Metcalfa pruinosa (Say, 1830) is an invasive, gregarious sap-sucking insect that spreads rapidly through Ukraine and now detects in Kyiv city, the Autonomous Republic of Crimea, Donetsk, Dnipropetrovsk, Zakarpattia, Odesa, Kharkiv, regions. Additionally, this parasitizes more than 300 species plants, including common hop (Humulus lupulus L.). H. a valuable industrial crop grown many countries, ...

The knowledge about microorganisms-activity and diversity under hop production is still limited. We assumed that, different systems of hop production (within the same soil and climatic conditions) significantly influence on the composition of soil microbial populations and its functional activity (metabolic potential). Therefore, we compared a set of soil microbial properties in the field exper...

New antimicrobial properties of products derived from Humulus lupulus L. such as antiadherent and antibiofilm activities were evaluated. The growth of gram-positive but not gram-negative bacteria was inhibited to different extents by these compounds. An extract of hop cones containing 51% xanthohumol was slightly less active against S. aureus strains (MIC range 31.2-125.0  μg/mL) than pure xant...

Hops (Humulus lupulus L.) is a species that grows spontaneously in Corsica, but the characterization of this territory has not yet been investigated. The main objectives study are to explore features wild hops from Corsica and determine effect island terroir on some cultivars first year growth. A multidisciplinary approach consisting genetic analysis, morphological comparison chemical essential...

Diante da crescente expansão área e produção de lúpulo no Brasil, o objetivo deste trabalho foi estimar a temperatura basal inferior (Tb) para surgimento nós, caracterizando crescimento cultura em uma região clima tropical. A pesquisa realizada experimental Escola Superior Agricultura “Luiz Queiroz”, Piracicaba, SP. Para experimento foram utilizadas sete plantas (var. Cascade), conduzidas vasos...
