The researches were done between 2012-2013, many observation and assessments being carried out in strawberry field, on the incidence (F%), severity (I notes; I %) and damages degree (DD%) of diseases which affect the strawberries foliage: Mycosphaerela fragariae - leaf spot, Podosphaera aphanis - powdery mildew and Diplocarpon earliana - leaf scorch. Under the environment of South-central of Roumania, the most tolerant cvs. on the Mycosphaerela fragariae - leaf spot were: ‘Cambridge Favourite’ (GA%=0.00-0.06) and ‘Mira’ (GA%=0.00-0.86). As regard the behavior on the Podosphaera aphanis - powdery mildew attack, the most tolerant cvs. were ‘Cambridge Favourite’, ‘Onebor’, ‘Idea’ (GA%=0.00) and ‘Elsanta’ (GA%=0.00-1.70). The most tolerant cvs. on the Mycosphaerela fragariae - leaf spot were: ‘Benton’, ‘Mira’, ‘Idea’ (GA%=0.00) and ‘Cambridge Favourite’ (GA%=0.00-0.03). ‘Mira’ and ‘Onebor’ are still used in strawberry breeding

Hazelnut is an essential species for nut production worldwide; extensive orchard areas have recently been planted in Romania. To choose the best cultivars to be grown in the future, a study was done on the behavior of seven hazelnut cultivars in the eco-pedoclimatic conditions of the Bucharest area. 'Hall’s Giant', 'Tonda Gentile delle Langhe', 'Romavel', 'Red Lambert', 'Tonda di Giffoni', 'Tonda Gentile Romana', and 'Vâlcea 22' were planted in the Experimental Orchard of the Faculty of Horticulture within the University of Agronomic Sciences and Veterinary Medicine of Bucharest. The results presented the behavior of hazelnut cultivars detailing the number of branches per tree, according to their age, and annually for each branch, length, and total cross-section area were measured. The influence of cultivars on yield and fruit characteristics at the harvest moment was detailed. 'Romavel' and 'Vâlcea 22' had the fruits with the highest weight, more than 3.3 g/fruit, while 'Red Lambert' and 'Tonda di Giffoni' presented the lowest values. 'Hall’s Giant' was the most vigorous cultivar, and 'Vâlcea 22' the less vigorous. Interesting growth dynamics for each cultivar and all studied branches in the two experimental years were detailed. First and second-year branches had the highest TCSA growth rhythm, but that was not maintained for the third to fifth-year branches.

The study presents the behaviour of 28 apricot cultivars planted in 2017 in the Experimental Field of the Faculty of Horticulture within the University of Agronomic Sciences and Veterinary Medicine of Bucharest. The foreign cultivars grafted on Myrobalan 29C, Saint Julien A and GF 677, were planted at 4.5 x 1.5 m and 3.5 x 2.0 m for Parallel U and respectively, 3.5 x 2.0 m for Trident canopy. Trees vegetative growth was evaluated by analysing the trunk cross section, tree height, fruiting branches number and length. First fruit yield was heighted and the productivity index was calculated. The results show differences in growth correlated with the canopy, cultivars and used rootstocks. Correlations between analysed parameters are presented. As a conclusion, the differences between the two canopies, Parallel U and Trident, using different types of rootstocks show their influence on the annual vegetative growth and on apricot trees productivity. Some preliminary conclusions can be drawn regarding the advantages and disadvantages of using the two canopies in apricot orchards.

The present study aims to generalize cultivar-specific tree phenology responses to winter and spring temperatures and assess the effectiveness of the Tabuenca test and various chill and heat accumulation models in predicting bloom dates for a wide range of climatic conditions and years. To this end, we estimated the dates of rest completion and blooming and correlated them with observed bloom dates for 14 peach and nectarine cultivars that were evaluated in 11 locations across Europe (Greece, France, Italy, Romania and Spain), within the EUFRIN cultivar testing trial network. Chill accumulation varied considerably among the studied sites, ranging from 45 Chill Portions (CP) in Murcia-Torre Pacheco (Spain) to 97-98 CP in Cuneo (Italy) and Bucharest (Romania). Rest completion occurred latest or was not achieved at all for some cultivars in the southern sites in Murcia. Dormancy release happened earliest in Bucharest and Cuneo, sites where heat accumulation had a strong influence on the regulation of bloom time. Blooming occurred earliest in the moderately cold regions of Lleida (Spain) and Bellegarde (France), and 7-11 days later in the warmer locations of Rome (Italy) and Naoussa (Greece), suggesting that bloom timing is strongly influenced by delayed rest completion in these locations. The Dynamic Model resulted in both more homogeneous chill accumulation across years and better predictions of bloom dates, compared with the Utah, Positive Utah and Chilling Hours models. Prediction of bloom dates was less successful for low-chill cultivars than for medium- and high-chill cultivars. Further climatic and experimental data are needed to make estimates of the climatic needs of peach cultivars more robust and to generate reliable advice for enhancing the resilience of peach production under varying and changing climatic conditions.
