This research was conducted at the Faculty of Agriculture - Damascus University and the Public Authority for Agricultural Research in the period (2012-2013) and on the first two parts were used grape Salti for the manufacture of molasses and condense
d in two ways: the traditional way (to intensify under atmospheric pressure regulars) and the proposed method (intensify under vacuum ) was added limestone soil material (lime neighborhood) Pure article preliminary during the initial transactions according to the following levels: (0, 1.2%).
Field survey was conducted to identify plant nematode genera associated
with maize crop during the period August-October 2003. The study was carried
out at two locations: Kharabo station (Damascus countryside) and Al-Mraieh
station (Deir Al-zowr)
in Syria. 36 complex samples were collected from roots
and rhizosphere soil; nematodes were extracted by two methods Sieving and
Baermann funnel, examined under microscope for identifi cation. Population
density and absulute frequency for each genera were calculated. Results of field
survey showed the presence of 14 genera of plant parasitic, 4 fungivorous, and
12 omnivorous nematodes in maize roots and rhizosphere soil .
A study was conducted to investigate the presence of root knot nematode
(RKN) and other plant parasitic nematodes associated with Syrian most
important peach plantation areas. 126 soil and root samples were taken from
63 peach orchards of Ghuta, Z
abadani, Yabrod, Syrghaya and Kharabo at

At this study, two species of genus Equisetum L. have been recorded, that they were:
Equisetum telmateia L. and Equisetum ramosissimum Desf.
E. ramosissimum Desf. was recorded for the first time in Lattakia.
The morphological features were used to
separate two species: ( number of the scaly
leaves in the node area, shape of the sheath, and number of its teeth, number of the grooves
at the stem, length of the strobilus and its color, length of the lateral branches).
This study showed that: the spores had three coats, the exosporium rounded by the
spore like bars with a wide terminal that called: elaters.
Also showed obvious difference in measurements the strobilus and the shapes
of sterile and fertile stem.
