B. Jamali, S. Eshghi, E. Tafazoli,
Volume 13, Issue 6 (Number 6 - 2011)
Abstract
The present research was carried out under hydroponic culture to evaluate the interaction between salicylic acid (SA), nickel (Ni) on vegetative and reproductive growth of strawberry plants as a factorial experiment in a completely randomized design. Well-rooted daughter plants of Pajaro cultivar, were potted in 3 L plastic pots and were sprayed with SA at concentrations of 0, 1, 2 and 3 mM and NiSO4 at 0, 150 and 300 mg.L-1, after establishment. Results indicated that SA at 2 mM increased root and shoot fresh weight, number of inflorescences and fruits, fruit nitrogen concentration and yield. The effect of Ni was promoting too, as 150 mg.L-1 of Ni led to significant increments of fruit number, inflorescences, leaf area per plant and yield. However, the best results were found when SA was applied accompanied by Ni.

M. Abdollahi, S. Eshghi, E. Tafazzoli, N. Moosavi,
Volume 14, Issue 2 (3-2012)
Abstract
Excessive vegetative growth may bring about improper pollination and consequently lead to reduced fruit set and misshapen fruits. Paclobutrazol (PP333) reduces vegetative growth. On the other hand, balanced nutrient uptake at all developmental stages increases fruit quality and yield. An experiment was conducted with the aim of reducing vegetative growth and improving yield of strawberry, Selva cultivar, using combinations of PP333, boron and zinc. Results indicated that PP333 reduced vegetative growth by reducing both fresh and dry weights of shoots while simultaneously some such reproductive characters as inflorescence and fruit number were increased. Boron (H3BO3) alone had no effect on reproductive growth. A combination of PP333 plus B (100- 00 mg l-1) was the most effective in increasing fruit number as well as fruit weight. Paclobutrazol combined with zinc sulfate (ZnSO4) at concentrations of 100- 100 mg l-1 PP333×ZnSO4 had positive effects on reproductive growth including inflorescence number and yield. Zink sulphate at concentration of 100 mg l-1 with no PP333 and H3BO3 application increased yield, inflorescence and fruit number as compared with other treatments.

Volume 21, Issue 4 (Winter 2017)
Abstract
Housing prices in a city spatial analysis, spatial vision of the city in terms of housing prices creates existence thoroughly. Using such an analysis can be found in the city, where prices are high or low in the analysis. This study were conducted aims to achieve spatial pattern of housing prices in the city. The purpose of applied research and in terms of the nature and method is analytic. The population of the city of Tabriz in 1390, is the residential apartment. Analysis of the spatial pattern analysis is used, cluster analysis in GIS maps and kriging interpolation method. The results of index rating average nearest neighbor with standard 88/22 and P Value 000/0 shows the distribution of cluster housing prices at all levels. According to statistics of General G, P Value and Variance value is zero, indicating a cluster pattern with a high concentration. The results show that the highest concentration of hot spots hot spots (highest price) in the East part of the city with the highest concentration of cold spots (lowest price) in the north, north-western and south-western city of Tabriz. Geocaching and no points given little value estimation using kriging interpolation using adjacent areas indicate that11/34 percent of housing in Tabriz has less than a million.
The assessment of security in urban public spaces (Case Study: Tehran city parks)

Volume 22, Issue 2 (8-2018)
Abstract
 Introduction
Because of expansion of cities and increase in the population density, security is one of the basic human needs in urban life. In fact, feel safe in the city is one of the criteria for urban development, considered as a measure of the effectiveness in urban development programs, affects citizens' behaviors and dynamism of the city. Today is considered as one of the important indicator in the quality of urban life and will increase the comfort and welfare of citizens and accept the work, commitment and responsibility. In fact, since one of the most important criteria and factor in discussions related to social aspects of sustainable development is to encourage citizens to participate in urban spaces and to strengthen social interactions in these areas, it is necessary to identify and eliminate barriers to such presence. Security promotion methods have become one of the main priorities of urban professionals and theorists. Factors that eliminate urban security, threaten or reduce the security of the cities are many, and some urban spaces, especially public spaces, such as parks, are one of the main threats to urban security. These spaces are usually considered to be cozy and safe spaces for illegal and abusive activities. Therefore, leisure life is among the most important spheres of people's lives influenced by the feeling of security. Parks, as one of the most important urban uses, play a major role in the realization of leisure and recreational activities for citizens living in urban areas, and are visited by many people daily.
 
 Methodology
The method of this research is descriptive-analytic with a purposeful purpose. To evaluate the safety of the parks 24 indicators are used. The required data of the research are derived from the performance statistics and arrest of the Tehran Municipality Protection Unit at parks level, published in the statistical journal of Tehran. In order to determine the importance of each of the indicators, the network analysis model (ANP) and for analyzing the data, the Promethean model and the GIS software are used. In the first stage, after analyzing the data, parks are classified into five groups with high, moderate, low, very low security and lack of security. The output from this step is mapped in the GIS software environment. The second stage involves identifying the disruptive factors of security and distribution of factors in the level of parks in Tehran. In the final stage, using the Google Earth software, the position of the studied parks is determined and spotted on the map of Tehran. After creating the layer, the information is added to the layer descriptive information table. After preparing the layer using the interpolation model, estimates of the kernel density of the areas where the most insecurity factors occurred are identified and their distribution is identified on the map.
 
