    Seleção de progênies de tomateiro (Solanum lycopersicum l.) tolerantes à salinidade

    Tomato is one of the most important vegetable crops in the world, representing a significant source of employment and income, mainly in Brazilian Northeast, where risks of soil salinity constitute limiting factors for good crop development. Breeding programs for selection of progenies that tolerate this abiotic stress are essential. Then, the objective of this work is to select salinity-tolerant tomato progenies. For the experiment, 400 plants of F3 generation, 400 plants of F2 generation, 60 F1 plants and 60 plants of each parent, that is, the IPA-7 and Yoshimatsu cultivars, totaling 980 plants; for the second experiment, 400 plants of F2 generation, 60 plants of F1 and 60 plants of each parent (Yoshimatsu and IPA-7), totaling 580 plants, at a high level of salinity, in four replications were evaluated. The experiment was carried out in pots for 30 days, with evaluations taking place during 20 and 30 days after transplanting. On evaluation for the first experiment, morethan 50% of generations at 20 days demonstrated that they are tolerant, already at 30 days only the Yoshimatsu genitor showed tolerance, where others were not tolerantg, with variations in notes. For evaluation of the second experiment at 30 days after transplanting, as in the first one, only Yoshimatsu genitor was tolerant and others demonstrated more than 70% of generations not tolerant to saline level. The selection of tomato progenies is indicated from 30 days after transplanting. Through the F2 and F3 generations, dominance of non-tolerant phenotype was observed, indicating that possible salinity tolerance genes are recessive. Through the inheritance study that indicated the action of another recessive gene combined with experimental conditions, it was not possible to select salinity-tolerant progenies.

    Uma questão de gênero: A evasão feminina nos cursos de ciências agrárias do IFAL- Campus Piranhas
    (INSTITUTO FEDERAL DE ALAGOAS - Ifal, 2023-12-14) Ventura, Ruth do Nascimento; Paiva, Monikely de Oliveira Silva; http://lattes.cnpq.br/0034233122382052; Silva, Michelangelo de Oliveira; http://lattes.cnpq.br/5831953262176334; Fireman, Ana Luiza Azevedo; Silva, Jailson Costa da
    Female dropout in secondary and higher education courses, especially in the area of Agricultural Sciences, is a phenomenon that generates concern and has been raising concerns for a long time, despite the increase in female presence in various areas of knowledge, women are facing challenges in this regard. field of science. Courses focused on Agricultural Sciences have a large male participation, which ends up reinforcing that agricultural activities are of interest and responsibility only to men. However, in recent decades there has been an increase in female participation in these areas, whether due to the search for greater professional diversity or the current perception of the importance of environmental management and sustainable development. There are many motivations that can lead to this regression, such as family issues, economic issues and even inspirations, in addition, many others are raised with regard to this topic, mainly in the context of inequality between genders in career pursuits and of opportunities that are little explored and discussed since a woman's childhood, whether within the family or more externally. Therefore, the objective of this work was to infer the reasons that lead students from agricultural courses (both technical and higher education) at an HEI in the interior of Alagoas to give up on academic life. The present study was developed at the Federal Institute of Education, Science and Technology of Alagoas (IFAL), on the Piranhas Campus. The research is qualitative in nature, descriptive in nature, where an explanation was made of the factors that lead to the regression of studies for female individuals, and is bibliographical, where texts and data were used to help understand the subject. The type of sampling used was non-probability convenience sampling. The questions were developed in the Likert style, being one of the most suitable for carrying out opinion research, developed in the United States in the 1930s and measuring the degree of compliance of the respondent with a statement, these are presented and the person interviewed issued the your degree of agreement with the sentence, among the answer options, are: 1) totally disagree, 2) disagree, 3) neutral, 4) agree and 5) totally agree. The factors listed for female dropout rates in Agricultural Sciences courses were issues related to the distance from the students' homes and adapting to their study routine, which becomes exhausting when combined with the route they travel every day. To discuss these points, one should not only focus on the problem itself, but on solutions that could be fundamental to reducing the number of female students dropping out of their respective courses. Therefore, consider the factors that make them believe that completing their course and continuing their academic life is crucial for their future. Techniques for integrating these students into the social and academic environment can help them stay and possibly help them resolve some type of problem faced outside the institution.
