Dust is considered as one of the most widespread air pollutants. The objective of the study was to analyze the effect of dust load on the leaf attributes of the nut pistachio tree (Pistacia vera L.) planted in Badrood region (Kashan, central Iran) with a relatively high aeolian dust pollution. Some leaf characteristics including specific leaf area (SLA), relative water content (RWC), leaf nitro...

This study was carried out in two years, 2012 and 2013, to determine the effects of salinity and different kochia plant densities on yield and some physiological characteristics of sorghum (cv. Sepideh) at Salinity Research Center, National Salinity Research Center, Yazd, Iran. Treatments consisted of water salinity levels: 2 (control), 6, 10, and 14 dS m-1 of NaCl as main plots and different k...

Water scarcity causes production losses in arid and semi arid regions. In this condition, deficit irrigation is one of the most important methods to minimize effects of water shortage. This research was conducted to evaluate the effects of two kinds of irrigation management (deficit irrigation and partial rootzone drying technique) on some of physiological and phenological characteristics and w...

In order to investigate the effect of Piriformospora indica endophyte fungi on quantity and quality of peppermint essential oil and physiological parameters under salt stress, An Research Field experiment of Agricultural Sciences and Natural Resources University of Surrey in 2015 was conducted. Experiment arranged in completely randomized design with three replicates. The experiment was done in...

This research was carried out in a factorial split plot experiment based on a randomized complete block design with four replications in Semnan Agriculture Research Center, Bastam, central Iran, in 2019. Experimental treatments included irrigation as the main factor at three levels of 100, 75 and 50% of water requirement and sub-factors including cultivar at three levels (Titicaca, Q26 and Q29)...

in this project, some new polyaspartimides, (pas)s, have been synthesized form michael addition reaction between new synthetic bismaleimide (bmi) and some aromatic diamines. a characteristic property of this polyaspartimides is a pendent carboxylic group, which introduced to these polymers from new bismaleimide. bismaleimides (bmi) is one of the interesting compounds, which can be self-polymeri...

cultural iran is a scope that is more extended than the political territories of iran as a political unit. this concept means that cultural geography(mehdi moghanlo-1383-1) of iran is greater than its political geography which, according to history, has a long history extending west-east from kandahar to the euphrates and north-south from the persian gulf to the caucasus including transoxiana a...
