The paper presents the results of research conducted during the years 2015–2020 and the analysis of the influence of changing climatic conditions during the year on plant development, the number of crops obtained from gooseberry, Josta, black currant, red currant and white currant. The average fruit harvest obtained for the studied species varies depending on several factors, especially on the species, variety and changing climatic conditions of the year. Among the studied species, the gooseberry is the most productive, followed by the hybrid Josta, the red currant, the black currant and the white currant. As a result, the analysis of the data obtained regarding the fruit production allowed us to establish that depending on the species, the harvest of gooseberry varied between 7.36-11.9 t/ha, on Josta between 4.7-8.2 t/ha, for black currant – 4.3-8.1 t/ha, red currant – 4.3-8.5 t t/ha and for white currant – 3.7-7.8 t/ha. The crop according to variety increases the harvest on gooseberry by 3.13 %, blackcurrant by 1.49%, red currant by 2.99 %, and the harvest of white currant is not influenced by variety. In the conditions of a favorable year (year 2015), high harvests were obtained for the black currant with 8.1 t/ha; in 2016 year for gooseberry with 11.8 t/ha, Josta – 8.2 t/ha, red currant – 8.5 t/ha, for white currant – 8.2 t/ha. In the conditions of an unfavorable year (year 2020 compared to 2016), the harvest decreased on gooseberry by 36.1%, Josta by 42.7 %, black currant by 46.9 %, red currant by 49.4%, white currant by 52.6 %.

The paper presents the results of the study carried out regarding the development of the phenological phases of plant development of some species of fruit bushes in the Central area of the Republic of Moldova (the period of bud break, flowering and fruit ripening). It was established that the phenological phases of the studied species: raspberry (Rubus idaeus), black currant (Ribes nigrum), red currant (Ribes rubrum) and white currant (Ribes niveum), gooseberry (Ribes grossularia L.), Josta (Ribes x nidigrolaria), blackberry (Rubus caesius L.), sea buckthorn (Hippophae rhamnoides L.), honeysuckle (Lonicera kamtschatica), blueberry (Vaccinium corymbosum L.), dogwood (Viburnum opulus L.), chokeberry (Aronia melanocarpa Elliott), rose hip (Rosa rugosa Thunb), most of them having an early start in vegetation, which coincides with March, flowering takes place in April, and ripening – in June–July. Exceptions are: honeysuckle, with the earliest vegetation (03–09.03), flowering between 30.03 and 26.04 and ripening fruits in the second half of May (19–25.05); raspberries enter vegetation later (09–21.04), bloom on throughout May, and ripening takes place staggered in June, remontant raspberry varieties begin to bloom in July and ripens staggered in August; blackberry, with the latest onset of vegetation and the latest flowering (18.05–04.06), thus avoiding late spring frosts. Ripening takes place in stages at the beginning of July.

În lucrare sunt prezentate rezultatele cercetărilor efectuate referitor la fazele fenologice de dezvoltare a plantelor de măceș la soiurile: Vitaminnîi VNIVI, Voronțovschi în perioada anilor 2016–2018. În urma cercetărilor s-a stabilit că desfacerea mugurilor s-a produs între 01.04 și 10.04, înflorirea – între 05.05 și 15.05, maturarea fructelor – între 10.07 și 18.07. Durata medie dintre fazele de dezmugurire şi înflorire a atins 36-37 de zile, iar dintre fazele de înflorire şi maturare a fructelor aceasta a variat între 61 și 64 de zile. Recolta maximă de 7,5 t/ha a fost obţinută în anul 2016 la soiul Vitaminnîi VNIVI, iar la soiul Voronțovschi II recolta maximă de 7,0 t/ha a fost obţinută în anul 2018. Masa medie a fructului de măceş la soiurile studiate a variat între 0,9 și 1,1 g. Recolta medie a fructelor de măceş la soiurile studiate a variat între 5,7 t/ha (soiul Voronțovschi II) şi 6,2 t/ha (soiul Vitaminnîi).
