Salinity Effect on Important Components of Portulaca olearcea L.


Collage of Sciences University of Babylon, Iraq


The seeds of Portulaca olearcea L. were grown evenly as possible in these pots, then they were watered with tap water, and after (10 days) after the seeds germinated, each group of them was flooded with concentrations of NaCl salt, which are (5, 10, 20 ) dSm-1 and distilled water. The increase in NaCl concentration in irrigated water led to a decrease in chlorophyll a and b, carotenes, protein, TAA, and vitamin C continent. At the same time, it induced increases in both proline and TSS. Irrigated water salinity decreases vitamin C until in lower concentration (5dSm-1). They reduced each vitamin A, total alkaloids and flavonoids, and six kinds of fatty acids a-lenolic acid, ecosopentaenoic, docosahexaenoic, linoleic acid, palmate acid, oleic acid, and stearic acid, which all were decreased under salinity.
