Effects of cold stratification and H2SO4 pre-treatments on germination of sea buckthorn (Hippophae Rhamnoides L.) seeds under open field and greenhouse conditions
(Parlar Scientific Publications, 2017)
This study was carried out to determine the effects of some pre-treatments including soaking in concentrate (96%) H2SO4 for 1, 2, 3 and 4 minutes and cold stratification for 10, 20, 30, 40 and 50 days on seed germination ...
A modified ridge m-estimator for linear regression model with multicollinearity and outliers
(Taylor & Francis Inc, 2018)
The ordinary least-square estimators for linear regression analysis with multicollinearity and outliers lead to unfavorable results. In this article, we propose a new robust modified ridge M-estimator (MRME) based on ...
Effects of fire intensity and slope on surface soil erosion following a prescribed fire in old pinus nigra stands
(Parlar Scientific Publications, 2017)
As a practical forest fuel-reduction technique,
prescribed fires have been implemented in many
countries regardless of their potential impact on surface soil erosion process. Greater runoff and surface
soil erosion (rill ...
Gully and streambank erosion and the effectiveness of control measures in a semi-arid watershed
(Parlar Scientific Publications, 2018)
Quantifying the sedimentation contributed by different erosion pathways, including rill, interrill, and gully and streambank soil losses at the watershed scale is crucial to know for adopting the best management practices ...
Abscisic acid cross-talking with hydrogen peroxide and osmolyte compounds may regulate the leaf rolling mechanism under drought
(Springer Heidelberg, 2018)
Leaf rolling observed in some crops such as maize, rice, wheat and sorghum is an indicator of decreased water status. Moderate leaf rolling not tightly or early increases the photosynthesis and grain yield of crop cultivars ...
Preparation and characterization of high-performance wood polymer nanocomposites using multi-walled carbon nanotubes
(Sage Publications, 2017)
Effect of industrial grade multi-walled carbon nanotubes on mechanical, decay, and thermal properties of wood polymer
nanocomposites was investigated. To meet this objective, pine wood flour, polypropylene with and without ...
Cypsela micromorphology and anatomy in Cirsium sect. Epitrachys (Asteraceae, Carduoideae) and its taxonomic implications
(Wiley, 2017)
Cirsium Miller, one of the largest genera of the Asteraceae (Carduoideae), contains more than 250 taxa. Turkey is one of its diversity centers and according to recent studies this genus is represented by 80 taxa. In the ...
Entomopathogenic fungi isolated from thaumetopoea pityocampa and their efficacies against its larvae
(Parlar Scientific Publications, 2017)
Thaumetopoea pityocampa (Den. and Schiff.) (Lepidoptera: Thaumetopoeidae) is an important pest of pine trees in central and southern Europe, including Turkey. This study was conducted in Samsun Province in the Black Sea ...
Robust Liu-type estimator for regression based on M-estimator
(Taylor and Francis Ltd., 2017)
The problem of multicollinearity and outliers in the dataset can strongly distort ordinary least-square estimates and lead to unreliable results. We propose a new Robust Liu-type M-estimator to cope with this combined ...
Leaf size variation in natural wild cherry (prunus avium) populations in Turkey
(Friends Science Publishers, 2018)
Variation in leaf size in relation to population location was investigated in 25 natural wild cherry (Primus avium L.) populations in Turkey. A total of 25 populations were identified across Turkey. In each population 20 ...
