Abstract: 

During 1994-1997 a devastating and widespread dieback and decline on stone fruit trees especially on apricot, cherry and almond was observed in various regions of Semnan, Kerman and West Azarbaidjan provinces. Orchards in various parts of the provinces were surveyed and samples of affected roots, crowns, twigs and blossoms were collected and brought to the laboratory. Samples were taken weekly and surface sterilized and cultured on PDA, MA media and on PARPH without disinfection. On the basis of morphological and limited physiological characteristics, eight fungal species, namely Monilinia laxa,Verticillium dahliae, Phytophthora cactorum, Armillaria sp. Cytospora leucostoma, Cytospora sp. Pleospora sp., and Scytalidium dimidatum were identified. Pathogenicity tests of the all isolates were studied using two methods. For detached branches of apricot (cv Gaisi) and cherry (cv Black Mashad) and also inoculation 2-3 year- old seedlings were used in the greenhouse. Selected isolates of M.laxa were sparyed on 3-4 year old apricot seedlings with suspension of 5000 spores per mililiter in stage of early blossom and greenhouse condition. The result showed that only V. dahliae, P. cactorum and m. laxa were pathogenic on apricot and cherry.

Abstract: 

Oshnaviych plutonic complex (OPC), the western member of Urumiyeh-Golpayehgan intrusivc plutons is located in northern part of Sanandaj-Sirjan Zone. OPC, exposing in an area of about 700 km2, comprises 10 plutons that can be divided into three suites, i.e. diorite, granite and alkali syenite -alkali granite, Dioritic bodies are thc oldest intrusive rocks of the region, which on the basis of the field study, their relative age of emplacement is estimated to be Post- Jurassic and Pre-Miocene. However, with respect to the age of other similar intrusive bodies in Naghadeh area, they are most likely of Post Early Cretaccous - Pre Miocene age, Hybrid intrusive rocks, occurring at the contact of dioritic and granitie rocks may suggest a simultaneous emplacement of both magmas. Syenitic pluton from alkali granite-alkali granite suite has intruded dioritic and granitie rocks, in contrast, flourine bearing alkali granite pluton from this suite shows no contact with other igneous rocks in the area. K-Ar age determinations obtained on amphibole specimens from diorite suite are 91.9±2.3, 94.1±2.3 and 100±2.4 Ma, and on biotite specimens from granite suite are 100±1.5 to 98.9±1.5 Ma. Chronology study using same method on arfvedsonite specimens from syenite pluton shows 78.9±3.1, 79.6±1.9 and 81.7±2.0 Ma and on K-fledspar samples of fluorine bearing alkali granite pluton from the alkali syenite-alkali granite suite presents 76±3.4 and 77.1±1.8. Therefore, based on field evidence and K/Ar age dating, OPC presumably formed during two episodes: granite and diorite suites formed simultaneously at about 100 Ma, then plutons of alkali syenite-alkali granite suite emplaced at about 80 Ma.

Abstract: 

