    Primary diagnostics of drought resistance of wheat genotypes under osmotic stress
    (CEP USM, 2024) Platovschii, Nicolai; Zdioruk, Nina; Calugaru-Spataru, Tatiana
    The primary drought resistance of wheat plants of Moldavian and Ukrainian selection to induced drought caused by different sucrose solutions (3, 5, 10, and 16%) was studied. Testing of six wheat genotypes from Moldova and Ukraine revealed a distinct distribution of seed germination rates at sucrose concentrations above 16%. Genotypes showed a sharp response in root development to 3% and 5% sucrose compared to aboveground parts. These reactions of the root system can allow the classification of genotypes according to drought tolerance. This method provides an effective tool for the early selection of drought-resistant genotypes, supporting sustainable wheat cultivation under water stress conditions.

    REACTION OF EUROPEAN BEECH SEEDLING LEAVES TO HEAT SHOCK
    (CEP USM, 2023) Zdioruk, Nina; Sfeclă, V.; Platovschii, Nicolai; Ralea, T.
    Heat shock is considered an abiotic stress for plant growth. The effect of heat shock of various intensity on the leaves of the seedlings of the European beech (Fagus sylvatica L.) was studied. The seedlings were obtained from the seeds which were collected from different regions of the Republic of Moldova, Romania and Ukraine. The magnitude of the damage dealt to the photosynthetic apparatus was determined by the method of PAM - fluorimetry. The experiment was carried out during the period when 4–5 true leaves appeared in beech seedlings at a heat shock temperature of +50 and +52°C.

    ACTIVITY OF FS 2 IN FLAG LEAF AND DEPTH OF THE TILLERING NODE TRITICUM AESTIVUM L.
    (CEP USM, 2023) Platovschii, Nicolai; Zdioruk, Nina; Ralea, T.; Gore, A.
    With the help of BAS Reglalg, it possible to control the depth of the tillering node in the soil. It was found that the experimental variants had higher levels of PS2 flag leaf activity compared to the control variants. In the heading phase, the activity of PS-2 of the flag leaf is the highest. The use of Reglalg contributes to the preservation of PS-2 activity during the period of intensive aging of the leaf blade, this affects the duration of the accumulation of dry matter of seeds in the ear, delaying the death of the leaf by about 1-2 days.
