Biplot Trait Analysis of Some of Canola (Brassica napus L.) Genotypes in Irrigation and Drought Stress Conditions
Canola is an important industrial plant in oil production, and in recent years, it has drawn a lot of alteration due to its adaptation to the arid regions. To determine the relationship between these traits and traits relevant to yield at both normal irrigation and drought stress condition and To evaluate the effect of water deficient on canola genotypes at vegetative and generative stages, the experiment was conducted in the research farm Institute of Plant Breeding of Karaj using randomized complete block design with four replications on 25 genotypes under two normal irrigation and drought stress conditions. The data were analyzed by biplot and path analysis methods. Correlation coefficients between yield and other characteristics were calculated and a high significant relationship with yield component was observed. Path analysis in both normal irrigation and drought stress conditions showed that harvest index and biological yield traits had high direct effects on seed yield and these traits can be introduced as the most important traits of effective yield and used as the selection criteria for grain yield for reformation in canola. A positive and significant correlation was observed between seed yield and the number of seeds in main pod, and also the number of seeds in branch pod and the number of seed in pod. In order to study interrelationships between traits and facilitate visual comparison of genotypes, treatment biplot method was exploited. In the normal irrigation condition, genotypes Jura, Elvis, Eshydromel, GKH305 and Vectra, and at drought stress condition, genotypes Jura, Eshydromel, GKH305 and GKH1103 were introduced as superior genotypes because they have favorable traits such as high seed yield, number of seeds in main pod, number of seeds in branch pod and number of seeds in pod.

Crop Loss Assessment and Canola (Brassica napus L.) Impact Factor Analysis in late Planting
Factors such as unprepared seed bed and agronomical elements or local common rotation are usually the cause of conola late planting. This experiment was counducted as randomized complete block desing with four replications in two years 2005-2006 and 2006-2007 . Seven planting dates, begining from Nov 6th to late Dec 18th with one week interval, were determined in Ahvaz Agricultural Research to assess canola hybrid Hyola308 crop loss and analyze yield impact factors in late planting. Results showed that the delay in canola planting caused a significant effect on the increase of the interval between planting and emergence, reduction seed emergence percent, flowering and maturity duration. Reduction in reproductive length led to a significant loss in pod per plant, seed per pod, and thousands seed weight. Each day delay to a reduction of seed and oil by 2.6 percent. Traits and yield component correlations, direct and indirect effect path analysis showed that flowering initiation had the most direct and indirect effects via other factors on seed and oil yield, so the sowing date must be regulated in such a way that flowering initiation happens with optimum condition (Feb 3th), and with 14-17C environemtal temperature.

Evaluation of Morphological Traits, Yield and Yield Component of Three Plantago Species Under Salinity Stress
In order to study the salinity effect on morphological traits, yield and yield components of Isabgul (Plantago ovata), French psyllium (P. psyllium) and Great plantain (P. Major), an experiment was conducted at Vali-e-Asr University of Rafsanjan in 2010. The study was carried out as factorial experiment based on RCBD design with 4 replications to determine the influence of salinity (9, 15, 21 ds/m and control with distilled water) and three plantago species (Isabgul, French psyllium, Great plantain). Results indicated that plant height, leaf area, root and shoot dry matter, yield and yield components were decreased significantly (P<0.05) with increasing salinity levels. However, the reduction trend was different among species. Seed yield of Isabgul, French psyllium and Great plantain decreased in 15 ds/m salinity by 44, 79 and 77 percent in compaison with control, respectively. Contrary to Great plantain, the thousand seed weight decreased in 15 ds/m salinity by 38 and 35 percent in Isabgul and French psyllium compared with control, respectively. Salinity did not affect specific leaf area (SLA) in all species. In general, among the three species, Great plantain, with higher dry matter and seed yield, was recognized as a species that is more suitable to be cultivated in saline areas.

In order to study the effects foliar application of Zn and Mn of deficit irrigation at vegetative and reproductive growth stages of two corn cultivars, including SC-301 and SC-400, an experiment was conducted during the 2008 growing season at Experimental Field of the Agricultural Faculty of Buali-Sina University. The experiment was a factorial split plot arrangement on the basis of randomized complete block design with three replications. The irrigation levels were full irrigation, deficit irrigation stress at 8-10 leaf stages and milk till dough ripening stages of grain. Foliar applications were without foliar application, foliar application of Zn and foliar application of Mn. Two corn cultivars (SC-301 and SC-400) were allocated to subplots. Growth degree day until flowering, number of kernel per ear, kernel weight, biological yield, economical yield, harvest index, grain filling period, water use efficiency, and grain protein content were measured and calculated. Effects of drought stress, foliar application and cultivars on trentments the mentioned were significant. Water deficit stress at 8-10 leaf stages and without foliar application had the most negation effect on growth degree day until flowering, grain filling period, number of kernel per ear and economical yield in this study. The highest value of the mentioned treatments was reached for foliar application zn and full irrigation. The most water use efficiency, 1.44 kg/m3, was obtained with water deficit stress at the reproductive stage and the least value, 1.21 kg/m3, was obtained with water deficit stress at the vegetative stage. The Most grain protein content, about 9.8 percent, was obtained with ZN foliar application and water deficit stress at the reproductive stage.

