به منظور بررسی تاثیر عوامل اقلیمی و خاکی بر پراکنش علفهایهرز در چمن، پژوهشی در45 بوستان در 22 منطقه شهر تهران، در سال 1393 انجام شد. با استفاده از آنالیز چند متغیره همبستگی کانونی (CCA)، ارتباط پراکنش گونههای علفهرز با عوامل خاک (اسیدیته خاک، نیتروژن، فسفر، پتاسیم، درصد کربن، درصد ماده آلی و EC) و عوامل اقلیمی بررسی شد. نتایج نشان دادکه علفهایهرز دم روباهی سبز (Setaria viridis(L.) P....
A redescription of Cryptosporidium galli Pavlasek, 1999 (Apicomplexa: Cryptosporidiidae) from birds.
Cryptosporidium galli Pavlasek, 1999, described from the feces of birds, is redescribed with additional molecular and biological data. Oocysts are ellipsoidal, are passed fully sporulated, lack sporocysts, and measure 8.25 x 6.3 microm (range 8.0-8.5 x 6.2-6.4 microm) with a length-width ratio of 1.30 (n = 50). Oocysts are structurally similar to those of Cryptosporidium baileyi described from ...
We have isolated five endophytic fungi from the roots of Capsicum annuum, Cucumis sativus and Glycine max. The culture filtrates (CF) of these endophytes were screened on dwarf mutant rice (Waito-C) and normal rice (Dongjin-byeo). Endophyte CAC-1A significantly inhibited the growth of Waito-C and Dongjin-byeo. Endophyte CAC-1A was identified as Paraconiothyrium sp. by sequencing the ITS rDNA re...
The genus Echinochloa (Poaceae) includes numerous problematic weeds that cause the reduction of crop yield worldwide. To date, DNA sequence information is still limited in the genus Echinochloa. In this study, we completed the entire chloroplast genomes of two Echinochloa species (Echinochloa oryzicola and Echinochloa crus-galli) based on high-throughput sequencing data from their fresh green l...
آگاهی از سیستم تولید مثلی گونههای گیاهی به تعیین تغییرات ژنتیکی و سازگاری آنها در صورت کاشت در محیطهای جدید کمک خواهد کرد. با توجه به اهمیت اسپرس به عنوان گیاهی علوفهای، بذر سیزده جمعیت اسپرس (Onobrychis) شامل گونههای یکساله O. crista-galli، O. pulchella، O. caput-galli و O. micrantha و همچنین دو گونه زراعی و چند ساله O. viciaefolia و O. altissima در سال زراعی 89-1388 در قالب طرح بلوکهای...
Thirty-seven commercial aldehydes containing aliphatic chains and aromatic rings as well as heteroaromatic rings were evaluated for their inhibitory activities against Chinese amaranth (Amaranthus tricolor L.) and barnyardgrass (Echinochloa crus-galli (L.) Beauv). Polysorbate 80 (Tween® 80) was used as a surfactant and the research was preliminarily conducted at 400 μM of all aldehydes. Among t...
Acetyl-coenzyme A carboxylase (ACCase) plays crucial roles in fatty acid metabolism and is an attractive target for herbicide discovery. Metamifop is a novel ACCase-inhibiting herbicide that can be applied to control sensitive weeds in paddy fields. In this study, the effects of metamifop on the chloroplasts, ACCase activity and carboxyltransferase (CT) domain gene expression in Echinochloa cru...
Poultry farming not only provides high nutritious food but also creates employment opportunity for rural masses. Documented evidences elaborates that helminth parasitism is most deciduous problem of chickens especially in developing world. Ascaridia (A.) galli, a nematode of small intestine, has been considered as the most common and important parasite of chicken. The present study was carried ...
