Jerash for Research and Studies Journal مجلة جرش للبحوث والدراسات

This study was carried during 1998-2000 to evaluated six varieties of American and Asian durum ‎wheat belonging to the international group of Vavilov Institute for plant breeding (VIR), and ‎four European varieties in traduced under the conditions of the coastal area of Syria. These ‎varieties were compared with two local varieties in terms of important economic and ‎agricultural traits. The best variety will be selected for subsequent use in breeding programs ‎‎(Selection or Hybridization). A statistical analysis was performs, which showed significant ‎differences among varieties and between varieties and the control. Correlation and regression ‎analysis in addition to several other …

Water samples were collected monthly during 1999, from four sites, of different habitats. The ‎study revealed the existence of a total of 120 phytoplankton species, composed of 76 ‎Bacillarophyte, 37 Dinoflagellate, 3 Cyanophyte and 4 Chliorophyte species. Moreover, the ‎study also revealed considerable physio - chemical variations in their water, as well as ‎considerable variations in chlorophyll a. The physio - chemical variations of water, in the four ‎stations most likely is responsible for the variations of the phytoplanktonic species found in ‎them and their population densities.

In order to characterize the status and behavior of potassium in Iraqi soils thermodynamically, ‎twenty eight surface soil samples were collected from different locations to represent the ‎most dominant soil groups in Itrg (put thin names) Chemical, physical and mineralogical ‎characteristics were determined. The potassium forms of soluble, exchangeable, non - ‎exchangeable, mineral and elemental were determined. Thermodynamic parameters related ‎to potassium such as ionic strength, activity coefficient of potassium, activity ratio (K+: Ca2 + + ‎Mg2 +) and the free energy of replacement (DF) of K+: Ca2 + mg2+ were …


Isolation Of Proteins That Have The ‎Ability To Inhibit Potato Y Virus ‎‎(Pvy) Replication From Datura ‎Plants - Jimson Weed Datura ‎Strmonium, Raqeeb Al-Ani, Osama Al-Issawi, Shaalan Al-‎Mashaikhi Nov 2021

Two protein portions from Datura inhibiting the multiplication of PVY “were obtained by ‎filtration through sephadex G - 100. The first was maintained its activity at 60 с for 10 min; ‎whereas the other lost its activity at this temp. The SDS- polyacrylamide gel electrophoresis of ‎the heat resistant one revealed the presence of 8 polypeptides with molecular weights; 12000 ‎‎, 13000 , 22000 , 25000 , 29000 , 40000 and two other of smaller molecular weights . No ‎serological reaction was ovserced between these proteins and the antiserum of PVA, PVS, ‎PVM, PVX and PVY. No precipitate was observed …
