resUmen ácido giberélico en la germinación de semillas de Jaltomata procumbens (cav.) J. l. gentry. el objetivo del presente trabajo fue evaluar la aplicación de ácido giberélico (ag 3 ) en la germinación de semillas provenientes de frutos silvestres de Jaltomata procumbens (cav.) J. L. gentry. el ensayo se realizó durante los meses de julio-agosto de 2006. Los tratamientos utilizados fueron 0; 50; 100; 150; 200 y 250 mg/l de ag 3 con 12 y 24 h de remojo, mismos que fueron analizados bajo un diseño completamente aleatorio en arreglo bifactorial (tiempo de remojo y concentración de ácido giberélico). Las variables fueron: porcentaje, velocidad y periodo de germinación. según los resultados, el tratamiento 250 mg/l presentó un 87,0% de germinación con 1,7 plantas/germinadas/día en un periodo de 25,5 días; superior a los valores presentados por los demás tratamientos. se observó que el tiempo de remojo influye menos que la aplicación de ácido giberélico.Palabras clave: mazahua, "tomate de arena", giberelinas. abstract gibberelic acid and seed germinartion of Jaltomata procumbens (cav.) J. l. gentry. The objective of this work was to evaluate the effect of gibberellic acid (ga 3 ) on the germination of seeds obtained from wild fruits from Jaltomata procumbens (cav.) J. L. gentry. The test was conducted during July-august 2006. The treatments used were: dose of 0; 50; 100; 150; 200 and 250 mg/l of gibberellic acid, in combination with 12 or 24 h of soaking, analyzed as a completely randomized design in bifactorial arrangement (time of soaking and gibberellic acid concentration). the variables measured were percentage, speed and period of germination. according to the results, treatments of 250 mg/l of gibberellic acid induced 87% of germination, with 1,7 plants germinated per day over a period of 25.5 days, higher than any other treatment. The time of soaking influences seed germination less than the application of gibberellic acid.
Introduction. Preventive measures taken during periods of health crisis, specifically in pandemics, have consistently been associated with detrimental effects on mental health. Isolation and loneliness are indirect effects of these preventive measures. Given these premises, monitoring the behavior of the population in the face of these eventualities becomes important. Worry as an indirect measure of anxiety and stress enables one to recognize subjects who are vulnerable to phenomena of high uncertainty, since measures taken to avoid excessive contagion can have high costs for this population. This phenomenon has been consistently observed in other pandemics such as H1/N1 influenza. Objective. To determine the prevalence of worry and perceived risk of contagion in the Guadalajara population during the COVID-19 quarantine and to identify differentiating effects. Method. A total of 255 people from western Mexico (Guadalajara, Jalisco) voluntarily participated by answering the Penn State Worry Questionnaire (PSWQ) adapted to Mexican population. The average age of the respondents, aged between 18 and 70 years, was 31.71 (± 5.19). A total of 170 women and 85 men participated in the study. Results. 40.12% of the population scored high levels of worry, making them vulnerable to mental health conditions. Subjects favored the prevention of a contagion regardless of whether they were self-isolated. The only variable that had a differential effect was sex (p < .05), and there were no differences in educational attainment, occupational demandingness, and isolation between the groups. Discussion and conclusion. A preventive attitude was observed among the participants, and so it is important to implement strategies that will prevent mental health costs in those who express excessive worry to avoid saturating mental health services.
Academic achievement, measured with the grade point average (GPA), is a stable characteristic that has been associated with many sociodemographic and psychological variables; however, the relation of these variables with GPA has not been totally elucidated. The objective of this study was to perform an association of health, psychological and personal variables with GPA and non-verbal intelligence in low-academic performance population according to sex. We invited health sciences university students who had failed the same subject twice to complete a set of sociodemographic and psychological variables and a non-verbal intelligence test. The GPA, admission exam test and preparatory GPA were obtained. We included 124 students, and found that GPA was associated with non-verbal intelligence in women but not in men; in whom, having a job and having a romantic partner, were more correlated. In women, positive relations with others, emotion perception and weekly physical activity hours were marginally correlated with GPA; while in men, emotion regulation and self-motivation had a tendency of correlation with GPA. In addition, we found that non-verbal intelligence was associated somatization and the number of diseases in women. Academic achievement is regulated by different variables in each sex; therefore, intervention programs addressed by sex are needed to increase it.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