Effect of Integrated Weed Management Systems on Yield Quality and Quantity of Sugarcane in Khouzestan
In order to evaluate the effect of integrated weed management on the yield quality and quantity of Sugarcane, variety CP69, a field experiment was conducted during 2009-2010 at the Argo-Industrial farm of Deabel-e-Khozaie located on the Southeast of Ahvaz. The research was a randomized complete block design (RCBD) with 3 replications, including 9 diferent control mathods in three groups (i.e. Chemical, Agronomical and Integrated) with three replications. The control methods were 1: the combination of Atrazin and Ametrin+2.4D by the ratio of 5kg and 2.5kg + 2litre; 2: The combination of E.P.T.C +Metribuzin by the ratio of 8litre +2kg. 3: The combination of Tebuteyouran + Atrazin and Ametrin + metribuzin by the ratio of 2liter + 2kg and 3kg + 2kg in the hectar, respectively (Chemical Control). 4: only Sugarcane leaves; 5: only cultivation; 6: The combination of Bagas and mud (Agronomical). 7: The integration of Atrazin and Sugarcane leaves. 8: The combination of E.P.T.C and cultivation; 9 The combination of Tebuteyouran + Atrazin by the ratio of 2liter + 2kg and mud + bagas, respectively (integrated methods). The yield quality and quantity and yield components of Sugarcane and the weed's status were calculated. Results showed that the highest Cane's diameter, weight of main stem, cane yield and sugar yield were obtained in integrated method, treatment No. 8 (including herbicide & cultivation). Also, the best sugar quality including sugar purity and polarity was obtained in this treatment (i.e. method No. 8). Inaddition, based on these results we found that integrated approches had a higher quality and quentity for sugarcane yield compared to other methods (i.e. chemical & agronomical methods). Therefore, for ideal weed management and reduction of herbicide use, the integrated herbicide with interrow cultivation was the best weed management method in sugarcane.

Effect of Different Planting Patterns on LER, Yield and Yield Components of Peanut and Two Corn Hybrids in Intercropping System
Mixed cropping is one of the most important principles of sustainable and organic agriculture. Intercropping of peanut (Arachis hypogaea L.) and corn (Zea mays L.) is the most successful mixed cropping in north areas of Iran. Nevertheless, in this region, there has hardly been any research to determine the best sowing pattern and varieties of corn that could be cultivated with peanut. Thus, an experiment was conducted to evaluate three planting patterns and two varieties of corn and their interaction effects on LER, yield and yield components of peanut and corn varieties. A complete randomized design (CRD) was conducted in three replications, factorially in a rain fed farm of Lahijan in summer of 2005. The varieties consisted of two levels of early and late mature hybrids of corn (KSC301 and KSC 704). The planting pattern consisted of tree levels including one row of corn and tree rows of peanut, one row of corn and five rows of peanut and two rows of corn and five rows of peanut. Agronomic practices were done based on peanut requirements, because peanut is cash crop and more important than corn for farmers in this region. Results of this experiment showed that hybrids and planting pattern have significant effects on LER and the yield of peanut. In sum, one row of late mature corn (KSC704) and five rows of peanut were best in LER (1.15). KSC 704 variety resulted in higher yield of peanut than early matured corn (KSC301), because this cultivar had different canopy with peanut and interfere into the growth of peanut less than the other.

