Investigation of biochemical properties and enzymatic activity of different plant genotypes under drought stress conditions can identify tolerant genotypes to abiotic stresses. In the present study, the effect of drought stress on the activity of antioxidant and biochemical enzymes at leaves of 10 bean genotypes at different water stress levels was investigated as a factorial experiment in a randomized complete block design with three replications in the research greenhouse of University of Tehran. Compared to normal moisture conditions, when drought stress increased, the total protein content decreased and Khomein genotype had the lowest total protein content among other genotypes at 25% of field capacity stress. The highest catalase activity was observed at COS-16 genotype (0.196 mg/min protein) at irrigation level of 75% of field capacity, ascorbate peroxidase (0.226 mg/min protein) at 50% of field capacity and guaiacol peroxidase at the irrigation level of 75% of the field capacity (0.293 mg/min protein). Increasing the activity of polyphenol oxidase enzyme and proline content in severe stress compared to normal moisture conditions showed that increasing the content of these two enzymes can be a reason for increasing plant tolerance to drought stress. COS-16 genotype had the highest polyphenol oxidase activity (0.183 mg/min protein) at 25% of field capacity. Also, increasing trend of malondialdehyde content in leaves was observed under severe stress. Based on the results, among the studied genotypes, COS-16 was identified as tolerant genotype and Khomein genotype was drought sensitive. Abiotic stresses have major impacts on crop growth and yield.

Salinity at 3 levels (eight, 12 and 16dS m-1) as the main plots and 13 chickpea genotypes at sub-plots were the experimental treatments. At levels eight and 12dS m-1 salinity, MCC606 and MCC643 genotypes had the highest survival percentage and at 16dS m-1 salinity level, only MCC539, MCC606 and MCC658 genotypes survived. Relative water content (RWC), membrane stability index (MSI) and chlorophyll a concentration were decreased in all genotypes as salinity level increased. Among the genotypes, MCC606 had the highest values of RWC, MSI and carotenoids at levels 12 and 16dS m-1 salinity. Proline content was increased in all genotypes as salinity level increased from 8 to 12dS m-1. Results of the cluster analysis indicated the superiority of MCC539, MCC658 and MCC606 compared to total mean in all parameters. Principal component analysis showed that the first component explained 64.49% of changes in DPPH, carotenoids, MSI and biomass in MCC539, MCC658 and MCC606 genotypes. Since this experiment was conducted in controlled conditions, field assessment of freezing tolerance of the superior genotypes is recommended to confirm the results of the present study.

The results showed that oil percentage was affected by the application of iron fertilizer with different concentrations (iron chelate and nano- chelate) and its consumption time, except for the 1 g.L-1 iron chelate fertilizer, which the time of fertilizer application did not affect the percentage of rapeseed oil. Application of 1 g.L-1 iron chelate in the vegetative growth stage and also the beginning of flowering (delayed foliar spraying) were the superior treatment to increase the percentage of rapeseed oil, so that it increased 77% and 75% of the oil content compared to the control treatment, respectively. The highest amount of cis-9-oleic acid was observed with the application of 1 and 2 g.L-1 iron chelate in the vegetative stage (54.3% and 35.4% increase compared to the control). The superior treatments increasing the amount of linoleic acid were 2 and 1 g.L-1 iron chelate in the vegetative growth stage (11.62 and 12.55% increase compared to the control, respectively). Application of 2 g.L -1 nano-iron chelate in the vegetative growth stage and 3 g.L-1 nano-iron chelate in the beginning of flowering (with 5.3 and 4.5% increase compared with the control, respectively) produced the highest amount of palmitic acid. According to the results, to increase the unsaturated fatty acids such as oleic and linoleic acids, foliar application of iron fertilizer in the form of chelate in the vegetative stage is recommended.

