Abstract: 

This experiment was carried out in Miaar Shaker village (Tartous) in agriculture season (2020-2021) with the aim of studying the effect of spraying with salicylic and ascorbic acids on growth, productivity and quality specifications of the fruits of tomato plants in greenhouse. The design of the randomized complete sectors was followed, and the experiment included 9 treatments and 4 replications. The results showed a significant increase in growth and productivity indicators when spraying with salicylic and ascorbic acids compared to untreated control. The use of a mixture of salicylic and ascorbic acids at a concentration of 400ppm each led to a significant increase in productivity which is (5.90 kg/plant) compared to (2.94 kg/plant) for control plants. The content of vitamin c of the fruits increased when treated with a mixture of the two acids reaching (34.29mg/100 g fresh matter) while it did not exceed (18.30 mg/100g fresh matter) in the fruits of the control, in addition to improving the quality specifications of the fruits, including indicators (dry matter, total sugar ratio and solidity fruits…). The use of the spraying treatment of salicylic and ascorbic acids lead to a decrease in the percentage of nitrate in the fruits(53.74ppm)  compared to the  control (109.94ppm).

Keywords: Tomato, Salicylic acid, Ascorbic acid, Greenhouse.

Abstract: 

The response surface methodology was used to determine the optimal proportions of different diameters of Golan 2 wheat bran to produce Arabic bread, to verify the impact of two independent variables: the ratio of addition and the size of bran diameters on the response factor, namely the rheological characteristics by Mixolab apparatus and the sensory characteristics of Arabic bread. This study was carried out in the laboratory of the Department of Food Sciences at the Faculty of Agriculture university of Tishreen university and in one of the private ovens between 2020-2021 The experimental values were selected based on the results of the initial experiments where bran diameters greater than 1000 microns were excluded as a result of their negative impact on various rheological and sensory properties, less than 1,000 microns of bran were used at ratios (5-20)%. It was found that the optimal conditions for the maximum use of bran while maintaining sensory characteristics are 250 micron diameters by 14.1%, where the tests of Mixolab showed that the reduction of bran diameters reduced the time needed for the development of dough and gave longer time in the stability of the dough, and the results of baking showed the increase in the rise of the loaf with the decrease in the size of bran diameters, this indicates improved quality properties for the resulting bread.

Abstract: 

The aim of the research to studying and evaluating the impact of saponins in quinoa seeds using treatment wet and dry methods, and the impact of these factors on the taste properties of the quinoa seeds. Work on the quinoa class /NSL-106398/ was planted at the Agricultural Scientific Research Center in Hama during the 2020 season, was tested /8/ different coefficients in the dry and wet methods using normal water, /4/ different coefficients in the dry and wet methods using alkaline water (0.1n NaoH) different at the time of soaking, boiling and roasting to determine the best treatment (with the lowest saponins, best taste). The results showed the treatment (8) which were (seeds washed with water and soaked for 24 hours + shaking with shawl water and dragging of foam for 30 minutes + boiling of seeds for 30 minutes + roasting of hot air + roasting to light brown.) was the best to dispose of bitter bait and to obtain high tasty Specifications, with an average of / 4.93/ with a very good final score on the Lykart scale, followed by treatment (7) (seeds washed with water and soaked for 24 hours + shaking with shawl water and dragging of foam for 30 minutes + boiling of seeds for 15 minutes+  roasting to light brown) with an average of my account /4.60/, and treatment (11) (seeds washed with normal water and soaked for 3 hours + alkaline water treatment 0.1 n + boil seeds for 15 + hot air drying + roasting until light brown.) with an average of my account /4.60/ and with a very good as result on the Likert scale, the research indicates that these parameters are used to get rid of the bitter taste in the quinoa seeds and insert them into local meals whether whole grains or flour added as supporting material.

Abstract: 

The current study aimed to evaluate the use of flax gum and Arabic gum obtained from the local markets of the province of Mosul and to study the physical properties and the possibility of using them in the food industries, including ice cream. The results of the sensory evaluation of the produced ice cream showed the possibility of using Plant gums in the manufacture of milk ice cream, as the flax gum showed a desirable flavor to the consumer as it was similar to the flavor of walnut, while Arabic gum did not appear in it for its crumbly ice texture. The percentage of yield for gum flax is 81%, which is a very good percentage compared to Arabic gum, as it was 45%, which is a very low percentage, and it was found that it is somewhat unsuitable for its use in milky ice cream. The deflation rate in flax gum was 3.7%, and in Arabic gum, it was 0.33 because there is a direct relationship between rent and deflation. The rate of beating after the 15th minute was 80% in flax gum, and it decreased significantly in Arabic gum, reaching 45%. The percentage of Fusibility in flax gum after 30 minutes was 33.3%, while the percentage increased in Arabic gum by 71%, where the Fusibility is affected by several factors, including the amount of air combined during mixing and ice crystals.

Keywords: flax Gum, Arabic gum, yield, the phenomenon of deflation, ability to whisk, Fusibility property.

Abstract: 

Tomato leaf miner, Tuta absoluta (Meyrick, 1917) (Lepidoptera: Gelechiidae) is a dangerous and difficult pest to manage because of the larval feeding habits, it is attacking all aerial parts of the host (leaves, stems and fruits) cultivated and wild plants with a high preference towards the species of Solanaceae plants especially tomato and other Solanaceous crops in greenhouses and fields. The aim of the study was Survey and Identification of new species of Hymenopteran Parasitoids from Larvae of Tomato Leafminer T .absoluta (Meyrick).The samples of infested tomato plants by Tomato leaf miner T. absoluta were collected from a greenhouse and fields during (March/2019 to August/2021) from Lattakia and Tartus provinces. The species were identified by using specific keys to subfamilies, genera and species, they belong to four different superfamilies: Ceraphronoidea, Chalcidoidea, Chrysidoidea, Platygastroide. And three species and two genera: Aphanogmus clavicornis Thomson, 1858 (Ceraphronoidea: Ceraphronidae) Larval actoparasitoid, Goniozus nephatidis (Muesebeck) (Chrysidoidea:Bethylidae) larval gregarious Ectoparasitoid, Pteromalus sp. Swederus, 1795 (Chalcidoidea: Pteromalidae) larval Ectoparasitoid, Diglyphus isaea (Walker 1838) (Chalcidoidea: Eulophidae) larval gregarious Ectoparasitoid, and genus  Telenomus sp. (Platygastroide: Platygastridae) egg parasitoid. The most widely spread of these species was Diglyphus isaea (95 adults)(75.39%) then genus Pteromalus sp. (9 adults) (7.1%),and Goniozus nephatidis  (6 adults) (4.7%), followed by Telenomus sp.

F. oxysporium  had  been defined from  the fungal community, eight isolates of F. oxysporium. f. sp. tuberosi  (FOT) monospores according to Van Dieghem by using the Hanging Drop method. Isolates were identified morphologicaly and microscopically. The pathogenicity tests of the isolates were carried out stem and roots of potato plantlets (cv. Spunta). The data was recorded on four replicate (plantlets) from each treatment in addition to the control after 60 day from infection by standard for the stems and roots between (0-5). The results revealed that isolate FOT23 was the most virulent compared with other isolates, While the isolate FOT28 was the least virulent.