 Results and discussion
24 indicators have been used to assess the security of parks in Tehran. The total safety margin in 2014 at 41 of the studied parks is 17883. The most common cause of insecurity is related to the issuance of a bill for communicating social security offenses with 11678 cases, arrests of addict 1490, the arrest of alcoholic beverages 984, seizure of motorcycles 787, rejection of bribes 771, seizure of vehicles 760, arresting conflicts 397, perpetrators of monkery crimes 269, arresting artillery and firearms 126, arresting the burglar with 114 Case and other factors are 498 cases. Except for the issuance of social security vehicle social security offenses, respectively, the factors mentioned above are 24, 16, 13, 13, 12, 8, 6, 4, 2, and 2 percent of the insecurity factors in the park.
Conclusion
According to the results of the studies carried out in the study based on the crimes that occurred in 2014 in 41 parks with regional performance in Tehran, Sahand, al-Ghadir, Sa'adat Abad, Misagh, Shafagh and 22 Bahman parks with a value of Phi between 300/0 to 600 / 0 with high security, Artists, Niavaran, Thesis, Meyad, Flight, Bahman, Shariati, Jamshidieh, Saee, Razi, Narges, Fadak, Basij, Darband, Ghaem, Koohsar, Knowledge, Mahdi and Darabad with a Phi value of 0 to 300/0 with Medium Security, Bahiar, Behsat, Mellat, Park City, Derek, Resort, Tulip, Persian Gulf and Nahjul Balaghah with values of Phi between 0 and 300/0-lower, Azadgan, Student, Provincial and police with Phi values between -0.300 and -0.600- Very low security And Lovazan, Chitgar, Sorkha Hessar, , are unprotected with a value of Phi of over 600/0. Sahand Park with the value of Phi is equal to 416/0 and Sorkheh Hesar Park with a value of Phi is 728/0. Sahand Park has the least amount of addict arrest, the arrest of Kharv and alcoholic beverages, the arrest of conflict and conflict, the arrest of social misconduct and fraud, and the rejection of bribes and acts of punishment. In front of Sorkheh Hesar Park, it has the most deplorable arrest, arresting a force mausoleum, suspecting a force majeur, arresting thugs, arresting CDs illegal sale. In the sequel, the GIS is used to show the most insecure areas, used to interpolate the kernel density. A map of the density of the entire crime occurred in the park. The results of the interpolation of the kernel density indicate that the parks in central parts of Tehran have moderate security the northern and southern parts have high security and parts of East and West of Tehran are unprotected. Also, according to the directional distribution map, the distribution side is the most insecure factors in the parks of Tehran in the east and west of Tehran.

Role of Seed and Gibberellic Acid on Return Bloom in Olive (Olea europaea L. c.v. ʻTokhme Kabkiʼ)
M. Zare, M. Rahemi, S. Eshghi,
Volume 25, Issue 5 (9-2023)
Abstract
Alternate bearing is one of the most important problems in olive production around the world. This experiment was performed on 25-year-old olive trees of Tokhme Kabki cultivar in an olive orchard located in Shiraz, in 2018-2019. In this experiment, the role of normal fruits, shot berries, fruit removal, and Gibberellic Acid (GA3) application on the amount and type of return flower were determined. We demonstrated that seed has a significant role in flower induction in olive. Shot berry fruits actually induced return bloom and removing the fruit before pit hardening stimulates induction of flower bud in ʻTokhme Kabkiʼ olive cultivar. GA3 application before pit hardening significantly inhibited flower formation. Endogenous GA3-like substances was also determined in fruit flesh and seed tissues support the idea that, high concentration of GA3-like during pit hardening is responsible for the inhibition of flowering. According to the rapid increase in GA3-like substances in the fruit tissues, it appears that this compound may be transferred to the buds and then directed toward vegetative growth. Data suggest that GA3-like level in the fruit flesh and seed tissues is one of the main factors in alternate bearing of olive tree. Therefore, thinning the seeded fruit till 6 weeks after full bloom or before pit hardening would be effective in reducing the concentration of GA3 in the olive tree and reducing the severity of alternate bearing.

Hikmatullah Hikmat, Maryam Haghighi, Hamid Reza Eshghizade, Golnoosh Banitalebi,
Volume 27, Issue 1 (12-2025)
Abstract
This study aimed to investigate the effect of salinity on morphological and physiological traits of native Iranian melon landrace and Afghan melon cultivars using a Randomized Complete Block Design in three replications. Two salinity levels (2 and 8 dS m-1, NaCl) and 39 cultivars from Iran and Afghanistan were studied. PCA comparisons were done between morphological and physiological parameters. The sensitive and tolerant cultivars were chosen based on proximity to high yield, morphological characteristics, and distance from stress indices. The biplot results showed a high correlation between vitamin C traits with soluble solids, proline, and relative water content, and a negative correlation with Fv/Fm ratio. These indices are good indicators for identifying saline resistance cultivars. Salinity stress increased electrolyte leakage, proline concentration, total antioxidant activity, sodium content, vitamin C, organic acid, and total soluble solids. In addition, salinity decreased the yield, mean fruit weight, firmness, fruit length, fruit width, internal cavity length and width, flesh thickness and fruit peel thickness, Fv/Fm ratio, greenness index, relative water content, and leaf potassium. The highest concentrations of sodium were found in the Gorgi Shirdan Jorgeaval cultivar under salinity, while the highest concentrations of potassium were found in the Torkamani cultivar under non-saline conditions. Analysis revealed two types of Torkamani and Zanki melon, which are recommended to plant in saline conditions.