Journal Article 2021 04 27 To investigate the effects of mycorrhizal fungus and superabsorbent on corn growth traits and yield components under water stress conditions, a factorial split plot experiment based on a randomized complete block design was conducted in Hamadan province in 2019. Low irrigation treatments including optimal irrigation (irrigation at -3bar soil water potential), moderate drought stress (irrigation at -7bar soil water potential) and severe drought stress (irrigation at -11bar soil water potential) were the main plots and mycorrhizal and superabsorbent polymer biofertilizer, their combination and control (no mycorrhiza and superabsorbent) were sub plots. . The results showed that plant height, leaf area index, ear length, ear periphery, row number per ear, number of seeds per row, 100 seeds weight, grain and biological yields and harvest index were significantly affected by superabsorbent and mycorrhizal application. By increasing the drought stress intensity, the growth and yield components decreased, but the decrease was significantly lower compared to the mycorrhiza and superabsorbent polymer applications. Mycorrhiza and superabsorbent applications in severe stress condition could increase biological yield by about 12% and 22% as compared to control. Lowest grain yield (4.25 t/ha) was obtained by severe stress without application of bio-fertilizer and superabsorbent. In general, mycorrhiza and superabsorbent applications had no significant effect on growth and biological and grain yields in the absence of stress and normal irrigationcorn; however under water stress conditions, it had significant effects on growth traits and yield, while with increasing stress intensity, this ability increased and with their combined application, these effects intensified.

Based on biplot analysis, G12, G16, G14, G9, G6 and G11 genotypes, had higher yield stability in addition to the highest seed yield. Based on different values for seed yield and weighted average of absolute scores of best linear unbiased predictions (WAASB), G11, G9, G18, G10, G13, G12, G16, G14 and G6 genotypes were high yielding and stable. The superior genotypes based on multi-trait selection index (MTSI) were G2, G18 and G6. The harmonic mean and relative performance of genotypic values (HMRPGV) introduced G14, G6 and G9 genotypes that had high stability and compatibility in addition to high seed yield. Overall, based on all analyzes and indices, G6 genotype identified as the most stable genotype and could be a candidate to introduce a new cultivar.

Irrigation treatments included normal irrigation and irrigation up to the flowering stage was the main plots and barley cultivars (Sahand, Bahman, Makui and Valfajr) were subplots. The results showed that 1000-grain weight of cultivars decreased 21.45% under stress conditions by compared to normal irrigation. Makoei cultivar had the highest decrease in grain yield with 23.55% reduction compared to other cultivars. Bahman and Makoei cultivars had the highest biological yield reduction. The highest biological yield was observed in Bahman cultivar under normal irrigation conditions. Under stress condition, the rate of remobilization increased in all parts and internods of the stem and cultivars. All cultivars had differences in the rate of remobilization from different parts of the stem, so that in the case of Valfajr and Sahand cultivars, the rate of penultimate remobilization was higher than peduncle. Bahman and Makui cultivars had high remobilization rate from peduncle and lower stem internodes. The remobilization efficiency of different stem internods had significantly increased under stress condition and the highest contribution of peduncle remobilization was obtained by Sahand cultivar under water stress conditions. Therefore, baseb on the yield indices and rate of remobilization of photosynthetic materials, Bahman and Sahand were identified as suitable barley cultivars under normal irrigation and water stress conditions, respectively.

Journal Article 2021 05 01 A field experiment was carried out as a split-plot based on an RCB design with three replications in 2020. Treatments were four levels of water supply (irrigation after 70, 100, 130 and 160 mm evaporation from class A pan) as main plots and three levels of foliar application (control (water spray), foliar application of 1 mmol salicylic acid (SA) and 1 μmol brassinosteroid (BRs) as sub plots. Water deficit stress resulted in 20.6% and 21.6% decrease in chlorophylls a and b content, and 62.9% increase in leaf carotenoids, but leaf proline content increased under water stress. The mean chlorophyll a content increased (11.4%) with SA application. Decreasing water availability increased the activity of catalase, peroxidase, and ascorbate peroxidase and polyphenol oxidase by 3.2, 1.7, 1.9 and 3.1 times, respectively. The activity of these enzymes increased by 14.4, 16.6, 8.8 and 6.8% respectively with SA application and increased by 17.6, 12.2, 8.8 and 19.9% respectively by BRs application. Grain yield and oil percentage and yield of coriander seed decreased under drought stress (75.1% and 15.4%, respectively), which resulted in a decrease in oil yield (78.9%). Oil yield was increased by SA and BRs (22.4 and 11.2% respectively). SA foliar application showed a significant advantage in comparison to BRs in the most of the traits, especially grain yield. Therefore, the application of SA can be introduced as a suitable treatment to improve coriander grain and oil yield.

