Molecular phylogenetic analysis of archival tissue reveals the origin of a disjunct southern African-Palaearctic weevil radiation
(Wiley-Blackwell, Hoboken, 2013)
Aim We test three alternative hypotheses for the disjunct Mediterranean-southern African distribution of endophagous weevils within the genera Rhinusa and Gymnetron (Coleoptera: Curculionidae): (1) a Palaearctic origin ...
PCR-RFLP-based method for reliable discrimination of cryptic species within Mecinus janthinus species complex (Mecinini, Curculionidae) introduced in North America for biological control of invasive toadflaxes
(Springer, Dordrecht, 2013)
Several populations of the stem-mining weevil Mecinus janthinus Germar species complex (Mecinini, Curculionidae), identified based on morphological characteristics, have been introduced in North America for the biological ...
Plum sectorial resistance to Plum pox virus is graft transmissible
(Budapest : Akadémiai Kiadó, 2013)
Graft transmissibility of the plum sectorial resistance to Plum pox virus (PPV) was investigated. Sectorial resistance is the resistance which is manifested in a sector or portion of infected plant, where virus is not ...
The effect of IAA producing Bacillus sp. Q3 strain on marshmallow seed germination
(Scientific Issues Natl Centre Agrarian Sciences, Sofia, 2013)
Marshmallow (Althea officinalis) is one of the important medicinal plants in Serbia. One of the bigest problem in growing of marshmallow is poor seeds germination. Rhyzospheric bacteria able to produced plant growth ...
Identification of Two Cryptic Species Within the Praon abjectum Group (Hymenoptera: Braconidae: Aphidiinae) Using Molecular Markers and Geometric Morphometrics
(Oxford Univ Press Inc, Cary, 2013)
The genus Praon represents a large group of aphid endoparasitoids and is exemplary for the problems encountered in their taxonomy because of a great variability of morphological characters. To investigate the intraspecific ...
Identification and characterization of Agrobacterium spp. isolated from apricot in Serbia
(Springer, Dordrecht, 2013)
Crown gall, caused by tumorigenic strains of Agrobacterium spp., is considered one of the most important diseases in stone fruit nurseries throughout the world. Since the crown gall disease has not been studied extensively ...
Characterisation of benzimidazole resistance of Cercospora beticola in Serbia using PCR-based detection of resistance-associated mutations of the beta-tubulin gene
(Springer, Dordrecht, 2013)
A survey to detect and characterise benzimidazole resistance within populations of Cercospora beticola in Serbia was performed. From 52 field isolates collected from sugar beet and beet root, only eight were found to be ...
Lysiphlebus orientalis (Hymenoptera, Braconidae), a new invasive aphid parasitoid in Europe - evidence from molecular markers
(Cambridge Univ Press, Cambridge, 2013)
We report the occurrence of Lysiphlebus orientalis in Serbia, an aphid parasitoid from the Far East that is new to Europe and has the potential to become invasive. Our finding based on morphological characters is confirmed ...
Crop Response to Glyphosate Trimesium Sulphosate
(Univ Agr Sci & Veterinary Med Cluj-Napoca, Cluj-Napoca, 2013)
Glyphosate may cause injury to non-target plants. The first detectable symptom after glyphosate treatment is the growth inhibition, followed by noticeable yellowing (chlorosis) of the treated tissue. Five to ten days after ...
Stimulative influence of germination and growth of maize seedlings originating from aged seeds by 2,4-D potencies
(Elsevier Sci Ltd, Oxford, 2013)
Background: The 2,4-D (2,4-dichlorophenoxyacetic acid) is using as a growth regulator in tissue culture media. Maize seeds have poor ability to maintain germination rate in the long term. Objective: To examine the possible ...
