Study of morphological traits of red fleshed apples is a critical step to improve the quality andcommercializing of them. In order to study genetic diversity of Iranian red fleshed apples, a total of 17morphological characteristics were assessed for eight genotypes of red- fleshed (‘Haji Qermez’, ‘GoushtQermez’, ‘Shahroud-10’, ‘Arous Gousht Qermz’, ‘B.9’, ‘Qazvin 1, 2, 3’) and 12 Iranian and foreigncommercial cultivars (‘Shafei’, ‘Golab Kohanz’, ‘Jonathan’, ‘Golden Delicious’, ‘Granny Smith’,‘Soltani Shabestar’, ‘Fuji’, ‘Red Delicious’, ‘Heydar Zadeh’, ‘Golab Sahneh’, ‘Gala’, and ‘Shafi Abadi’).Dendrogram resulting cluster analysis of the data classified all genotypes into 7 groups. All Iranian andforeign cultivars were located in distinct groups. The results showed that Iranian red fleshed apples weredifferent in their flesh color. This research can be very useful for introducing theses cultivars to market orusing in breeding programs.

To investigate the effects of deficit irrigation and different levels of nitrogen fertilizer on somequantitative and qualitative properties of Melissa, a pot experiment was conducted for one year (2011) inMazandaran province. Experiment was carried out as a factorial based on randomized complete blockdesign with three replications. Irrigation treatments (25, 52 and 75 percent field capacity, FC) andnitrogen fertilizer (0 and 2.5 percent ammonium nitrate) were allocated to main and sub-plots,respectively. The results showed that the effect of different levels of deficit irrigation were significant onquantitative and qualitative properties of Melissa. Fertilizer treatments were significant on dry weight,leaf area, shoot number and fresh weight, percent citronellal, caryophyllene oxide percent, geranial andneral percent. Interaction of treatments was significant only on leaf number, dry weight of shoot, freshweight of plant and geranial percent. Results showed that maximum plant height, leaf area, number ofstems, number of leaves and dry and fresh weight was obtained in 75 percent FC treatment. Percent ofcitronellal, caryophyllene oxide, geranial and neral with 6.14 percent, 11.61 percent, 20.09 percent and17.38 percent, respectively, had a maximum amounts in 75 percent FC treatment. Also, application ofnitrogen fertilizer caused 5.33 and 9.15 percent reduction of citronellal and caryophyllene oxiderespectively and increased geranial and neral percent by 17.64 and 15.56, respectively.

To evaluate the effects of water deficit stress in barley germplasm collection of National Gene Bank ofIran, 25 genotypes collected from arid and semi arid provinces of Iran and 3 sample cultivars werestudied in two environments including: non-stressed and water deficit stress. Agronomical, phenologicaland morphological traits were measured. Stress indices were calculated to determine tolerant genotypes.Based on correlation coeficiences, STI were better indicator of drought stress tolerance than the otherindices. Based on STI, morphotypes number 16, 24, 25 and 26 shown better stress tolerance potential thanthe other morphotypes. Stepwise regression between stress tolerance index (STI) and quantitave traitsindicates the important role of leaf area and specific leaf area of flag leaf under drought stress condition,in acclimation to drought conditions. It is also concluded that the 100 grain weight is the only trait undernormal condition witch shows a close relation with stress tolerance index.

In order to assess the impact of different sowing dates on yield and yield components of wheat genotypeswith different growth habits, a two years study (2007-2009) using a split plot in randomized completeblock design with three replications was conducted in Kabootarabad Agricultural Research Station ofIsfahan. Three sowing dates of 12 Oct., 1 Nov., and 21 Nov. were main plots and 15 genotypes of wheatwere subplots. The average grain yield in three planting dates was 8495, 9156 and 6749 kg ha-1,respectively. At all planting dates, the maximum and minimum grain yield belonged to spring and wintertypes and the grain yield of winter, facultative and spring groups were 7519, 8267 and 8614 kg ha-1,respectively. At 1 Nov. five spring genotypes M-81-13, Bahar, Pishtaz, Kavir and Marvdasht andfacultative cultivar Alvand produced the highest grain yield by an average of 10433, 10146, 10040, 9843,9822 and 9813 kg/ha and therefore can be recommended for planting in temperate regions of theprovince. Spikes per m2 and grain weight were the most important yield components that were reduced inresponse to late planting. Based on the results, 1 Nov. can be recommended as the best planting date forthe region.

