baizongia, two vascular bundles are observed. In the present paper a study of the early stages of development of galls produced by G. utricularia is described. The study was designed to explain the origin of the two vascular bundles present in the walls of these galls. The findings indicate that the aphid induces a massive development of the two vascular bundles present in the midvein of the leaflets of P. terebinthus: the main vascular bundle and the small supernumerary vascular bundle. Both these extremely developed vascular bundles occupy the walls of the galls induced by G. utricularia. 展开更多

Cytogenetic studies addressing the genus Pistacia are rather few. Chromosome numbers of the different Pistacia species, revealed by these studies, are questionable due to the fact that poor chromosome counting protocols were used, and these protocols are hampered by the extremely small-sized chromosomes of Pistacia species. The aim of this study was to develop a more effective method to resolve the chromosome numbers in Pistacia species using a fluorescent microscope. The method described here is modified from the Sigma Plant Protoplast Digest/Wash Solution protocol. The method used here is highly effective for karyotyping analysis and studying population genetics of Pistacia species. Moreover, it is easy and can be reproduced for other species that have smaller chromosomes. This method can be used for plant herbarium specimens or field plants. This study provides valuable chromosomal data for cytogeneticists and plant breeders who are working on this genus. It provides additional insight into understanding the taxonomic and phylogenetic relationships among Pistacia species. The chromosomes described here are also suitable for gene and genome mapping. 展开更多

The bioactive triterpenoid 3-oxo-6-β-hydroxy-β-amyrin(1)has been isolated from multiple plant sources.In this study,chloroform fraction of Pistacia integerrima extract was processed for the isolation of the compound.The compound identity was confirmed by advanced spectroscopy technique.X-ray crystallography was applied for molecular structure confirmation.In addition,compound 1 was screen for its activity on reversal of MDR(multidrug resistance)mediated by P-gp(P-glycoprotein).This was accomplished by using rhodamine123 exclusion on multidrug-resistant human ABCB1 gene transfected mouse T-lymphoma cell line.Outcomes revealed that MDR reversing effect was comparable to verapamil as positive control in vitro.Treatment of TPA-induced tumor promotion with 3-oxo-6β-hydroxy-β-amyrin led to reduction in the applied anti-tumor promotion experiment.The chemo-preventive effect of 3-oxo-6β-hydroxy-β-amyrin was comparable to curcumin as positive control based on the reduction of immediate early tumor antigen expression.Molecular docking by applying Autodock Vina 1 and i-GEMDOCK v 2.1 tools indicated that compound 1 gives good docking results,as determined by their fitness score and specificity.Moreover,results showed that compound 1 isolated from Pistacia integerrima precisely attached to a region where co-crystallized ligand for receptor previously existed.Our findings may explain the use of Pistacia integerrima plant extracts as an anticancer agent in folk medicine. 展开更多

This work was conducted to assess the anatomical features of Pistacia atlantica Desf. under Mediterranean semi-arid climate conditions. In this study, phytoecological approach was used at different observation scales including the large ecological scale. 11 samples of P. atlantica species were randomly selected in order to study the anatomy of leaves and branches. The results show that leaves have palisade parenchyma occupying almost the entire mesophyll, measuring 100 to 170 μm. While in branches, the only pith occupies 38% followed by the xylem (24%), relative to the rest of the tissue (epidermis, periderm, collenchyma, pericyclic fiber, secretory duct and phloem). The current results suggest that P. atlantica species has xeromorphic anatomical characters, giving it great ecological plasticity in an arid environment. Moreover, this study shows that the human activities are causing local extinction of this rare species in Algeria. 展开更多

