Abstract

The research aimed to study the effect of potassium humate treatments on growth and yield of the potato ‘Spunta’.  The experiment was carried out during spring season of 2018 in Banias. The experiment included four treatments (control without treatment, spraying plants, soaking the tubers, spraying the plants and soaking the tubers). The experiment included 4 treatments with four replicates for each treatment and at a rate of fifteen plants  for each, according to randomized complete block design. In general, the results showed that potassium humate caused stimulation of vegetative growth. This was shown in accelerating the germination of tubers, increasing plant lengths, number of leaves, leaf area, leaf area index, number of tubers and plant yield. This effective was more evidence in the treatment of  tuber  soaking + spraying of plants. This treatment showed significant superiority in leaf area, plant  yield, dry matter and starch contents of tubers. The highest values which were recorded compared to other treatments, in terms of dry matter 19.6%, and the percentage of starch 13.5%, compared to 14.9% and 9.3% for control.

Abstract

Knowing the interspecific and intraspecific differences of Mentha species is not easy, this is due to the polymorphism and variations in morphology and anatomy characteristics. Because of lack of local studies, it was necessary to taxonomically highlight some local Mentha species, so the aim of this research was to conduct a comparative study of the qualitative and quantitative variations of three local species of Mentha, to find out the distinctive and differentiating taxonomic characteristics for each species. Biometric measurements were taken to cover all stages of the plant’s morphological development including flowering and fruiting. The studied traits included 39 qualitative characteristics and 38 quantitative characteristics. The three studied Mentha species were identified as: Mentha longifolia, Mentha piperita, and Mentha spicata. The studied species showed morphological and anatomical differences, for instance, the stem was hairy in Mentha longifolia and glabrous in the other two species, as well the leaves were velvet on both sides in Mentha longifolia and glabrous in the other two species with the exception of some few and short micro hairs on the margin and the apex of the leaf in Mentha piperita, and the leaves were petioled in Mentha piperita and either sessile or sub sessile in the other two species, Mentha longifolia was unique in the presence of hairs on the corolla, calyx, and flower pedicle. As for the quantitative characteristics, Mentha spicata possessed the largest diameter of peltate glandular trichome of 77.55 micrometer, and the largest length of fruity spike of 11.03 cm. The results indicated the variation of the studied species in a number of morphological and anatomical characteristics such as; the shape and dimensions of leaves and inflorescences, dimensions of the hairs and glandular trichomes, shape of pollen grains, length of polar and equatorial axis.

Abstract

Man has known the gardens since ancient times. Gardens have emerged since the beginning of human agriculture around houses, because of their spiritual and economic benefits. However, with time, techniques were developed for cultivation and irrigation, after that man started to think of entertainment and comfort, so he has been interested in plants species that please his eyes. Landscaping is considered an art of no less importance than other types of arts such as music and painting. It reflects the extent of human development, the development of techniques and the breadth of imagination. The presence of gardens is not modern, but is characterized by modernity and ancientness at the same time. The human view of the garden has not changed throughout the ages. It is a symbol of renewal, vitality, self-comfort, and an attempt to escape the burdens of life. Man has developed and transferred gardens from one country to another, so that different kinds of gardens have emerged. This research highlighted on the roof gardens of Arab scientific heritage, which were discovered from heritage texts, where these gardens were mentioned in the century (5 AH / 11 AD) and were overlooked in many sources and references. The types of cultivated plants were mentioned in the heritage texts, and the method of planting and transporting them was also mentioned, irrigated and coordinated. These gardens served as a lung and a respite of the building, adding an economic revenue to the population.

Abstract

Some juveniles fish and fingerlings prefer coastal estuarine environments for feeding, growth and reproduction. This research was done at three rivers estuaries of the coastal waters of Latakia i.e. AL-Kabir AL-Shamali River, AL-Sanawbar River and AL-Qandil River, during the period Jan. 2014 to Dec. 2015. Each station was divided into three different sampling sites: fresh water station (river stream), estuary station and a marine station. Fish were collected bi-monthly and several fishing methods had been used for this purpose. Some of the physical and chemical properties of the water were measured, and the locations and times of fingerling presence in the estuary were determined. Results revealed the presence of 42 fish species, distributed over 22 families and 6 orders. The largest number of species was in AL-Kabir AL-Shamali station, then in AL- Qandil station and finally in AL- Sanawbar station. The results revealed the existence of several fish species, which may be used in mari culture.

