The Effect of Different Sources of Calcium on the Some of Quantitative and Qualitative Parameters of Tea Plants (Camellia sinensis L.)
Soil pH is one of the important chemical characteristics of soil that plays major role in growing of tea plant and affects on absorbing of food elements by plant and their usability. In this study, the effect of different calcium source was investigated on some of quantifying parameters in tea plant, pH and EC in tea soil. Tea is plant with shallow roots, this shrubs grows two forms wild and farmed. The leaves of plant are the use in tea that is important economically. This study was conducted as a factorial with two factors, calcium fertilizer type and fertilizer levels on the basis Completely Randomized Design (CRD) with three replications. In order to supervise content of calcium component which contains calcium carbonate, dolomite, calcium oxide and calcium chloride with four levels (0, 1, 2, 3) g ca / kg was added to soil with three replications. The result of analysis of variance related to calcium fertilizer on soil pH indicated that only calcium fertilizer type in soil pH is significant at 0.1%. Also the result of calcium fertilizer on soil EC showed that the type of calicum fertilizer, fertilizer level and interaction effects and level of fertilizer on soil EC is significant at 0.1%. But the effect of different sources of calcium has not significantly different on parameters of quantity in tea plant during investigation (three months).

Effect of Nitrogen, Manure, Potassium and Iron on Yield, Fruit Quality and Leaf Mineral Nutrient Content in Pistacia vera cv. Fandoghi Grafted on Badami-Riz Zarand Rootstock
This research carried out in the Rafsanjan pistachio orchard to investigate the effect of N form, manure, K and Fe on yield, nut quality and leaf mineral nutrients concentrations of Pistacia vera L. cv. Fandoghi grafted on Badami-Riz Zarand rootstock. The experiment was as factorial with four factors including; manure (without manure and 10 kg tree-1 sheep manure), N form (ammonium sulfate and calcium nitrate), K (without K and 600 kg K tree-1) and Fe (without Fe and 100 g Fe tree-1) and randomized complete blocks design with 6 replications. Fertilizers were added to the soil in holes with 40-60 cm depth on two sides of trees, and treatments effects was evaluated during two years. The results showed that ammonium application increased the nut yield compared to nitrate fertilizer, this increase in yield is may related to the higher N and Fe in plants and consequently leaf chlorosis alleviation due to the chlorophyll contents elevation by these elements. Combination of ammonium-N and Fe increased split pistachio nuts. In this research, ammonium application increased the concentration of Fe, Zn, N and K and reduced P, Ca and Mg concentrations in leaves. Therefore, it is suggested to use N fertilizer containing ammonium rather than nitrate in pistachio orchards with mainly high soil pH.

Effects of Sterilization Protocol and Pre-chilling Treatment on In vitro Seed Germination of Levisticum officinale Koch.
To protect and multiply important and rare plant resources, in vitro culture serves as a more efficient alternative to traditional propagation approaches. Levisticum officinale Koch. a member of Apiaceae is an important, endangered and neglected species in Iran, which has been shown to have diuretic, spasmolytic and carminative effects. In order to supply enough plant materials for micro-propagation of this herb and study effects of different methods of disinfection and stratification on in vitro seed germination, a factorial experiment laid out in a completely randomized design was set out to establish sterile plants out of seed culture. It was concluded that a pre-chilling treatment for 3 months resulted in maximum percent of germination (92%) and the largest germination rate. The best superficial sterilization protocol was proofed to be soaking in 70% (v:v) ethanol for 30 s and then, using of 2% (v:v) dilution of NaOCl for 15 min, followed by 3 rinses in sterile distilled water.

Studying the Efficiency of Floral Dip Method for Genetic Transformation of Apiaceae Plants
Plant tissue culture techniques are used as basic requirement of common plant transformation systems. In most cases of plant transformation, a reproducible regeneration protocol is the limiting step due to long time lasting, specialized facilities and well experienced persons. Furthermore, tissue culture procedures induce somaclonal variation among regenerated transgenic plants. Therefore, recently current studies in plant molecular biology prefer plant transformation procedures avoiding tissue culture phase. Various in plant a transformation procedures have been explored, among which the floral dip method is the most reliable in vivo transformation method. In this research, with the aim of evaluating the ability of floral dip method for genetic transformation of some Apiaceae plants, we studied Dill (Anethum graveolens), Fennel (Foeniculum vulgare), Coriander (Coriandrum sativum), Carrot (Daucus carrota), Parsley (Petrocelium sativum) and Celery (Apium graveolens). Arabidopsis thaliana was used as a model plant of experimental procedure. Flowers, in different stages of inflorescence development, were immersed in different suspension of Agrobacterium tumefaciens carrying the plant binary vector pBI121. This vector carries plant reporter gene uidA (gus) and the plant selectable marker gene npt II. Although, producing transgenic Arabidopsis plants with a high transformation rate of 4% verified the accuracy of experimental procedure, floral dip method was not successful for transformation of Apiaceae plants. Only one transformed celery plantlet, carrying nptII gene with no expression of GUS, was obtained bby screening more than 10000 seeds produced by treated plants from all the species. Transgenic Arabidopsis plants expressing gus reporter gene were confirmed through PCR and histochemical assays.

