Today’s agriculture is not only confronted with the production of food and animal food, but also with aspects of environmental protection. In today’s crop production, there is an increasing pressure to reduce the use of pesticides, to decrease the environmental impact and to lower potential production costs. It is therefore imperative that pesticides are only applied when and where needed. Dise...
سابقه و هدف: بیماری لکه برگی سپتوریایی (STB) که توسط قارچ آسکومیستMycosphaerella graminicola (anamorph S. tritici) ایجاد میشود به عنوان یکی از اصلیترین عوامل خسارتزای زنده در تولید گندم در جهان مورد توجه میباشد. این آزمایش به منظور مطالعهی نحوۀ عملکرد ژن-های مقاومت بهM. graminicola، تعیین تعداد ژنهای مسئول در ایجاد واکنش مقاومت و برآورد اجزاء ژنتیکی مقاومت پیریزی شده است. مواد و روشها:...
Septoria tritici blotch or leaf has been used for long time, but is a correct disease name. Moreover, Lb resistant gene the name, but, not Stb gene. It sexual and asexual parts on mycelia, known as heterothallic fungi. Its pathogenic diversity ranged from 40% to 93% produced wide variety of AvrLb6 haplotypes. M. graminicola plasmogamy karyogamy process. The pathogen can use macropycnidiospores,...
Catalases, peroxidases, and catalase-peroxidases are important enzymes to cope with reactive oxygen species in pro- and eukaryotic cells. In the filamentous fungus Aspergillus nidulans three monofunctional catalases have been described, and a fourth catalase activity was observed in native polyacrylamide gels. The latter activity is probably due to the bifunctional enzyme catalase-peroxidase, w...
Abstract Reduced tillage is considered as one of the main tools to save biological diversity; however, it increases pressure diseases, including wheat leaf blotches. The aim present study was clarify impact reduced soil on development winter blotches in different schemes crop rotation. growing technologies severity disease evaluated a two-factorial experiment: A – system, and B combinations pre...
Abstract Breeding of multi-resistant varieties to reduce yield loss due disease damage and lodging, reduction input intensity are high importance for a more sustainable cereal production. The aim this study was evaluate (i) caused by diseases lodging (ii) impact soil fertility in variety trials grown under two intensities. Intensity 2 treated with 1 without fungicides growth regulators. We appl...
