Changes in water content and dry weight were determined in control cells and those induced to cold harden in response to abscisic acid (ABA) treatment (7.5 x 10-5 molar). Bromegrass (Bromus inermis Leyss cv Manchar) cells grown in suspension culture at room temperature (230C) for 7 days acclimated to -28°C (LT50) when treated with ABA, or to -50C when untreated. ABA significantly reduced cell g...
چکیده به منظور بررسی اثر تنوع گیاهی و نوع منبع تغذیه ای بر تنوع و تراکم علفهای هرز و حشرات، کارایی مصرف نهاده ها ( نور، آب، عناصر غذایی) و عملکرد و خصوصیات کیفی چند گونه زراعی، آزمایشی به صورت کرتهای خردشده بر پایه طرح بلوکهای کامل تصادفی با سه تکرار در دو سال زراعی 1385-1384 و 1386-1385 در مزرعه تحقیقاتی دانشکده کشاورزی دانشگاه فردوسی مشهد به اجرا درآمد. تیمارهای مورد بررسی دو منبع کود دامی و...
the effect of salinity on growth, inorganic ions and dry matter partitioning in sugar beet cultivars
this study investigated intra-specific variation in the growth parameters and dry mat-ter partitioning of sugar beet cultivars at different levels of salinity (0, 50, 150, 250 and 350 mm nacl + cacl2 in 5:1 molar ratio) using four cvs, one british (madison) and three iranian cvs (7233-p12, 7233-p21 and 7233-p29). the plants were grown in a controlled greenhouse environment for about 18 weeks. a...
in order to study of effects of deficit irrigation on morphological traits and growth indices variation of corn forage (sc. 704) in rasht region, an experiment based on randomized complete design with four treatments and three replication was conducted in 2007 growing season, at research farm of faculty of agriculture, university of guilan. experimental treatments consisted of: no-irrigation, 1...
the nutritive values of non- processed and processed grape pomace with neurospora sitophila were evaluated. the chemical compositions and physical characteristics of samples were evaluated by laboratory analysis. an in vitro digestibility experiment was done to determine digestibility coefficients of dry matter, organic matter and also digestible organic matter in dry matter (domd) to estimate ...

salinity is a major environmental problem in arid and semi-arid areas. chickpea (cicer arietinum l.), like other legumes is sensitive to salinity. therefore, selection of genotypes to grow on saline areas is important. eleven chickpea genotypes (as sub plots) were grown in the greenhouse conditions on a medium containing different nacl concentrations (8 and 12 dsm-1) and control (hoagland solut...
physiological changes of wheat plants which seed pretreated by salicylic acid under late sowing date
wheat, cv. alvand, under late sowing condition and comparison with conventional sowing date was investigated in a field experiment in 2009-2010. the factors were seven levels of priming by sa, including control or untreated seeds, 400, 800, 1200, 1600, 2000 and 2400 µm sa and two sowing dates including conventional sowing date (23 october) and late sowing (22 november). results showed that prim...
in this study, the effects of oleothermal modification on physical and mechanical peroperties of fir wood (abeis sp.) blocks were examined. at first, some blocks of fir wood with 5 × 20 × 120 cm dimensions were prepared. the blocks were treated in soybean oil. the effects of 3 factors such as treatments temperature (180and 200 °c), holding time (12 and 15 h) and initial moisture content of wood...
تأثیر مقادیر مختلف نیتروژن بر رشد و بررسی رابطه نیترات دمبرگ و شاخص کلروفیل با نیترات هیپوکتیل تربچه
The aim of this study was measuring nitrate and leaf chlorophyll content in aerial parts of plant, from which we can predict the hypocotyl nitrate content of radish. A factorial experiment in a completely randomized design with five replicates was carried out on two varieties of radish (Cherry Belle and Sparker). Plants were grown in perlite containing pots and were treated with five levels of ...
