The paper highlights the importance and relevance of introducing economic studies to primary schools. research aimed investigate appropriate age, environment, type, composition presentation for combined knowledge. 190 students participating in were from three schools Hungary 10 classes. Given fact that case all significant results, a sufficient effect size could be measured, furthermore, releva...

The utilization of low-N tolerant and N-efficifent varieties offers significant benefits in terms reducing the need for excessive N fertilizer input. Quinoa, a resilient crop agroecological transition, possesses wide genetic diversity, making it suitable selecting genotypes that require less fertilizer. In this study, growth physiological characteristics nine quinoa were assessed to determine t...

Seashore paspalum (Paspalum vaginatum Swartz) is a perennial warm-season turfgrass which known for its superb salinity tolerance. Compared to bermudagrass, seashore exhibited the adverse character of faster vertical growth, wider leaf, weak cold-, drought- and disease-resistance. In this study, we aimed improve these unfavorable traits through strategy callus irradiation. The results showed tha...

In order to select the mischarging mutants of Su+2 glutamine tRNA, auxotrophic amber mutants of E. coli K12 which cannot be suppressed particularly by Su+2 were screened. By utilizing these mutants, cysam235 and metam3, several tens of mischarging mutants of Su+2 were isolated, as those conferring altered suppression patterns for a set of tester amber mutants of bacteria and phages. Nucleotide ...