In order to investigate the effects of boron, zinc and sulfur on yield and fatty acid composition of rapeseed(Hyola 401 cultivar), an experiment was conducted in Rasht province in 2011. A field experiment withcompletely randomized block design was performed with eight treatments in three replications.Maximum grain yield (4157.6 kg ha-1) and grain oil (1770.2 kg ha-1) was obtained from S+B+Zntreatments. The highest and lowest grain oil was obtained from S+B+Zn (42.58) and control (38.37),respectively. The maximum oleic acid (234.8 mg g-1) and linolenic acid (26.68 mg g-1) and linoleic acid(55.98 mg g-1) were obtained from B+Zn+S treatments. Maximum stearic and palmitic acid were obtainedfrom control and S+Zn treatments which was 6.5 and 15.53 mg g-1, respectively. Regarding to the results,fatty acids composition of rapeseed are influenced by nutrient and since quality of edible oils depends onunsaturated fatty acids, especially linoleic and linolenic acids and these acids are essential fatty acids forthe human body that must be supplied through diet. Therefor this research showed that we are not onlyable to increase oil yield with can also increase oil quality with increasing fatty acid composition.

In order to study the reaction of barley genotypes to drought, an experiment was conducted in a factorialdesign based on CRD for two wild ecotypes and four crop genotypes of barley in greenhouse. In thisstudy, the barley genotypes and wild ecotypes as the first factor and irrigation treatment with three levelsinclude 70 percent of water holding capacity of soil, 30 and 10 percent as the second factor wereconsidered as treatments. Analysis of growth and other morphological characteristics such as tillers, plantheight and leaf number and leaf area per plant and some physiological characteristics including therelative water content, leaf chlorophyll content, osmotic potential, osmotic adjustment, stomatalconductance, canopy temperature in each three treatments were measured. Analysis of variance showedthat the effect of drought on all traits and differences between genotypes were significant. Results ofcorrelation revealed that there is a significant and direct relationship between relative water content withosmotic potential and percentage of dried material. Path analysis identified that osmotic potential had themost direct effect on died material. The 41-1 and Morocco genotypes showed greater sensitivity thanother genotypes to the applied stress.

To evaluate the competition effect of velvetleaf on cotton, an experiment was conducted in a completelyrandomized block design with split plot arrangement of treatments with three replications at ExperimentalStation of Gorgan University of Agricultural Sciences and Natural Resources during 2011 growingseason. The treatments were three row spacing (20, 40 and 80cm) of cotton (as main plot) and fivedensities (0 (control), 1, 3, 5 and 12 plant per m-2) of velvetleaf (as subplot). The highest cotton height(129.4 cm) was obtained in 80 cm cotton row spacing and weed free condition. Also, maximum cottondry matter (863.8 g m-2) and leaf area index (9.04) was achieved in the plot of 20cm cotton row spacingand weed free condition. Results indicated that row spacing had no significant effect on cotton yieldunder weed free condition. The highest yield (4986.73 kg ha-1) was obtained in 40 cm cotton row spacingand weed free condition. However, results showed that in ultra narrow row, increasing the plant densitylead to increase of the crop ability to resource using in compared with weed and have producedsustainable yield in competition with over weed density in compared with conventional row.

In order to study the effect of different concentrations of salicylic acid in two commercial apricotcultivars of Shahrood namely ‘Shahrood 41’ and ‘Jaffari’, under cold stress, a factorial experiment wasconducted in a randomized complete block design with three replications in 2012 at the AgriculturalResearch Center of Shahrood city. The test had four factors including: SA with three levels (0.625, 0.125,0.25mM), three stages of phenological growth (dormancy, swelling and flowering) and four temperature(four, zero, -2 and -4 degree centigrade) and two apricot cultivars (‘Shahrood 41’ and ‘Jaffari’) andmeasured traits were proline and soluble sugars. ‘Jaffari’ cultivar had the highest amount of solublesugars at -4 degree centigrade in bud swelling stage and the maximum rate of proline belonged to0.25mM of SA in the same cultivar, -4 degree centigrade and bud swelling stage. Ion leakage at differenttemperatures and different phonological growth stages were significantly different at five percent level.‘Jaffari’ with lower ion leakage at -4 degree and higher proline content than ‘Shahrood 41’ had higherresistance to frost.

In order to study of nitrogen application time and seed inoculation with plant growth promotingrhizobacteria on yield, fertilizer use efficiency and grain filling rate of sunflower, a factorial experimentwas conducted based on randomized complete block design with three replications in research farm ofIslamic Azad University, Ardabil branch in 2011. The first factor was time of nitrogen application inthree levels, (1/3 at 4-6 leaf stage, 1/3 at budding stage, 1/3 at flowering stage), (1/2 at 4-6 leaf stage, 1/2at budding stage), (1/4 at 4-6 leaf stage, 1/2 at budding stage, 1/4 at flowering stage) as N1, N2 and N3respectively and the second factor was seed inoculation with plant growth promoting rhizobacteria in fourlevels containing (without inoculation as control, seed inoculation with Azotobacter chrocococum strain5, Psedomunas putida strain 9, Psedomunas putida strain 41). The results showed that maximum of grainweight, grain filling period, grain and biological yield, 1000 grain weight, number of grain per head, plantheight, head and stem diameter were obtained in nitrogen application as N2×seed inoculation withAzotobacter. Maximum of nitrogen use efficiency was recorded at nitrogen application as N2×seedinoculation with Azotobacter and minimum of it was obtained in nitrogen application as N1× no seedinoculation. It seems that in order to increasing of grain yield, fertilizer use efficiency and grain fillingrate, can be suggested that should be applied nitrogen application time as N2×seed inoculation withAzotobacter.

