By using the non-destructive CT method a total of 81 healthy pears was selected and then subjected to quasi-static and dynamical loading. The experiment was performed on wide edge quasi-static pressure of 70, 100, 130 N and thin edge of 15, 20, 25 N and dynamic load of 300, 350, 400 g and storage period for 5, 10 and 15 days, to investigate the different effects of loading forces and storage periods on the percentage of the bruise and its relation with the qualitative properties such as phenol, antioxidant and vitamin C contents and firmness. The results of the experiments showed that the highest and lowest percentages of the bruise were related to a load of 400 N of 15 days and a 15 N 5-day thin line with values of 47.36 and 0.007, respectively. The highest and lowest physiological values were 15 N load of the 5-day thin edge and the 400 N of 15-day impact. Finally, the highest antioxidant content was 51.5% for 300 g dynamic loading force and 5- day storage, 28.86 mg/100g phenol for loading force of 70 N wide edge and 5 day storage and 7.4 mg/100ml vitamin C for loading force of 70 N wide edge and 5 day storage. Finally, according to the obtained results, there was an inverse relationship between the amount of bruising and chemical properties of pear.University of Tehran, College of AburaihanInternational Journal of Horticultural Science and Technology2322-14616220191201Anatomical and Morphological Properties of Trichomes in Four Iranian Native Salvia Species under Cultivated Conditions1892007395910.22059/ijhst.2019.281162.296ENGhasemEsmaeiliDepartment of Horticulture Science, Faculty of Agriculture, Ferdowsi University of Mashhad0000-0002-9189-4817MajidAziziDepartment of Horticulture Science, Faculty of Agriculture, Ferdowsi University of Mashhad0000-0002-8813-4518HosseinArouieeDepartment of Horticulture Science, Faculty of Agriculture, Ferdowsi University of Mashhad0000-0002-5493-8200JamilVaeziDepartment of Biology, Faculty of Science, Ferdowsi University of Mashhad0000-0002-6931-6754Journal Article20190512The morphological specifications play a substantial role in classification and breeding programs of various plant taxa. In the current study, some macro- and micro-morphological features of <em>Salvia nemorosa</em>, <em>Salvia syriaca</em>, <em>Salvia frigida</em> and <em>Salvia virgata</em> (three accessions), were investigated using scanning electron microscopy and image analysis program. The completely randomized design (CRD) was used to compare the morphological properties (r=4). Macro-morphological and agronomical measurements showed that <em>Salvia</em> species have great potential for cultivation as medicinal and ornamental plants. The cluster analysis suggested that <em>S. virgata</em> and <em>S. frigida</em> located in the same group; on the other side, <em>S. syriaca</em> and <em>S. nemorosa</em> had more similarity. The micro-morphological results showed that glandular trichomes (GTs) and non-glandular trichomes (NGTs) were widely distributed over the leaf and flower surfaces. The peltate GTs with high-density covered sepal and petal and were observed with low density on the leaves. The comparison with different species showed that the highest size and density of GTs belonged to <em>Salvia virgata.</em> The GTs are large and cover a significant portion of the flower surface (3.85-18.45%). The multicellular GTs were observed in <em>S. nemorosa</em> and <em>S. virgata</em> A<sub>1</sub> and A<sub>2</sub>. The uniseriate and multicellular NGTs covered the adaxial leaf surface in different species. Besides, relative variation in GTs was observed in the three studied <em>S. virgata</em> accessions (15.33- 30.58 trichomes per mm<sup>2</sup>), which indicates the role of environmental conditions in trichomes formation. A wide range of variation in most of the micro- and macro-morphological traits of <em>Salvia</em> genotypes observed in cultivated condition.University of Tehran, College of AburaihanInternational Journal of Horticultural Science and Technology2322-14616220191201Ecological Factors Regulate Essential Oil Yield, Percent and Compositions of Endemic Yarrow (Achillea eriophora DC.) in Southeast Iran2012157396010.22059/ijhst.2019.283276.299ENMarziehEtehadpourDepartment of Horticulture, Faculty of Agriculture, Shahid Bahonar University of Kerman, Kerman, Iran