Investigation of Hinokitiol, PBA, ABA, NAA and TDZ Effects on In-vitro Regeneration of Alstroemeria by Using of Rhizome Explants
Alstroemeria is one of the most popular and attractive cut flowers. Recently, its production has considerably increased in our country. Alstroemeria is generally reproduced by rhizome splitting. But the rate of reproduction is very low. This experiment was conducted in completely randomized design wiht 16 treatments and 5 replications in tissue culture and biotechnology laboratory of Mohaghegh Ardabili University in 2010. For this purpose, rhizome explants were cultured on MS medium supplemented by different concentrations of NAA, ABA, TDZ, PBA, Hinokitiol and control (MS medium without plant regulators). The results revealed that NAA at 4 mgl-1 and Hinokitiol at 1 mgl-1 produced the highest rhizome number compared to control. In this experiment, prepared medium containing Hinikitiol at 10 mgl-1 and PBA at 1 and 4 µM did not produce any rhizome. MS media with Hinikitiol at 1 mgl-1 produced the highest rhizome length (3.58 cm) compared to control and other treatments. The highest (8.99) and lowest (0.56) leaf numbers were produced by media containing TDZ at 2µM and NAA at 4 mgl-1 respectively. However, the highest and lowest leaf losses were observed by Hinikitiol in media containing 1 mgl-1 and NAA at 1 mgl-1 respectively. No significant differences were found in case of stem and root length and number.

Effects of Postharvest Chitosan Treatment on of Fungal Growth and Quality of Rishbaba Table Grape During Cold Storage (Vitis vinifera L. cv. Rishbaba)
A study was carried out to determine the effects at postharvest chitosan treatment on the pattern of quality changes in red Rishbaba table grape. The bunches were treated with chitosan at 0, 0.5 or 1% concentration and stored at 0±0.5°c for 4 months. Fruit quality attributes including total soluble solids, total acidity, ascorbic acid content, decay incidence and bunch browning, berry browning, berry abscission, taste and flavor were evaluated after 2 and 4 months during storage. After 2 months of cold storage, the fruit treated with 0.5% chitosan had the highest ascorbic acid and lowest level of berry browning and abscission. At the end of storage period (4 months), bunch browning was low at 0.5% chitosan treatment. Taste and flavor at the end of 2 months with 0.5% chitosan and at the end of 2 and 4 months with 1% chitosan were high compared with control. TSS and fungal decay contents were not significant. According to the obtained results, treatment with 0.5% chitosan showed the best effect on quality of Rishbaba grape.

Effect of Ion Combination Variation on Physiological Characteristics in Two Genotypes of Canola (Brassica napus L.)
In order to study the effect of ion combination variation on physiological characteristics of two genotypes of canola (Brassica napus L.), a pot experiment was carried out. The experimental design was strip split plot in completely randomized design with three replications. The main factors included of three levels of salinity (control, 8 and 14 dS/m) and ion combination with two levels (NaCl & Na2So4) and the second factor was genotype with two levels (Hayola 401 & RGS000). The measured parameters were fresh weight, LA, SPAD, stomata conductance, RWC and osmotic potential. Results showed that in genotype (Hayola 401 & RGS000), fresh weight, LA, stomata conductance, osmotic potential and RWC significantly decreased by increasing salinity. But by moving from the control level to 8 dS/m the SPAD value increased, while it decreased in 14 dS/m. In NaCl and Na2So4 there was a significant effect to decrease fresh weight, LA and osmotic potential in both genotypes. Also the effect of ion combination on the SPAD value had no significant differences. The most significant effect to decrease the value of stomata conductance was showed by Na2So4. The height fresh and the lowest fresh weight were 10.88 g/plant (in Hayola 401 in control treatment) and 3.60 g/plant (in 14 dS/m of NaCl treatment). The maximum leaf area showed in Hayola 401 (LA=41.2 cm2) in the control treatment and the minimum (LA=16 cm2) was in RGS000 genotype in 14 dS/m which was made by NaCl. Hayola 401 reached the highest stomata conductance (0.26 mol/m2/sec) in control treatment and RGS000 showed the minimum stomata conductance (0.06 mol/m2/sec) in 14 dS/m which was exposed by Na2So4. Although leaf area, stomata conductance, osmotic potential and leaf relative water content were reduced in both genotypes by increasing salinity, this reduction was higher by NaCl.

Effect of Nutrient Solution Culture on Stomatal Response to Drought Stress in Tradescantia virginiana Grown Under High Relative Air Humidity
In this research, we aimed to elucidate the effect of nutrient solution culture on stomatal response to drought stress in high relative air humidity (RH) grown plants using the new method of chlorophyll fluorescence measurement under low oxygen concentration. According to the results, stomata of high RH grown plants failed to close fully in response to drought stress. However, growing plants in nutrient solution under high RH produced stomata which closed quickly in response to drought stress. Moreover, stomata of plants grown with a split root system in soil and nutrient solution under high RH closed quickly in response to drought stress. Removing roots from nutrient solution in plants grown with a split root system resulted in diminished closure of stomata in response to drought stress. Evidently, some as yet unidentified positive signals produced by roots growing in nutrient solution, transferred to leaves and resulted in the production of efficient stomata.
