EFFECT OF PHYTOREMEDIATION OF TRINITROTOLUENE ON SOME PLANT VEGETATIVE CHARACTERS OF POTATO USING NANO-SILVER PARTICLES.

Phytoremediation is considered as an early and active technique, which plants used to clean a wide range of organic and inorganic pollutants. Study was laid out to detect the effect of different levels of toluene and various concentration of silver and their effect on nanoparticles for phytoremediation and how to influence the vegetative growth characters of potato. A farm experiment was done in lath house in the farm of Horticulture and Garden Architecture Department, College of Agriculture, University of Anbar for the spring season 2021, to study the effect of phytoremediation of potato, Class Burren of elite order. Different levels of tri-nitro toluene were added with different concentrations of nanosilver particles directly into soil according to the study treatments and variation. Results stated the superiority of treatment T8 (500 mg kg_-1 soil TNT+500 mg kg_-1 NPs) to give maximum height 61.56 cm with a highest average leaves number as 47.66 leaves. plant, in addition to the dry weight 55.02 gm and stems number 3.66 for the same treatment, in addition to give a highest dry substance percentage as 16.55%, compared with the control treatment that recorded (36.06 cm, 41.6, 33.32 g, 2.33, 13.27%) successively; while the treatment T7 recorded highest leaf area of 119.79 dcm². It could be derived that the treatment at level (500x500 TNT-NP_S) possessed a positive effect on potato vegetative growth characters. [ABSTRACT FROM AUTHOR]
