Apricot and peach are species with a short dormancy, being able to start growing season even in February; the resistance of the trees to frosts and late frosts during this period is reduced. The risk is even higher in the south-east of the country where the probability of thermal amplitudes is very high, both during February and March. Although it is an important phenomenon, the information’s of how to protect trees from frost are relatively limited. There is a need for information to support orchards owners to approach this issue. The purpose of this paper was to apply measures and methods to combat this phenomenon in intensive apricot and peach orchards, measures that contribute to "saving" fruit production.

RSFG Constanța is the owner of the mother stock for biological superior categories of peach, so in order to align us with the new legislative requirements, starting with 2016 it was introduced in the evaluation process for obtaining Prebase Candidate mother plants for cultivars to which is maintainer: ‘Catherine sel. 1‘, ‘Cecilia‘, ‘Florin‘, ‘Filip‘, ‘Iustin‘, ‘Mimi‘, ‘Minodora‘, ‘Monica‘, ‘Redhaven‘, ‘Southland‘, ‘Springcrest‘. The evaluation was performed in terms of authenticity based on the test of distinction, uniformity and stability, as well as in terms of phytoviral. The evaluation of the phytoviral status has been done visually, by the biological method and by the DAS-ELISA serological test. The following pathogen agents were identified: ACLSV, ApMV, PPV, PDV, PNRSV, ALV, PLMV, SLRSV, ACLR. The results highlighted the presence of PPV in ‘Cecilia’, ‘Redhaven’ and ‘Southland’ cultivars, PDV in ‘Florin’ and ApMV viruses in ‘Cecilia‘s peach plants. Healthy plants have been propagated.
