1 - Biodiversity in qualitative and quantitative traits of Iranian fenugreek landraces in Hashtrood region, Iran
Bahram Hajizadeh Davoud Sadeghzadeh-Ahari Soleiman JamshidiTo determine some qualitative and quantitative traits diversity of five Iranian fenugreek landrace including Kermanshah, Semnan, Khash, Borazjan and Ardestan landraces, An experiment was carried out based on randomized complete block design in four replications at MoreTo determine some qualitative and quantitative traits diversity of five Iranian fenugreek landrace including Kermanshah, Semnan, Khash, Borazjan and Ardestan landraces, An experiment was carried out based on randomized complete block design in four replications at Hashtrood region in East Azarbaijan province, Iran during 2011- 2012 cropping season. Based on results, there were significant differences among the landraces in qualitative and quantitative traits including days to flowering and maturity, plant height, height of the first pod from soil level, no. of pod and branches, thousand kernel weight, fresh and dry biomass, grain yield, crude protein percentage, dry matter digestibility, water soluble carbohydrates percentage, neutral detergent fiber and total ash. The highest fresh biomass and grain yield belonged to the Ardestan landrace. Comparing with other landraces, Borazjan had better forage quality because of the highest dry matter digestibility and water soluble carbohydrates percentage, and the lowest levels of cell wall without hemicelluloses. Considering diversity among the studied fenugreek landraces in qualitative and quantitative traits, protection and implementation of them in breeding programs to generate cultivars with desirable agronomic traits, high yielding and production of forage with suitable quality are recommended.

Woundwortsamples were collected from three habitats including Erelan, Golajar and Nojehdeh Sheikhlar located in Marand, Iran in late spring and their geographical characteristics were recorded. Some morphological and physiological traits such as stem length, plant fresh and dry weight, chlorophyll a,b and total chlorophull content, and biochemical characteristics including Na, K, Ca, Mg and P content and also yield and essential oils yield and composition were measured. Obtained data were analyzed based on completely randomized design. The amount of Mg in Goljar, stem length in Nojedeh Sheikhlar, Na and fresh weight and chlorophyll a and b content in Erlan were in maximum value. Anti-oxidan activity was the same in all habitats. Wounworts collected from Erlanhad more Na content comparing other habitats which can be related to higher germacren D in plant tissues collected from this region. Manuscript profile -

Drought is a natural and recurrent climatic feature in most parts of the world and plays an important and limiting role in crop yields. In this study, to ensure the stress on the medicinal herb of coneflower (Echinacea purpurea), the proline, potassium, phosphorus and nitrogen content of the leaves were evaluated in a completely randomized design with three replications, each of which was repeated in three pots. Also, expression of heat shock proteins in leaf tissue under four levels of drought stress irrigation at 25%, 50%, 75% and 85% of crop capacity was evaluated. The results showed a significant increase in the amount of proline, potassium, phosphorus and nitrogen in leaf tissue. Also, examination of thermal shock protein expression using Real-Time PCR indicated that drought stress significantly increased expression of heat shock protein in all studied treatments, which also proved the changes caused by stress. In general, the coneflower plant resists some degree of resistance using of some protective mechanisms, such as increasing proline and heat shock proteins content. Manuscript profile -

On the other hand, salicylic acid is effective as a plant growth regulator on inducing mechanisms in plant resistance enhancment against biotic and abiotic stresses. Apot experiment was conducted as factorial based on completely randomized design to evaluate the effect of salicylic acid on improving morpho-physiological indices of basil under salt stress. Seedlings with six to eight leaves were sprayed by salicylic acid at concentrations of 0.1, 0.5 and 1 mM before salinity stress application and continued for three weeks. The salinity stresses were applied by irrigation of plants with saline solutions at concentrations of 20, 40 and 80 mM of sodium chloride. At flowering stage, plant height, stem diameter, leaf length and width, leaf and inflorescence number, leaf, stem, and root fresh and dry weight, the longest inflorescence and root and internode length, stem node number, leaf, stemç and root dry weight percentage, leaf electrolyte leakage, relative humidity, leaf chlorophyll index, leaf area indexç and special leaf area were measured. Salinity stress reduced leaf length and width, leaf area index, branch nodes number, stem diameter, root fresh and dry weight, stem dry weight, special leaf area and increased leaf electrolyte leakage and leaf number. In contrast, using salicylic acid was effective in reducing of the adverse impacts of salinity stress in most of the traits. Also, salicylic acid spraying had more compensatory effect on salinity stress at concentrations of 0.1 and 0.5 mM. Therefore, salicylic acid spraying can be recommended as a contsructive approach to prevent adverse impacts in basil under salinity stress conditions. Manuscript profile -

Gohar, an experiment was conducted in factorial based on randomized complete block design with three replications in Khorramabad region. The examined treatments included application of cow manure at three levels of control, 10 and 20 t/ha added to soil before planting, and seed inoculation with bio-fertilizers of nitroxin and biosuperphosphate in the rate of 1 L/10 kg of seed, applied separately and in combination with each other. The effect of manure on grain and biological yield, harvest index, and interaction of manure and biological fertilizers had significant effect on the number of pods per plant, number of seeds per pod, number of seeds per plant, thousand kernel weight, grain and biological yield and harvest index. Combination of biofertilizers with cow manure increased soil elements amount and improved growth and development of photosynthetic organs and resulted in yield and yield components increment in mung bean. Therefore, application of biological fertilizers combined with 20 ton/ha cow manure is recommended for achieving desirable mung bean yield in Khorramabad region. Manuscript profile -

Plant growth promoting bacteria can be used as a biological solution to mitigate negative effects of drought stress. To investigate the effect of seed priming with growth promoting bacteria on yield and yield components of corn SC770 under different drought stress conditions, a split-factorial experiment based on randomized complete block design was conducted at Kermanshah Research Center during growing season of 2017-2018. Four irrigation levels including normal irrigation, very mild, mild, and severe stress were applied by implementing of single-branch irrigation system. The seeds are inoculated by Pseudomonas putida Strain 41, 159 and Pseudomonas fluorescence Strain 23. Bacterial inoculation had significant impact on all studied traits. Increasing stress level depressed all studied traits compared to normal irrigation condition. Also, at all stress levels, bacterial inoculation improved corn traits. Therefore, seed priming with growth-promoting bacteria especially P. putida Strain 159 is recommended for improving yield and plant drought tolerance. Manuscript profile