To evaluate the effect of limited application of nitrogen (N) on the height control of geranium(Pelargonium hortorum) and improving its quality performance, an experiment was conducted based on acomplete randomized block design with three replications in the greenhouse environment through theyears 2011-2012. Geranium seedlings were cultivated in the pots filled with peat-based substrate (peat, 80vol. percent + sandy loam field soil 20 vol. percent). For the limited application of N, four differentnutrient solutions with the same macro and micro elements, except N levels of 2.5, two, 1.5 and one mMwere applied. The rate of ammonium to nitrate nitrogen for all treatments was kept as 20 to 80 percent.The traits such as plant height, number and length of shoots, number of florescence and number offlowers in the florescence, pedicle length and leaf number, leaf area, chlorophyll, antocianins, fresh anddry weight of shoot and root were measured at the end of the experiment. Limitation of N applicationfrom 2.5 mM to 1.5 mM in the nutrient solution, although reduced the length of shoot, but did not affectnegatively the quality of plants. Farther decreasing of N level to 1 mM, negatively influenced the allquality and quantity parameters of the plant and may not be introduced for production of geranium.

The effect of Kaolin on fruit and oil of olive cv. `Zard’ was evaluated in a commercial orchard in Fasacity, Fars Province. Mature olive trees cv. `Zard’ were sprayed with 0, 3 and 6% kaolin after 60 days, 60and 90 days and 60, 90, 120 days after full bloom. Results showed that kaolin concentration and sprayingtime had not significant effects on physicochemical parameters but they had significant effects on freefatty acids composition. linoleic acid (14.49 percent) and linolenic acid (1.02%) were lowest in the thirdlevel of spraying time. Amount of oleic acid, monounsaturated fatty acids to polyunsaturated fatty acids,oleic acid to linoleic acid were higher in oil extracted from trees treated with 3 or 6% kaolin than theuntreated trees. Also, oleic acid to linoleic acid (4.65%), monounsaturated fatty acids to polyunsaturatedfatty acids (4.2%) were the highest in 6% kaolin with thrice spraying treatment (6% kaolin × thricespraying) while linolenic acid, palmitic acid, linoleic acid were the lowest in 6% kaolin × thrice spraying.Therefore this study showed fatty acids composition was improved by kaolin spraying.

German chamomile (Matricaria chamomilla) is one of the most important industrial medicinal plant. Inthis experiment the effects of foliar application of salicylic acid in different levels (0, 10-2, 10-4, 10-6) wereinvestigated on the floral traits and essential oil content of three ecotypes (Italian, Tehran, Zabol) ofGerman chamomile. The results showed that maximum percentage of essential oil (1.5 weight percent)was obtained from Zabol ecotype as sprayed with 10-4 M of salicylic acid and Maximum oil yield (0.085gr per pot) was obtained from Italy ecotype in which treated with 10-2 M salicylic acid. Among theidentified sesquiterpenes of essential oil, Chamazulene, E-β Farencene and α-Bisabolol oxide A weresignificantly varied based on the experimental treatments. The highest amount of Chamazulene (3.789percent) was recorded in Italian ecotype in which treated with 10-2 M salicylic acid, and the same ecotypeproduced highest amount of farencene (2.264 percent) when treated with 10-2 M Salicylic acid. Theapplication of salicylic acid in concentrations of 10-4 and 10-6 M increased the α-Bisabolol oxide A(respectively, 70.907 and 73.482 percent) Compare with control. Generally, contrary to essential oil yieldcomponent, only the essential oil yield and its constituent were affected by salicylic acid application andthe responses of experimental ecotypes was varied.

In order to assess soybean, sweet basil and borage yield intercropping system, an experiment wasconducted based on randomized complete blocks design with 9 treatments and three replicates in 2011.Treatments were consisted of replacement ratios of 75: 25, 50: 50, 25: 75 soybean: sweet basil and borageand pure culture of each plant. The results showed that the first pod in 75: 25 soybean: borage and solecropping of soybean observed to be positioned at upper height than other treatments. The node number ofstem was more in intercropping treatments than sole crop. In intercropping treatments, the pod numberper plant except 25: 75 soybean: borage and seed number per plant except 25: 75 and 50: 50 soybean:borage was higher than sole crop. Seed yield and biological yield was decreased by increasing sweet basiland borage proportions in intercrop except 75: 25 soybean: sweet basil. The seed yield and dry weight ofplant of intercropping was higher than pure culture of soybean. Yield of sweet basil in both growth periodand also seed yield of borage was decreased through increasing soybean presence. Area-time equivalentratio indicated 9, 11 and 14 percent advantages of the 75: 25 soybean and sweet basil and borage ratio and50: 50 soybean and borage compared to monoculture, respectively.
