This investigation was carried out on fifteen years old Sorani and Kaissy
olive cultivars (Oleaeuropaea L.) trees grown in Basaltic soil that
was poor in organic matter and potassium.
The aim of the present investigation is to study the effect of
different
amount of organic and potassium fertilization on yield, fruit weight,
oil percentage, and oil acidity.
Results obtained showed that the highest value of fruit weight, yield, and
oil precentage exhibited statistically the highest values by trees
fertilized with the treatments (Organic + Potassium).
Acidity increased in (Organic + Potassium) treatments but it was less than
2% oleic acid , while it was less than 1% oleic acid in Potassium
treatments and in Organic treatments (Extra vergin oil).
In this
search we characterized 8 double purposes olive varieties (Mawi
Istanbuli, Khilkhali Khishen, Dan, Mniekri, Doaibli, Khilkhali
Saghir, Karamani Modabal, Sourani), which cultivated in ACSAD
Gene bank in Gellin by ISSR molecular markers to
determine the
relationship between these varieties, we noticed that these varieties
are so close to each others depending on quantitive traits, which
ranged from 60% and 85%, it was noticed that Mneikri was apart
from the other varieties in its traits, polymorphic rate was 92.94%.
Pathogenic germs have developed an increasing resistance toward many
antibiotics which form a true problem for human being ,because these germs can transport to him by
many ways such as water ,food and air that may cause many dangerous diseases to
human being.
The aim of this study is to investigate the effectiveness of extractions prepared from different parts of the
flowing plants: Olea europea Linn(Oleaceae) , Myrtus communis Linn(Liliaceae) ,Majorana syriacus
Linn (Laminaceae), Zingiber officinale Linn(Zingiberaceae),and Achillea falcata Linn(Asteraceae), against
Pseudomonas Aeruginosa.
This experiment was carried out during 2009 and 2010 seasons in fields
cultivated with 10 years of Dan and Nebaly cultivars of olive trees in province
of Damascus to study the effect of foliar spray of to one of nitrogen (N), boron
(B) and zinc (Z
) on the leaf area, shoot length, number of flowers, leaves
content of mineral elements, fertilization. These elements were sprayed
individually or combined together four times during the growing season as
follows: nitrogen (5 g/l), boric acid (2g /l), zinc sulfate (2g/ l), nitrogen + boric
acid, nitrogen + zinc sulfate, Boric acid + Zinc sulfate, and nitrogen + boric acid
+ zinc sulphate) at the same rates in single spray.
Alternate bearing is one of the most important phenomena in the olive trees.
A study was conducted during 2002 - 2003 at the Agricultural Research
Center in Homs on two olive varieties (Sorani and Daebli) to assess the effect of
flower and fruit t
hinning at different time intervals on flowering
differentiatian, percentage of vegetative buds, length of branch, length of the
internodes and total number of buds. The results showed that:
- flower thinning and treatment with Gibberellic acid (GA3)
during the maximum flowering did not influence the percentage of
buds, while flower thinning during different periods folowed by
treatment with Gibberellic acid during the fruit setting phase,
endocarp sclerification had significantly decreased the percentage of
flower buds for Sorani variety in 2002 and 2003 during the fruit setting
phase and two weeks later.
In Daebli variety this treatment decreased the percentage of flower buds
during fruit setting, two weeks later, and after four weeks from fruit setting
whereas, the treatment had not effect in both the varieties during endocap
sclerification stage.
Verticillium wilt is one of the most serious disease that affect olive trees, and it is
spread all over the world where the olive trees grown. It is caused by the soil – borne
fungiVerticilliumdahliaekleb. Whichhas a wide host range, and forms amic
roseclerotia that
survive for long time in the soil.and it is difficult to manage.
In this studya survey was carried out in order to determine the incidence and severity
of infection on olive trees in Lattakiaduring2015.
The results showed that the highest percentage of infection and severity were on the
Kaissicultivar in ALqurdaha (10.68% , 4.05%) respectively , and the lowest percentage of
infection and severity were on the Safrawicultivar in ALqurdaha (3.92% , 0.97%)
respectively.
The research aims to study the economic efficiency of olive mill wastewater
(OMWW) use in fertilizing olive trees, Which included research sample / 294 / farmer in
Lattakia Governorate, depending on the descriptive analytical method,And found the
results to be to fertilize the olive trees with (OMWW) rents high productivity, Where it
posted a net profit of (33,668) SP / acre / year, while gross margin stood at (61 235) SP ,
The coefficient of profitability compared to the cost of production (about 41.32%)%, while
the profitability coefficient was compared to the capital invested approximately 42.98%.
We discussed the importance of studying the trichomes award in
olive trees, leaves and its role in the resistance to these trees against
pollution resulting from the Banias refinery intake, through the
study of their density and distribution on a
superficial paper and
examine the concentration of chlorophyll in the leaves, and
comparing the results between the contaminated areas and the
control area .
Results showed that the density of the trichomes play a role in
protecting the ports of entry into force of pollutants into the plant
tissue, and its impact on the pigments of photosynthesis, and thus
the process of photosynthesis.
This research was carried out during the years (2010 – 2014), in
order to study the vigour for trees of six wild olive types which were
selected from the natural forest (In situ) in Moseif region, and the
vegetative rooted cutting at 4 years old in the nursery (Ex situ) in
comparison with The variety Al Safrawi.
in this study a land suitability evaluation was carried out for Olives
(Olea europancae ) cultivation and was performed in Latakia province.
it included 6 land units (coastal plains, valleys and river bed, summit,
gently sloping, moderately slopin
g, steeply sloping) each unit was
represented by one representative soil profile and its characteristics
were matched with olive requirement by using LAMIS and gis to
identify suitability classes.
