خلال فترة تنفيذ البحث تمت دراسة عملية التوافق ما بين الأصل و كل من الأصناف المطعمة عليه، من خلال تحديد نسبة نجاح عملية التطعيم لكل من الأصناف موضوع البحث، كما حددت قوة نمو تلك الأصناف و حجم مجموعها الخضري. كذلك تمت مراقبة الغراس المطعمة و أخذت القراءات اللازمة ابتداء من فترة التطعيم في نهاية الصيف و حتى نهاية موسم نمو العام التالي.
The compatibility between the varieties and the percentage of budding success and the vigor and vegetative growth of these varieties were studied. The plants growth was monitored and all the required readings were taken from the beginning of budding at the end of summer until the end of the next growth season.

استخدم التسميد الورقي بمستخلص الأعشاب البحرية والخميرة والحديد المخلب بالأحماض الأمينية لتحسين بعض الصفات الفيزيولوجية والإنتاجية لشجرة الدراق صنف red heaven والتخفيف من ظاهرتي إزدواجية ثمار الدراق وإصفرار نقص الحديد.
Peach (Prunus persica Batsch) transplants cv. Dixired were sprayed three
times a season with three levels of urea (45% N) (2.5, 5.0 and 7.5 gm/ L), and
two levels of iron (10 and 20 mg Fe/ L) using chelated iron Fe-EDDHA
(6%iron), each alone or in
combination. Meanwhile the control transplants
sprayed with distilled water during 2006 and 2007 growing seasons, twenty
days intervals between each spray and another, the first spray is done at the
first week of May in both seasons. Results indicated that all spray treatments
with urea and iron each alone or with each other significantly increased leaves
N, K, Fe, chlorophyll and carbohydrate concentration, transplant leaves area,
shoots number, transplants height, main stem diameter and vegetative and root
dry weight. While leaves P concentration, significantly decreased with the foliar
spray with two concentrations of iron alone, or in combination with all
concentrations of urea. The best treatment was 7.5 gm urea/ L + 20 mg Fe/ L.,
which gave the highest means of all studied parameters, except leaves P
concentration, which were the highest mean of it was in the control treatment
at both seasons.
This investigation was carried out in the fields and laboratories of Pome and
Grapevine Department, GCSAR/Syria, on some apple varieties i.e. Richared,
Mutsu and Tourly Winsap to determine the optimal harvest date and its effect on
storability. Fr
uits were harvested in (16/9, 26/9, 7/10, 17/10 and 30/10) depending
on physical and chemical maturity indicators, and stored with the study of changing
in quality indicators and weight lost monthly. The results showed that the studied
varieties differed in their storability according to harvest date, Richared fruits in
26/9 showed long storage for seven months with weight loss of 4.9%, fruit firmness
6.4 kg/cm2, and 18.7% TSS. While the storability was six months for Mutsu fruits
which harvested in 7/10 with weight loss of 4.4%, and fruit firmness 6.1 kg/cm2,
and finally, Tourly Winsap fruits which were stored for five months in 7 and 17/10
harvest dates with fruit firmness 5.1 kg/cm2. Moreover, the three varieties were able
to storage for three months when harvested in 30/10 with weight loss of 3.3%, 4.4%
and 4.5% in Tourly Winsap, Richared and Mutsu respectively, which considered
as consuming maturity for these varieties. These results indicated to the various
storage periods according to fruits harvest time, and the storability, which assists
in regulating offer and demand, and providing markets with fruits for long period,
however harvesting at optimal time reducing the total weight loss, in addition to
high quality indicators.
The Peach flatheaded rootborder Capnodis sp. is the most important insect
which attack stone-fruits in Syria, Entomopathogenic fungi Metarrhizium sp.
and Paecilomyces sp. were isolated from larvae of Capnodis tenebrionis
(Coleoptera: Buprestidae)
attacking peach. This study was conducted to reveal
the pathogenicity of the two fungies against the neonate larvae of Peach
flatheaded rootborder, The two fungies were used in a concentration 106
conidia/ml, dipping the larvae in fungal suspension ,then it was put in apricot
branches by approximately 1 cm diameter, and mortality rates two weeks after
inoculation with the suspension of each of the fungi was 95% for Metarrhizium
sp. and 85% for Paecilomyces sp.
The research studied the compatibility of grafting on the pistachio
variety of Ashouri with three rootstocks (P. vera, P. Atlantica and
P. Khinjuk). This research was implemented in the nursery of the
agricultural department in Hama. The seedling
rootstocks were
budded in plastic bags at the beginning of June by T-budding. The results demonstrated that the variety of Ashouri which budded on the Ashouri and P. Khinjuk rootstocks excelled at the p. Atlantica rootstocks, The best average of succeeded graft of Ashouri variety budded on the Ashouri and P. Khinjuk rootstocks reached (73, 69.5 %). While the growth of p. Atlantica and P. Khinjuk rootstocks were stronger than Ashouri rootstocks. The length of Ashouri variety which budded on P. Atlantica and P. Khinjuk rootstocks was (47.36, 49.88 cm), and the diameter was (5.59, 5.67 mm).
