Ten extracts with different polarity from two Iranian Artemisia species, A. armeniaca Lam. and A. aucheri Boiss, were screened for their antimalarial properties by in vitro   β -hematin formation assay. Dichloromethane (DCM) extracts of both plants showed significant antimalarial activities with IC50 values of 1.36±0.01 and 1.83±0.03 mg/mL and IC90 values of 2.12±0.04 and 2.62±0.09 mg/mL for A....

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...

Male sterility is defined as the deviant condition in normally bisexual plants when no viable pollen is formed (Frankel and Galun, 1977). Male sterility has been exploited as an effective tool to aid hybrid seed production in many crops. Using this trait, seed producers can transform one inbred from a planned hybridization into a “female” line, thereby ensuring seed of hybrid origin on the male...

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...

The purpose of this research is to facilitate the mechanical harvesting of apricots (Prunus armeniaca L.) for industry. A tractor-trailed harvester was built to catch the fruits detached from apricot (cv. Búlida) trees by vibratory systems. This machine is a low profile catcher that can move under the trees in high-density canopies where umbrella-type harvesters cannot. The trailer is able to w...

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...
