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 ...
Determination of Conyza canadensis Levels of Sensitivity to Glyphosate Trimesium Sulphosate
(Friends Science Publ, Faisalabad, 2013)
Changes in leaf anatomy were examined in two S. African populations of Conyza canadensis of which one was presumed to be resistant (CCPR) and the other susceptible (CCS) to glyphosate. Glyphosate was applied to plants, ...
Description of a new relict eriophyoid mite, Loboquintus subsquamatus n. gen. & n. sp (Eriophyoidea, Phytoptidae, Pentasetacini) based on confocal microscopy, SEM, COI barcoding and novel CLSM anatomy of internal genitalia
(Springer, Dordrecht, 2013)
A new pentasetacine mite Loboquintus subsquamatus n. gen. & n. sp. was found living under scale-like leaves of 2-3 years old twigs of Cupressus sempervirens in Montenegro. This mite species possesses a number of morphological ...
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 ...
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 ...
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 ...
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 ...
Characterization and evaluation of two Bacillus strains, SS-12.6 and SS-13.1, as potential agents for the control of phytopathogenic bacteria and fungi
(Academic Press Inc Elsevier Science, San Diego, 2013)
Two strains of Bacillus sp., SS-12.6 and SS-13.1, showed very strong antibacterial and antifungal activity against phytopathogens. The PCR analysis showed that both strains have the genes for biosynthesis of iturin, ...
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 ...
