Allelopathic Potential of Jasminum Officinale on Weed Species
Allelopathy is generally defined as any direct or indirect harmful or beneficial effect of one plant on another mediated by the production allelochemicals. The scope of this study was the evaluation of the potential allelopathic effect of Jasminum officinale against some weed species. The effects of extracts obtained from root, stem and leaves of J. officinale, were evaluated against ragweed (Ambrosia artemisiifolia), ryegrass (Lolium perenne), and Johnsonn grass (Sorghum halepense). The aqueous leachates of jasmine demonstrated promising allelopathic potential by inhibiting seed germination and radicle elongation of all tested species. The more profound research in the field of allelopathy will eventually lead to the development of bioproducts designed for pest or weed control using allelochemicals
Alternative Antimicrobial Formula for Plant Protection
The European Strategy regarding plant protection products encourages the research for solutions which strongly contribute to the agro-ecological transition. They should be able to provide effective and efficient products for both farmers and consumers, reducing the pesticides use. Previous studies reported that extracts prepared from different plant species are capable of inhibiting in vitro development of fungal phytopathogens. The aim of this research was the study of the antimicrobial activity of a plant protection formula composed by a mix of plant extracts. The final scope was establishing a proper treatment timing strategy for controlling primary infections. Therefore, the effectiveness of the mixed formula containing Humulus lupulus and Urtica dioica against Alternaria sp., the cause of early blight attacking several vegetable species, was studied. Experimentation plan was performed using standard methods for antimicrobial testing. The potential and limitations of plant extracts used to control early blight were discussed. The results obtained have potential practical applicability and are directed to the development of environmentally viable solutions for the design of bioproducts for plant protection. Better knowledge on this topic will help optimizing crop protection strategy, ensuring sustainable agricultural development
Employment and unemployment in the Bucharest-Ilfov region
This paper aims to achieve a study that consisted of research, analysis and interpretation of statistical data, in conjunction with theoretical aspects that allowed regional assessment of information on the structure of employment and unemployment in the Bucharest-Ilfov Region. Bucharest-Ilfov Region still remains the one with lowest ILO unemployment rate nationwide. It has fluctuated quite a bit in 2006-2010, around 4%, with the exception of 2008 when it fell sharply by almost a percentage to return a year later, value that increased in 2010 to 4.7; since 2011, it recorded an increase of 5.4% reaching 6.3% in 2012
