        In this research reaction of 10 Khuzetan native date palm cultivars clustered to 4 groups as as Dates with too much contamination including khadravi. Highly contaminated dates including Braim, Berhi, Gantar and Sayer. Dates with average contamination including Ashkar, Z More
        In this research reaction of 10 Khuzetan native date palm cultivars clustered to 4 groups as as Dates with too much contamination including khadravi. Highly contaminated dates including Braim, Berhi, Gantar and Sayer. Dates with average contamination including Ashkar, Zahedi, Chibchab and Raim. Slightly contaminated dates including Dayri. The characters such as bunch number, bunch weight, pedicel length, main stalk of bunch length, smallest stand lenght , stand number and sugar percent have significant correlation with lesser moth injury. Other haven’t significant correlation with lesser moth injury. Manuscript profile

        2 - The effect of planting date and varieties of canola on yield and population of the cabbage aphid, Brevicoryne brassicae L. (Hom., Aphididae)

        The cabbage aphid, Brevicoryne brassicae L. is one of the most important pests of canola which induces serious damage to the crop over the country. Use of resistant varieties along with proper sowing time, are IPM-based methods, which were studied in Saveh fields of Markazi province Iran through growing seasons of 2004-2005 and 2004-2005. We used a layout of split plot design consisting of varieties of RGS003, Licord, PF, and SLM046 (as main plots) and 3 sowing dates of 20 Sep. 5 Oct. and 10 Nov.(as sub plots) at 3 replicates, Natural aphid infection was sufficient. The aphid density was estimated by counting occurance of the pest number on one centimeter of the upper parts of the 10 randomly selected canola stems. Also yields of each plot were measured using a quadrate of 1 ×1m. Results showed that first date of planting (22th Sep.) during both years of study produced significantly highest yield (139.33 & 149.97 kg/ha) respectively but the lowest density of aphids (20.88& 13.05) per sampling unit. The cultivar "RGS003" which yieldied 146.67 and 144.84 kg/ha and attracted 32.56 and 48.67 aphids in both years of study was evaluated as superior cultivar to others. Overall results suggest the date of first planting and "RGS003" cultivar for the region of study. Manuscript profile

        شوری خاک و آب موجب کاهش رشد و تولید محصولات کشاورزی می­شود. برای بررسی تغییرات مورفولوژیکی ایجاد شده در واریته­های لیسیانتوس تحت شوری کلرید کلسیم آزمایشی در گلخانه­های پژوهشی دانشکده کشاورزی دانشگاه لرستان انجام شد. واریته­های لیسیانتوس شامل شامپاین، فسفری، لب بنفش و سفید تحت شوری کلسیم کلراید (0، 5، 10، 15، 20، 25 و 30 میلی مولار) قرار گرفتند و واکنش مورفولوژیکی ارقام بررسی شد. نتایج نشان داد که شوری همه پارامترهای بررسی شده را تحت تاثیر قرار داده است به طوری که با افزایش سطوح شوری ارتفاع، وزن تر و خشک شاخساره و سطح برگ در همه واریته­ها کاهش پیدا کرده است، در حالی­که طول ریشه، وزن تر و خشک ریشه و همچنین نسبت طول ریشه به شاخساره افزایش نشان داده است. نتایج نشان داد میزان تغییرات در رقم سفید و فسفری کمتر از لب بنفش و شامپاین بوده است. آنالیز رگرسیون رابطه سطوح شوری و ارتفاع گیاهان (درصد نسبت به شاهد) دو گروه مجزا با شیب خط متفاوت نشان داد، به اینصورت که رقم‌های شامپاین و لب بنفش به عنوان ارقام حساس و رقم‌های سفید و فسفری به عنوان ارقام مقاوم در دو گروه مجزا قرار گرفته اند. نتایج نشان داد آستانه مقاومت به شوری در رقم لب بنفش و شامپاین به ترتیب 30 و 25 میلی مولار بوده است در حالی­که ارقام سفید و فسفری در سطوح شوری 30 میلی مولار اختلاف معنی داری با شاهد نداشته اند. با توجه به نتایج به دست آمده و کاهش کمتر ارتفاع، تعادل آبی، وزن تر و خشک شاخساره و همچنین سطح برگ در واریته­های سفید و فسفری، به نظر می­رسد این واریته­ها نسبت به واریته­های شامپاین و لب بنفش مقاومت بیشتری نسبت به شوری کلسیم کلرید داشته باشند.

           Powdery mildew is one of the most serious diseases of grapevine in all over the world including Iran. It can impose remarkable losses to grapvien orchards in favorable condition. In this experiment, 14 cultivars of grapes including Shahani, Kishmishi, Rasmi, Tokolgan, Garashilig, Seyrakpousteh, Khalili, Tabarzeh, Koupakbogan, Aldarag, Sahibi, Agshilig, Yagothi and Tabriz-kishmishi were evaluated under natural infection and artificial inoculation during 2007- 2008 in Meshkinshahr region. Disease severity on leaf and fruit cluster was evaluated by Wang and Voytovich scales in which 0: immune, 1: very resistant, 2: resistant, 3: tolerant, 4: susceptible and 5: very susaptable. Shahani, Yagothi and Tabriz-kishmishi cultivars were Immune, Sahibi was highly resistant, Agshilig and Tokoulgan were resistant, Kishmishi, Khalili and Tabarzeh were tolerant, Aldarag and Koupakbogan were susceptible and Garashilig, Seyrakpousteh and Rasmi were highly susceptible to powdery mildew. In general, in highly infected areas, using Shahani, Yaghuti, Tabriz-kishmishi would be more recommendable for new grapevine orchard establishment. Manuscript profile
