دُرس في المختبر تأثير درجات مختلفة من الحرارة، مستويات مختلفة من pH، فترات مختلفة من الإضاءة و أربعة مستنبتات غذائية هي (PDA، OMA، MEA،CzA) في نمو الفطر C.gloeosporioides المسبب لمرض الأنثراكنوز في ثمار الحمضيات، و أشارت النتائج إلى أنّ نمو الفطر كان أعظمياً في درجة الحرارة 30°م، و pH = (5.5، 6، (6.5، و أنّ الإضاءة غير ضرورية لنمو هذا الفطر . أعطى المستنبتان PDA ، OMA من بين المستنبتات المختبرة أقصى نمو للفطر C.gloeosporioides.
Effect of different degrees of temperature, different levels of pH , different periods of light and four media (PDA, OMA, MEA, CzA) was studied in vitro against the growth of C. gloeosporioides causing anthracnose disease of citrus fruits. The results indicated that the growth of fungus was maximum at temperature 30°C and at pH = (5.5,6,6.5), and Light was unnecessary for the growth of C. gloeosporioides. Among the different media tested PDA and OMA supported the maximum growth of fungus.

hybrid commercial chicks (Hubbard Flex) were A total of /450/
reared from 1 to 42 days of age. Chicks were distributed into five
groups; each group contained 90 birds within three replicates. Five
diets were used; the first was the traditional die
t (control group) and
the others differed in the growth promoters added and were as
following: nutritional antibiotic (Lincomycin) for the second group,
probiotic (Bacillus subtilis) for the third group, prebiotec (manna
oligosaccharide) for the forth group and finally a mixture of organic
acids for the fifth group.
The experiment was done within -2014 in plant physiology lab.of agriculture faculty
of Tishreen University for estimation of high temperature stress toleration of citrus leaves
in three varietis(Citrus Unshiu , Meyer Lemon,Citrus SinensisWashington
). Many random
samples of leaves were gathered from the foliage of the examined categories whereas tha
average of the taken leaves was 200 from the whole sides for each one tree from the
branches which are one year old . which were put for limited duration in a water bath about
many different degrees of temperature then they were put in water and then in a solution of
HCL acid .
Many references were studied of containing :non spotting on leaves ,which means
they are un harmed,simple spotting,the spotting of more than half of the leaves area,the
perfect leaves spotting.
Studied temperature were as the following :40-50-60-70-80.Each one of this
mentiond temperature,40 leaves were used .The statistics analys were done with the way of
Genstat 12,for the comparison between averages for the sake of calculating the least
significant difference at the guidance level :5% .
Studies showed that Satsuma leaves are the most toleration for high temperature,next
Citrus SinensisWashington is less than Satsuma.At last Meyer Lemon was the least .
The effect of some essential oils taken from Cinnamomum zeylanicum, Citrus
limonum and Rosmarinus Officinalis was investigated in relation to the growth of bacteria
Paenibacillus larvae which causes American Foulbrood disease that affects world hon
ey
bees Apis mellifera L. The study was carried out in the laboratories of the Faculty of
Agriculture, Damascus University from 2012 till 2013. This is in order to contribute to
preparing an integrated pest management program for American Foulbrood disease. The
oils were extracted from the plants using steam distillation. The effects of the
concentrations of oils on the growth of P. larvae were tested between (3.90625 - 500
μg/ml) using agar disc diffusion in petri plates. Results showed that the essential oils used
stop the growth of P. larvae in some of their concentrations. The minimal inhibitory
concentrations which stop the growth of P. larvae of the oils of Cinnamomum zeylanicum,
Citrus limonum and Rosmarinus officinalis were recorded at 31.25 μg/ml, 62.5 μg/ml, 125
μg/ml respectively.
This study was performed in order to determine the temperature
rise under human dentin discs of different thicknesses of primary teeth
during the light curing process with conventional halogen lamp and
LED.
Effect of Citrus trestiza virus (CTV) in Growth of Balady common orange and
Satsuma trees grafted on sour orange Rootstock in Hraisoon during 2013 was studied. The
results showed that of infection by CTV caused deformation of shaped leaves, boat or
spoon-shaped leaves. The symptoms was greater in Satsuma from Balady common orange
trees. Also leaf size average of Balady common orange trees reduced from 15.58 cm2 in
healthy trees to 11.82 cm2 in infection trees as percentage 24.13, and from 19.64 cm2 in
healthy Satsuma trees to 12.38 cm2 in infection trees as percentage 36.97. and length
average of spring, summery and autumnal fresh foliages growths was reduced from 20.98
cm, 14.62 cm, 12.17cm in healthy Balady common orange trees to18.75cm, 12.52cm, 9.32
cm in infection trees respectively. Also it reduced from 18.78 cm, 14.56 cm, 10.06 cm in
healthy Satsuma trees to 13.78 cm, 9.34 cm, 6.03 cm in infection trees respectively, the
CTV had no significant effect on Trunk circumference in both varieties.
