Plants of Asteraceae are used in traditional medicine and phytotherapy. The two main caffeic acid derivatives, chicoric and caftaric acid which are found in many genus of Asteraceae including Echinacea exhibit important biological activities. The level of these acids in E. purpurea is affected by many factors such as growing situations, extraction methods, storage condit...

Budding is a good method of propagation in the Persian walnut (Juglans regia L.)., However, success of budding is low due to higher root pressure as well as the presence of phenolic compounds in the xylem sap. This study was conducted to compare various budding methods and cut below budding union on two and three-year-old Persian walnut under field conditions. The experiment was conducted based...

root and crown rot of sugar beet caused by rhizoctonia solani ag2-2 is a destructive disease in the main sugar beet growing areas. use of resistant cultivars is the most effective and environmentally safe way to control the disease. in order to find resistant genotypes, 70 sugar beet lines together with resistant and susceptible checks were evaluated against a highly virulent isolate of r.solan...

I compared growth and arbuscular mycorrhizal fungal (AMF) colonization of two prairie grasses (Wild rye [Elymus canadensis] and Little bluestem [Schizachyrium scoparium]), an earlyand a late-dominating species in prairie restorations, respectively, grown in soil from restored prairies of differing age, soil characteristics, and site history. There were no consistent patterns between restoration...

The experiment was carried out during 2015-2016, with the aim of investigating the effects of scion cultivar, rootstock age and hormonal treatments on the success of walnut minigrafting. Analysis of results showed that all studied factors were effective on graft-take and survival of minigrafted walnuts and other growth traits of the scions. The highest graft-take was observed on one-year-old ro...