Effect of Nitrogen Form and Oxygen Levels in Nutrient Solution on Growth and Some Macronutrients in Hydroponically Grown Lettuce (Lactuca sativa cv. Great leak)
In this study the effect of nitrogen form and different oxygen levels on growth and development and macronutrients concentrations in lettuce plants was investigated. This investigation showed that sole ammonium application caused fresh and dry weight reduction of shoot and root in lettuce plant. But different oxygen levels had no effect on them. Nitrogen concentration of shoot was higher in ammonium treatments compared to nitrate treatment and with increasing of oxygen levels in the presence of ammonium, nitrogen content also increased, although it was not the same in nitrate treatment. Phosphorous concentrations in shoot and root were not affected by any of treatments and their interaction. Ammonium also caused reduction of potassium concentration in shoots, but different oxygen levels and its interaction with nitrogen form had no significant effect on it. Magnesium content of shoot also decreased in the presence of ammonium, although it was not the same in root. With increase of dissolved oxygen level, magnesium content of shoot decreased in ammonium treatment, but in nitrate treatment the concentration of this element was not affected by oxygen levels. It is concluded that probably reduction of potassium and magnesium in ammonium-fed plants has a role in plant growth reduction, and it was also observed that in spite of increase in the concentration of shoot nitrogen and root magnesium with increase of dissolved oxygen level in ammonium treated plants, lettuce growth was not affected by oxygen levels.

Study of Comparison and Adaptation of 15 Iranian and Foreign Olive (Olea europaea L.) Cultivars Under Sar-e-Pol-e- Zehab Conditions
In order to study adaptation ability of 15 commercial olive cultivars, this experiment was carried out using a randomized complete block design with three replication during the period from 2007 to 2009 in dry-warm climate of Sar-pol-e-Zehab Dallaho olive station of Kermanshah province. In this experiment, vegetative and reproductive traits were measured according to I.O.O.C. descriptors. Flora emergence was significantly different over years and among cultivars and flowering period appeared from end March to early May. Korneiki, as the late ripening cultivar, produced the smallest fruits (0.59 gr/fruit) among other cultivars. The highest fruit set, dry matter and content of oil accumulation (12.1%, 12.2%) in fresh matter were recorded in Amphisis and Korneiki cultivars, respectively. Mary was early ripening cultivar and it had the least dry matter and oil in fresh matter (5.2%). Conservalla cultivar had the most fruit weight (4.2 gr/fruit), flesh and yield per hectare (6700 kg/ha). On the other hand, the least percentage of fruit set and yield was obtained in Gorgan1 genotype (720 kg/ha) and Roghani Roodbar cultivar (637 kg/ha). The results indicated that temperature played a major role in delay of flowering by affecting phonological statue and development of flowers. It also oil content in olive affected by environmental condition and genetic background of cultivars. Finally, Olive Table cultivars (Conservalia, Manznilla and Sivillano), Zard-e- ziton (Dual-Purpose) and Oil Amphisis cultivar were better than the others for Sar-e-Pol-e- Zehab weather conditions.

The Effect of Root Partial Salinization on the Photosynthesis Rate and Nutrient Concentration in Strawberry
Salinity affects the yield and quality of fruits crops as result of modifying water and nutrient uptake. In split root system, it should be possible to reduce the deleterious effect of salinity on the plant growth. Therefore, an experiment was conducted on strawberry with different concentration of NaCl (0, 30, 60 and 90 mM) in a completely randomized blocks design in studding hydroponic greenhouse. The roots were divided into two portions and either even or uneven salinity was applied to the root portions. The treatments consist of 0:0, 0:30, 0:60, 0:90, 30:30, 60:60 and 90:90 with three replications. In general, the increased salinity reduced photosynthesis rate but in uneven salinity the photosynthesis rate was increased. Proline concentration was reduced in 0:0 treatments but increased in 0:30 and 30:30 treatments. Ca, N, P and K concentrations were reduced by increasing salinity, but were increase in uneven salinity. The highest concentrations of Cl and Na were observed in 60:60 and 90:90 salinity treatments. Na and Cl concentrations were reduced in uneven salinity in the root zone so that in 0:30 treatments, the concentration of Na were 20% lower than that in 30:30 treatments. Based on the results of this study the application of uneven salinity in a concentration of 30 mM could be recommended for growing strawberry in salinity stress conditions.

