    EFECTELE TEMPERATURII RIDICATE LA DIFERITE ETAPE ONTOGENETICE ASUPRA UNOR INDICI FENOTIPICI LA PLANTELE DE TOMATE

    The study aims to investigate the tomato plants response to heat stress applied at the germination and seedling stages, evaluating certain phenotypic parameters in order to highlight possible particularities associated with adaptability to unfavorable environmental conditions. The research included three tomato genotypes with determined stress reactions that were designed into four variants: optimal-optimal, optimal-stress, stress-optimal, and stress-stress. The application of high temperatures at the germination stage significantly affects the subsequent development of tomato plants, resulting in a decrease in the average values of morphological traits compared to optimal conditions variants. The effects of heat stress vary depending on the genotype and the analyzed trait, with certain variants exhibiting specific vulnerabilities. Variance analysis shows that the temperature conditions and the stress application scheme significantly contribute to the variability of morphological traits, with stress at the germination stage having a dominant impact on architectural traits of plants, while genotype becomes the major influencing factor at the seedling stage. The results emphasize the importance of plant adaptability to thermal stress at different developmental stages.

    NOI SOIURI DE USTUROI CU ADAPTABILITATE SPORITĂ LA SCHMBĂRILE CLIMATICE
    (CEP USM, 2023) Botnari, Vasile; Chilinciuc, Al.
    Despite the centuries-old traditions of garlic cultivation, and the systemic perpetuation of a series of problems related to the maintenance and evaluation of the gene pool, mainly of local forms as safe sources of resistance to biotic and abiotic factors and their inclusion in the improvement process in order to create new varieties, complimented with the study of biological peculiarities and cultivation technology, the production of planting material still remains unexplained. In order to ensure scientific assistance, the creation and implementation in culture, collections and contest nurseries were developed, created and approved 4 varieties of garlic with high and stable productivity, increased resistance to environmental factors, Updating the technological parameters of cultivation for different production conditions would contribute to raising the efficiency and production level of the given crop.
