    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.

    LINII DE PERSPECTIVĂ PENTRU OBȚINEREA SOIURILOR DE TOMATE CU REZISTENȚĂ SPORITĂ LA AGENȚII PATOGENI
    (CEP USM, 2023) Sîromeatnicov, Iulia; Cotenco, Eugenia; Paladi, Dana
    The investigated researches were oriented towards studying the dynamics of development and evolution of diseases in tomato culture with the assessment of resistance comparative of plants to pathogens visualized in field conditions (Alternaria sp.; Stolbur disease mycoplasma and Tomato mosaic virus (TMV). The research results show us that the effects caused by the disease Alternaria sp., in tomato lines cultured by seedlings were contaminated with the percentage value of 68,7%, at the same time for the parental forms cultured by seeds this disease constituted maximum values of 89.1%. The difference between perspective lines and parental forms is 20.4%. The maximum size of the values obtained in parental forms exceeds by 21.6% the outlook lines for the Stolbur disease mycoplasma.

    EVALUAREA POTENŢIALULUI PATOGENIC ÎN COMBINAȚIILE HIBRIDE F1 DE TOMATE
    (CEP USM, 2023) Sîromeatnicov, Iulia; Cotenco, Eugenia; Paladi, Dana
    In the current paper is presented the pathogen depending on its nature, the character of appearance and spread to tomato plants. Climatic conditions during the growing season were relatively unfavorable for primary description and evolution dynamic manifestation and extension of the disease that affected some reproductive organs with phytopathological impact. Evaluation of complex research in field conditions, on characterization and evaluation of plant genetic resources by using various methods of improving the pathogenic form, the tobacco mosaic virus has demonstrated an increase in disease compared to parental forms and a decrease compared to F1 hybrid combinations.