Abstract

This study was conducted for the first time at Syrian coast, by the aim of investigating the fauna of monogenean helminthes of economically important marine fish/ Genus Diplodus sp., breed in Al-Sinn fish farm, and their dynamics between natural and cultured environments. The study showed that fish samples (18 fish) of the genus Diplodus caught from Al-Sinn fish farm, belong taxonomically to two species: Diplodus vulgaris (Linnaeus, 1758), and Diplodus cervinus cervinus (Lowe, 1838). The results of the microscopic examination of wet smears taken from fish gills of Diplodus vulgaris, and Diplodus cervinus cervinu, showed the presence of a single species of monogenean helminthes belongs to genus lamellodiscus sp. (L.). L. elegans infected the gills of Diplodus vulgaris with a prevalence rate of 88.88%. The results of this study confirmed the interference of the parasites community in the natural marine environment and in the cultured environment. The Lamellodiscus elegans is one of the pre-recorded species on the gills of Diplodus vulgaris in the Syrian coast. The fingerlings of the fish that are raised were obtained from marine environment, not artificial hatcheries which could explain this interference between the two environments.

Abstract

Sardines fishes (Sardinella longiceps) were brought from the Iraqi regional marine waters, Basra, during March and April 2019, to study the natural food selectivity using Manly`s ά index to determine the natural food selectivity, and food ingredients percentage, besides fullness index. Fish samples were transported to the laboratory using a container of cork after adding crushed ice to reduce food losing during transporting, where the average of total length was 16.2, 17.7 cm and the weight average valued 26.586 and 29.934 grams during March and April respectively. The results showed that the stomach fullness index attained 55 and 85% of all samples and fullness index reached 40.39 and 62.77 during March and April respectively. The percentages of nutritional components inside the stomach were as follow: animal`s remains 36%, crustacean`s remains 27%, fish`s residues 12%, phytoplankton and diatoms 17% and other digested materials 8% during March, while in  April the values were as follow: zooplankton 33%, crustacean`s remains 18%, fish`s residues 10%, phytoplankton and diatoms 28% and other digested materials  11%. The results showed that the food of the fishes from an animal`s origin was the prevailing food in the stomachs with an average of 0.25363, 0.21035 and 0.19804 of zooplankton, fish`s residues and crustacean`s remains from the total food during the study respectively .

Abstract

A digestibility experiment was carried out using 45 unsexed chicks of a commercial broiler breed (Ross 308) which were taken from a hatchery nearby an experiment farm. Breeding started in 23/9/2017, to estimate metabolisable energy values of diets that feeding to chicks in first week of its life. Chicks were collected without need to complete operation of hatching to ensure chicks to be hatched at the same time. Chicks were placed in special cages that meet their purpose, to determine the amount of feed and chicks manure resulting from each studied group. Chicks were distributed into three groups, and each group divided into 3 sub-groups, where each sub group contains 5 chicks. Chicks were fed different diets as follows: Chicks of 1st group were given broiler diet directly after hatching (control group). Chicks of 2nd group were given broiler diet contain 5% glycerin directly after hatching and chicks of 3rd group were given broiler diet contain 5% corn starch directly after hatching. Groups were fed (Ad-libitum) until the end of the experiment at the age of 7 days. The results showed that adding glycerin 5% in broiler diets increased apparently metabolisable energy and true metabolisable energy in this diet with significant differences (P≤0.05) compare with control group and cornstarch group. The results showed also that adding cornstarch had no significant differences (P≤0.05) compared with control group. The results showed no significant differences in average live weight of all groups studied at the end of first week.

Abstract

Samples of artificial fish diets was brought from three selected private fish farms as a selected stations that were marked as A, B and C, to represent the stations in the south, central and north of Basra, respectively. Storage and stores  conditions were studied and microbial content lesson to the samples from the fish diets  after 20, 40 and 60 days of storage, using isolation and diagnosis of colonies using scientific sources, and the bacterial counting method. Microscopic colonies of microbial growths were identified. The results showed the presence of fungal and bacterial growths in all diets. Also, the results of examination, isolation, and diagnosis showed the presence of the following types of organisms that included each of the fungal colonies: Penecilum sp., Aspergillus niger, Aspergillus falvus, and Mucor sp.). The identified bacteria were: Staphylococus epidermis, Bacillus sp., Strptococus sp., and Diplococci sp.). Their difference in proportions depended on the sample source and the time period of storage, and at a total count rate for the colonies during the study period of the bacterial colonies were Staphylococus sp. (14), Bacillus sp. (16), Strptococus sp. (14), Diplococci sp. (12), the innate Penecillium sp. (23), Aspergillus niger (26), Aspergillus falvus (25), Mucor sp. (25) for station A, and for bacterial colonies Staphylococus sp. (22), Bacillus sp. (19), Strptococus sp. (17), Diplococci sp. (17), the fungal Penecillium sp. (30), Aspergillus niger (32), Aspergillus falvus (28), Mucor sp. (24) for station B, and for bacterial colonies Staphylococus sp. (31), Bacillus sp. (27), Strptococus sp. (22), Diplococci sp. (25), the innate Penecillium sp. (33), Aspergillus niger (37), Aspergillus falvus (36), Mucor sp. (29) for station C, with a clear increase with increasing and worsening of storage period and  using the older diets feed. According to that, the result showed that the percentage of microbial growth was the highest at station C compared to stations B and A.
