Medicinal plants, since antiquity, have been relevant due to their therapeutic properties, are widely used for the prevention and treatment of diseases. However, the growth and production of these plants are impacted by a notorious environmental stressor, salinity. In this sense, this study aimed to review the impacts of salinity on plant development, the deleterious effects of this environmental stressor on the production of medicinal plants, and the production strategies of these species in saline conditions. Areas with salt excess problems have been increasing all over the planet, mainly due to human actions such as inadequate irrigation management. Salinity impacts plants at different times, the first phase results from osmotic stress, while the second derives from the ionic toxicity of the salt constituents. In medicinal plants, saline stress causes damage from germination to changes in morphological characteristics, physiology, nutrient concentration, and productivity. However, in some species, exposure to moderate degrees of salinity was positive for medicinal quality, with an improvement in the constitution of the essential oil. Strategies for the production of medicinal plants in saline conditions are reported in the literature, such as the use of amino acids (such as proline and betaine glycine), salicylic acid, arbuscular mycorrhizal fungi, resistance inducing genes, and projected nanoparticles. These strategies may represent an option for agricultural production in marginal areas and with waters with higher levels of salts.

A condições ambientais que possibilitam o cultivo do meloeiro estão relacionadas, sobretudo, aos fatores climáticos, tais como temperatura, luminosidade, umidade relativa do ar e características do solo e, a junção dessas condições pode favorecer ao meloeiro aumentar a produtividade de frutos e qualidade comercial. A pesquisa teve como objetivo avaliar as condições climatológicas e verificar a viabilidade da produção de melão cantaloupe no município de Patos, região semiárida paraibana. Os dados meteorológicos utilizados foram obtidos no Instituto Nacional de Meteorologia (INMET), no período de 2000 a 2020, sendo os elementos meteorológicos avaliados às temperaturas máximas, medias e mínimas e umidade relativa do ar, confrontando-se os dados obtidos com os dados ideais para a produção do melão. instalações para seu cultivo.   Constatou-se que no município de Patos apresenta durante o ano temperaturas máximas acima das exigidos pelo melão em todas as fases produtivas, sendo que temperaturas acima de 35 °C, como ocorre nos meses de Outubro a Janeiro.

The culture of Cowpea (Vigna unguiculata L.) of wide adaptation of the various edaphoclimatic conditions of Brazil is of fundamental importance for the socioeconomic development of the north and northeast regions, however, the productivity can be limited by pathogenic agents, such as phytonematodes, belonging to the genus Meloidogyne. Due to this condition, the objective was to Almeida et al.; JEAI, 37(2): 1-9, 2019; Article no.JEAI.49328 2 evaluate the behavior of different varieties of cowpea against the parasitism of M. incognita. The reaction test was performed with inoculation of 5.000 eggs/juveniles in the region of the root. The experiment was carried out in a greenhouse, with a completely randomized design, with 14 varieties (Bastiãozinho; Mosqueado; Maravilha; Balinha; Garanhão; Sempre verde; Canapuzinho; Canapu branco; Paulistinha; Pujante; Canapu da Vagem Roxa; Rajado PE; Costela de Vaca e Setentão) with five replications. 60 Sixty days after inoculation, some agronomic characteristics and parasitism were evaluated. All varieties were susceptible to M. incognita, with RR > 1. However, the Paulistinha variety proved to be moderately resistant. Original Research Article
