Research summary
تناولت الدراسة تأثير مستخلصات خشب المسكة (Robinia pseudoacacia L.) على الفطريات المسببة لأعفان بذور القمح، ومقارنتها مع المبيد الفطري Vita Flo في المختبر والبيت البلاستيكي. تم استخلاص مستخلصات الإيثانول/سيكلوهكسان من الخشب العصاري والقلبي للمسكة، وتم اختبار تأثيرها على الفطريات Fusarium sp. و Aspergillus sp. و Alternaria sp. أظهرت النتائج أن مستخلصات الخشب القلبي كانت أكثر فعالية في تثبيط نمو الفطريات مقارنة بالخشب العصاري. كما أظهرت المستخلصات الخشبية فعالية في تحسين نسبة إنبات ونمو بادرات القمح المصابة بالفطريات في البيت البلاستيكي. تفوق المبيد الفطري Vita Flo على جميع المستخلصات في تثبيط نمو الفطريات وزيادة نسبة الإنبات والنمو. أوصت الدراسة بإجراء تجارب إضافية على فطريات أخرى وعلى محاصيل مختلفة لتقييم فعالية المستخلصات الخشبية.
Critical review
تعتبر هذه الدراسة خطوة مهمة في البحث عن بدائل طبيعية للمبيدات الكيميائية في مكافحة الفطريات المسببة لأعفان بذور القمح. ومع ذلك، يمكن توجيه بعض الملاحظات النقدية لتحسين الدراسة في المستقبل. أولاً، كان من الممكن توسيع نطاق الفطريات المدروسة لتشمل أنواعاً أخرى من الفطريات الممرضة للنباتات. ثانياً، لم يتم التطرق إلى التأثيرات البيئية المحتملة لاستخدام المستخلصات الخشبية على المدى الطويل. ثالثاً، يمكن تحسين تصميم التجارب الحقلية لتشمل ظروف زراعية متنوعة تعكس البيئات الزراعية المختلفة. أخيراً، كان من الممكن تضمين تحليل اقتصادي لتكلفة استخدام المستخلصات الخشبية مقارنة بالمبيدات الكيميائية التقليدية.

The results showed a variation in the ratio of dry material derived from wood
samples of (Robinia pseudoacacia L.). The dry matter weight was (432.23 mg) (716.95
mg) for each of the waterless wood and internal wood respectively.
It was found that
the most important fungi associated with wheat seed group are:
Fusarium sp. (36%) and Alternaria sp. (28%) and Aspergillus sp. (12%) and Rhizopus sp
(9%) and Penicillium sp (6%) and fungi are not defined by (9%).
It was found that the wood extracts from (Robinia pseudoacacia L.) varied in the of
the Almiceleom inhibition to the tested fungi growth (Fusarium sp. , Alternaria sp. and
Aspergillus sp.) in the nutritious environment according to the type of the extracts,
concentration and targeted fungi. The effect of the wood extracts has increased as the
percentage of the dry matter of the heart wood increased. The incremental heart wood
ratio increased inhibitory effect on the growth of fungi. On the other hand, the wood
extract gave of waterless wood less effect of Miceleom inhibiting on the growth of tested
fungi in general. The effectiveness of the mixtures Increased as heart wood concentration
increased. It has been Found from the data that there was difference in migraine
concentration of the heart wood extracts and waterless wood mixtures largely. the Extract
of the mixture wooden gave (10:10) the highest efficiency among the three tested extracts
on the fungus, where the EC50 values were less than 46.50, 84.66 and 131.54 ppm for each
of the fungus (Aspergillus sp., Fusarium sp. And Alternaria sp. respectively.
The effect of salinity and the treatment with fungicide on seed germination of Cupressus
sempervirens L. was investigated.
Five concentrations of salinity (0, 0.5, 1, 5 and 10%) were used. One part of the seeds was
treated with fungicides (Benomyl
), while the other part was germinated without fungicide
treatment. The results showed that seed germination was reduced by salinity, but the reduction was
more pronounced without fungicide and with salt concentration, the seeds didn't germinate at 5 and
10% NaCl.
Despite the decrease of germination indices with the increase of salt concentrations, the
statistical results didn't show significant differences in salinity concentrations and the control in
germination speed without fungicide, but they were significant with the fungicide. The statistical
results showed significant differences between the presence and absence of fungicide in all
treatments
This research was conducted at Tal Shnan village, located at the eastern of Homs
city, Syria during 2012/ 2013 growing season, using hard local wheat cultivar,
Sham 5, to study the effect of seed rates (120, 150, 180, 210 kg/ha), spray with
differ
ent parts of sorghum water extracts using different, and weeding on wheat
yield and weeds accompany with the crop.
The study was conducted to evaluate the efficiency of Pseudomonas chlororaphis MA342,
Serratia plymuthica HRO-C48K, Bacillus subtillis B2g, B. subtillis FZB27 to induce systemic
resistance in Tomato plants against Cucumber mosaic virus (CMV) under
greenhouse conditions.
Tomato seeds submerged in suspension of Pseudomonas chlororaphis MA342, Serratia
plymuthica HRO-C48, Bacillus subtillis B2g and B. subtillis FZB27 9×109cfu . plants emerged
from these seed were inoculated with CMV after 10 days of planting. The time of beginning
symptoms was recorded, Disease incidence, disease severity, area under disease progress curve
AUDPC, progress of infection disease degrees during the study period were calculated using
virtual symptoms . pyroxidas enzyme activity was determined, Some growth parameters such as
Plant height, foliage fresh weight, root fresh weight , foliage dry weight, root dry weight were
observed after 30 DAI. Results of this study showed that seed treatment with Pseudomonas
chlororaphis MA342, Serratia .plymuthica HRO-C48, Bacillus subtillis B2g, B. subtillis FZB27
significantly decreased the diseases incidence on treated and inculated plants which ranged
between 40% - 66.66% ,compared with un treated and inculated control 93.33% Without the
presence of significant differences between the bacterial treatments. significantly decreased the
diseases severity on treated plants which ranged between 45.53 %- 62.2% compared with inculated
and un treated control 88.86% .Without the presence of significant differences between the
bacterial treatments. Peroxidas activity on treated plants increased by Compared with untreated
plants. Seed treatments with bacteria significantly increased the plant growth. The plant height ,
fresh and dry weight of foliage, fresh and dry weight of root on treated plants were significantly
higher than those of inculated and un-treated plants according to LSD 5%.where bacteria reduced
the rate of stunting and the rate of decline mild and dry weight of foliage and mild and dry weight
of the root occurring due to infection with the Cucumber mosaic virus (CMV).
A research was carried out at Al-Sanouber research station in
Lattakia in 2013/2014 season ,The research included six treatments
with four replicates for each treatment. Six treatments used of
OMWW (0 , 10 , 20 , 30 , 40 , 50) l/m2. The OMWW has b
een
added 40 days before planting. Samples of soil have been taken
before adding OMWW, then after one and two months from
planting, and at the end of the season in order to make some
physical and chemical analysis and also to know the concentration
of some micro elements .
