نفذ هذا البحث في المشتل التابع لجامعة تشرين و في مشتل الساحل التابع لمديرية الزراعة باللاذقية. أظهرت النتائج تفوق صنف الكمثرى "Cocia" المطعم على أصل الكمثرى السورية معنوياً على صنف الكمثرى "Williams" و صنف السفرجل "صيداوي" المطعمين على الأصل نفسه، حيث بلغت نسبة نجاح التطعيم للأصناف الثلاثة في العام الأول (100% ، 90% و 66.67%) على التوالي . و في العام التالي (93.33%، 76.67% و 53.33%) على التوالي. و أشارت النتائج إلى وجود درجة توافق جيدة بين الصنف "كوشي" و الأصل المستخدم مقارنة بالصنفين الآخرين. كما بينت نتائج التحليل الإحصائي تفوق الصنف "كوشي" على الصنفين " وليامز" و "الصيداوي" من حيث الزيادة في ارتفاع المطاعيم، و تفوق الصنف "وليامز" على الصنف "الصيداوي" و هذا يؤكد بأن الصنف "كوشي" يعتبر متوسط قوة النمو عند تطعيمه على أصل الكمثرى السورية، بينما الصنف "وليامز " فيعد مقصر في قوة النمو ، و الصنف "الصيداوي" مقصر جداً عند تطعيمهما على الأصل نفسه ، خاصة في السنوات الأولى من تطعيم الغراس.
This research was conducted in seedling area belonging to Tishreen University and in the Coast seedling belonging to Agricultural Directorate in Lattakia. Results has shown that, the pear variety Cocia grafted on pear Syrian rootstock was significantly better than pear variety Williams and Quince variety Saidawi grafted on the same rootstock, where the percentage of grafting were 100%, 90% and 66.67% consequently, and in the next year 93.33%, 76.67% and 54.00% consequently. Results has shown a good agreement between a variety Cocia and a used rootstock in comparison with the tow other varieties. The results of analytical calculation has shown that, the variety Cocia was better than the tow other varieties Williams and Saidawi in graft-height, also, Williams variety was better than Saidawi variety, and this confirm that, the Cocia variety in medium growth when it grafted on pear Syrian rootstock, whereas, Williams variety was in poor growth and Saidawi variety was very poor in growth when they were grafted on the same rootstalk especially in the first years of grafting.

This research aims at studying the effect of irrigation with different levels of NaCl on
the growth and development of Syrian pears (Pyrus syriaca). The results showed that:
1. Salt stress reduced chlorophyll content (a,b and a+b) in salt treatment
s compared to
the control , which contained 67.48 mg/g (a), 111.62 mg/g (b) and 204.76 mg/g (a+b),
while 1750 ppm of NaCl treatment contained 49.34 mg/g (a), 49.86 mg/g (b) and 158.77
mg/g (a+b) respectively. Treatment with 500 ppm of NaCl increased significantly
chlorophyll content compared to other salt treatments.
2. Leaves content of proline increased with increasing NaCl levels. It reached 870.8
ng/g when irrigation water contained 1250 ppm of NaCl, while it decreased in other salt
treatments. Leaves dry matter increased with the increase salt levels (24.50% for the
control, and 44.86% for 1750 ppm of NaCl).
This study was conducted on the type of the Syrian pear, Pyrus syriaca. Boiss spread wildly in the Qardaha area in Lattakia governorate during the years 2012-2013 AD. Nine phenotypic phenotypes scattered in different locations (Ain Al-Arous - Deir Hanna - Basin) were studied, where the results showed that there were differences in some traits out of 14 studied phenotypic traits.
A study was conducted on one type of Syrian pears ‘Pyrus syriaca. Boiss’ which is
widespread in Al-Qardahah area/Lattakia during 2012-2013. 9 superficial models were
studied, these are scattered in different locations (Ein Al Aaros , Derhana, and B
sin).
The results revealed the existence of differences in some of the characteristics, out of
13 morphological studied characteristics. A cluster analysis showed a division in the
studied models. Two main groups can be distinguished: the first group included the
following models (P1, P2, P3, P4, P5, P6), whereas the second group included the
following models (P7, P8, P9). These two main groups are further divided into 4 subgroups
which can be considered independent morphological Models.
The first main group contains the first and second subgroups with a similarity value
0.62. The first subgroup contains P1, P2, P3, P4, P5, and it is symbolized as A; while the
second subgroup contains P6 and it is symbolized as B.
The second main group contains the first and second subgroups with a similarity
value 0.77. The first subgroup contains P7, P9 and it is symbolized as C; whereas the
second subgroup contains P8 symbolized as D.
The research indicates that there is a difference in the seed germination percentage of
the studied models. The seeds and embryos of P9 gave the highest germination percentage,
while the seeds and embryos of P6 gave the fastest germination percentage.
This study was conducted for two successive seasons 2010 and 2011 in the
vine nursery in the governorate of Homs/Syria to evaluate the degree of
grafting success between the two partners to create graft combinations in early
stage of grafting and
to select the most compatible rootstock for our local
studied cultivars. Three grapevines of local cultivars (Halawani, Baladi and
Bayadi) were grafted on four different American rootstocks (Ru140, B41,
Fercal and SO4) using bench grafting by omega machine.
This research was carried out during 2014 - 2015 in Scientific Centre for Agricultural
Researches. This research aims to determine the effect of some biological and genetic
indicators on the success of Carob seedlings in nurseries by studying three
kinds of
grafting: Auto-grafting, Homo-grafting and Hetero-grafting. Rootstock aged one year and
resulted by two chosen genetic types, namely, SnobarJablah and Alhafa were used. Scions,
they were taken either from seedlings with age of one year resulted by these two types or
from branches aged one year from the selected two types as well. Grafting was conducted
by using Whip Graft way in spring.
Auto-grafting has indicated the importance and the role of biological and genetic
factors for grafts and their impact on rates of grafting success. Concerning rates of success,
the results have shown that Auto-grafting surpassed Hetero-grafting with a significant
reference for both of two genetic types, regardless if the used scion was young or old.
In addition, Auto-grafting has shown surpass on other kinds of grafting, in terms of
subsequent growth of scions. On the other hand, a variety in biological indicators values
has been noticed between the two genetic studied types. In favour of SnobarJablahtype
againstAlhafaʼs type. However, the differences of values were not significant for the most
of conducted measures.
As for the age of scions, the results have pointed out that values of Hetero-grafting
with young scions surpassed values of Hetero-grafting with old scions in terms of the rate
of grafting success and values of biological studied indicators.