The impact of climatic and edaphic conditions was investigated on essential oil (EO) yield and compositions of different yarrow ecotypes, native to Kerman province in southeast of Iran. The aerial part of plants was collected from 13 naturalhabitats. Gas chromatography-mass spectrometry (GC-MS) analysis revealed a significant variation in EO yield and compositions among ecotypes. 116 components were identified from 13 regions. EO extraction yields fluctuated from 0.71 to 5.83% (v/w) in KP12 and KP02 regions, respectively. The predominant components were L-borneol (0-45.93%), bornyl acetate (0-22.45%), bornyl ester (0-10.46%), (E)-α-ionol (0-28.77%), 6βBicyclo [4.3.0] nonane5β-iodomethyl-1β-isopropenyl-4α, 5α-dimethyl (0-12.14%) and eucalyptol (0- 3.96%). For the first time, the presence of hexadecenoic acid, 6β-bicyclo [4.3.0] nonane and 5β-iodomethyl-1β-isopropenyl-4α, 5α-dimethyl were reported in <em>A. eriophora</em>. EO yields and compositions were affected by the ecological factors. Among them, soil pH and latitude showed the most significant impacts.University of Tehran, College of AburaihanInternational Journal of Horticultural Science and Technology2322-14616220191201Effects of Growth Stimulator Microbes on Growth and Ions Concentration of Stevia under Salinity Stress Conditions2172367396110.22059/ijhst.2019.280185.292ENArezouForouziGorgan University of Agricultural Sciences and Natural Resources, Gorgan, Golestan, IranAzimGhasemnezhadGorgan University of Agricultural Sciences and Natural resources, Gorgan, Golestan, IranRezaGhorbani NasrabadGorgan University of Agricultural Sciences and Natural Resources, Gorgan, Golestan, IranJournal Article20190428Soil salinity and water deficit are major problems for development of agricultural production. In this study, effects of growth promoting microorganisms (inoculation with <em>Piriformospora indica</em> and two isolates of <em>Streptomyces</em> <em>sp</em>.) on the leaf yield and absorption rate of some elements in leaves and roots of stevia plant was investigated under salinity conditions for two consecutive years (2016-2017). The fresh and dry weights of the leaves were significantly affected by microorganism and salinity. High salinity level led to sodium accumulation in the root and leaf; while the amount of potassium and K<sup>+</sup>/Na<sup>+</sup> ratio decreased in both root and leaf. The accumulation of phosphorus in both leaf and root was significantly decreased in 3 ds m<sup>-1 </sup>salinity. Plants exposed to <em>Piriformospora indica</em> and <em>Streptomyces</em> strains, showed lower sodium content in their leaves and roots. In contrast, an increase in the content of potassium and phosphorus was observed in the growth stimulator microbes-treated plants. However, the K<sup>+</sup>/Na<sup>+</sup> ratio in the growth stimulator microbes-treated plants was to some extent lower than its ratio in control plants. In conclusion, <em>P. indica</em> and <em>Streptomyces</em> strains improved the biomass formation of the stevia plant under salinity conditions by controlling the uptake of potassium, phosphorus and sodium.University of Tehran, College of AburaihanInternational Journal of Horticultural Science and Technology2322-14616220191201Effect of Ultrasonic Atomizer on the Yield and Yield Components of Tomato Grown in a Vertical Aeroponic Planting System2372467396310.22059/ijhst.2019.278366.284ENAmin RezaJamshidiDepartment of Agricultural Mechanization, Shoushtar Branch, Islamic Azad University, Shoushtar, IranAhmadGhazanfari MoghaddamDepartment of Agricultural Machinery Mechanics, College of Agriculture, Shahid Bahonar University of KermanAhmad RezaOmmaniDepartment of Agricultural Management, Shoushtar Branch, Islamic Azad University, Shoushtar, IranJournal Article20190324Aeroponic planting is proved to be the one of the most efficient growing environments for many vegetable crops. In this technique, plants are cultivated in absence of soil and the