Combining plant genetic resistance with architectural traits that are unfavorable to disease development is a promising strategy for reducing epidemics. However, few studies have identified root system architecture (RSA) traits with the potential to limit root disease development. Pea is a major cultivated legume worldwide and has a wide level of natural genetic variability for plant architectu...

As the largest developing country, China has permanently attached great importance to cultivated land protection. However, due different rules of identification in second and third national surveys, area two surveys changed greatly. Some agricultural lands south, such as plantations, forests, grasslands, aquaculture ponds, etc., belonged during survey, but they were identified non-cultivated su...

In this study, two polysaccharides (Elaeagnus angustifolia L. polysaccharide-1 (PEA-1) and PEA-2) were prepared from Elaeagnus angustifolia L. Then, the preliminary structure and antioxidant activities of all the samples were investigated. The results showed that the average molecular weights for PEA-1 and PEA-2 were 9113 and 5020 Da, respectively. And, PEA-1 was mainly composed of rhamnose, xy...

Remote sensing has become a common and effective method for estimating the areal coverage of land cover classes. One class of particular interest is agriculture as area estimates of cultivated lands are important for purposes such as estimating yields or irrigation needs. The synoptic coverage of satellite imagery and the relative ease of automated analysis have led to widespread mapping of agr...

present research was conducted with the aim of determination of significant effect of soil properties on natural regeneration of haloxylon aphyllum and correlation coefficient and linear relation between soil variables and natural regeneration of haloxylon aphyllum. firstly, geomorphologic units were prepared in the areas under cultivation of haloxylon aphyllum in ardestan. two cultivated lands...

Abstract Background Antibiotics used to treat livestock species enter agricultural fields when they are excreted by grazing animals or present in manure that is added as fertiliser. In the European Union, potential effects of such antibiotics on terrestrial plants must be evaluated following standardised OECD 208 method, which specifies crop and wild should serve “sentinels” for assessing antib...

Ancient DNA (aDNA) is any DNA extracted from ancient specimens, important for diverse evolutionary researches. The major obstacles in aDNA studies are mutations, contamination and fragmentation. Its studies may be crucial for crop history if integrated with human aDNA research and historical linguistics, both general and relating to agriculture. Legumes (Fabaceae) are one of the richest end eco...

in order to investigate the effects of biological and chemical phosphorous fertilizers and various proportions of maize and grass pea intercropping on yield and yield components of both crops, two experiments were conducted simultaneously in research farm of kerman university and commercial convention farm of bardsir-dashtkar in 2009-2010. the experimental design at two regions was randomized c...
