Aim This study investigated the antifungal properties of aqueous extracts obtained from indigenous plants that grow spontaneously in the Northern Sahara of Algeria. The activities of these plants in controlling two fungal species that belong to Fusarium genus were evaluated in an in vitro assay. Materials and Methods Fresh aerial parts of four plant species (Artemisia herba alba, Cotula ciner...

A field experiment was established to evaluate quantitative changes in weed species prevailing a crop rotation and 30-year cereal monoculture. The subject of the study included cropping systems: a) rotation, b) First (1989–1992) second (1993–1996) focused on infestation winter triticale monoculture; third (1997–2000) fourth (2001–2004) wheat; fifth (2005–2008), sixth (2009–2012), seventh (2013–...

This paper analyses the behavior of a hardware implementation of Genetic Programming using Field Programmable Gate Arrays. Three crossover operators that limit the lengths of programs are analyzed. A truncating operator, a limiting operator that constrains the lengths of both offspring and a limiting operator that only constrains the length of one offspring. The latter has some interesting prop...

Electromagnetic field (EMF) causes fundamental alternations in biological systems. In this study, we studied the effects of EMF on physiological responses and secondary metabolites production SiO2 NP-treated Anthemis gilanica plants. The results indicated that improved plant growth by inducing chlorophyll carotenoid content, which led to enhanced biomass adventitious roots treatment activity an...