required nutrients are directly supplied to the roots through a fogging system. In modern sprayers, water is atomized by means of ultrasound waves. The aim of the present study was to investigate the effect of ultrasound waves on the nutrient solution and on yield and some yield components of tomato grown in a vertical aeroponic planting system. The investigation was conducted using a 3×3 factorial experiment based on a completely randomized design. The considered factors were ultrasonic frequency at three levels of 50 kHz, 107 kHz and 2.1 MHz and the fogging duration at three levels of 10, 15 and 20 min. The results indicated that, at frequency of 50 MHz, the nutrient solution had the lowest EC equivalent while the pH of the nutrient solution reached its highest value at 2.1 MHz. Generally, both EC and pH value of the nutrient solution were elevated by increase in the wave frequency, but they did not show a definite trend by changes in fogging duration. The ANOVA indicated that the interaction effect of the ultrasound frequency and fogging period had significant effect on the plant height, root weight and length, fruit weight, fruit length, plant yield and system performance. In general, the measured yield components decreased as frequency of the waves increased and the best results were obtained at 50 kHz frequency and 15 min fogging period.<br /><strong> </strong>University of Tehran, College of AburaihanInternational Journal of Horticultural Science and Technology2322-14616220191201Yield, Leaf Mineral Content, and Quality Properties of Hayward Kiwi fruit as Influenced by Different Fertilization Methods2472577396410.22059/ijhst.2019.283945.300ENTaherehRaiesiCitrus and Subtropical Fruit Research Centre, Horticultural Science Research Institute, Agricultural Research and Education Organization (AREO), Ramsar 46915, Iran.0000-0002-9773-6422BijanMoradiCitrus and Subtropical Fruit Research Centre, Horticultural Science Research Institute, Agricultural Research and Education Organization (AREO), Ramsar 46915, Iran.JavadFatahi MoghadamCitrus and Subtropical Fruit Research Centre, Horticultural Science Research Institute, Agricultural Research and Education Organization (AREO), Ramsar 46915, Iran.Journal Article20190624Kiwifruit requires a high quantity of nutrients that must be supplied through fertilization to obtain an optimum yield on a sustainable basis. This research was conducted to evaluate different fertilization methods including broadcast application (as control), deep placement of the fertilizer and fertigation, alone or in combination with foliar application and their effects on the yield, leaf mineral contents, and some quality properties of kiwifruit (<em>A. deliciosa</em> cv. Hayward). Results showed that fertilization methods had a significant effect on yield and the highest level of yield (76 Kg tree<sup>-1</sup>) was obtained in the combination of fertigation with foliar spray. In addition, foliar application significantly increased leaf mineral contents of kiwifruit in all treatments. Furthermore, the fertilization method had significant effects on phenol, ascorbic acid contents, and antioxidant capacity of fruits. The highest levels of antioxidant (70.9%), phenol (103.6 mg 100g<sup>-1</sup>), and ascorbic acid (54.2 mg 100 g<sup>-1</sup>) in fruits were recorded in ‘soil application’ method. Total soluble carbohydrate and starch contents of the fruits were reduced following foliar nutrition in all treatments. However, foliar nutrition significantly increased fruit crude protein. In conclusion, based on obtained results, fertilization method directly influenced the yield and leaf mineral status and indirectly influenced the fruit chemical composition of Hayward kiwifruit. In fact, the supplemental foliar application reduced some fruit quality attributes (lower antioxidant activity and carbohydrate content) but enhanced the yield of kiwifruit.University of Tehran, College of AburaihanInternational Journal of Horticultural Science and Technology2322-14616220191201Characterization of Four Famous Red Grapevine Cultivars2592727396610.22059/ijhst.2019.284658.305ENFatemehRoshani BakhshM.