(family Lamiaceae) is considered for its valuable medicinal compounds such as nepetalactone and is growing in several parts of Iran. In order to study existing genetic variation within and between populations for the first time, this research was performed on two populations of this species to investigate the genetic architecture of existing variation of the two populations. In this regard, at full maturity, open-pollinated seeds were collected based on single plants from two habitats of the species, during 2018, to be investigated as the half-sib families. Field experiment was performed in a randomized complete block design with three replications, in which eight morphologic characters were recorded on 277 single plants from 20 half-sib families of the two populations. Genetic variance components were estimated using biometrical variance components of the two populations, so that heritability of the characters were also estimated. Results of analysis of variance showed that family effect component was highly significant for majority of the studied traits of two populations. Based on the genetic variance components, the family component of variance was more effective than progeny component for the first population in plant height, crown diameter and biomass yield traits. Almost the same situation with minor differences was observed on the second population. In spite of small size of the studied populations, high heritability values of several traits indicated their suitable genetic potential. Although significant genetic variation and high heritability values were observed in the most studied traits, low heritability values of some other traits indicated the necessity of reconsidering the management on the natural populations. Constituting artificial gene pools, using the families with high performances could be a dual purposes strategy, in order to conserve the valuable gene pool as well as utilizing their potentials in breeding programs.

For this purpose, 20 barley genotypes were investigated at five tropical research stations of Iran during the 2018-2020 cropping seasons in a RCBD with three replications. Stability analysis was performed using two set of stability models including parametric statistics and REML/BLUP-based statistics. The results of parametric were pooled in genotype SIIG as a unique stability index. Morpho-phonological data were analyzed using the path analysis. The days-to heading (X1) and maturity (X2), plant height (X3), and 1000-kernels weight (X4) were considered to be sequential traits for the development of grain yield productivity (Y). Based on the results, G6, G2, G3, G5, G13, G17, G11, G12 and G14 genotypes with greater grain yield than average grain yields and high values of stability statistics were identified as desirable genotypes in terms of yield performance and stability. Furthermore, three BLUP-based statistics, HMGV, RPGV and HMRPGV, recognized G20, G6, G2, G3, G11, G12 and G17 genotypes as the high-yielding and stable genotypes. In total, G6, G3 and G11 lines, which were superior in both methods, were selected.

The main factor was tillage in two levels (no-tillage and conventional tillage) and the second factor was irrigation in three levels (without, moderate and severe water stresses based on 75, 110, and 150 mm evaporation from evaporation pan surface, respectively). The results showed that the effect of tillage on grain yield and water use efficiency was significant at 1% and 5% of probability levels, respectively. Also, the effect of irrigation levels on plant height, grain number per panicle, grain and biological yields, and water use efficiency was significant at 1% of probability level and on 1000-grain weight at 5% of probability level.

