    Research on corn tolerance to drought and heat in the context of changing plant-soil-water-air relationships caused by climate change
    (CEP USM, 2024) Spinu, Angela
    The study in this thesis evaluated a set of maize genotypes (simple hybrids) in field and laboratory conditions with different hydric stresses in different localities using a welldefined drought index to identify higher resistance/tolerance traits to drought and heat with a direct impact on final production.

    Seceta-factor de risc sporit pentru agricultura convențională
    (CEP USM, 2024) Botnari, Vasile; Cotenco, Eugenia
    In most years, the territory of the Republic of Moldova is affected by drought. The poor harvests of recent years are more than 50% caused by drought, especially in the Southern Zone, where severe and extremely severe droughts prevail. The occurrence and intensification of atmospheric and pedological drought conditions contribute to the precipitation deficit on the background of the high thermal regime, reducing the productivity of agricultural crops. In the May July period in 2023 and 2024, the average hydrothermal coefficient on the territory of the republic was only 0.3-0.4, which corresponds to a very strong drought.

    PARTICULARITĂȚILE RĂSPUNSULUI GENOTIPURILOR DE TOMATE SUB ACȚIUNEA INFECȚIILOR VIRALE ȘI A DESCENDENȚILOR ACESTORA LA STRESUL ABIOTIC
    (CEP USM, 2023) Mării, Liliana; Andronic, Larisa; Smerea, Svetlana; Rudacova, Angela; Cherdivară, Ala; Rudacov, S.; Sahanovschih, Marionela
    The evaluation of some polyvalent biochemical indicators under optimal conditions and heat or drought highlighted specific aspects if these plants came from parents infected with Tobacco Mosaic Virus (TMV) or Tomato Aspermy Virus (TAV). Thus, depending on the genotype, in both infected plants and their descendants, the POX values were usually higher or lower than the control group. The origin of the plants (control, TMV, TAV) had the largest contribution in the variability of H2O2 and stress for POX, respectively 74,1 and 23,6 %, and the combinations of the factors genotype, stress and origin had a considerable impact on the H2O2 content.
