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...

Apricot (Prunus armeniaca) was a thriving tree crop in California during the first half of the 20th century, with nearly 100,000 A under production at its peak in 1926 Foytik [1]. Since that time, production acreage has declined steadily to its current level of approximately 10,000 A. Harvested apricot volume in California has averaged just over 54,000 T annually over the last three reported ye...

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...

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...

world apricot (prunus armeniaca l.)  production is increasing steadily due to breeding of new high yielding cultivars in different countries. more recently, breeding programs have been modified according to consumers’ demands and also improvement in resistance to diseases (sharka, monilinia etc.), frost damages, and determination of self-(in) compatibility. in this study, fourteen apricot breed...

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...

The experiment was established at private apricot orchard near Cacak (Western Serbia) during 2010 and 2011. In the present study we wanted to determine the physicochemical attributes, phenolics content and antioxidant capacity of three new Serbian cultivars (‘Aleksandar’, ‘Biljana’, ‘Vera’) grafted on Myrobalan seedlings. Results indicated that physico-chemical attributes significantly varied a...
