morphological and pomological features were studied for two consecutive years in wild apricot seedlings grown under macedonian environmental conditions. the population comprised of 19 seedlings, i.e. genotypes, that showed notable fruit and tree traits. their flowering time and desirable fruit quality features were determined in comparison with ‘hungarian best’. in all genotypes, flowering occu...

This paper describes two new species of Eriophyoidea associated with trees belonging to the order Rosales in the south-western portion of East Azerbaijan province, Iran, collected during a survey in 2011: Aceria lobolinguae n. sp. on Elaeagnus angustifolia L. (Elaeagnaceae) and Rhinophytoptus nemalobos n. sp. on Prunus domestica L. (Rosaceae). Additionally, Phyllocoptes abaenus Keifer on Prunus...

apricot (prunus armeniaca l.) is a species particularly prone to erratic fruit set, and its flower bud drop has been repeatedly reported in different cultivars and growing conditions. a number of potential causes have been explored, but a clear main cause remains elusive. in this study, fruit set was determined for 11 apricot cultivars (‘precoce de tyrinthe’, ‘feriana’, ‘beliana’, ‘priana’, ‘be...

Prunus armeniaca L., apricot, is a member of family Rosaceae bears deciduous tree [1]. Still its origin is unclear among the researchers. In olden times it was known in America, then started to cultivate [2]. It is assumed that it may have originated in Northeastern China close to the Russian border. According to Morikian ES [3] it was known to Armenians which is supported by the discovery of i...

Self-incompatibility enables flowering plants to discriminate between self- and non-selfpollen. In Prunus, the 2 genes determining specificity are the S-RNase (the female determinant that is a glycoprotein with ribonuclease activity) and the SFB (the male determinant, a protein with an F-box motif). In all Prunus S haplotypes characterized so far, with the exception of Prunus armeniaca S(2) hap...

Flowering control is one of the several strategies for gene containment of transgenic plants. TERMINAL FLOWER 1 (TFL1) is known to be involved in the transcriptional repression of genes for inflorescence development. Two TFL1 transcripts with different 3' UTR were cloned from black cherry (Prunus serotina Ehrh.) using reverse transcription-polymerase chain reaction (RT-PCR) and rapid amplificat...

The effects of regulated deficit irrigation (RDI) were studied on 9 year-old apricot-trees (Prunus armeniaca L. cv. ‘Búlida’) grafted on ‘Real Fino’ rootstock. Two irrigation treatments were established. The first, a control treatment, was irrigated to fully satisfy the crop water requirements (100% ETc) and the second, a RDI treatment, was subject to water shortage during the non-critical peri...
