Methods and Results: Initially, in vitro experiments were performed to determine the growth-promoting characteristics of bacteria. Then in the field, the effects of bacterial inoculation (control, Azotobacter chroococcum, Azospirillum lipoferum, Bacillus amyloliquefaciens, Bacillus sp. strain1, and Pseudomonas putida) on flax traits were evaluated at different irrigation levels (100%, 75%, and 50% crop water requirement). Bacterial treatments in the pot experiment were selected based on the field experiment results. The irrigation regimes in the pot and field experiments were the same and bacterial treatments included single, doublet, and triplet applications of the bacteria. All the bacterial strains could solubilize phosphate, produce ammonia (except for Bacillus sp. strain1), indole acetic acid, and siderophore (except P. putida). Field results indicated that the bacteria significantly mitigated the effects of water deficit. Compared with control plants, bacterial treatments increased the oil, linolenic acid, protein, and sulfur content; the number of shoots and capsules; and the harvest index in the flax plants. Pot experimental results revealed that the combined inoculations were more effective than single inoculum treatments. Accepted Article This article is protected by copyright. All rights reserved Conclusions: Bacterial inoculation alleviates deficit irrigation effects in flax plants. Significance and Impact of the Study: The effectiveness of applying A. chroococcum, B. amyloliquefaciens and Bacillus sp. strain1 was confirmed, especially as a combination to protect flax against water deficit and to improve its nutritional quality and growth.

Superabsorbent hydrogels are crosslinked hydrophilic polymers that increase soil capacity to hold water, nutrients and improve the plant's growth and yield. The aim of this investigation was to evaluate the growth parameters and essential oil (EO) content, yield and composition of lemon verbena under sole and combined application of conventional chemical fertilizers, bio-fertilizer and superabsorbent polymer. The Gas chromatography (GC) and Gas chromatography with mass spectroscopy (GC-MS) results demonstrated that oxygenated monoterpenes as the dominant class; also geranial and neral as major constituents of lemon verbena EO. Using superabsorbent hydrogel induced the highest content of geranial and neral. According to the results, although sole application of treatments was useful, their combined use was more effective to increase dry mass and oil yield of lemon verbena. Hence, the combination of chemical fertilizers plus biofertilizer and superabsorbent hydrogel can be suggested as an integrated nutrient management with the aim of optimizing the production of biomass and EO.

This study was carried out to determine the most effective indices for drought tolerance and identification of tolerance genotypes under drought conditions in N. sativa. For this purpose, 36 genotypes of N. sativa were tested as a split plot experiment based on a randomized complete block design with three replications at Agricultural Research Field of Shahrekord University, Shahrekord, Iran under two irrigation conditions (non-stress and drought stress) at 2017-2018. The results showed that there were significant differences among different genotypes in terms of all drought stress tolerance indices. A modest correlation was observed between grain yield under normal and stress conditions (R 2 = 0.43). Grain yield showed a positive and significant correlation with all indices under normal conditions, except for yield stability index (YSI). The MP, GMP and STI had positive and significant correlations with grain yield under both normal and drought stress conditions. According to principal component analysis, the first component explained about 63% of the total variation, which was correlated positively with YP, MP, GMP, and STI indices. Therefore, MP, GMP and STI could be used to select drought-tolerant genotypes. Based on the high grain yield potential and high drought tolerance observed for Nige53, Nige59 and 38923 genotypes, these genotypes could be recommended for cultivation under drought stress conditions and further studies in breeding programs.

The objective of this research was to study the feasibility of biodiesel production from mountain almond (Prunus Scoparia) oil using ultrasonic system and optimization of the process using Artificial Bees Colony (ABC) Algorithm. The results showed that by increasing the molar ratio, the conversion percentage increased and after reaching a certain ratio, further increase in the molar ratio caused decrease in the conversion percentage. Increasing in the ultrasound amplitude resulted in an increase in the conversion percentage which tends to ascend; Furthermore, results of optimization showed that the amount of molar ratio, amplitude, pulse and reaction time were 5.6, 0.90, 0.33 and 5 min, respectively. For independent variables, the values of yield and energy consumption were obtained which were equal to 96.1% and 9912 J, respectively. This finding proves that ABC...

Polyphenol content and antioxidant activity of flowers and herbage of three species of the genus ... more Polyphenol content and antioxidant activity of flowers and herbage of three species of the genus Alcea were determined. Flowers showed high total phenolic content and yielded values ranging from 26.83 (Alcea aucheri var. lobata) to 82.59 (A. aucheri var. aucheri) mg GAE/g DW. Total anthocyanin content was highest (934.98 mg/ml) in the flowers of A. auchrei var. aucheri (A12), whereas the content was minimal (1.34 mg/ml) in the herbage of Alcea koelzii (A2). The highest total flavonoid content was recorded in A. koelzii (16.15 mg Q/g DW), while the lowest value was achieved in A. aucheri var. lobata (8.06 mg Q/g DW). The highest concentration of mucilage was recorded in the flowers from Alcea arbelensis (32%), whereas those of A. aucheri var. lobata yielded the lowest value (1.05%). Principal component analysis scatter plot, derived from all data for flowers in 13 Alcea specimens revealed a different quantitative phytochemical profile. The strongest radical scavenging activity, measured by DPPH method, was recorded in A. aucheri var. aucheri with an IC 50 of 34.06 μg/ml.

Hyssop essential oil has been used as antibacterial, antifungal and as a flavoring in the food industry. The essential oils from shade drying (20-25 ºC), sun drying (under direct sunlight at 25-35ºC,) oven drying (40, 50 and 60ºC), microwave drying (300, 450 and 600 W) and infrared drying (40, 50 and 60ºC) were isolated by hydrodistillation in a Clevenger apparatus and analyzed by GC and GC/MS. The results showed a significant effect of different drying methods on the drying time, essential oil content and composition. The lowest and highest of drying time was related to microwave drying at 600W and shade drying, respectively. Based on the results, 45 compounds were identified in the essential oil. The main compound was isopinocamphone (41.94-62.25 %) followed by (E) pinocamphone (4.67-16.56 %), β-pinene (3.93-13.62 %). Overall, it can be stated that the use of infrared treatment for hyssop drying, not only reducing the relative time and uniform drying of the herbal substance, but also preserved the quantity and quality of the essential oil components.
