    Influența portaltoaielor din grupa geneva asupra dezvoltării și fructificării pomilor de măr după primul an de plantare
    (CEP USM, 2024) Peșteanu, Ananie
    The investigations were carried out in the apple plantation of "Viorix-Agro" Ltd., in the spring of 2022. The trees, planted at a distance of 3.5x0.8 m and trained after the crown vertical axis, were grafted on rootstocks M9, G11 and G41 for Gala Nikangie cultivar and on rootstock G11 for Fuji King Grofn variety. The results showed that in order to obtain early apple yields and to maintain a rational relationship between vegetative macrostructure and yield microstructure, as well as to prevent soil fatigue in replanted land, it is recommended to use the vegetative rootstocks G11 and G41 in association with the perspective varieties.

    Studiul influenței razelor X asupra genotipurilor de soia
    (CEP USM, 2024) Malii, Aliona
    The analysis of the impact of X-rays on soybean plants revealed a negative correlation between radiation dose and survival rate. The optimal mutation induction doses are up to 200 Gy for the Laduța variety and Z3M10100 line, while for the Clavera variety, this dose is limited to 150 Gy. Each genotype demonstrated variability in response to X-rays, suggesting different levels of tolerance. The height of the plants significantly decreased with increasing radiation doses, highlighting adverse effects on development. Controls, with no exposure, showed 100% survival, thus emphasizing the need for caution in using radiation in breeding research.