پتاسیم و کلسیم دو عنصر مهم در تعیین کیفیت میوه ها به ویژه سیب به شمار می روند. با توجه به تاثیرات متقابل بین این دو عنصر، مصرف متعادل هر یک از آنها جهت تنظیم نسبت پتاسیم به کلسیم حیاتی است و ضرورت دارد این نسبت در حد متعادلی نگه داشته شود. به منظور افزایش سفتی بافت میوه سیب، افزایش طول عمر انباری آن و تعیین بهترین نسبت پتاسیم به کلسیم در میوه، آزمایشی در نقده در سال زراعی 80-1379 با 9 تیمار در 5 تکرار در قالب طرح بلوکهای کامل تصادفی روی پایه بذری درختان 25 ساله رقم گلدن دلیشس (Golden delicious) انجام گرفت. تیمارهای آزمایشی عبارت بودند از تیمار 1= شاهد (کودهای ازت، فسفر و کودهای حیوانی به صورت پخش سطحی)، تیمار 2= T1 + کودهای میکرو به صورت چالکود، تیمار 3= T2 + کلرور پتاسیم بر اساس آزمون خاک، تیمار 4= T3 + محلول پاشی کلرور کلسیم نیم درصد در چهار مرحله، تیمار 5= T3 + محلول پاشی کلرور کلسیم نیم درصد در هشت مرحله، تیمار 6= T2 + محلول پاشی کلرور پتاسیم 50 درصد بالای آزمون خاک، T6=7+ محلول پاشی کلرور کلسیم نیم درصد در چهار مرحله، تیمار +T6=8 محلول پاشی کلرور کلسیم نیم در صد هشت مرحله، تیمار +T2=9 سولفات پتاسیم 50 درصد بالای آزمون خاک + محلول پاشی کلرور کلسیم نیم درصد در هشت مرحله.نتایج این بررسی نشان داد که سفتی بافت میوه سیب پس از محلول پاشی کلرور کلسیم در مقایسه با وقتی که میوه نسبت بالایی از پتاسیم بدون محلول پاشی کلسیم دریافت کند، بالا می رود. بیشترین سفتی مربوط به تیمار هشت )3.85 کیلوگرم بر سانتیمتر مربع) با هشت مرحله محلول پاشی کلرور کلسیم بود. در حالی که تیمار ششم با مصرف 50 درصد بالای آزمون خاک پتاسیم و بدون محلول پاشی کلسیم پایین ترین میزان سفتی )3.11 کیلوگرم بر سانتیمتر مربع( را به دست داد. لذا اختلاف میانگین سفتی بافت میوه در تیمارها در سطح 5 درصد معنی دار بود. سایر صفات کیفی میوه نظیر pH، اسیدیته، مواد جامد قابل حل، اختلاف معنی داری در بین تیمارها نشان ندادند. نسبت پتاسیم به کلسیم میوه ها در تیمار شاهد (K/Ca=44) بود که به حدود (K/Ca=58) در تیمار ششم افزایش یافت، اما در تیمار هشتم با مصرف متعادل کود و هشت مرحله محلول پاشی کلرور کلسیم نیم درصد این نسبت به محدوده (K/Ca=23) کاهش یافت. در نود روز بعد از انبارداری تیمارها روی سفتی بافت میوه هیچگونه اثری نداشتند.

Abstract: 

Crown and root rot of wheat is a major disease in West Azarbaidjan province. It caused heavy losses in commercial fields in 1997- 1998. In order to determine the causal agent of crown and root rot in irrigated and rainfed wheat fields, several samples were taken from various fields in West Azarbaidjan. The symptoms of disease observed on fully developed plants, were leaf blotch, common root rot, black joint, and head& seedling blight. Isolation of fungi was undertaken by plating pieces of discolored root and crown tissues on P.D.A and C.M.A petri plates. The isolated fungi were identified as Bipolaris sorokiniana, B. spicifera, Fusrium acuminatum, F culmorum and F avenaceum. Pathogeni city of each isolate was determined out using seed inoculationas well as mixing of the inoculum (wheat seeds colonized by the isolate) with pasteurized soil techniques. The results showed that Bipolaris spp. were pathogenic on their cultivar seedlings but Fusarilfm spp., which are probably aggravated by moisture stress at seedling stage of wheat due to poor irrigation management, showed symptoms of the disease only after moisture stress. The results also indicated that among all pathogens, B. sorokiniana had larger frequency and it was considered to be main pathogen of crown and root rot of wheat in irrigated fields of West Azarbaidjan province.

Abstract: 

The salinity and drought are two increasing stress in region soils. So that the selection of resistant cultivars is necessary and the most important. In order to study salinity and drought resistant of barley four cultivars named Sahand, Makoii, Naghadeh and CB were selected. By using randomized complete block design seeds of all cultivars were planted. The salinity and drought levels were respectively 5, 10, 15 & 20 gr/lit NaCl, ,25 ,50,100,150 gr/lit glucose. The results showed that in critical salinity (20 gr/lit NaCl) and drought (150 gr/lit) conditions the percentage germination of sahand and CB were respectively 80,27 &87,31. Then Sahand was resistant and CB sensitive cultivar. Sahand and CB were planted under field capacity F.C..Condition in three levels of F.C., 1/2 F.C., 1/4 F.C... After ten days concentration of free proline and soluble sugars in leaves and roots of seedling were determined. By increasing of drought stress, accumulation of proline and soluble sugars content leaves and roots of both cultivars were significantly increased. We experimented Alpha-amylas activity in four days seedlings that germinated under drought and salinity condition. Alpha- amylas activity in the Shand was higher than that in the CB. In electrophoresing (SDS-PAGE) of seedling protein of treatment under drought and salinity condition, the most differences were in some bands with 62.7, 43.35 and 28.68 KD molecular weight.