DNA sequencing and alignment analysis of <em>F</em>3<em>H</em>, <em>UFGT</em>, <em>DFR</em>, and <em>MybA</em>1 gene sequences showed that there was high homology (>%99) among the studied cultivars, therefore it can be concluded that they are derived from a common ancestor.University of Tehran, College of AburaihanInternational Journal of Horticultural Science and Technology2322-14616220191201The Effects of Simulated Vibration Stress on Plant Height and Some Physical and Mechanical Properties of Coleus blumei Benth2732827396710.22059/ijhst.2019.282693.298ENAtefehSafaei FarDepartment of Horticultural Sciences, Faculty of Agriculture, Lorestan University, Iran.AbdolhosseinRezaei NejadDepartment of Horticultural Sciences, Faculty of Agriculture, Lorestan University, Iran.FeizollahShahbaziDepartment of Biosystem Engineering, Faculty of Agriculture, Lorestan University, IranSadeghMousavi-FardDepartment of Horticultural Sciences, Faculty of Agriculture, Lorestan University, Iran.Journal Article20190421Non-chemical control of plant growth is an important goal for the production of ornamental pot plants. In the present study the effects of simulated vibration on plant height and some physical and mechanical properties of Coleus stem were investigated. The study was conducted as a factorial experiment based on a completely randomized design with three replications. Vibration stresses were performed using a laboratory vibration simulator and the effects of vibration parameters such as frequency and duration on the stem characteristics of Coleus plants were examined. Vibration frequency included three levels of 7.5, 10 and 12.5 Hz and vibration duration included three levels of 0 (control), 5 and 10 min. Based on the obtained results, vibration stress caused significant decrease in the height and surface area of the stems. Vibration frequency of 12.5 Hz with 10 min duration caused 31% decrease in plant height in comparing to the control samples. Mechanical properties of stems including modulus of elasticity, bending force, and bending stress were reduced by increasing vibration frequency and duration when compared to the control samples. In conclusion, the results of the current study indicated that vibration stress on Coleus decreased plant height while increased the elasticity and resistance to the fracture caused by mechanical forces of the stem.<br /><strong> </strong>University of Tehran, College of AburaihanInternational Journal of Horticultural Science and Technology2322-14616220191201Enhancing the Quality and Yield of European Borage (Borago officinalis) by Simultaneous Application of Granulated Compost, Vermicompost and Mycorrhiza2832987396910.22059/ijhst.2019.274604.281ENZahraShahbaziDepartment of Agronomy, Yasouj University, IranAminSalehiDepartment of Agronomy, Yasouj University, IranSaeidHazratiDepartment of Agronomy, Faculty of Agriculture, Azarbaijan Shahid Madani University, Tabriz, Iran0000-0001-6239-6416MohsenMovahedi DehnaviDepartment of Agronomy, Yasouj University, IranJournal Article20190216The application of organic fertilizers alone or in combination with bio-fertilizers is important for sustainable agriculture, healthy agricultural production and restoring soil quality. Compost, vermicompost and mycorrhiza amendments could improve soil quality and plant yield. However, little is known about their impact on yield and quality of European borage (<em>Borago officinalis </em>L.). To evaluate the effects of vermicompost, granulated compost, and mycorrhiza on qualitative and quantitative traits of <em>B. officinalis</em> an experiment was carried out based on a randomized complete block design arranged in a factorial experiment with three replications. Organic fertilizers in five levels (0, 5 and 10 t/ha vermicompost and 3 and 6 t/ha granulated compost) and mycorrhiza (<em>Glomus mosseae</em>) in two levels (with and without) were considered. It was shown that the effects of organic fertilizer and mycorrhiza application on nitrogen content were significant in such a way that the maximum nitrogen content was obtained by 10 t/ha vermicompost and mycorrhiza inoculation treatment. The main effects of organic fertilizer and mycorrhiza on phosphorus and potassium contents were also significant. The maximum values were obtained when 10 t/ha vermicompost and mycorrhiza were applied together. Total chlorophyll content, flower-bearing branches, mucilage, and phenol were measured in all three harvests. The results indicated that the interaction effect of harvesting time, organic fertilizer, and mycorrhiza was only significant on chlorophyll content. The maximum chlorophyll content (0.958 <em>mg</em> <em>g</em><sup>-1 </sup>freshweight) was detected in the third harvest when 10 t/ha vermicompost and mycorrhiza were applied. Maximum mucilage content (4.23%), phenol content (5.07%) and flower-bearing branches (57.45 g m<sup>-2</sup>) were obtained by 10 t/ha vermicompost treatment. The results suggested that chemical fertilizers could be replaced by organic fertilizer and mycorrhiza to reduce soil and water contamination in the agroecosystems.
