Physiological and Ecological Study of some Algae and Aquatic Plants
View through CrossRef
Abstract
The aim of the study was to find out the chemical content of some algae, Enteromorpha and Cladophora, and some selected aquatic plants, Typha domingensis, Phragmites australis and Schoenoplectus lacustris. were studied Ashes, fats and mineral elements, which include magnesium, phosphate and nitrogen, in addition to studying the physical and chemical properties of water at different times of the seasons. Enteromorpha moss showed the highest percentage of ash which amounted to (14.32%), magnesium (0.43%) and phosphate (2.73%) while Cladophora moss showed the highest percentage of fat which amounted to (7.28%) and nitrogen (3.92%). The plants showed clear significant differences in different seasons where the results showed that the highest value of ash for Typha domingensis was in spring (11.11%), for Phragmites australis in summer (12.43%) and for Schoenoplectus lacustris in autumn (16.21%). As for fats the highest value of fats was in the spring season for the Typha domingensis plant (3.10%), for the Phragmites australis plant in the autumn season (1.51%), and for the Schoenoplectus lacustris plant in the summer season (2.21%). As for magnesium, the highest value of magnesium was in the winter season for the Typha domingensis plant (0.25%), for the Phragmites australis plant in the summer season (0.76%), and for the Schoenoplectus lacustris plant in the autumn season (2.45%). As for phosphateits highest value was in the autumn season for the Typha domingensis plant (0.26%), for the Phragmites australis plant in the spring season (0.32%), and for the Schoenoplectus lacustris plant in the autumn season (0.24%). Also the physical and chemical properties of water showed great variations in different seasons as the highest recorded value of air and water temperature in summer was (41) and (40) Celsius respectively. As for the pH, the highest value was recorded in the winter season (8.16), and the nitrates recorded the highest value in the autumn season (45.35) mg / L.

Abstract
The aim of the study was to find out the chemical content of some algae, Enteromorpha and Cladophora, and some selected aquatic plants, Typha domingensis, Phragmites australis and Schoenoplectus lacustris.
were studied Ashes, fats and mineral elements, which include magnesium, phosphate and nitrogen, in addition to studying the physical and chemical properties of water at different times of the seasons.
Enteromorpha moss showed the highest percentage of ash which amounted to (14.
32%), magnesium (0.
43%) and phosphate (2.
73%) while Cladophora moss showed the highest percentage of fat which amounted to (7.
28%) and nitrogen (3.
92%).
The plants showed clear significant differences in different seasons where the results showed that the highest value of ash for Typha domingensis was in spring (11.
11%), for Phragmites australis in summer (12.
43%) and for Schoenoplectus lacustris in autumn (16.
21%).
As for fats the highest value of fats was in the spring season for the Typha domingensis plant (3.
10%), for the Phragmites australis plant in the autumn season (1.
51%), and for the Schoenoplectus lacustris plant in the summer season (2.
21%).
As for magnesium, the highest value of magnesium was in the winter season for the Typha domingensis plant (0.
25%), for the Phragmites australis plant in the summer season (0.
76%), and for the Schoenoplectus lacustris plant in the autumn season (2.
45%).
As for phosphateits highest value was in the autumn season for the Typha domingensis plant (0.
26%), for the Phragmites australis plant in the spring season (0.
32%), and for the Schoenoplectus lacustris plant in the autumn season (0.

Also the physical and chemical properties of water showed great variations in different seasons as the highest recorded value of air and water temperature in summer was (41) and (40) Celsius respectively.
As for the pH, the highest value was recorded in the winter season (8.
