A Survey of Pepper Mild Mottle and Cucumber Mosaic Viruses on Pepper Crop in the Syrian Coast andTheir Transmissionin the Field through Seeds

A field survey of Pepper mild mottle (PMMV) and Cucumber mosaic (CMV) Viruses was conducted in some plantation areas in Tartous and Lattakia Provinces. A total of 1278 samples (782 from Tartous and 505 from Lattakia) were collected. Results of Tissue Blot Immunobinding Assay showed the presence of PMMV in 0.39% and CMV in 11.42% in the collected samples. The percentage of CMV varied in Tartous and Lattakia Provinces. In this study, PMMV was not recorded in Lattakia, whereas it was recorded in Tartous in a small percentage (0.64%). Using Tissue Blot Immunobinding Assay, the collected seeds from the infected pepper fruits from Tartous fields showed the transmission of PPMV throughseeds in a ratio of 0.70% to 0.87% according to seed resources, whereas CMV was transmitted in a high percentage of 2.81% to 7.98% according to seed resources. PPMV was not recorded in leaf samples or in seeds taken from Blozah District in TartousProvince.

The effect of size of container in the growth of pepper seedlings "Snapper"

The research aimed to study the effect of size of container on the growth of seedlings pepper "Snapper". Two different sizes of plastic containers, with dimensions 8×8 cm and12×12 cm were used, Results showed that the use of containers with large dimensions had increased the growth of seedlings compared with the use of smaller ones. A significant increase, of about 14% was observed in the average length of seedlings and about 16% in the average number of leaves produced in the large containers as compared with seedlings produced in smaller ones. Also the fresh wet weight, whether for the plant or its separate parts was significantly higher in seedlings produced in the large containers. The plant fresh wet weight in the large container was 26.98 g vs., 2.27 g in the smaller ones.

The Influence of Treatment of Some Vegetable Seeds by OxygenatedMetia on Germination Characteristics and Seedling Quality

This study was conducted to evaluate the effect of pepper (pipiemento variety), and eggplant (Dara variety) seed's treatment on germination characteristics, and the impact of eggplant seeds treatment on seedling quality. The seeds were treated for 24 hours in glass containers, in which the ratio of seeds to the applied media was 1:5, the concentration of the mineral solution was 0.1%, while the concentration of each of GA3 and the organic nutrient solution was 0.01%. The media were continuously aerated by passing a current of pure oxygen (O2), at sufficient pressure to homogenously mix the seeds in the media. The seeds were dried up after 24 hours of treatment to remove the excess moisture. Seeds were germinated in Petri dishes, and soil-full containers to assess the germinability, and seed vigor. The eggplant seeds were also sown in peat-moss containing pots (8 cm indiameter) to study the influence of treatment on seedling quality. The results showed that treatment efficiency depends on the nature of the used media, and crop. In addition, it has been revealed that the aeration of media enhanced the germination, accelerated the seedling growth, and improved their quality.

The effect of organic fertilizer(Biotolerance) on growth and yield of some Pepper varieties in green house

This search aims to study the efficiency of using“Biotolerance” as a fertiliser; by a foliar spry on Pepper seedling. Four varieties were used (Marcony, California wander, Maroty-7 andRobber). The results showed that the treatment by the fertilizer resulted in an increase in growth thorough the plant length increasing.

Effect of Red Paprika and Local Safflower in the Diets of Laying Hens on Egg Yolk Color and Some of Production Parameters

The influence of Red Paprika and Local Safflower in the diets on yolk color was studied in two experiments of ٨ and ٥ weeks using ٩٠ and ٢٤ laying hens, respectively; Loghorn hybrids of Lohmann brown and Hy- Lain Brown strain, were used. In the first experiment, yellow corn was substituted totally by rye and wheat and ٤ different amounts of paprika or safflower were tested (٠,٢, ٠,٣, ٠,٤ and ٠,٥٪). In the second experiment the effect of sweet red paprika or hot red paprika in the diet (٠,٥٪) on yolk color or some of production parameters was studied.

Evaluating of several methods to DNA extract from pepper plants Capsicum annuum L to detect viruses belonging to the genus Begomovirus

Several protocols for DNA extraction from leaves of pepper Capsicum annuum L. were evaluated to detect Begomoviruses. The extraction methods comparison were based on DNA quantity and quality. The DNA concentration absorbance for the evaluation of DNA concentration and contamination were measured using spectrophotometer.
