A field experiment was carried out at Abi Jarash farm, Faculty of Agriculture, Damascus University, during the two agricultural seasons 2011-2012/2013-2014 in order to evaluate the performance of some oily varieties introduced from the safflower crop
(SON-4, SON5, PI133055, Local Witness, GILA) under the influence of environmental conditions. Prevalent in Damascus governorate during the spring and summer season (intensive) after harvesting the wheat crop) using two rates of nitrogen fertilizer (control - without adding fertilizer, and at a rate of 75 and 150 kg. ha - 1 pure nitrogen unit)
The objective of this research is to propagate Mentha puligium in
vitro, shoot tips and nodal explant were planted with 0.5-1 cm length
on MS (Murashige's and Skoog) medium with various concentrations
(0.5-1-2-3-4) mg/L of cytokinin BAP.
This investigation was carried out at the Laboratory of Biotechnology at
General Commission for Scientific Agricultural Research (GCSAR), during the
season 2010-2011. The aim of this research was to study the genetic diversity
among twenty individ
ual plants of seven species and to determine the degree of
genetic similarity using the technique ISSR (Inter Simple Sequence Repeats)
and 10 primers were used for this purpose. All primers proved their
effectiveness in showing polymorphism between the studied species, primers
gave a total 195 allele with a polymorphic percentage 100%. The number of
bands for each primer varied from a minimum of 12 bands for the primer
(ISSR-4) to a maximum of 27 bands for the primer (ISSR-862) in an average of
19.5 bands for each primer, cluster analysis and Dendrogram showed the
highest degree of genetic similarity between accession A.leucoclada1 and
A.leucoclada2 (0.64), while it was low between species A.leucoclada3 and
A.glauca2 (0.10). Results showed vast genetic diversity among the studied
species.
The research was performed by isolating some species of soil- fungi from agricultural soils
handling with different pesticides and fungicides. Where the following fungi were isolated:
Aspergillus niger (The isolates A1 and A2), Fusarium oxysporum (
The isolate F),
Trichoderma harzianum (The isolate T). Also F. solani (The isolate F7) and T. viride (The
isolate T.v) were used, whereas they were taken from high studies laboratory- Science
Faculty- Tishreen University at a previous search.
The research was conducted to assay the ability of the previous fungi to degradation a
number of pesticides, the insecticide "Dolan", the insecticide "Plantocide", the nematicide
"Vydate" and the fungicide "Bayfidan", through the effect of double dose of each
pesticides in the biomass of the studied fungi on PDB medium. In addition to analysis the
results residues of pesticides using Spectrophotometer, and evaluation the pH values.
This research concludes an determination of some Culicinae mosquitoes
distributed in south of Syria.
The study show that there are 14 species, 3 of them were recorded for the
first time in the study area, these 3 species were described, illustrate
d , and
distinguished from related species ,the seasonal reproduction and the habitat
types of these were studied .
(Culex perexiguus , Cx.sinaiticus , Cx.territans).
