Background: Despite the availability of cultivated food crops and processed food, a large part of the Moroccan population, more particularly the populations of rural areas, still depend on the traditional use of wild plants, which constitute an important component of their food system. However, there is a lack of information on these plants and their medicinal and pharmacological properties, this is why our study aims to detect the antimicrobial activity of certain wild edible plants.Methods: disc diffusion method was used to evaluate the antimicrobial activities of extracts of Mercurialis annua L, Papaver rhoeas L, Foeniculum vulgare Mill, Chenopodium mural L, and Scolymus hispanicus L against the bacterial species Staphylococcus aureus, Enterococcus faecalis, Escherichia coli, Pseudomonassp, and against the yeasts Cryptococcus neoformans, and Candida albicansResults: The results showed that the crudeextracts from all the plants studied showed more or less important antimicrobial activities on one or other of the pathogenic microorganisms tested, except for the extract of M. annua, which showed no activity against all microbial strains. The highest antibacterial activity was observed for Scolymus hispanicus L extract against Escherichia coli (diameter of the inhibition zone: Ø=9mm ), the highest antifungal activity was marked for Foeniculum vulgare Mill extract against Candida albicans (Ø=8mm), and the extract of Scolymus hispanicus L against Cryptococcus neoformans(Ø=8mm).Conclusion: These results reveal that, in addition to the role they play in the diet, the food plants studied have an additional biological value due to their bioactive compounds.Keywords: In vitroantibacterial activity; Antifungal activity; Food wild plants; crude extract, Morocco

<p>A cultura do morangueiro é severamente acometida por várias doenças, dentre elas o mofo cinzento, causado por <em>Botrytis cinerea</em> é considerada a doença mais severa na pós-colheita. Visando reduzir o uso de fungicidas sintéticos, vem sendo realizadas pesquisas propondo a utilização de métodos alternativos de controle de patógenos pós-colheita envolvendo a utilização de extratos vegetais, uso de biofungicidas e óleos essenciais. Assim, o presente trabalho teve como objetivo avaliar o potencial de diferentes extratos de própolis e plantas espontâneas no controle de podridão pós-colheita causada pelo fungo <em>B. cinerea</em> em morangos. Para avaliar a atividade antifúngica direta dos extratos etanólico de própolis e extratos aquosos de plantas espontâneas sobre <em>B. cinerea,</em> foi realizado o experimento <em>in vitro</em>, utilizando-se os tratamentos própolis verde 0,5%; própolis verde 2,5%; própolis marrom 0,5%; própolis marrom 2,5%; língua-de-vaca 10%; assa-peixe 10%; rubim 10%; tansagem 10%; testemunha (água). As medições do diâmetro das colônias foram iniciadas 48, 72 e 96 horas após a instalação do experimento. No experimento <em>in vivo </em>os frutos foram imersos nos tratamentos descritos acima. Após cinco dias avaliou-se a incidência e severidade da doença mofo cinzento e das doenças pós-colheita como antracnose e podridão de Rhizopus que apareceram no experimento. Utilizou-se o delineamento experimental inteiramente casualizado (DIC) com quatro e cinco repetições para o ensaio <em>in vitro</em> e <em>in vivo,</em> respectivamente<em>.</em> Os resultados mostram que os extratos etanólicos de própolis verde e marrom a 2,5% apresentaram <em>in vitro</em> e <em>in vivo </em>atividade antifúngica a <em>B. cinerea</em> e <em>Rhizopus nigricans,</em> respectivamente.</p><p align="center"><strong><em>Potential of propolis extracts and extracts etanol spontaneous plants aqueous in control of diseases of strawberry post-harvest</em></strong><strong><em></em></strong></p><p><strong>Abstract</strong><strong>: </strong>The strawberry crop is severely affected by various diseases, including gray mold, caused by <em>Botrytis cinerea</em> is considered the most severe disease in post-harvest fruit. To reduce the use of synthetic fungicides, has been carried out research proposing the use of alternative methods of control postharvest pathogens involving the use of plant extracts, use of biofungicides, essential oils among others. Thus, this study aimed to evaluate the potential of different propolis extracts and wild plants in the control of post-harvest rot caused by the fungus <em>Botrytis cinerea</em> in strawberries. To evaluate the direct antifungal activity of ethanolic extracts of propolis and aqueous extracts of wild plants of B. cinerea, the in vitro experiment was performed, using treatments propolis 0.5%; propolis 2.5%; brown propolis 0.5%; brown propolis 2.5%; control (water + alcohol 2%); cow tongue 10%; assa-fish 10%; rubim 10%; tansagem 10%; control (water). Measurements of the diameter of the colonies were started 48, 72 and 96 hours after installation of the experiment. Conducted the in vivo experiment in which the fruits of strawberry plants were immersed in the treatments described above. After five days we evaluated the incidence and severity of gray mold disease and post-harvest diseases such as anthracnose and Rhizopus rot appearing in the experiment. We used a completely randomized design (CRD) with four and five replicates for the in vitro assay and in vivo, respectively. The results show that ethanol extracts of green and brown propolis 2.5% presented in vitro and in vivo antifungal activity to <em>B. cinerea</em> and <em>Rhizopus nigricans</em> respectively.</p>

The most important harvested organs of crop plants, such as seeds, tubers and fruits, are often described as assimilate sinks. They play little or no part in the fixation of carbon through the production of sugars through photosynthesis, or in the uptake of nitrogen and sulphur, but import these assimilated resources to support metabolism and to store them in the form of starch, oils and proteins. Wild plants store resources in seeds and tubers to later support an emergent young plant. Cultivated crops are effectively storing resources to provide us with food and many have been bred to accumulate much more than would be required otherwise. For example, approximately 80% of a cultivated potato plant's dry weight is contained in its tubers, ten times the proportion in the tubers of its wild relatives (Inoue & Tanaka 1978). Cultivation and breeding has brought about a shift in the partitioning of carbon and nitrogen assimilate between the organs of the plant.