Abstract: 

The aim of this research was to compare the benefits of wheat enrichment in the farm with flour fortification in the factories. Three experiments have been carried out in the early of third Millennium in 6 different provinces, i.e. East and West Azerbaijan, Kerman, Sistan and Balouchestan and Southern Khorasan. The first and second experiments (2000-02 and 2002-04), were designed based on t-distribution and included two treatments: The control plots were given nutrients based on Farmer's conventional fertilization practice (NP) and the treated plots received nutrients based on soil tests (balanced fertilization) in Meyaneh (3 wheat farms) and Naghadeh (1 wheat farm) in East and West Azerbaijan provinces. In the wheat fields, micronutrient-fertilizer solution with 0.5% was sprayed at three stages (stem elongation, heading, and a week after flowering). After harvesting, the grain yield, phytic acid, Zn and PA/Zn molar ratio were measured. Then, whole-wheat bead and regular bread prepared from these farms were fed for 4 and 6-month periods to different groups in Tajark, Khanghah and Kahriz villages in East and West Azerbaijan, respectively. Before and after feeding the village inhabitants, zinc (Zn) and iron (Fe) concentration were measured in their blood serum. In the third experiments, in the summer of 2003, a study on the effect of fortification and improvement of the quality of bread on the health of consumer subjects was carried out on the total personnel of Moghadam Mersad Military Station. A number of the drafted military service personnel of Moghadam Mersad Military Station and some personnel from Ravar Aboozar Military Station were selected for blood tests. During a 4-month test period, bread consumed at the Station and the associated units was fortified and the correct procedure of baking was taught to the bakers. The amount of Zn and Fe in the blood serum of the subjects was determined with an atomic absorption spectrometer. Fortification of the wheat flour was carried out at the Baghin Martyrs Station, by adding, 80 mg Zn; 50 mg Fe; 10 mg vitamin B1; 2.5 mg Vitamin B2; and 5 mg vitamin B6 per kg of flour. In the first and second experiments, the results demonstrated that there was a significant difference at one percent level for grain yield (a=0.01). Also, the statistical analysis revealed a significant difference for phytic acid, Zn and molar ratio of phytic acid to Zn (PA/Zn) in all wheat farms. Consumption of whole wheat bread in comparison with white bread for 4 and 6-month periods noticeably increased Zn and Fe concentration in blood serum especially in 6-month period. While the average Zn and Fe concentration in the blood serum in the second experiment for the control was 80 and 100, they were increased to 110 and 130 mg/deciliters after the intervention in Kahriz village. In the third experiment, in places where bread was not fortified, the average level of Zn in the blood serum of individuals was measured to be 72 mg/deciliters; whereas, the serum Zn of the test subjects consuming fortified bread for a three-month period averaged 89 mg/deciliters (P<0.01). For persons who fed on unfortified bread, 47% suffered from Zn deficiency but those who used the superior quality, fortified bread, only 10% suffered from this deficiency (P<0.01). While the number of people using stomach-problem-related medicines at the Beghin Martyrs Station during a 4-month period before the experiment was figured to be 1615, it was reduced to 1375 cases after the test; or a 15% decrease during a 4-month period. In conclusion it can be mention that superiority of the enrichment in the farm over flour fortification in the factory has been proven. Enrichment is preferred to flour fortification and its most important benefits are at least 20% increase in wheat yield as well as grain quality and more than 10% increase in minerals concentration due to more uptake by human's digestion system.
