| description | Soil salinity is a process of increasing salt in soils. It has become a problem since it
keeps spreading geographically from coastal areas to other fertile lands. Therefore,
many plants have developed some series of adaptations to mitigate against salinity.
Salinity limits the vegetative productions and changes the ecological health of
estuaries due to unproductive lands. It lowers the crop yields for daily purposes as well
as a threat for biodiversity in which living things loses habitat for both land and in
water. Thus, the purpose of this study was to evaluate the growth traits of Clitoria
ternatea var. plenifora exposed to different concentrations of sodium chloride, NaCl.
Accordingly, it also brings insights into the effect of various concentrations of salt
stress on the qualitative phytochemicals content of tannins, flavonoids, glycosides,
steroids, terpenoids, alkaloids, phenols and saponins. Moreover, the total phenolic and
flavonoid contents were determined quantitatively. Ferric reducing antioxidant power
(FRAP), 2,2’-azino-bis (3-ethylbenzothiazoline-6-sulfonic acid (ABTS) and 2,2-
diphenyl-1-picrylhydrazyl (DPPH) assays were conducted to evaluate the antioxidant
activities of the Clitoria ternatea var. plenifora. Thus, the results from this study
revealed that all of the test growth traits ̶ the number of branches and leaves, height of
plants, fresh weight of leaves and dry weight of stem, leaves and roots ̶ were the highest
under 200 mM of NaCl treatment. Apart from that, under 200 mM of NaCl, Clitoria
ternatea var. pleniflora was shown to contain the highest total of phenolic and
flavonoid contents among of all the salt stress treatments. Thereupon, the antioxidant
activities of FRAP, DPPH and ABTS were also showed to reach at their highest
activities under 200 mM of NaCl. In conclusion, 200 mM of NaCl is the optimum
concentration for Clitoria ternatea var. pleniflora to improve the growth traits,
phytochemicals and antioxidants of Clitoria ternatea var. pleniflora. |