This study attempts to examine the effects of salinity on leaf, stem, and nut of Pistacia vera (Ohady and Kaleh Ghochi cultivars) in order to characterize their anatomical structures with electron and light microscopy. A comparative study of the anatomy indicates a difference between the density of simple and glandular trichomes in leaf surface, deposit of wax, the thickness of leaf, the length of epidermal cells, palisade parenchyma cells, crystals in mesophyll, and the manner of compatibility to salinity. The results obtained in this research demonstrate that compatibility of Ohady cultivar is higher than Kaleh Ghochi and the degree of mechanical wounding depends on their development stages. In addition to results of previous studies which considered crop load as the main cause of fruit deformity. The present study indicates that, in spite of some reduction in total production of a tree, salinity decreases fruit deformity and to a high extent prevents the production of deformed fruit. Indeed, a remarkable reduction in production of deformed fruit will be yielded by selecting pistachio varieties which are resistant to salinity. Moreover, salinity increases the resistance of nuts to mechanical wounding. The results of this study suggest that in EC = 7.6, 12.6 deformity of nut is not related to crop load. 展开更多

The current study was carried out to determine the bioactivity of P. lentiscus leaf extracts as potential antibacterial and antioxidant properties. The plant extracts were examined for antibacterial activity against antibiotic-resistant Staphylococcus aureus, Staphylococcus haemolyticus, Pseudomonas aeruginosa, and Proteus mirabilis using the agar well method (according to the guidelines of Clinical and Laboratory Standard Institute). The antioxidant potential of 3 plant leaf extracts was determined by their ability to convert Fe<sup>3+</sup> to Fe<sup>2+</sup> and scavenge the DPPH free radical. At all concentrations studied, the methanolic leaf extract had higher total phenolic and flavonoid content, as well as stronger antioxidant and antibacterial inhibitory activity compared to aqueous extract. Our findings with P. aeruginosa were especially interesting, because this bacterium was inhibited by methanol extract than that of the reference antibiotics. The results also demonstrated a link between DPPH radical scavenging ability, reducing power, and total phenolic and flavonoid content of plant extracts (r > 0.97, R<sup>2</sup> > 0.95, P = 0.01). As a result, the methanolic leaf extract of the chosen plant might be employed as an effective antioxidant and antibacterial agent for the treatment of a variety of morbidities. 展开更多

In our context, and in the goal to valorize the Pistacia atlantica species Desfthat grows spontaneously in Algeria occidental except the coastline, and that is used by the nomadic populations in their daily consumptions, we are thinking about drying its leaves. Here, the biochemical analysis of dried leaves ofPistacia atlantica is determined, the sorption is other ms are of great importance in the food industry, especially in the drying; the sorption isotherms of pistachio leaves were measured by the gravimetric method at three temperatures 40, 50 and 60 ℃. The equilibrium was achieved after eight days for desorption and seven days for adsorption with water activity ranging from 5% to 90%. Only the GAB and Peleg models were found to be the most suitable for describing the sorption curves. The isosteric heat of sorption of Pistacia atlantica leaves decreases with an increase in moisture content and was found to be an exponential function of moisture content for adsorption and desorption. The pistachio leaves could be considered as a rich natural source of valuable nutriments (carbohydrates, proteins and lipids); lipid fraction is equal to 2.25%; proteins are the second macronutriment that predominates in these sheets: 4.35%; accordingly carbohydrates content was about 25.77%. 展开更多

Spectrophotometric analyses were employed to highlight the scavenger capacity of this oil using the 2,2-diphenyl-1-picrylhydrazyl (DPPH) test. Twenty compounds were identified by GC and CG/MS analyses, and the main part of the compounds of the oil was terpinene-4-ol (41.24%) and α-terpineol (7.31%), α-pinene (9.48%), limonene (09.11%), β-myrcene (10.5%), p-cymene (8.67%) and α-phellandrene (2.20%), β-caryophyllene (12.62%) as major compounds. The DPPH test shows that Pistacia lentiscus essential oil possesses antiradical activity. A linear correlation (correlation coefficient R<sup>2</sup> = 0.995, P Pistacia lentiscus essential oil. 展开更多
