    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.

    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.
