This research is a continuation of previous studies on the biodiversity of the algae fuchsias to know with the aim of observing the changes that occur in the marine flora such as the emergence of new species or the disappearance of some of them in addition to studying them in terms of quantitative and biochemical terms and the changes they show according to geographical location.
The biochemical composition of some species of Phaeophyceae (Cystoseira):
Cystoseira compressa, Cystoseira barbata, Cystoseira elegans, Cystoseira amentacea,
Cystoseira barbatula, Cystoseira caespitosa, have been studied. The algal specimens have
been collected from Ibn Hani coast north of lattakia in spring 2014. The soluble sugar
varies between (13- 56.78%) weight/dry weight [w/dw]. C.amentacea has the highest
content of proteins (21.76%), and C.barbata has the lowest (9.51%). Lipid varied between
(1.25- 5.55%) [w/dw]. The highest content of ash was in C.caespitosa (31.18%), and the
lowest in C.amentacea (23.84%). Iodine was: C.compressa and C.caespitosa (0.68 %),
C.barbata (0.69 %), C.barbatula (0.7%), C.amentacea (0.71%), C.elegans (0.8%).
Mannitol was within the range (2.91-4%) [w/dw]. Results of biochemical composition of
studied species showed the differences between the percentage of values, and this variety
affects on the economical value for the species, also affects on the major herbivorous food,
that affects on their environment and their community composition.
The Studay was aimed at surveying the plant species growing in Al
Qunaitera region, their dynamic distribution, environmental characteristics
and economic values.
Atotale number of 268 species were found belonging to 170 genera at 46
families.
Only two of the founded species weren’t reported by Mouterde in his flora
of Syria.
Dairies and cheeses factories produce terrific quantities of whey in which
about 90% of them pelts into the sewerage system without making any useful of
them. Due to the valuable ingredients in whey (cheese, milk and butter). The
content can be se
parated and extracted in order to be added as a nutrient
environment in food industry. The resultant compounds (citric acid , penicillin,
amino acids and ergosterol) were identified using HPLC technique.
The Ornamental Plants (Altlfona) of important economic cultivations were introduced to the recently Syrian agriculture "as one of the most important alternative cultivations, especially" in the coastal strip, as a prospective areas for the spread of
these agriculture This research has concentrated on the economical properties and the profits resulting from Carnation plantation in Latakia Governorate studying the productivity cost and the indicatives of economical feasibility based on data and statements gathered from site of research (Arab Almelik),and relying, in determining wages and materials costs, on the current market prices in 2015.
In this research, we have sought to achieve the following targets:
- Studying the reality the production of Ornamental Plants in the Syria, in general, and Latakia Governorate, in particular, during the period from 2005 to 2013.
- Calculating the productivity cost of Altlfona plants in Latakia Governorate.
- Making an economical evaluation of Altlfona plants in Latakia Governorate.
In conclusion, we have reached the following result:
• Totally achieved net profit per annum from one greenhouse of Altlfona plantation amounted to 668212.7Syrian Pounds.
• Profitability Coefficient in proportion to invested capital has amounted to 27.19% and to 49.67% in proportion to the productivity cost.
• Time indicator of Capital recovery for Altlfona has amounted to 3.67 years.
