The research was conducted in plastic green house for the 2013-2014, in Alqangerh
village, about 5 Km from the city of latakia, in order to study the effect of spraying the
leaves with some humic compounds and amino acids on growth and production o
f hybrids
of cucumber (Novo,Dorruk).
Spraying leaves with three organic fertilizers are (Huzone, Mol mixs), and two boats
Dbalin and Amino vega (an amino acid).
The results showed that all treatments of leaves spraying with organic fertilizer geve
better resultus with significant differences than the control treatment in all the studied traits
of both hybrids: (stem length, number of branches/plant, number of leaves/plant, leave area
cm2, the number of flowers on the stem, number of fruits on the stem, number of floral
branches, number of fruits on the branches).The treatment of spraying achieved with
mixture of humic compounds and amino acids increase with significant differences in both
the number of leaves/plant, number of branches/plant, the plant's stem length and number
of fruit on the stem in the hybrid Novo. while the treatment of spraying achieved of hiozon
increase with significant differences the number of branches/plant, the number flowers on
the branches and number of fruits on the branches was in the hybrid Dorok. As for the
early production and total production, the treatment of spraying with mixture of humic
compounds and amino acids with significant differences on other transaction when both
hybrids Novo and Dorruk amounted, respectivety (5 ، 4,1 kg/m2 ; 16 ، 14,8 kg/m2 ).
This study was conducted in the Syrian coastal area to detect tomato seedlings
damping-off disease, to identify and isolate fungi responsible of the disease and to evaluate
their pathogenicity. Samples were collected from nurseries and greenhouses from four
locations (Jableh and Ras Elain from Lattakia and Hressoun and Majdalon Elbahr from
Tartous).
This investigation was carried out in a plastic house (350 m² area) located at Tishreen
University in two seasons 2007-2008 and 2008-2009, to study the effect of soil solarization
in soil borne fungi in greenhouse. With four treatments: the control
treatment,
Soilsolarization: 30, 40, and 50 days, and 0, 5, 10, 15 and 20 cm depth. The solarized soil
covered with transparent polyethylene.
The aim of this study is to examine the role of oxidative stress (OS) by measuring Malondialdehye (MDA) levels to test Lipid Peroxidation as a marker of oxidative stress in serum samples in toxic injuries resulting from exposure to anticholinesterase
insecticides (organophosphates and carbamates) in greenhouse workers in the coastal region of Syria. The study population comprised two groups (the majority of males): greenhouse workers who prepare and spray pesticides (100 workers, aged 18-61) and Control group (not never handle pesticides, 50 subjects, aged 19-58). Malondialdehye (MDA) levels were measured using enzyme-linked immunosorbent assay (ELISA). There was a significant difference in MDA levels in greenhouse workers group compared to control group (P˂0.05). Therefore, MDA levels could be considered as a biomarker for oxidative stress in greenhouse workers exposed to anticholinesterase insecticides and might be a useful diagnostic aid and monitoring exposure in those workers as well as cholinesterase enzyme.
Three identical gable-even-span greenhouses were designed, constructed
and installed at the Agricultural and Veterinary Research Station of King
Faisal University in order to produce cucumbers during the winter season.
These experimental greenhous
es were covered by ٠,٨mm thick fiberglass
reinforced plastic. Two different solar heating systems were designed, built and
employed to heat the ambient air temperature inside the greenhouses. The
design of the first one was a surface heating system suspended and fixed on the
southern side of the gable roof of one greenhouse. The second solar heating
system was a solar panel, which was designed, built and situated outside of the
other greenhouse.
