Digestive enzymatic activity and nutritional responses of Autographa gamma (L.) (Lepidoptera: Noctuidae), an important insect pest of sugar beet, on nine sugar beet cultivars (Peritra, Karolina, Paolita, Lenzier, Tiller, Ardabili, Persia, Rozier, and Dorothea) were studied. The highest proteolytic activity of fourth and fifth instar of A. gamma was in larvae fed on cultivar Persia. The highest ...
Investigations of the effects of elevated ozone (O(3)) on the virus-plant system were conducted to inform virus pathogen management strategies better. One susceptible cultivar of tobacco (Nicotiana tabacum L. cv. Yongding) and a resistant cultivar (Nicotiana tabacum L. cv. Vam) to Potato virus Y petiole necrosis strain (PVY(N)) infection were grown in open-top chambers under ambient and elevate...
To evaluate the response of wheat genotypes to terminal drought stress and to identify drought tolerant and sensitive genotypes, 20 wheat genotypes were compared in two stress and normal conditions, in a field experiment carried out at the Experimental Farm of College of Agriculture, Shiraz University, Shiraz, Iran, as a split-plot arrangement using complete randomized blocks design with four r...
cantaloupe (cucumis melo var. cantalopensis) is an important vegetable crop and is grown on 35000 hectares in iran, mostly in tehran, markazi, qom, esfahan, khorasan, semnan, booshehr and hormozgan provinces. to improve local semsoori population for concentrated yielding, a breeding program was initiated in 2000 in varamin agricultural research center, varamin, iran. in the first step a mass se...
a reliable dna extraction method for use on extra virgin olive oil based on a commercial kit was defined, and the possibility of using this dna for fingerprinting the original cultivar was demonstrated. the genetic traceability of single-cultivar virgin olive oil from two cultivars (carolea and frantoio) was achieved by identifying the varieties from which they were produced. this involved the ...
A sprouting-resistant and a sprouting-susceptible wheat cultivar were utilized to examine the role of ABA levels and sensitivity responses in wheat embryonic germination. Endogenous embryonic ABA levels were measured in both cultivars throughout grain maturation utilizing a new and sensitive ABA immunoassay. Embryonic ABA levels of each cultivar were similar with the sprouting-susceptible culti...
Safflower is an important, traditional, multipurpose oil crop. This was to investigate the effect of different salinity levels on morphological, physiological, biochemical and antioxidant response of two safflower cultivars (Carthamus tinctorius L. cultivar TSF1 and cultivar SM) differing in salt tolerance. Salinity stress (0.0%, 1.0%, 1.5% and 2.0% of NaCl) was induced to safflower plants afte...
this study was conducted to investigate the genotype¬×¬environment interaction effects on yield and yield components of wheat. ten cultivars of wheat were evaluated in 8 environments (combinations of two levels of nitrogen and four irrigation regimes) in growing season of 2006-2007 at the research farm of isfahan university of technology. based on the stability parameters of eberhart and russel...
selection of superior chance seedling genotypes is an important task in pear breeding programs. this research was carried out in order to explore and evaluate some of european pear (pyrus communis l.) chance seedling genotypes that are primarily used as rootstock for the asian pear (pyrus serotina rehd.) in tarbiat modares university (tmu) asian pear collection orchard. after four years visual ...
ابتلای ساختارهای انگشت به خصوص کپسول شاخی سم،به جراحات و آسیبهای مختلف مسبب اصلی تظاهر لنگش در گاو میباشد. مطالعه حاضر در یکی از کشتارگاههای اطراف شهر اردبیل صورت پذیرفت. در طول یک سال مطالعه مجموعاً30882 رأس گاو (نر و ماده) از نظر ابتلای به ضایعات نواحی انگشتی مورد بررسی قرار گرفت، که در این میان 7488 رأس (2/24 درصد) به جهت ابتلای به جراحات کپسول شاخی سم مورد شناسایی قرار گرفتند. در مقایسه...