Possibility of Increasing Irrigation Period Without Decreasing Growth of Rose Saplings by Implementing Super Absorbent Polymer Trawat A200 in a Semi Arid Region
One fundamental strategy for increasing efficiency of plans which aim to develop natural resources is decreasing water loss and using this restricted water optimally. In arid and semi-arid regions such as a large part of Iran, increasing period of irrigation which results in decreasing the irrigation costs, without causing water stress to planted sapling is a vital task. In this research we examined the effect of using super absorbent on increasing irrigation period and growth of Rose's saplings. The experiment designed in randomized block with two factors (super absorbent in 4 levels 0, 40, 90 and 140 g. and irrigation period in 4 levels 6, 10, 14 and 18 days) and 3 replications. The results indicated that using super absorbent make it possible to increase irrigation period, while surprisingly causes some increases in growth of saplings. Considering height growth of saplings, 10 days irrigation period with 40 g super absorbent and based on collar and crown growth of 14 days with 140 g. were the best treatments. It means that these treatments which implemented the minimum amount of super absorbent lead to decreasing irrigation period while growth of saplings in contract to saplings in control treatment had no significant decrease.

In current study, seven organic fertilizers including; Leaf Mold (LM), Rice Husk (RH), Manure, Spent Mushroom Compost (SMC), mixture of LM, RH and SMC (M 1), mixture of LM, RH and Manure (M 2) with the ratio of 1:1:1 and control (no fertilizer) along with some levels of soil compactness comprising roller weights of 36, 56, 76 kilogram were used. Treatments were applied in a strip plot design with three replications, in research farm of Gorgan University of Agricultural Sciences and Natural Resources during fall 2008-2009. Effects of these treatments were investigated on chlorophyll content of lawn, amount of density and cover rate, growth height and percent of plant dry matter in fall season. According to results, SMC and RH treatments in first compactness, manure and M2 treatments in second compactness and manure treatment in third compactness showed the maximum chlorophyll content. The most and the least amount of nitrogen in each three compactness levels were observed in manure and control treatments, respectively. The highest density was related to manure treatment and the lowest one was related to LM treatment. In each three compactness, maximum and minimum height was observed in manure and control treatments, respectively. This project results will be used for lawn management in relation to the use of organic fertilizer and compactness rate of planting bed in Gorgan city conditions.

Effect of Population Type and BAP Treatments on In vitro Regeneration of Hyssop (Hyssopus officinalis L.)
Hyssop (Hyssopus officinalis L.), belongs to the family of Lamiaceae which its origin is Asia Minor, and is considered as one of the most important medicinal plant. This experiment was done to study the effects of population and BAP concentrations on hyssop plant regeneration under in vitro culture conditions. This research were performed in factorial experiment with three populations (Hamadan, Shiraz and Mashhad) and four levels of BAP (0, 2.2, 4.4, 13.2 µM), in three replications. Results showed that there is significant difference between populations. In all three populations, the lowest average and percentage of regeneration was observed in MS medium without any growth regulators. In Hamadan population, the highest average of regenerated shoots (7.86) and percentage of regeneration (86%) was obtained in BAP (4/4 µM) and in Shiraz population, maximum number of regenerated shoots (7) and 80% regeneration percentage was observed on 4.4 µM BAP. The minimum regeneration percentage with 0% was obtained in MS medium without plant growth regulators and MS media supplemented with 13.2 µM concentration of BAP. 2.2 µM BAP in Mashhad population with an average of 9 regenerated shoots and 86% regeneration percentage was known as the best treatment. ANOVA results showed significant (P < 0.01) effect of IBA levels on root induction. The highest rooting percentage (86.66%) was achieved in MS medium supplemented with 9.84 µM of IBA and the lowest rooting percentage (0%) was observed in 1/2 MS hormone-free medium.

Influence of Effective Microorganisms on Flower Buds Formation of Two Almond Genotypes in Water Stress Conditions
The base of nut production in almond is flower buds set with best quality and quantity. Although the process of flower buds set is controlled by genetic characteristics, however it affected with inside and outside diverse factors. To understand relationship between these factors for achieve to annual and regular nut production economically. An experiment was conducted in order to evaluate effects of effective microorganisms (EM) under water stress conditions on bud flower formation in two genotypes of almond trees in Department of Horticultural Science, Faculty of Agriculture, Ferdowsi University of Mashhad, in 2011. In this research effects of two different concentrations (0 and 5%) of EM and three levels of aridity stress treatments (100, 66, and 33% of FC) on number of flower buds in two genotypes (H1and H2) of almond was evaluated. This experiment was arranged as a factorial experiments based on a randomized complete blocks design with four replications. Results showed that the EM increased amount of leaf area, chlorophyll, storage protein, N, K and P in leaves. In this research, effects of different genotypes, EM and irrigation levels on number of flower bud set were significantly different at the %1 level. Number of flower bud formation increased by treatments of EM application, H1 genotype and irrigation level of FC% 100. There was significant interaction between treatments for this trait at %1 level. The best result was obtained from interaction between H2 genotype and irrigation using level of FC% 100 and EM application.
