Effect of nanoparticles of titanium dioxide (anatase) on physiological characteristics of strawberry (Fragaria ananassa c.v.Queen Elisa) in hydroponic condition

To study the effect of nanoparticle anatase on some parameters of strawberry plant (Queen Eliza) an experiment in randomized complete block design was carried out with 3 replications. Nano Anatase in seven concentrations of 0, 1/5, 3/5, 5/5, 7/5, 9/5 and 11/5 mg per liter, with Hoagland solution for hydroponically grown plants (Cocopeat) was added to 4 times a week. At the end of the experimental period (3 months), chlorophyll content, TSS/TA, vitamin C, fruit set percentage, shoot and root dry weight and yield were measured and their data analyzed with SAS software. The results showed that nano-anatase at the highest concentration (11/5 mg/ ml) was best treatment and significantly increased all the different strawberry measured traits in this experiment.
