There is substantial diversity in Achillea biebersteinii plants in Iran. It has considerable different biological activities including antibacterial, antifungal, antioxidant, insecticidal, herbicidal and wound healing. Research improvement for medicinal plants depends on the available genetic diversity. The assessment of genetic variability could increase the information for breeding programs. ...

We explore how diet diversity differs with agricultural seasons and between households within pastoral and agro-pastoral livelihood systems, using variety of foods consumed as a less complex proxy indicator of food insecurity than benchmark indicators like anthropometry and serum nutrients. The study was in the central part of the rangelands in Uganda. Seventy nine households were monitored for...

Loss of varietal diversity is a worldwide challenge to crop species at risk for genetic erosion, while the loss of biological resources may hinder future breeding objectives. Loss of varieties has been mostly investigated in traditional agricultural systems where variety numbers are dramatically high, or for most economically important crop species for which comparison between pre-intensive and...

Simple sequence repeat (SSR) markers were used to characterize genetic diversity in 30 sorghum [Sorghum bicolor (L.) Moench] accessions conserved in the national gene bank of Botswana. This collection represents the three sorghum-growing agro-ecological zones in the country. Ten microsatellite primer pairs were used, and these generated a total of 53 alleles with three to seventeen alleles per ...

The nutritive value of alsike clover (Trifolium hybridum L.) is slightly lower than that of red and white clovers; however, it exhibits some advantages – persists longer in a sward, performs well on acid and wet soils, suits for forage and silage production, can be used as green manure, and is a melliferous plant. With declining liming volumes, the soils are rapidly acidifying, which may result...

biodiversity refers to all forms of living animals, plants and microorganisms and agro-biodiversity is a component of biodiversity that represents diversity in arable lands. the aim of this study was to determine the biodiversity status of agro-ecosystems of shahr-e-rey city located in south of tehran, through calculating species richness index using rarefaction method. to the collect required ...

Genetic variation and population structure among 1603 soybean accessions, consisted of 832 Japanese landraces, 109 old and 57 recent Japanese varieties, 341 landrace from 16 Asian countries and 264 wild soybean accessions, were characterized using 191 SNP markers. Although gene diversity of Japanese soybean germplasm was slight lower than that of exotic soybean germplasm, population differentia...

Due to the important role of arbuscular mycorrhizal fungi (AMF) in ecosystem functioning, determination of the effect of management practices on the AMF diversity in agricultural soils is essential for the sustainability of these agro-ecosystems. The objective of this study was to compare the AMF diversity in Prunus persica roots under two types of fertilisation (inorganic, with or without manu...
