تأثير المستخلص المائي لأوراق نبات الدفلة Nerium oleander L. على مؤشرات النمو لطحلب Lyngbya aeruginosa Menegh. ex Gomont

Abstract EN

The objective of this study was to investigate the vital influence of aqueous solution of Nerium oleander leaves extract on the indicators growth of Lyngbya aeruginosa alga.

The results were that cold aqueous extract solution of Nerium oleander leaves led to the inhibition of the Lyngbya aeruginosa growth represented on the total cells and the growth rate and decrease generation time.

The cold aqueous extract solution showed that largest of total cells number, the growth rate and the generation time, while the hot aqueous extract solution had a significant effect that increased concentrations.

The Nerium oleander leaves extract solution can be used to inhibit the growth of Lyngbya aeruginosa which was the one of the harmful algae in the aquatic environment.