Journal Article 2021 02 04 The aim of this study was to investigate the effect of Trichoderma species and mycorrhizal fungi on increasing yield,and percentage and amount of dill essential oil in greenhouse conditions. For this purpose, a factorial experiment was conducted in a randomized complete block design with three replications. For this experiment, the roots of two Anethum graveolens (Dill) species i.e. Tabriz local cultivar and Long Island of Mammoth, were treated with the inoculums of Trichoderma isolates (Trichoderma harzianum Na-1ac and T. longibrachiatum BZ4-4) and two species of Mycorrhizal fungi (Rhizophagus irregularis and Glomus verciform). The results of this study showed that the highest chlorophyll index (4.03) was related to T. harzianum and the lowest (2.27) was related to G. verciform. Also, the highest (11.28µg/ml) and the lowest (2.36µg/ml) chlorophyll b were obtained from T. harzianum × local cultivar of Tabriz and T. longibrachiatum × local cultivar of Tabriz, respectively. The highest (77%) and the lowest (29%) percentages of colonization was observed in Long Island × R. irregularis cultivar and local cultivar × G. verciform treatments, respectively. In terms of essential oil content, the highest and the lowest percentage of essential oils were 2.39% and 0.7%, related to T. harzianum and G. verciform fungus, respectively Interaction effects (cultivar × fungus) were also significant on chlorophyll a and b and carotenoids and increased them, so that the highest content of chlorophyll a (25.75 µg/ml) was recorded in Long Island × T. harzianum cultivar treatment. Long Island × T. harzianum treatment had the highest total chlorophyll content (30.61µg/ml) and local cultivar of Tabriz × R. irregularis (16.56µg/ml) had lowest. The highest (9.64µg/ml) and the lowest (3.57 µg/ml) amount of carotenoids was observed in Long Island × T. longibrachiatum and local cultivar of Tabriz × T. harzianum treatments, respectively. Long Island × T. longibrachiatum cultivar and local cultivar Tabriz × control treatments with 0.6 and 0.2 ml/g produced the highest and the lowest essential oil yield.

Journal Article 2021 02 24 In order to investigate the quantitative and qualitative response of three sesame cultivars (Sesamum indicum L.) to different irrigation and fertilizer treatments, an experiment was conducted in the research farm of Seed and Plant Improvement Institute, Karaj, during 2016 and 2017. The experiment was performed as split-factorial plots in a randomized complete block design with three replications. Irrigation treatments at two levels (low and full irrigation) were the main plots and factorial plots with different amounts of nitrogen and sesame cultivars were the subplots. The results showed that in full irrigation conditions, application of 120 kg N ha-1 increased sesame seed yield by 83% compared to non-application. In contrast, this increase in yield in response to the application of nitrogen in low irrigation treatment was 40%. The results also showed that the highest water use efficiency in full and low irrigations was obtained from Oltan and Dashtestan 2 cultivars with 120 kg N ha-1, respectively. Dashtestan 2 cultivar had the highest (51%) and Naz single-branched cultivar had the lowest (47%) oil content. In general, the results showed that in full irrigation treatment, nitrogen fertilizer application for all three cultivars can be justified; In contrast, in low irrigation conditions and none of the cultivars, grain yield higher than 500 kg N ha-1 was not achieved even with high amounts of nitrogen (60 and 120 kg N ha-1).

The objective of this study was to evaluate the remobilization potential of wheat varieties by potassium iodide. 22 wheat cultivars as sub plots were cultivated in a split plot design with three replications in two growing seasons 2015- 2017 and application and no application of potassium iodide (KI) were main plots. Yield, the number of seed per spike, remobilization, and contribution of remobilization in grain yield were estimated. Significant genotypic variation among cultivars was observed under both normal and KI application. Current photosynthesis elimination decreased the average seed weight per spike by 46%. Grain yield per spike in some cultivars such as Shoosh, Pishgam and Arta and Zare was decresed significantly (up to 65%). The average of grain number per spike was 38 in control, but the application of potassium iodide reduced it to 24% (29 grain per spike). The results of this study showed that the inhibition of current photosynthesis increased the remobilization of assimilate from 3% to 44% in different cultivars. According to the results of cluster analysis, Karim, Shebrang, Hamoon, Pishgam and Dena cultivars had high and also Zare, Chamran and Shush cultivars had low remobilization potentials.
