This study aims to investigate the effect of a methanol extract of Trachyspermum ammi (L.) as an antiepileptic agent. Tests were conducted with a singleand multiple-dosing schedule of Trachyspermum ammi (L.), using a strychnineinduced seizure model for epilepsy. Twenty-one animals were divided into three groups; control (vehicle), standard (diazepam) and test (Trachyspermum ammi (L.) extract). ...
این تحقیق در جمعیتی متشکل از 103 لاین دبل هاپلوئید ( dh ) و والدین آنها و 5 رقم گندم نان بومی ایران، در سه سال زراعی (1388-1386) در قالب طرح لاتیس مستطیل (11×10) سه گانه در مزرعه اجرا گردید. نتایج تجزیه امی عملکرد دانه در واحد سطح نشان داد: اثرات اصلی سال، ژنوتیپ و اثر متقابل آنها معنی دار (01/0 p< ) بوده که نشان دهنده تأثیر زیاد این عوامل بر عملکرد دانه بود. دو مؤلفه اول امی ( ipca ) تمامی تنو...
A procedure is described for the isolation of native DNA from protoplasts of ammi (Ammi visnaga) and carrot (Daucus carota) cells. Protoplasts were produced from 40 grams of fresh cells by enzyme hydrolysis and lysed with sodium dodecyl sulfate. The DNA was purified by treatment with pronase and ribonuclease. Final isolation was achieved by sucrose density gradient centrifugation.The melting te...
Linear-bilinear models, especially the additive main effects and multiplicative interaction (AMMI) model, are widely applicable to genotype-by-environment interaction (GEI) studies in plant breeding programs. These models allow a parsimonious modeling of GE interactions, retaining a small number of principal components in the analysis. However, one aspect of the AMMI model that is still debated...
We evaluated the phenotypic and genotypic stability and adaptability of hybrids using the additive main effect and multiplicative interaction (AMMI) and genotype x genotype-environment interaction (GGE) biplot models. Starting with 10 single-cross hybrids, a complete diallel was done, resulting in 45 double-cross hybrids that were appraised in 15 locations in Southeast, Center-West and Northeas...
Thirty six wheat genotypes derived from diallel crosses from F1 to F3 and their parents were evaluated in six different environments for the stability of performance. Performance was measured by seed yield per plant under drought and non-drought stress conditions. The experiment was conducted as a randomised complete block design with three replications in over one year. Additive main effects a...
This study was performed to investigate effect of essential oils on Aspergillus spore germination, growth, and mycotoxin production. In vitro antifungal and antiaflatoxigenic activities of Cymbopogon martinii, Foeniculum vulgare, and Trachyspermum ammi essential oils were carried out on toxigenic strains of Aspergillus species. Plant materials were hydrodistilled for 4-5 h in Clevenger apparatu...
به منظور بررسی کارایی روش AMMI و تجزیه واکنش ژنوتیپی در تجزیه پایداری ارقام چغندرقند، تعداد 17 رقم چغندرقند در 13 منطقه و در طی سه سال مورد مقایسه قرار گرفته و صفات عملکرد ریشه و عیار قند اندازهگیری شد. در تجزیه واریانس مرکب آزمایشها اثر رقم و اثر متقابل رقم × محیط برای هر دو صفت معنیدار بود. ارقام مورد مطالعه با استفاده از روشهای ابرهارت و راسل، اکووالانس ریک، واریانس پایداری شوکلا، روش AM...
When you are faced with analyzing two-way cross-classified experiments, you are almost always interested in whether the two factors interact or not, and if they do interact, combinations of the two factors are responsible for the interaction in the data. When there are no independent replications, there are no traditional tests for interaction. SAS® macros have been developed to provide user-fr...
دستیابی به ارقام گندم با عملکرد بالا و پایدار و واجد صفات مطلوب مرفو- فیزیولوژیک از اهداف اصلی برنامه های بهنژادی گندم می باشد. جهت تعیین پایداری عملکرد دانه و سازگاری، 18 ژنوتیپ پیشرفته گندم زمستانه و بینابین در قالب طرح آماری بلوک های کامل تصادفی با 3 تکرار در 2 سال زراعی 87-1385 در 9 ایستگاه تحقیقاتی اقلیم سرد کشور(کرج، اراک، اردبیل، جلگه رخ، میاندوآب، همدان، مشهد، قزوین و خوی) مورد ارزیابی ...
